Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and system for obtaining two-dimensional or three-dimensional coordinate data 5 in space, particularly, but not limited to, related to obtaining One of the coordinate information is a set of positioning components and supporting hardware and software. In general, a group of units is a bit that may determine another unit that is generally associated with itself. Background of the invention Small space positioning, that is, positioning in a few meters or less space, including some fields, mainly for computer interaction And robots and machine control indicators, but also include toys, equipment control and other areas. Some applications may require 20 measures. Others may require 3D measures. In addition, some applications, such as pointing devices, may only require one-way communication, however, for example, a robot may require two-way communication. 1) Instructed reading pen — The digital pen is used for electronic detection of handwriting or hand-painting, or for indicating instructions for general instructions. Digital pens are commonly used, such as sound waves, light and light technology. Other forms use an accelerometer that senses acceleration and transmits data to the base station. The other form is a camera that analyzes the small print code on the special paper two to determine its position. The other pens, Wei Tian, use electromagnetics (including passive and active), as well as other technologies for their operation. Some digital pens are 20 1298799 autonomous units, meaning that the pen is independent of the guard, and provides its unique fully processed coordinates as an output, and this is a typical optical and digital camera-based unit. Additionally, especially for sonic and electromagnetic devices, two sets of receiving or sensing units are required. Digital pens are widely used in personal computers, laptops, personal digital assistants, mobile phones, e-books, and the like. Dynamic white handle: 10 15 . The interactive whiteboard is a kind of whiteboard that captures the written data from the board and enters the connected computer. A typical technique in this field is sonic positioning: the marking device is placed in a sleeve that transmits the beacon signal that is acquired and analyzed by a dedicated device that is close to the whiteboard. In some instances, the compensating electromagnetic signals and the acoustic beacons are transmitted to: with better accuracy and simplification. Another typical technique is electromagnetic technology. 2. The above-mentioned marking device sleeve transmission-electromagnetic field is obtained by the special circuit of the whiteboard. Resistive technology is also used at the same time. In this case, the surface of the whiteboard is broken with the material of the electric Chen. Pressure is applied to the coating and the pressure conducts a localized change in the sheet resistance properties. Due to this change, the controller is able to obtain an X, y position from the pressure of the break. Capacitive technology, which is similar to resistive technology, can also be used: again, pressure is used to change the nature of the plate's capacitance. Then the controller may get the X, y position. Touch screens typically include a sensor that is embedded in or near the computer screen to receive input from the screen. Some techniques involve coating the screen with a special material that is perceived to be in actual contact, and the material can be any resistive, capacitive, and SAW material. Other techniques include embedding the perception near the screen. The perceptron can be IR, sound wave, SAW, and 5 others. 3-D mouse: The 3D mouse uses electromagnetic or ultrasonic positioning techniques to indicate its position in the 3_D space to a monitoring device. The wireless mouse used today is an IR transmitter that uses a Blue Tooth device and similar radios and is used for wireless connection. Radio or IR only handles wireless connections, which is a signal issue. The 疋 position is generally included in the mouse itself as a mobile tracker. Simple mobile tracking produces a 2D result. The 3D result can be generated, for example, by any of the following methods: 1) The swaying mouse emits the ultrasonic wave received by the desktop receiver and the 15 IR pulse wave. Triangulation can be performed by measuring fast moving time. 2) IR sensor: The mouse emits an IR pulse that measures the angle of the desktop receiver. Many angle sensors allow 3D triangulation to be achieved, so a special position is achieved. PC board and drawing pin: 20 pc board use - digital pen or tracing needle. The pin-and-pin interaction involves writing directly to the green board, pc board, pc screen, pda screen, phone screen, and any surface, screen, or board interaction on the computer being steered. Actuated or active electromagnetic or acoustic techniques are available. Disadvantages 1298799 The available technical measures are subject to the following shortcomings. It should be noted that these shortcomings can be applied to the applications discussed below: All of the above measures require significant computational intensities, and amplification and digitization circuitry. They do not use the resources available to the host computer; instead they use 5 dedicated hardware to perform their unique calculations and feed the processed tribute to the computer. Dedicated hardware is expensive and complex, and is especially wasteful in terms of the computing power available to the host computer. All of the above techniques, in addition to sonic technology, require a perceptron on the positioning plane: the electromagnetic method requires an antenna loop on the back of the board, and the pen of the camera requires special digital paper and the touch screen needs special coating. The perceptron needs to add the cost of the final product, and further stipulates an unreasonable usage limit that does not allow the user to use any plane, such as a messy desktop, as a work platform. The complex circuits and perceptrons of these measures require dedicated space. It is not possible to combine this measure with a small and hand-held device that is not explicitly designed, such as a PDA, mobile phone, and the like. This argument is also clearly applicable to laptops and other mobile products, where the small size allows for a clearly designed positioning installation, but does not allow the free use of any device. The mounting of hardware components on a PC is tedious and not always reliable. 2〇 When a new feature is added, it is significantly easier to use components that have already been installed, such as a sound system that exists. There are currently no interactive platform measures available: a positioning method for touch screens is different from digital pens for the active phone market, etc. Because of the small size and complexity of the planning, the integration of available measures for existing products is usually No benefit. At the clerk, all available measures require a redesign of the final product. < 4 There is no need to add software to the computer to increase its functional processing. /, Support for most user applications is not easy and currently only available is Blue Tooth communication media. Bluetooth is still limited to eight simultaneous users. The measures available at Peak require a large amount of power supply. These technologies are limited to one-dimensional locations. Even those that can handle three-dimensional conditions still do not provide accurate three-dimensional information. For example, according to the electromagnetic test ✓ the 彳田画针 ▲ can be detected when it is left on the screen, but it is impossible to accurately show how high it is. The detector simply determines its presence. Some technologies have their specific drawbacks. For example, it is difficult to effectively work in the sun. Existing sonic measures are severely limited by the noisy environment on sound waves, especially in the most important industrial environments where voice noise is most prevalent. The use of wireless protocols, such as Bluetooth, may be compromised by protocol conflicts and interference from other wireless devices, such as WLAN devices. Of course, touch screen measures are inherent two-dimensional measures. 2) Robot and machine control Robot and machine control are the areas in which the position sensor is used to control the movement of moving parts. Industrial robot 1298799 The robotic arm can perform a combined task of 3D space that requires careful handling. The PCB combination machine performs the placement of the electronic components of the 2-dimensional printed circuit board. CNC machines perform cutting and drilling tasks that require high resolution. The car combination line uses an automatic drilling machine and uses high spatial precision to drill the body. 5 Fax and Printers Fax and printers have precise position sensors for sweeping, printing, paper positioning, and more. Free-Motion Robots In recent years, many new robot products have reached the prototype stage and have exceeded 10 times. Robotic products contain free-flowing robots for different applications. These applications include mowers, pond cleaning, robots with cameras and remote control surveillance and bomb disposal, and more robots. This robot typically uses their unique perception and pre-planning to find their way around their surroundings. 15 New applications may include an automatic vacuum cleaner. One or more sets of vacuum cleaners can automatically travel around the vacuuming site, vacuuming and delivering the dust to the positioning unit or travel unit. The dust suction unit can automatically position the receiving unit that transports dirt and dust to the place to transfer the dust. The perceptrons used in the robotic applications described above use the following techniques: 1) Optical encoders: These perceptrons include a rotating wheel with small holes around the wheel. An LED and a light sensor are mounted on either side of the wheel. The light sensor receives a sequence of light waves as the wheel rotates (due to the movement of the robot). Light waves encode the precise angle of the wheel, thus revealing the position of the 10 1298799 moving arm. These perceptrons can also be used as linear perceptrons, meaning that the perceptron is not buried in the rotating system but in a straight line. Buckle 2) Potentiometer: These sensors are grounded and attached to the moving object. The perceptron changes its resistance as a function of its position. 5 3) LVDT: These are magnetic sensors, which consist of two parts: one is the core and the other is a magnetic cylinder. When the core is moved inside the cylinder, the magnetic change of the cylinder acts as a function of this position. 4) Those skilled in the art will appreciate that there are additional techniques that are less commonly used. 10 All of the techniques described above for connecting robots are relatively large scale. All of them need to be attached to the moving part of the robot in one way or another, and there is no special measure for attaching the sensor to the tip of the moving arm/mechanical person or the like. Frequently, accuracy changes with cost, making precision equipment expensive. A perceptron with high accuracy over a distance of a few meters may cost hundreds of thousands of dollars and is not economically implementable for the imagination of many robots. 3) Sister Because of the cost, it is relatively uncommon for one of the toys to know the location of the other unit. 20 In a very basic example, a toy notices that another toy is nearby, suggesting a reaction, such as speaking. In a more refined example, a toy has more or less knowledge of where another toy is. In the future, it is desirable to provide more sophisticated examples in which one unit can successfully pass an object to the next unit and vice versa. Further, the future 11 1298799 toys are imaginable, with 22 groups of soccer robots moving around and transmitting football to each other. The robot calculates the kick position based on the positioning of another robot on the same and relative teams. Providing groups of twenty robots with computational and control capabilities to play football, resulting in a very expensive and complicated solution. In general, toy technology must be provided at low cost and is relatively expensive in the current state of the art. Each particular technology has its drawbacks: Infrared Sensor-IR can be used to indicate the presence of a second object. It can display a general direction at a higher level. The shortcomings of the accelerometer-accelerometer are discussed in the section on indicating devices above. Acoustic-acoustic devices are relatively expensive. Only a single unit can be used in the same environment, energy usage is relatively high, and it is not easy to miniaturize the device. 15 Therefore, it is widely understood that it has a high advantage and is a positioning system that is free from the above limitations.

[Embodiment] 20 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The present disclosure discloses a system for using a continuous waveform ultrasonic signal and/or using a detector having a plurality of receivers to determine the positioning of the positioning element. The input is multiplexed and entered into an analogy that is convenient for computing clothes that require interaction. The computing device uses the resources it owns to resolve the 24 1298799 and determine the location of the pointing device. In one set of embodiments, the synchronizing combination of the / 仏 疋 ultrasonic and infrared signals. In a progressive embodiment, the detector can be a separate set of independent output devices that can independently output a continuous waveform. Another argument for the disclosed embodiment is the ability to decode t for position detection using low processing. The principles and operation of the pointing device and system in accordance with the present invention will be better understood with reference to Figure 100 and additional description. (7) Before the at least one set of embodiments of the present invention is described in detail, it should be understood that the present invention is not limited by the component and component configurations shown in the following description or in the drawings. Further embodiments of the invention may be practiced or implemented in various ways. It should also be understood that the phrase and specific terms used herein are used to describe and not to be construed as limiting. Referring next to the drawings, FIG. 1A shows a group operation positioning detection system in accordance with a preferred embodiment of the present invention. The right 4 is designed for use with the computing device 10 incorporating the J standard analog input 12. The system includes a set of positioning elements 14, arranged.兮A, which occupies a detected position

The 5 疋 疋 元件 可以 可以 可以 可以 可以 可以 可以 可以 可以 20 20 20 20 20 20 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 Mouse or similar, game component or any other kind of wear A# or for the game to be tracked and the computer uses the movement of the component. The movement of the j-position element 14 is used for wheeling. General slippery or similar ^ set = positioning as any pin should be drawn to help with position tracking. It facilitates mobile tracking, while a group and game components can be positioned or moved in accordance with one of the 25 1298799. In either case, the positioning element simultaneously obtains a set of positions and transmits a signal that can be decoded to determine the position. If the positioning element moves on a track, for example, an indication of the dot curve 16, an appropriate application can track the corresponding curve 18 on the computer screen. Similarly, a 5-bit component can be used to write directly to the screen. The system further includes a set of detector configurations or base stations 20 that detect signals transmitted by the positioning elements 14 in a manner that allows for positioning. That is, the signal is designed to contain sufficient information to induce signal processing to determine the position of the positioning element. Preferably, the signals are detected by two or three separate detectors 22 that are spaced apart. The number of detectors 22 is preferably selected for the desired number of coordinates, i.e., the number of dimensions required to follow the movement of the indicator. Preferably, the base station itself does not use the signals to calculate the coordinates of the pointing device, but rather multiplexes the signals together on a single channel. This channel is then provided 15 to the analog input 12 of the computing device. The computing device only needs to demultiplex the signals received on its analog input and complete triangulation or the like to assign coordinates to the pointing device. In a preferred embodiment, each detector picks up the same signal from the pointing device. However, since the detectors are at different positions, the phase difference or time lag or the like is extracted, so that a position can be calculated from the difference between the detected signals. There are a number of methods for providing signals that allow for position detection or to introduce the above differences. A preferred option is to instruct the device 14 to transmit a combination of signals having different rates. The receiver can then calculate the distance of the receiver using the difference between the two sets of signal arrival times. The ratio of the distance between the two sets of receivers 26 1298799 allows for the calculation of a set of two-dimensional positions and the comparison between the three sets of receivers allows calculation of a set of three-dimensional positions. Preferably, the indicator device 14 uses a combination of a speed of light signal (e.g., an infrared signal) and a speed of sound signal (e.g., an ultrasonic signal). The distance to each receiver 5 is then calculated from the difference between the two sets of signal arrival times. It will be appreciated that the arrival of the 'infrared signal is actually instantaneous, so the base station 2 can be simplified to have a single infrared sensor 24, and two or three component perceptrons 22 can be used to perceive only the ultrasound.

In a preferred embodiment, analog input 12 is any input having access to an A/D 1 converter. A typical example is input from a microphone to a sound card. Another example is input to the sound card by the incoming line, and the modem input can also be used at the same time. Typically, the sound card has sufficient processing power for demultiplexing and processing the ultrasonic signals, as discussed in more detail below. If a sound card is used, the microphone input is advantageous because it can supply power to 15 base stations. In this embodiment, by using analog input and on-board processing capabilities, any machine that can digitize analog audio money is ignited, for example, % and larger = brain: laptops and PDAs, mobile phones, and other computing Pack 20

The smaller computers are added to them. In the case of PCs and hands, the processing power can be conveniently used in practice for digital sound capabilities on some machines. Calculation = this: into 2 body in the indicator device and sensor, while using very small! Ben: Two? Originally to compensate for simple hardware, and even a large number of positioning instructions are advantageous, as explained in 27 1298799 below. As described above, in a preferred embodiment, a set of standard microphone wheels is used as an interface between various different sensors for position detection, which may be microphones, light detectors, antennas, and the like, and Calculate 5 devices. In this embodiment, the device having free input that is sampled by the Λ/D circuit can use this embodiment to provide positioning capability without having to change any hardware within the device. In a typical installation, A/D sampling is performed after filtering and amplification. It will be appreciated that the appropriate client software is preferably placed within the computing device 10 to obtain location data from the original input signal. While this embodiment uses microphone input, it should be understood that any analog input is also appropriate. Many PCs and laptops have more than one set of analog inputs, such as microphone input, incoming line input, and data wheeling. The inputs of these analog inputs can be used as a connection to the positioning system described herein. However, the microphone input has some advantages over the other analog rounds. In particular, the power for the base station can be obtained from the microphone socket, and thus there is no need to separately connect the power sources. One disadvantage associated with modem input is that many modems do not have the ability to transfer raw data from the modem socket to the PC memory. Instead, the data transmitted from the data processor is automatically processed as data engine power. The general disadvantage of the modem and line inputs is that the amplitude sequence signal level on the modem input and line input must be higher than the level of the microphone on the microphone wheel ^ 0 】. This makes the positioning system need to add additional complexity. Reference is now made to the claims, which is a simplified block diagram showing a second preferred embodiment 28 1298799 of the present invention. The same reference numbers are given to the same parts as the previous figures and are not to be used except for the limits necessary for graphical understanding. The embodiment of Fig. 1B is a decoding of a signal that is received at the base station and that is not received by the device. Therefore, the base station 5 may output digital coordinate positioning information regarding the movement of the pointing device 14. Therefore, the base station does not need to be connected to analog analog 12 but can be connected to any suitable digital input or can be used separately. The positioning system of Figures 1A and 1B comprises three parts: 1. A set of positioning elements 14. As noted above, the locating element can be a mouse, a 10 stylus, or a stylus, or can be a mechanical or a group of robots or a game component in the game or any location whose position may need to be traced. Another component. For example, a board game or similar can use the game components of all of the positioning elements in accordance with the present embodiment. 2. Perceptron array 22 and pre-processing hardware, which are preferably configured together 15 to base station 20 that is coupled to analog input 12 (e.g., a microphone jack). In Figure 1B, the CPU can be added to allow full processing of the data in the base station 2, so the actual absolute or relative coordinate information is transmitted to the input of the computing device by #. Group standard digital inputs can be used instead. Alternatively, the embodiment can be reserved 20 for use alone, in which case it supports its own application and is not connected to the computer. 3. Including the client software of the group-discrete method, which decodes the signal information and outputs the positioning. It is noted that 'client software can be provided with the system as a system driver benefit' or can be used in conjunction with the operating system or as part of an application that intentionally uses location data. = Non-only for the system - (4) Table contains: This: - The group standard screen is a group, type screen ''.

The same principle applies to writing boards or surfaces of any other nature. The pressure is 疋-type piezoelectric crystal. In addition, it has a sensing element attached to a standard whiteboard. In addition, the result looks and feels on the digital tablet: on one, 纟 and 娄 ^ ^ ^ α ^ , on the slap writing board, standard Α 4 or any other size paper can be used, detectable movement and produce pen Electronics:: Placed in the adjacent base station • Games. As mentioned above, the fixed type is (4). The display device can be used in the game department • digital tablet and interactive electronic check • digital signature application, for example, including the ability to obtain unique digital signatures and use them for document authorization confirmation and Fu Xianyi. This application will be explained in more detail below. • Robot application (refer to the previous block) • Digital pen for mobile phones/pda/pc, etc. • Toy and game type applications.

3〇 1298799 • Device tracking application. Preferably, the user is supplied with the sensing array device or base station 2 and the pointing device 14. As will be explained in greater detail below, indicating device 14 is preferably a transmitting acoustic wave, and an IR or electromagnetic signal. The transmitted signal directs the array or computing device or a combination thereof to calculate the location of the indicator and provides the calculated location to the regional operating system or application. The principle of the quick-action system will be entered as an analogy to the interface to a computer or similar device. A particularly useful set of analog inputs is the microphone input and is the interface to the standard microphone 10 wind input. The following questions are considered: 1. PCs, PDAs, and mobile phones typically have only one set of microphone inputs. However, the perceptual array has two, perhaps more, perceptrons, and at the same time is also required to provide input for a standard microphone. As explained above, the problem of inputting signals from a plurality of sources to a single set of microphone inputs can be solved relatively easily with multiplexing. There are two preferred multiplexes, time divisions, and frequency division multiplexing. 2. The general and wide-ranging sound card type for the Sound Blaster®, the input broadband is no more than 22 kHz for most advanced modes. In fact, in order to provide a system compatible with earlier modes, 20 is preferably assumed to be designed to be 1 kHz. The round-trip bandwidth of PDAs and mobile phones is generally below 3 kHz. The transmission frequency is 0-10 kHz, even at 〇3 kHz bandwidth, which is impractical because it causes user confusion and because of poor SNR. In fact, many sonic noises exist every day in the lower frequencies covered by these bandwidths. On the other hand, the ultrasonic frequency starts at only 31 1298799 above 22 kHz, and therefore, in order to use the supersonic wave of the sound card electronic, frequency down conversion is preferable. 3 · Additional electronics require a power supply. As mentioned above, the microphone input can be used as a power source. In use, a set of charging channels can be multiplexed side by side with the signaling 5 channels to charge the base station 20. Additionally or differently, it may store the kinetic energy generated by the user's movement and convert the kinetic energy into electrical energy, thereby eliminating the need for the battery or extending the battery life. 4. Sampling frequency: Most of the Sound Blaster cards can be sampled at up to kHz, Nike 10 Sterling, and other sound cards have similar functions. Ships and mobile phones are sampled at a frequency of 6 kHz. The sampling rate provides a limit on the design of the system' which means that the synchronization signal transmitted from the pointing device needs to retain sufficient positioning data even at low sampling frequencies. The sharp "second" "lta" wave, which is commonly used by other positioning systems, is compatible with the available sampling rate. Preferably, substantially continuous signals are used. The preferred embodiment includes wireless communication between the pointing device 14 and the base station 20, which is connected to a computer microphone input. A simpler embodiment uses ^wired communication, which provides an electrical winding connection between the base station and the pointing device. This embodiment is particularly useful for "mouse" type fabrication, which requires relative positioning or 2" and is particularly simple and cost effective to manufacture. However, wired measures & are not suitable for many applications and therefore also require wireless measures. As described above, there are a number of conventional methods for determining the position of the pointing device. The conventional methods can be adapted to the embodiments of the present invention. In particular, the dedicated % way takes the conversion sensor output as a signal that can be fed into the 32 1298799 standard microphone wheel. Some preferred embodiments are described in detail below. Acoustic Localization A preferred embodiment uses acoustic localization. The sonic positioning concept is to measure the time difference between the two sets of signals arriving at the sensor array at different rates for a time difference of 5 to provide an indication of the distance to the sound source. If two different sets of perceptrons are used, triangulation can be used to determine the sound source location. If two sets of properly placed perceptrons are used, a three dimensional position is obtained. In a preferred embodiment, the two sets of signals are acoustic signals and IR or other electromagnetic signals. 10 The sound wave velocity at sea level is a set of conventional values. IR or other electromagnetic signals are advanced at the speed of light, and for this purpose the accuracy of the pointing device is considered to be instantaneous. A set of coordinates that release IR and sound signals is generated. The delay between the IR signal and the arrival of the two sets of form sound signals of the two sets of perceptrons is then measured. The two sets of delays are converted to distances and the distances are triangulated using the distance between known microphones to produce one-dimensional coordinates. The third set of microphones can receive a set of third form of sound signals such that a set of third delays can be used to add a set of third coordinates. The proper placement of the microphone provides a precise set of three-dimensional coordinates. In a further preferred embodiment, it is possible to replace the sensitizer and the IR signal with another set of mics. This results in greater calculations and reduced accuracy, but with a simpler device. The above embodiments are relatively straightforward and can be applied to some of the hardware provided in existing pointing devices. Indication Mounting 33 1298799 Referring next to Figure 2, there is shown a simplified diagram of a set of positioning elements suitable for use in the acoustic wave positioning embodiment described above. Positioning element 14 is indicative of the skirting pattern and includes a set of miniature loudspeakers 26 that act as a set of transducers to generate sound from electrical signals. Preferably, the loudspeaker is optimized for use in the wavelength of the ultrasonic wave. Additionally, a set of LEDs 28 can be provided to emit a second signal that is substantially instantaneous. Instead of an LED, an antenna can be used to transmit other RF signals at the appropriate frequency.

Control logic 30 is preferably fabricated using a microprocessor and provides coordination between amplifier 26 and LEDs 28, and provides a set of signal combinations from which a meaningful delay can be determined. Control logic can provide additional control functions if deemed necessary. Battery 32 provides power to indicator device 14. In another embodiment, the battery can be replaced by an induction coil that is powered by the base station using induction. This option saves the need for battery replacement in the pointing device, but limits its scope and adds complexity to the base station.

A set of switches 34 can be selectively provided. The switch can be provided for use in any range of functions, or can simply provide a signal that is determined by the operating system for its purpose or the application of the last transmitted signal. For example, the switch can be used to change the color of the line on the computer screen, or to replace the mouse button, or for shooting in a game, or to indicate contact with the screen: touch. In the latter case, the switch can be designed to be close to

Inter-contact. Hardware and Perceptron of K Referring next to Figure 3A, a simplified diagram of the internal components of the base station suitable for use with the indicator device of Figure 2, 34 1298799, is shown. Preferably, the base station includes an array of at least two sets of microphones 36 and 38 to obtain signals from the loudspeaker 26. It should be understood that the microphone acts like a transducer that converts the sound back to an electrical signal. In addition, the IR photodiode 40 detects the IR signal from the LED 28. In one variation, the 5 antenna can replace the IR photodiode, as explained above. Preamplifier and filter circuit 42 is preferably provided to each of transceptors 36, 38 and 40. The time or frequency multiplexing function 44 allows signals to be multiplexed onto a single channel. The frequency down conversion and mixer function 45 allows the received signal to be downconverted to a frequency compatible with the analog input being used. 10 Microprocessor 46 or other control logic is used to control and determine the base station coordinates. Synchronizing data allows the microprocessor to synchronize the signal components. Cables and sockets 48 are provided to connect to the microphone jack of the computing device' or any other input having an A/D converter. The data entering the analog input is preferably buffered and filtered by the buffer and filter circuit 49. Buffering can vary depending on whether the microphone jack or some other input is being used. The power supply circuit 50 allows the microphone jack to be used simultaneously as a power source for the base station and data output. There is an inherent synchronization problem when using the host CPU to decode the location data 20 that is transmitted from the analog input. The positioning component, i.e., the pointing device or the wireless terminal, is not synchronized with the base station, and then is not synchronized with the A/D of the host I. Synchronization of the wireless terminal and the base station can be accomplished using IR or RF signals, as explained herein. Synchronization along the line and host time base is not possible in many cases. Even with a relatively high 35 ^98799 ^ thousand 'eg 50 kHz, the mismatch 33 between the IR sync signal and the A/D sample can be within 2 〇 microseconds, which corresponds to a few of the measured bits. Centimeters. This accuracy is not suitable for most applications. Furthermore, even in the case of good synchronization in the 竿~κ "gas system, the two systems, ie the master and the base station,' the clock tends to be in time due to the accuracy of the existing crystal technology. In order to overcome the above problem of host synchronization, the base station preferably uses a certain sequence or frequency slot to transmit a synchronization sample of the host a/d converter Nyquist rate to the host. The host can use This pattern determines the phase difference between its own pulse and the positioning time base. The synchronization pattern can be transmitted to compensate for the drift of the clock, and the signal is transmitted every cycle. In a further preferred embodiment, the base station circuit transmits commands to the positioning device 'whether using acoustic, optical, infrared, RF or any other type of signal' as long as the indicating device is capable of responding sensitively thereto. In this consistent embodiment, the positioning element 14 has an RF or optical receiver. When receiving the command, the pointing device can transmit a signal, for example, the acoustic signal discussed above. Transmission time is known, and may be used to delay the acoustic signal has been received at the beginning of the leaf in the different acoustic microphone 20 ^ respectively delay number again may be used to reach the positioning coordinates.

The base station of the embodiment of Figure 1B is shown in Figure 3B. The same reference numerals are given to the same parts as in Fig. 3A and no explanation is given except for the necessary limits for graphical understanding. In Fig. 3B, the a/D conversion state 55 takes the output of the down conversion section 45 and supplies it to the cpu 56. The CPU 36 1298799 56 is connected to the memory 57 and the digital material. The cpu completes the waveform decoding to determine the position of the clamp element 14 and additionally can perform the application using the determined localization poor therefore. This feature is preferably provided within the base station wafer set. This measure therefore results in a more complex and more expensive base 5 platform than Figure 3A. However, the circuit can be used exclusively for the signal-to-seat described below as "decoding broadly, and thus comparing currently available measures, which are still relatively simple. Eight/decoded submagnetism is preferably provided for conversion. The digitization of the indication device signal is converted into a local coordinate system or directly to the attendant. The method is preferably provided as a client device of the computing device or a built-in local operating system. The driver or in particular is part of a specific application. In the embodiment of the invention, the algorithm can be incorporated into the base station electronic circuit. 15 The method of rotation is preferably the relative _ sampling of the green Frequency function. This conversion reduces the data frequency from the relative two frequencies required by the transmission positioning component to the relatively low frequency at which the installed sound hardware is likely to be sampled and digitized. Furthermore, the algorithm preferably includes processing noise. The ability and, preferably, is a specific argument for low-frequency signal processing. As mentioned above, the conventional technology of the position-positioning field towel is very short-lived. And a strong acoustic signal as a positioning signal. In order to achieve a good resolution 'preferred measures require a high sampling frequency, generally higher than 働 kHz' in order to be able to find such a short positioning signal and not completely miss it 37 1298799 Relatively, the 'perfect application' is preferably not to use a sampling rate higher than 1 kHz, because this frequency is not compatible with the installation basis of the sound processing equipment. Further, the age is maintained higher than 2 〇 kHz's beacon signal sound frequency, which is within the ultrasonic range, so the user can't hear it. The two needs 5 10 15 20 need - group measures, material (four) is Xia in the ultrasonic signal or waveform / The data can be frequency modulated on top of the carrier containing the ultrasonic signal (TM is phased), or the other known table can be manipulated to decode the modulated signal and From the sampled junction, the signal with the original positioning information is reconstructed. In this embodiment, it is preferable to use a signal of a limited frequency band to achieve the required resolution level. Preferably, the continuous waveform (CW) modulation , for example, exhibition And frequency hopping is used for acoustic mosquitoes, with disparity reflections and township effects. General's more than-group detectors are used, and the detectors are "multipleed for single-transmission" In some cases, it can be avoided. For example, in the case of a stereo input card or a stereo effect card, the group can feed two sets of signals into the microphone input, and another ^ The two sets of signals are sent to the line, and the input is made so that all the four _ numbers do not need to be multi-guarded together. Therefore, the base station does not need a time-sharing multiplexer for input access. The group perceptron can be fed directly to the sound card, and then the internal circuitry of the sound card can be used to "process the received signal using the appropriate software driver. However, it should be noted that even stereo input sound card has up to two sets of A/D conversion. Therefore, it is still necessary to perform time-division multiplexing to complete sampling on more than two channels in two or two channels. 5 only

In order for the stereo input sound card to be sampled on the two 38 1298799 channels on the two sets of A/D conversion, the transmitted signals can therefore be synchronized with each other using the base station. This synchronization can be achieved in some way. One way is to transmit synchronized data from or to the base station side by side with the signal. Another method requires cyclic transmission, i.e., the signals are transmitted in a coordinated manner, so that signal periods or phases between the known channels on both sides are used. The previously described method requires the organization to provide data synchronization when needed and when no internal parts are needed. The other uses of the above-described respective stereo inputs have certain disadvantages compared to other embodiments which are not prioritized by delta. Thus, for example, there may be a phase difference between the samples taken by each of the two sets of A/d converters, and therefore the uranium-weighted positive step in the use of the system must be achieved. Otherwise, the phase difference itself may be confused by the distance determination, resulting in reduced accuracy. Another disadvantage is that relatively complex software drive functions are required to keep the switching timing between the microphone input and the "incoming line" input as accurate as possible. - At room temperature, only slightly between switching timings The jitter state of the second can lead to an incorrect measurement of 33mm. In addition, many installed sound card bases only allow mono input. Very few sound cards are equipped for stereo microphone input. With additional inputs, the base station must provide additional connectors and wiring, which is not possible for most users, so additional costs may be added. The preferred embodiment of the present invention uses - group maximum likelihood detection The decoder determines the distance to the respective perceptrons by decoding the signals received from the perceptron. The signals received from the perceptron via the base station are compared to the reference signal using the maximum likelihood detection benefit. The comparison indicates the most likely The signal is 39 1298799 and the signal is most likely to be transmitted from the distance using the most probable signal. Preferably, the most The large likelihood detector uses a full mathematical mode 5 10 15 to form a look-up table for comparing the reference signals of the received signals, so that the best matching distance can be found. In addition, the expected dimming, ^, and month The waveform can be sampled at the Nyquist rate, and the timing at the sampling point can be overcome using an extrapolation function to reveal any distance that is not matched by the method. Next, refer to Figure 4, which is A set of simplified block diagrams indicating the mathematical mode components of a set of maximum likelihood detectors considered above B. Mode 6 〇 contains a set of start signal sequences S (t) that are fed into the moving parts The transfer function H1(s) of the unit 丨4^2nd slave 26. The gas gap 62 is immediately after the activity's it is simply patterned with a delay. The gas gap is changed for different distances. Then it is fed to the receiving pass in the base (4), , :, the transfer function of the 匕a 克 风 wind 36 is called 4, the equalizer is out (., and (4) filtering, wave H4(s) and mixing, and any other channel Features. The full nuclear type of the channel is the most likely The design of the detector is useful in that it allows a precisely expected signal to be constructed, while the received signal is ideally only phase 5 nuclear gains, and then relatively easy to identify the most probable signal, which sequentially corresponds to the most Possible distance. The signal is used in the maximum probability of the main mechanism, starting with the set delay of 3 and at the same time also the clock between the active part unit and the base station. The synchronization channel 64 is indicated on this mode. Specifically, the channel provides a set of synchronization signals to the local oscillator. ', the driver will understand that the acoustic signal has a different angle transfer 20 1298799 (two) number. The equalizer can be added to the base station to compensate This fact is preferred. The IR (or other electromagnetic) signal also indicates that the second channel 66 is equivalent to the start time of the zero distance in the distance table 68. The most likely signal obtained using the maximum likelihood detector is then used 5 to identify a set of most likely non-zero distances from the look-up table. Those skilled in the art will appreciate that it is possible to replace the look-up table with an array produced in real time. More progressively, other detectors can be used; and there are many conventional FM signal decoders such as PLL, I/Q demodulation, phase multiplication, and the like. The maximum likelihood distance can then be tested using correlation, and briefly reference is made to Figure 5, which is a graph showing two parts of a general correlation function that can be used. The top of the graph shows its function, and the lower part of the graph is a magnified or zoomed-in view of the center of the top of the graph. Referring next to Figure 6, a simplified block diagram showing a decoding unit 70 for performing the above decoding. The decoding unit 7A includes a set of maximum likelihood detectors 72 using the channel pattern 60 described with reference to the above-mentioned FIG. 4, and a look-up table 68. Immediately following the maximum likelihood detector 72, the correlator 74 uses the correlation function 76 to use the most probable distance detected by the maximum likelihood detector 72 to perform its correlation calculation to confirm whether the detection distance is correct. Referring next to Figure 7, a simplified diagram of a pointing device in accordance with a further preferred embodiment of the present invention is shown. The same reference numerals are given to the same parts as the previous figures and will not be described except for the necessary limits for graphical understanding. The pointing device of Fig. 7 is different from Fig. 2, which additionally comprises a coding unit 80 connected between the LED 28 and the loudspeaker 26. The encoding unit 80 provides additional signal encoding prior to output to the loudspeaker 26. In addition, the signal encoding of 1298799 can be used for greater signal robustness while also minimizing interference with nearby users. The latter has many benefits. It allows a large number of users to use the same base station, or can allow a single user to use many pointing devices, for example, in a chess game. If each game component is a different set of pointing devices and signal decoding allows the different pointing device to be recognized, the system can include games for a plurality of gaming components. Keeping the dry (4) with the neighboring users to the minimum allows the majority of users to coexist in the same room. One of the preferred ways to minimize interference between different pointing devices is to use a false random hopping algorithm. Preferably, each of the active component units has a pseudo-random random hopping sequence that is fitted within coding unit 80, or is within controller 30. Preferably, the base station or decoding unit has a -group corresponding de-hopping unit that can be synchronized over the same hopping sequence. The preferred embodiment provides synchronization by using IR or other electromagnetic signals to pass the sequence to the base station. Another preferred embodiment uses factory calibration to provide a set of sequences. An application that can be implemented according to the frequency hopping detection system is the integration of the system base station 2G and the WLAN base station. It leads to -_ strong 20

The user _ makes (4) on or compatible with the pointing device and writes on the paper or writes on the electronic thin that he touches. form. For the purpose of writing on paper, the instruction: Set the combination of the indicating device and the standard material of the brother 2B. < 42 1298799 Customers and applications need to be diverse, and separate applications may need to maximize specific variables associated with each other. For example, in an application, accuracy may be less important than current consumption, and thus the number of possible levels of accuracy or positive operation may be reduced to help reduce current consumption. In order to allow optimization of this particular system without having to manufacture a series of similar devices, a flexible planable mechanism is preferred for the base station and the moving parts unit. Elasticity planning can be achieved using blown fuses or by the use of non-electrical memories such as ROM or EEPROM. The 10 general data set in this way include: sample rate per second, transmit power, 2-D or 3-D applications, and the like. The positioning element 14 can additionally be supplied with a set of pressure sensors whose outputs can be used in appropriate applications that allow for graphics or security features. For example, the line can be drawn differently depending on the pressure applied. A suitable pressure sensor incorporated into the indication can include a set of digitizers (10 bits or less), a set of strain gauges, and a set of drive circuits. Another feature can include the ability to measure the angle of a moving component unit (useful for examples of digitally drawn needle applications). A suitable angle sensor incorporating the indicator device 14 can include a set of tilt measuring instruments, digitizers, and drive circuits. In a further embodiment, two sets of positioning indicators, such as a super-chopper loudspeaker, can be placed at either end of the pointing device, each of which produces a discernible signal in the form of 1298799. ^ v . . . wheel. The angle of the pointing device can then be derived using the different geometries and simple geometrics between them. Independent Base Station As mentioned above, in Figure 5 10, the base station 20 contains the ability to decode signals without the support of the host 铪 戍 戍 戽 戽 置. The decoding described here, and / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / /

The cost of the project is in the best case, and the computing power of one of the Jolland PS is decoded. This set of computing capabilities can in fact be integrated into a single-custom base wafer or as a low-end one. This use of the CPU allows for a more connected connection to the host, such as: UART, USB, serial port, and others, because the transmitted signal is the result of the positioning process rather than the unprocessed signal. This output is also suitable for direct use within WLAN and Bluetooth. Preferably, the standalone base station includes a set of digital components, (A/D converters), a set of CPUs, a set of memory, and interface circuitry.

Light Positioning Referring next to Figure 8, a simplified block diagram showing the above-described variations in the use of light to the discovery sensor. The same parts as the previous figures are given the same reference numerals and will not be described except for the limits necessary to understand the figure. The sensor 90 includes two sets of LEDs 92 and 94 that are offset by a predetermined angle. Differential amplifier 96 is coupled between the two sets of LEDs 92 and 94 via groups of its two sets of differential inputs to measure the difference between the current levels of the two sets of LEDs. The LEDs 28 in the pointing device 14 produce a set of 44 1298799 narrow beams whose direction can be measured from the sensor. The sensor 90 is preferably constructed using optical lenses in the lenses 98 and 100 to cover the sensing area and to ensure that light from a predetermined range of field of view falls directly down to the sensing area. The base station is essentially the same as Figure 3, in which the light direction discovery sensor 90 is used in place of the microphone and does not require separate IR light diodes, since all of its synchronization and similar functions can be detected by the light direction sensor. Replaced by light diodes. The corresponding decoding algorithm processes different types of signal information portions, but the basic poor information is processed in roughly the same way. The principle of finding direction and distance is similar to stereo vision and the angles of the two sets of perceptrons are found and triangulated to obtain a position. In addition to this, the same argument applies to the decoding algorithm of the previous embodiment, i.e., if the system utilizes analog input and computational device hardware, a low sampling rate and low frequency are required. 15 Morphology Detection 20 Referring next to Figure 9, a simplified diagram showing a second embodiment of a shape suitable for morphological detection. The same part of the figure is given the same reference number and is removed from the limit of the _ necessary limit. No more money is given. ♦ month: the loudspeaker 26' is provided to leave the first loudspeaker 26_ Pre-determined distance: Two sets of loudspeakers are provided at the opposite ends of the component. Each of the sound amplifications is determined by the respective waveforms 'which are respectively detected and the component shape is favorable - enough to draw a straight line. Preferably, the two sets of loudspeakers recognize themselves and operate simultaneously. Their eight other money can be acted upon by time or frequency, and in the preferred embodiment, the frequency hopping. Two sets of loudspeakers use different pseudo random sequences for gravity and magnetic positioning

The plate of the magnetic circuit (conductor) arranged orthogonally right is used as a writing board to emit an electromagnetic signal, which is recorded by the magnetic circuit of the writing board, and the signal of the indicating device can be Calculate. The measured use of the ^® 5 circuit can be printed on the required precision PCB and can be constructed to be small enough to produce any

The indicating device is harmonized with Figure 2, except that the coffee maker 28 is replaced by an electromagnetic transmitter comprising a set of transmitting antennas and associated modulation circuits. The base station contains a built-in loop as a perceptron with a good demodulation circuit, otherwise it is the same as the base station of Figure 3. Except that the m-method must deal with different types of signal information, it covers the same arguments as described above.

The positioning system of this embodiment has a wide range of applications, some of which are listed below. Preferably, a single set of electronic devices is fabricated and the month b is set differently for use by the selected application by using jumper or double throw switches. This switch allows the system to be configured for the most appropriate compromise for the application. In some applications, low power consumption is important. In addition, the positioning accuracy is also dominant. In addition, the accuracy is less important than the rapid update and the number of samples per second. The scope of the other is important, and for others, the ability to accommodate a large number of users may be primary. 46 1298799 Below, some of the techniques described above are considered. Global Tracking System Next, refer to Figure ί, which is a simplified diagram showing a conference room with a global tracking system. The global tracking system includes a wireless LAN system 110 having a buried 5 base station in accordance with the present embodiment. According to a preferred embodiment, a series of users 112 in the conference room have positioning elements 114. Each locating element has its own unique identity as described above. Various positioning elements emit waveforms and the waveforms are detected by the global tracking system. Alternatively, the waveform can be tracked by a user's local tracking system, e.g., a standalone base station 116, a portable telephone 118 having a built-in base station, and the like. In addition, the conference table itself may have its own primary base station 120 combined with the conference room telephone equipment.
