This initiates a start sequence which sets up the system for external communication. If desired, the user may exit at this time by clicking the button. The microcontroller then waits to receive a message via the I 2 C bus. A message is received, the microcontroller determines whether the address that the external device desires to access is valid. If so, the microcontroller determines whether the request is to read or write to the system memory. The microcontroller may be programmed to prevent read or write access to certain portions of the memory. Accordingly, the microcontroller determines whether a read or write is permissible, and if so, performs the read or write function.
  • the microcontroller software preferably provides a menu system which provides a link between all the hardware services within the system and the user services for reception, display and dialogue of information. It also provides for various modes of operation and for running interface protocols to communicate with the LCD display and I 2 C interface.

  • microcontroller 30 When the unit is turned on, microcontroller 30 will perform a self-test and then automatically enter the menu system. The microcontroller 30 will generally wait in the "STOP" mode until a user input is received. The menu system will then display an option which the user may either select with a double click on button 26 or pass over with a single click on button 26. Selecting an option will cause one of the following to occur: either another menu will be entered to provide options within the newly selected category or an action is performed, i.e., a number is dialed out. A flow diagram showing operation of the menu system is shown in FIG. 8. The menu system is preferably implemented as a stack which is contained in memory and enables the size of the system software or firmware to be minimized.
  • previous menus are pushed on to the stack.
  • previous menus are popped from the stack.
  • options which are to perform functions may be stored in the stack as well.
  • a first button push dials out the long-distance access number, a second push sends the calling card number and third push dials the number received by the pager. If a local call is received then a first push dials the received number with a '0' or other prefix and a second push dials the calling card number.
  • FIG. 9 shows a flow diagram of the system operation for receiving a page.
  • the paging system generates a paging interrupt to the microcontroller which reads the paging message to memory. If time stamp mode is enabled, the message is saved along with the time stamp from the real-time click. If the user alert mode is enable, a tone is generated by means of the DTMF tone generator. Finally, if an auto-dial-out option is enabled, the message will be pushed onto the menu stack. In this mode, if the user selects the message via the menu system and clicks on the message, the telephone number of the message will be automatically dialed out.
  • the stack-based menu system can be used to carry out personal information functions in addition to simply traversing menus.
  • Calendar events are detected by the real-time clock and the user is beeped automatically at a preset time. This automatically causes the menu system to enter the calendar menu so that the user need only double click to select the timed event and see the displayed message.
  • FIG. 10 shows a flow diagram for operation of the scheduling system on the pen. The system operates in a loop comparing schedule times to the current time. When a match occurs, the user is alerted, if this mode is selected. Finally, if the auto-mode is selected, the scheduled event may be pushed onto the stack along with an associated function. When this entry is selected from the menu system, the desired function will be carried out.
  • Collisions can occur between functions in the pen. For example, a calendar event may occur and beep the user at the same time that a page is received and also beeps the user. When this occurs, the system stacks up the events and indicates to the user that the stack has multiple entries on it by changing the display so that, for example, it flashes. It is readily foreseen that the menu system of the invention may be modified in many respects while keeping within the scope of the invention.
  • the present invention may include one of several security mechanisms to prevent misuse of the system.
  • a password protection scheme can be in force that only permits access to the pen's information if a password is entered correctly.
  • the password is entered via the menu system by selecting a series of characters and numbers. For example, the user may scroll through the character set with each click of button 26 or if the button is held down the cursor will scroll automatically. Once the correct character is found, the user may double-click to move to the next character of the password.
  • a five or six character password can thus be readily entered into the pen and provide, with a 40 character set, over 4 billion combinations.
  • the password, if enabled is entered every time the pen is powered-up and remains in force as long as the pen is active. It may be desired that only the telephone directory or other system function be protected in which case the password need only be entered when that menu is entered.
  • microcontroller 30 When a page is addressed to an address reserved for disabling the system, all pen functions may be terminated by microcontroller 30.
  • Micro ⁇ controller 30 preferably contains an on-board memory which is not accessible via the I 2 C bus (which might otherwise enable the security feature to be bypassed via the inkwell) .
  • the microcontroller makes a non-volatile memory entry which prevents use of any of the system functions until the system is re-enabled from the paging transmitter.
  • This security system can be used if the pen is reported lost or stolen and will prevent calling card misuse and also prevent access to the stored information.
  • Another page, using either the same security address or another address reserved for enabling the pen can be sent to re- enable the pen.
  • microcontroller 30 can delete the memory entry which kept it disabled.
  • the enable/disable mechanism is linked only to the paging receiver and cannot be overridden by the user.
  • a second level of security may be offered, as shown in FIG. 11.
  • a security page would transmit a message for turning on or off the pager.
  • the message would also include a key message, and a new key. If the transmitted key matches the key stored in the system memory, the pen would turn on or off as instructed, and the new key would operate as the key for the next enable/disable operation. If the key did not match, no operation would occur.
  • This mode reduces the likelihood the possibility of bypassing the system security by determining the key.
  • Another level of security can also be offered whereby the pen can be sent a security page requiring the user to enter a password in response to an action performed by the pen. This could be, for example, if the user's telephone calling card access is beyond the user's normal profile, or if the pen is being used to access a banking system at a high security level, a password could be required from the user. These functions preferably do not require complex overhead within the pen. Rather, the pen is simply being used to dial out a number or series of numbers. The receiving system determines that further security is required and sends a special page to the pen. The password is then entered by the user and the system carries on.
  • the pen can only be reactivated by a security page or by entering a full system password. Both security system can be used separately or in combination to protect the user information and to prevent credit fraud through unauthorized use of calling card numbers.
  • the circuit board 20 which carries all of the electronic components of the system is preferably mounted between speaker 24 and batteries 22.
  • Circuit board 20 is manufactured using flexible manufacturing techniques which enable all of the components to fit within the pen.
  • Rigid lands are provided upon which the electronic circuit boards are mounted. The lands are joined together by a flexible circuit so that the entire assembly can be folded-up into a 3-dimensional volume as opposed to a more traditional 2-D circuit board.
  • the circuit connections between the circuit boards on the lands are made with conductive polymer inks that are printed onto the surface of a flexible material such as Kevlar.
  • the inks are then cured and the rigid lands are laminated to the flexible material.
  • the bare IC dies are then attached to the circuit board via wire bonding. If desired, the IC dies may be mounted face down onto the circuit before the inks are cured and the dies may be attached directly to the circuit as part of the curing process.
