  • FIG. 10 shows examples of each of the different patterns including, ramp 1000, burst 1002, short pulse 1004 and combination of ramp and burst 1006 that can be used to in these customisable pulse modes.

  • Bit 0 — A 1 indicate last pattern. Go to first pattern until time out.
  • the upper byte relates to short pulse the lower byte relates to pulse width up to 480 ⁇ s. A step of 32 ⁇ s in pulse width is used. Short pulses of up to 16 ⁇ s may be used for massage frequencies of less than 10 Hz.

  • An example mode may incorporate synchronising the electrical pulse output with the amplitude and/or frequency of an audio signal.
  • the system may simultaneously deliver therapeutic music and synchronised high voltage electrical pulses to the user.
  • the modes include music sync tap mode 314, music sync squeeze mode 316, Music sync chop mode 318 and Music sync mixed mode 320.
  • the music may be supplied by MP3 format audio stored on removable media.
  • the MU microcontroller 400 is connected to an MP3 player 418 and an equalizer sub unit 416.
  • the MP3 player 418 connects to the MU microcontroller 400 using a serial communication port 426 for example RS-232C.

  • Figure 12 shows an example of an equaliser subunit 416 that accepts a fixed level music output 432 from the MP3 player 418. It is necessary to have fixed level input so that the level of the high voltage electrical pulse is independent of the headphone level.

  • Each of the bandpass signals is passed through a peak detector to provide a DC signal indicative of the level of that band.

  • the reset signal 1220 will reset the multiplexer 1216 to output the first band, which is the 100Hz band 1204.
  • the MU controls the multiplexer to cycle through the DC levels of the 100Hz band 1204, 330Hz band 1206, 1kHz band 1208, 3.3kHz band 1210, & 10 kHz band 1212 every 0.5ms.
  • step 900M if Music sync mode is selected then the Set_Frequency_&_Amplitude command is transmitted to the selected TP in step 900N.
  • Figure 15 shows the process of determining the Set_Frequency_&_Amplitude command, according to an example firmware programmed in both the MU and TP microcontrollers.
  • An outer loop runs every 4s.
  • the outer loop includes step 1500 of determining the highest level of the 5 frequency bands over the preceding 4s period.
  • the massage pulse frequency is set based on the nominal frequency of the bandpass filter with the highest level output ("the predominant frequency").
  • the frequency command is determined based on the user selected massage mode (eg: music sync tap mode, music sync chop mode & music sync squeeze mode), the translation strategy relating to that user selected massage mode and the predominant frequency during the last 4s.
  • An inner loop runs at an interval of 25 ms.
  • the amplitude of the selected frequency band is measured every 0.5ms.
  • the amplitude of the command is based on the output DC level or amplitude of the selected bandpass filter over the 25ms period.
  • the predominant frequency is translated into the massaging frequency.
  • the massage pulse frequency ranges from 1 to 200 Hz.
  • a different translation strategy will apply. For example in music sync tap mode the translation results in pulse frequencies between 1 to 10Hz. In music sync chop mode the translation results in pulse frequencies between 10 to 35Hz. In music sync squeeze mode the translation results in pulse frequencies above 35Hz. For example where the music sync chop mode is selected an example translation strategy is shown below:
  • This translation of the predominant frequency to a resulting applied pulse of between 25Hz to 35Hz will result in a chopping sensation on human body.
  • the applied pulse will have a frequency of 35Hz and will vary in amplitude depending on the DC output level of the 10kHz band pass filter. It is possible to translate the 100Hz band to a tapping frequency such that when a heavy bass music is being played; a tapping sensation is experienced. However; a delay in synchronisation may be felt when pulse frequency below 15Hz is used.
  • the music can affect the massage pulse. For example if the music level is below a lower threshold the massage pulse defaults to the lowest intensity setting. If the music level is above an upper threshold for more than 3s, the massage pulse is paused for 0.1s to 0.2s.
