Abstract:
An electro-therapeutic stimulator provides an output signal having a first controllable main pulse periodic-exponential signal and a second background pulse periodic-exponential signal. The main pulse signal is controllable, preferably to a digital numerical value of 1 to 500 pulses per second, to a digital, numerical value of duty cycle, and to a digital numerical value of balance. The signal is produced using a class D amplifier and with a transformer optimized for the background pulse (such as at 10 kHz) rather than for the main pulse. The electro-therapeutic stimulator includes a counter which forces purchasing of durations of signal time for ongoing use of the stimulator, and a challenge code procedure for facilitating additional time purchases.
