Patent ID: 7904150

Claim:
A biofeedback electronic stimulation device comprising: a user interface for providing at least one input signal; a processor for generating a first control signal and a plurality of second control signals responsive to the at least one input signal; a pulse generator circuit for generating a charge current responsive to the first control signal; a transformer for generating a stimulation signal including packets of at least one pulse responsive to the charge current; damping circuitry for configuring the at least one pulse in the packets to a selected one of a plurality of configurations responsive to the plurality of second control signals; output electrodes for applying the stimulation signal to a user; detector circuitry for detecting zero crossings of the at least one pulse in the packet of the stimulation signal; an audio indicator for providing an audio indication to cease application of the stimulation signal responsive to a third control signal from the processor; a visual indicator for providing a visual indication of at least one mode of operation of the device responsive to the at least one input signal; wherein the processor further causes generation of an indicator responsive to the detected zero crossings; and wherein the processor further configures a spacing between the packets of the stimulation signal, a number of pulses in the packets of the stimulation signal, a spacing between the pulses in the packets of the stimulation signal, and a damping of the pulses in the packets of the stimulation signal.
