Patent ID: 8204601

Claim:
A cranial electrostimulation apparatus comprising a power supply configured to generate a DC power signal wherein said power supply is a battery; a signal generator configured to generate a control signal for modulating said power signal corresponding to a waveform adapted to provide therapeutic value to a patient; a voltage regulator coupled to receive said DC power signal from said power supply and output a regulated DC voltage signal; wherein said voltage regulator maintains said regulated DC voltage within a predetermined range as said DC power signal changes over the useful service duration of said power supply; a line driver configured to receive as inputs said control signal and said regulated DC voltage signal and generate an output waveform signal by modulating said regulated DC power signal with the control signal; electrodes coupled to receive said output waveform signal; and wherein said control signal is adapted to encode a therapeutic protocol for one of treatment and prevention of symptoms of withdrawal from one or more addictive substances.
