Abstract
An electrical body stimulator having particular utility for transcutaneous electronic nerve stimulation. Circuitry is provided which delivers a driving pulse, the stimulator output circuitry being responsive to the driving pulse duration for establishing at least one stimulation signal parameter in accordance therewith. In a preferred embodiment, the driving pulse generator includes an energy storage device and an oscillating power supply connected to the storage device for alternately charging and discharging the storage device. A dual state device responds to the charge level of the energy storage device and changes state in response to predetermined changes in the energy storage device charge level. The charging rate is alterable to alter the duration of the driving pulse.
