Abstract: A device for the electrostimulation therapy of a type having at least one circuit with a pair of electrodes, a program memory and a control unit is provided with a microprocessor for producing desired curves and frequencies responsive to information and instructions from program memory and the control unit, an intermediate memory associated with the microprocessor for storing data in the form of instantaneous values representing the curves and frequencies, and address means for providing an output of the instantaneous values stored in the intermediate memory responsive to a demand from the microprocessor for information for providing a curve. The device can be adapted for electrical interference therapy such that the device has two separate circuits and two associated pair of electrodes. The adapted device has an intermediate memory, for storing instantaneous values, connected with each of the separate circuits.

Abstract: Apparatus and process for stimulating muscle such as where a portion of a muscle and its nerve structure are damaged. Muscle stimulators are embedded within the muscle at the general location where the muscle is to be activated. Muscle stimulation signals are transmitted to the muscle stimulators by a transmitter-receiver which receives muscle potential signals from muscle potential sensors embedded within the muscle, and converts these signals into muscle stimulation signals. The transmitter-receiver may be mounted on a cuff which can be externally secured. The cuff, the stimulators, and sensors are provided with antennas such that the transmitter-receiver transmits and receives signals without being wired to the sensors and stimulators. The sensors and stimulators have power supplies which may be energized from external high frequency sources which may themselves be mounted on the cuff. Power transmission occurs through antennas such that the sources need not be wired to the various components.

Abstract: A teaching aid for use with equipment having an instrument panel provided with at least one of operating elements and diagnostic instruments. The teaching aid includes one or more charts which are removable in a predetermined sequence in steps from the instrument panel. The charts located beneath a removed chart in an instruction step are provided with openings associated with the operating elements to be exposed for operation in a given teaching step. The charts located beneath a removed chart in a teaching step may also be provided with windows matching the diagnostic instruments to be exposed for reading in a given teaching step.
