Device for reducing power consumption in medical equipment which is implantable in the human body
First Claim
1. A device for reducing power consumption in medical electrical equipment implantable in the human body, said device comprising:
- sensor means, including a sensor element connected to sensor electronic circuitry, for sensing a parameter for use in the in vivo control of the operation of said medical electrical equipment, said sensor electronic circuitry being operable in a passive mode with low power consumption and an active mode with a higher power consumption;
said sensor electronic circuitry including a power supply unit; and
comparator means, having an output connected to said power supply unit, for comparing an output signal from said sensor element to a predetermined threshold and for controlling said power supply unit to switch said sensor electronic circuitry between said passive mode and said active mode dependent on the magnitude of said output signal of said sensor element in relation to said threshold.

Abstract
A device for reducing power consumption in medical electrical equipment, implantable in the human body, having a sensor, which includes a sensor element and sensor electronic circuitry for sensing a parameter relevant to control of the equipment'"'"'s in vivo operation, also has a comparator which compares the sensor element'"'"'s output signal to a predesignated threshold value and switches the sensor electronic circuitry from a passive mode with low power consumption to an active mode with heavier power consumption or vice-versa, depending on the magnitude of the sensor element'"'"'s signal in relation to the threshold value.
