ABSTRACT:
Power consumption in medical and battery powered devices is reduced through the use and operation of a data monitor which measures, senses or detects signals, inputs or outputs in a medical device before they are input to a principal or main digital signal processor, controller or microprocessor. In response to detecting or measuring such a signal which meets certain amplitude, frequency and/or phase characteristics, the data monitor directs or controls clock or voltage supply circuits to increase or decrease clock frequency, or to increase or decrease the voltage provided to certain circuits within the medical device. The clock frequencies and/or voltages so employed are tailored to reduce the amount of power consumed by the medical device while preserving computational performance.
