Abstract:
1. An electronic biosensor, comprising: a housing configured for hand-held manipulation by a clinician relative to a patient; a transducer supported by the housing and configured to sense a manifestation of acoustic energy produced by matter of biological origin; an output device configured to output a signal comprising signal information produced by the transducer; a processor disposed in the housing; a sensor; and power management circuitry disposed in the housing and coupled to the processor and the sensor, the power management circuitry comprising detection circuitry configured to detect a plurality of features of a signal produced by the sensor, the plurality of features including at least one parameter of the clinician, the power management circuitry implementing conditional power management logic by which the power management circuitry discriminates between intended use and unintended use of the biosensor by the clinician, wherein the sensor is configured to sense a parameter indicative of sensor contact or proximity between the housing and a hand or fingers of the clinician, wherein the sensor is configured to sense at least one of temperature, capacitance, impedance, pressure, force and acceleration, the power management circuitry and the processor cooperating to control power supplied to biosensor components based on the plurality of sensor signal features.
