AN ECONOMY IN POWER CONSUMPTION SENSOR CIRCUIT OF A VERTEBRA CURVE-SYMPTOM CORRECTION APPOINTMENT SURVEILLANCE DEVICE

摘要: A power saving sensor circuit of a for scoliosis correcting support is provided to improve the life span battery by supplying pressure detecting only if necessary. circuit(101) includes control unit(300) applying unit(302) an input unit(301) when command applied from microprocessor(200) resistance(R1) obtain information about sensor(401) and unit(400) stably sensing result against noise. The unit comprises coupling unit(303) making apply conducting first transistor(Q1) resistance recognition unit(304) indicating that capacitor(C1).
