摘要： A transmitter portion 14 includes a control circuit 32, a driver circuit 33, and a wave detector circuit 35. The control circuit 32 generates control signals Vp, Vn based on a pulsed transmission signal So. The driver circuit 33, which is supplied with a battery voltage Vb, generates an output signal Sa to be sent to an antenna 13 based on the control signals Vp, Vn. The wave detector circuit 35 outputs a detection signal Sk having a voltage proportional to the level of the output signal Sa (transmission power level). The control circuit 32 changes the pulse widths of the control signals Vp, Vn based on the voltage level of the detection signal Sk. As a result, electric power consumption is reduced and enlargement of an apparatus is suppressed while maintaining the transmission power level constant.

摘要： A capacitance change detection device includes a sensor electrode, and an electrode capacitance measurement device for measuring capacitance of the sensor electrode on the basis of a correlation value based on a reference capacitance at every first predetermined time. A detection signal is generated when a current measurement value of capacitance is changed by equal to or greater predetermined threshold value than a measurement value obtained a second predetermined time before the current measurement value is measured. The capacitance change detection device further includes a sensitivity compensation capacitance for generating capacitance variations equivalent to specific variations of capacitance of the sensor electrode, and being switched between a connected state and a disconnected state. The threshold value is determined as a difference between measurement values of capacitance of the sensor electrode measured at the connected state and at the disconnected state. The threshold value is renewed at every third predetermined time.
