摘要： A proximity sensor (1) includes a state updating section (22) and a control section (5). The state updating section (22) updates state information. In a case where the state information is updated with a state (ST1) or a state (ST4), the control section (5) supplies, to the outside of the proximity sensor (1), a signal (S6) indicating that at an object (B) to be detected does not come close to the proximity sensor (1). In a case where the state information is updated with a state (ST2) or a state (ST3), the control section (5) supplies, to the outside of the proximity sensor (1), a signal (S6) indicating that the object (B) to be detected comes close to the proximity sensor (1).

摘要： An optical modulation-type detection device has a noise detection mode having (i) an offset canceling (hereinafter referred to as “OC”) period in which (a) the light-reception signal pathway of a pulse signal converting section is cut off so that an offset of the pulse signal converting section is suppressed and (b) the light-reception signal pathway of the pulse signal converting section is reconnected while a state in which the offset is suppressed is being maintained, at an end of the OC period, and (ii) an asynchronous reception period in which whether or not asynchronous reception occurs is detected after the first period, and an object detection mode having a synchronous reception period in which whether or not synchronous reception occurs is detected after the asynchronous reception is not detected in the noise detection mode.

摘要： An abnormal pulse detection circuit in a receiver of the present invention includes: an incoming pulse edge detection circuit which detects the moment of rise of an input signal and outputs the result of the detection as an edge detection signal; a muting reference pulse generation circuit which generates a muting reference pulse based on the edge detection signal; a logic circuit which outputs a signal indicating a negative AND of the muting reference pulse and the input signal; a muting signal generation circuit which generates a muting signal from the output signal of the logic circuit; and a switching circuit which outputs the input signal or the muting signal. The receiver of the present invention can therefore reduce discomfort in hearing reproduced sound in case where a noise occurs in an audio signal due to a variation in pulse width.
