Title: Discriminating device
Inventor: SHIBATA CHOKICHIRO
IPC: G01V3/12
Filed: 1985-03-04
Abstract: PURPOSE:To prolong the service life of a battery by arranging so that the power source of the discriminating device is turned on when the photodetecting element of the device receives the rays of light from a light source. CONSTITUTION:When a monitor light source 1 emits light, a photo-voltaic element 2 receives this light to produce an electromotive force, thereby the current energizes a relay 3. Thus the current is applied to an oscillating and code modulating circuit 4 to initiates the circuit 4. by the operation of the circuit 4, the signals of a constant frequency are generated and modulated by the discriminating coding signals. The code modulated output of the circuit 4 is emitted from the transmitting antenna 6 of the device 9 and received by a receiver 8 through the antenna 7 of the receiver. At the receiver 8, the received signals are demodulated and the codes are decoded to execute the discrimination of the device 9. In such a manner, the service life of the battery is prolonged.
