DETECTOR FOR DISASTER VICTIM AND DETECTION SYSTEM FOR MISSING PERSON AT DISASTER TIME

摘要

PROBLEM TO BE SOLVED: To start speedy rescue work by incorporating a transmitter which sends a weak signal of single frequency in an accessory or forming the transmitter in an accessory shape, etc., and putting it on the body at all times. ;SOLUTION: A detector is composed of a transmitter T. This transmitter T is formed by putting a power source B, a transmitting circuit D, and an output part P equipped with an extremely small antenna A in a case which is nearly as large as or smaller than, for example, a button battery of general size. This transmitter T itself can, therefore, be incorporated in an accessory such as a tiepin or bracelet or formed integrally with it. Anybody puts on the transmitter T and then even if the person meets with a disaster such as house collapse in case of an earthquake and is left in the house, the sent signal from the transmitter T put on the body is received by a receiver, so that the victim can expect rescue without fail.;COPYRIGHT: (C)1997,JPO
