Abstract
PURPOSE: To obtain a wrist watch capable of alarming for the bearer's baggage left behind by a method wherein an activation of an alarm circuit is controlled in answer to a receiving output of an output signal from a baggage.
CONSTITUTION: A signal from a transmitter fitted in a baggage is not received by a receiving antenna 13 when the antenna moves far from the baggage, but an output of a level discrimination circuit 7 is inverted to a low level. Said inverted output and a high level output from a switch means 1 being generated by closing the circuit are entered into an NAND gate 9 and the output of the gate 9 becomes a high level, thus, actuating an alarm circuit 8. Accordingly, when a means 10 is kept closed, and if a baggage is left behind, an alarm of a wrist watch operates as a warning system, thus, enabling early to discover a baggage left behind and forgotten.
