Abstract

Abstract A locating device has a locating circuit having a oscillator/counter logic circuit, a reset circuit, a reset beep circuit, an enable flip-flop, a delay flip-flop, a mux (multiplexer) flip-flop a mux logic circuit and a piezo oscillator circuit. The locating device is generally designed to assist the user to locate an object of which the locating device is a part. The preferred embodiment of the device is especially useful to determine the location of a misplaced television remote control. The alternative embodiment of the device could also be used to locate an object such as a credit card, locate an animal when lost or to find person on which the device is carried as a game. The locating device may also be used to reduce the occurrences of misplacement of objects or items (credit cards, ID cards, etc.) from their proper place or to alert a person when the object or item is in an improper place. The alternative embodiment has mode switch to control the audio alarm emission cycle.
