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.

Dependent claims

A locating device comprising:

a. a locating circuit comprising 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 and a mux logic circuit and a piezo oscillator circuit;
b. the oscillator/counter logic circuit comprising a plurality of counter flip-flops to generate a first clock delay signal, a second clock delay signal, a third clock delay signal and a clear signal;
c. the reset circuit generating a reset signal to clear the state of the counter flip-flops, in the oscillator/counter logic circuit, to zero and generate a reset* signal to clear the reset beep circuit, the enable flip-flop, the delay flip-flop, and the mux flip-flop;
d. the reset beep circuit supplying a single pulse, preset signal to the enable flip-flop, the enable flip-flop generating an enable signal that triggers the piezo oscillator circuit to drive a piezo alarm element in the piezo oscillator circuit;
e. the clear signal resets the enable flip-flop to control the duration the piezo alarm element is activated, is driven by the oscillator/counter logic circuit;
f. the delay flip-flop, cleared by the reset* signal and set high by the third clock delay signal, supplies a data signal that inhibits the enable flip-flop from being set and enables the mux flip-flop to be set by the next cycle of the third clock delay signal,
g. the mux flip-flop sending a mux state signal to the mux logic circuit;
h. the mux state signal controlling the state of the mux logic circuit to multiplex the first clock delay signal or the second clock delay signal that generates a trigger signal;
i. the enable flip-flop triggered by the trigger signal sets the enable flip-flop setting the enable signal that sets the duration of the activation of the piezo alarm element;
and
j. the piezo oscillator circuit, activated by the enable signal, activates the piezo alarm element to emit an audio alarm signal.
