Patent ID: 6850158

Claim:
A tracking system for tracking a plurality of sets of keys, said system including: a base unit including a housing having a back wall, a front wall and a peripheral wall extending between said front and back walls, said front wall having a plurality of docking stations therein, each of said docking stations including a first mating member, a door being hingedly attached to an outer edge of said peripheral wall for selectively positioning in a closed position extending over said front wall or an open position away from said front wall; a plurality of actuators being mounted on said front wall, each of said actuators being relatively adjacent to one of said docking stations and being operationally coupled thereto, a power supply being electrically coupled to each of said actuators; a plurality of transmitters, each of said transmitters being adapted for transmitting a different wireless signal, each of said transmitters including a second mating member adapted for coupling with one of said first mating members, each of said transmitters having a size and shape adapted for positioning in one of said docking stations, each of said transmitters having a different color; a plurality of receiving devices, each of said receiving devices being adapted for receiving a wireless signal transmitted from a corresponding one of said transmitters, each of said receiving devices including; a casing having a color corresponding to a color of said corresponding one of said transmitters, said casing having an aperture extending therethrough; a receiver being mounted in said casing and adapted for receiving one of said signals transmitted by said transmitters; a sound emitter for emitting an audible sound being mounted in said casing and being operationally coupled to said receiver, wherein said sound emitter emits a sound when said receiver receives a signal; a light emitter being mounted on said casing and being operationally coupled to said receiver, wherein said light emitter is turned on when said receiver receives a signal; a power supply being mounted in said casing; and a mobile transmitting unit including a single docking station for removably receiving one of said transmitters, said single docking station including a first mating member, a switch being electrically coupled to said single docking station, a power supply being electrically coupled to said single docking station.
