Patent ID: 7667590

Claim:
A wireless object locating system for finding a plurality of objects within a target zone, said wireless object locating system comprising: a primary portable controller comprising a plurality of controls and LEDs disposed on an outer surface thereof, a transceiver, a digital signal processor electrically coupled directly to said transceiver, a memory electrically coupled directly to said digital signal processor, said memory including programmable software instructions that cause said primary controller to emit a plurality of search signals having corresponding unique frequencies respectively, and a frequency synthesizer circuit electrically coupled directly to said digital signal processor; and a plurality of secondary controllers directly and removably attached to the plurality of objects respectively, each of said secondary controllers comprising a transceiver having an antenna electrically coupled thereto, a processor operably coupled to said transceiver, a memory electrically coupled directly to said processor, said memory including programmable software instructions that cause said secondary controller to transmit a location signal upon verifying the identity of said corresponding search signal, and a transducer electrically coupled directly to said processor, said transducer emitting an audible and visual signal in response to receiving said search signal; wherein said primary controller further comprises means for simultaneously locating all of said plurality of secondary controllers such that the user is able to simultaneously and independently locate each of the objects during a single time period, said simultaneous locating means comprising a point-to-multipoint network interface circuit electrically coupled directly to said frequency synthesizer circuit such that each of said search signals are sequentially transmitting within the target zone without causing interference between each of said search signals; and an analog to digital converter electrically coupled directly to said transceiver, said converter receiving an analog user input from said controls and converting said analog user input to a digital user input prior to reaching said digital signal processor.
