Abstract

A device for locating an object such as a vehicle in a parking lot by remotely actuating playback circuitry in communication with a loudspeaker disposed with the object. The device is capable of recording and playing back audio signals from any number of sources. A portable transmitter carried by a user can activate the playback circuitry from a distance of at least several hundred feet and the loudspeaker can be heard from a similar distance.

Claims

1. An apparatus for locating an object comprising:

an input port;

conversion circuitry in communication with said input port;

recording circuitry in communication with said conversion circuitry; and

remotely actuate-able playback circuitry in communication with said recording circuitry, said playback circuitry including a loudspeaker disposed with said object.

2. The apparatus according to claim 1 wherein said conversion circuitry is adapted to receive an audio signal from said input port in a first encoded format and output a digital signal representing said audio signal to said recording circuitry, said digital signal being formatted for storage in said recording circuitry.

3. The apparatus according to claim 2 wherein said first encoded format comprises one of MP3 of WAV files.

4. The apparatus according to claim 1 wherein said recording circuitry includes memory circuitry.

5. The apparatus according to claim 4 wherein said memory circuitry comprises removable flash memory cards.

6. The apparatus according to claim 1 wherein said playback circuitry includes digital to analog conversion circuitry in communication with said memory and with amplifier circuitry, said amplifier circuitry being adapted to drive said loudspeaker.

7. The apparatus according to claim 6, wherein said loudspeaker produces sound that can be heard from a range of about 1000 feet.

8. The apparatus according to claim 1 wherein said playback circuitry comprises a radio frequency receiver adapted to receive a radio frequency actuation signal from a remote transmitter, wherein upon receipt of said actuation signal by said receiver, said playback circuitry is actuated to playback an audio stream stored in said recording circuitry.

9. The apparatus according to claim 1 further comprising a portable transmitter adapted for remotely actuating said playback circuitry.

10. The apparatus according to claim 1 wherein said input port comprises at least one of a USB port, an electrical connector port, or an optical connector port.

20. The apparatus according to claim 1 comprising:

means for transferring pre-recorded audio signals to said recording circuitry in communication with said recording circuitry.

21. The apparatus according to claim 1 comprising:

means for selecting at least one of a plurality of pre-recorded audio signals for communication to said recording circuitry.

22. The apparatus according to claim 1 comprising:

means for remotely adjusting the volume of said loudspeaker.

23. The apparatus according to claim 1 comprising:

means for selecting one of a plurality of audio signals stored in said recording circuitry to be played back by said remotely actuate-able playback circuitry.

11. An apparatus for locating a vehicle in a parking lot comprising:

an input port comprising at least one of a USB port, an electrical connector or an optical connector;

conversion circuitry in communication with said input port;

recording circuitry in communication with said conversion circuitry;

wherein said conversion circuitry is adapted to receive an audio signal from said input port in a first encoded format and output a digital signal representing said audio signal to said recording circuitry, said digital signal being formatted for storage in said recording circuitry; and

remotely actuate-able playback circuitry in communication with said recording circuitry, said playback circuitry comprising digital to analog conversion circuitry in communication with said recording circuitry and with amplifier circuitry, said amplifier circuitry being adapted to drive a loudspeaker disposed with said vehicle, and a radio frequency receiver adapted to receive a radio frequency actuation signal from a remote transmitter, wherein upon receipt of said actuation signal by said receiver, said playback circuitry is actuated to playback an audio stream stored in said recording circuitry by driving said loudspeaker.

12. The apparatus according to claim 11 further comprising a portable transmitter adapted for remotely actuating said playback circuitry.

13. An apparatus for locating an object comprising:

an input port;

recording circuitry in communication with said input port and adapted to receive and store an audio signal from said input port; and

conversion circuitry in communication with said recording circuitry and adapted to receive said audio signal from said recording circuitry in a first format, convert said audio signal to an output formatted signal and communicate said output formatted signal to remotely actuate-able playback circuitry including a loudspeaker disposed with said object.

14. The apparatus for locating an object according to claim 13 further comprising a portable transmitter adapted for remotely actuating said playback circuitry.

15. A method for locating an object comprising:

disposing a loudspeaker with said object;

recording an audio signal;

playing back said audio signal through said loudspeaker upon remote transmission of an actuation signal; and

determining said object'"'"'s location by audibly tracking the source of said played back audio signal.

16. A method according to claim 15 wherein said object is a vehicle.

17. The method according to claim 15 further comprising:

providing a communication link between a microphone and recording circuitry for recording a voice signal to said recording circuitry.

18. The method according to claim 15 further comprising:

providing a communication link between a recorded audio source and recording circuitry for recording an audio signal from said recorded audio source.

19. The method according to claim 15 further comprising:

recording said audio signal on recording circuitry having electronic memory, said recording circuitry being in communication with playback circuitry adapted for amplifying and playing back said audio signal through said loudspeaker upon receipt by said playback circuitry of a remotely transmitted actuation signal.
