Abstract

A system locating portable devices includes a fob wirelessly matched to a handheld device. The fob includes a transmitter, receiver, controller and memory storing codes/signals matching signals stored at a handheld device. The codes/signals supporting bi-directional communications between the fob and handheld device. The fob and handheld device can discover locations of each other by sending radio frequency signals from memory that are recognizable by each other. Matching and reciprocal discovery of device locations can be supported by Bluetooth communications.

Claims

1. A system for reciprocal locating of wirelessly paired electronic devices, comprising a fob including a transmitter, receiver, controller and memory that is wirelessly matchable to a handheld device including a transmitter, receiver, controller and memory, wherein memory in the fob and handheld device stores unique signals or codes supporting bi-directional communications between the fob and handheld device and wherein the fob and handheld device can discover locations of each other by sending a radio frequency signal from memory that is recognizable by each of the fob and handheld device.

2. The system of claim 1, wherein the fob and handheld device communicate using Bluetooth wireless communications.

3. The system of claim 1 wherein the fob is attached to a keychain and the handheld device includes at least one of a cellular phone, PDA or smartphone.

4. The system of claim 2 wherein the fob is attached to a keychain and the handheld device includes at least one of a cellular phone, PDA or smartphone.

5. The system of claim 3, wherein the fob and handheld device communicate using Bluetooth wireless communications.

6. A system for locating portable devices, comprising:

a fob including a memory storing a frequency code matched to a remote handheld device, a transmitter and receiver for communicating with the remote handheld device, controller managing communication with the remote handheld device, and a speaker providing an audible signal when the fob receives a signal from the remote handheld device.

7. The system of claim 6, wherein the fob is wirelessly matchable to a remote handheld device with unique signals or codes stored in the fob and the remote handheld device supporting bi-directional communications between the fob and handheld device.

8. The system of claim 6, wherein the fob and remote handheld device can discover locations of each other by sending a radio frequency signal from memory that is recognizable by each of the fob and handheld device.

9. The system of claim 6, wherein said fob and remote handheld device communicate using Bluetooth wireless communications.

10. A method for discovering the location of a lost fob or handheld device using a fob or handheld device that is not lost, the method comprising:

wirelessly matching a fob and handheld device using radio frequencies;

sending an RF signal from transmitter 1 to receiver 2;

receiving the RF signal with receiver 2;

generating an audible signal by a controller associated with receiver 2 after it receives the RF signal.

11. The method of claim 10, wherein said step of wirelessly matching the fob and the handheld device includes the use of Bluetooth discovery.
