Abstract

A remote controlling device (12) having a first transceiver (9) and first processor (16) for controlling a remote controlled apparatus (18) having a second wireless transceiver (20) and a second processor (24). The processors can be programmed to measure a signal quality level of signals transmitted by the wireless transceiver(s) to redirect the remote controlled apparatus if the signal quality level falls below a predetermined threshold. The processor(s) can be further programmed to transmit control signals to redirect (56) the remote controlled apparatus toward the remote controlling device or to safely stop the remote controlled apparatus or to cause the remote controlled apparatus to meander so long as the signal quality level stays above the predetermined threshold.

Claims

1. A remote controlling device, comprising:

a wireless transceiver for controlling a remote controlled apparatus having a wireless transceiver; and

a processor coupled to the wireless transceiver of the remote controlling device, wherein the processor is programmed to;

measure a signal quality level of signals transmitted by the wireless transceiver of the remote controlled apparatus; and

alerting a user when the signal quality level falls below a predetermined threshold.

2. The remote controlling device of claim 1, wherein the wireless transceiver in the remote controlling device and in the remote controlled apparatus use the IEEE 802.15.4 Standard.

3. The remote controlling device of claim 1, wherein the processor is programmed to measure received signal strength indicator measurements or bit error rate.

4. The remote controlling device of claim 1, wherein the predetermined threshold is a programmable setting.

5. The remote controlling device of claim 1, wherein the remote controlling device is further programmed to transmit control signals to redirect the remote controlled apparatus if the signal quality level falls below the predetermined threshold.

6. The remote controlling device of claim 5, wherein the processor is further programmed to transmit control signals to redirect the remote controlled apparatus toward the remote controlling device or to safely stop the remote controlled apparatus or to cause the remote controlled apparatus to meander so long as the signal quality level stays above the predetermined threshold.

7. The remote controlling device of claim 1, wherein the wireless transceiver in the remote controlled apparatus also measures a signal quality level and transmits a warning signal to the remote controlling device when the signal quality level measured at the remote controlled apparatus falls below a predetermined threshold.

8. The remote controlling device of claim 1, wherein the remote controlling device comprises a two-way radio, a cellular phone, a cordless home phone, a compute with wireless capability, a radio controlled toy controller, or a smart phone.

9. The remote controlling device of claim 1, wherein the remote controlled device comprises a remote controlled car, boat, aircraft, or robot.

10. A system for controlling a remote controlled apparatus, comprising:

a first wireless transceiver in a remote controlling device for controlling the remote controlled apparatus;

a second wireless transceiver in the remote controlled apparatus; and

a processor coupled to the second wireless transceiver of the remote controlling device, wherein the processor is programmed to;

measure a signal quality level of signals transmitted by the first wireless transceiver;

redirect the remote controlled apparatus if the signal quality level falls below a predetermined threshold.

11. The system of claim 10, wherein the remote controlled apparatus is a remote controlled car, a remote controlled boat, or a remote controlled aircraft and the remote controlling device comprises a two-way radio, a cellular phone, a cordless home phone, a computer with wireless capability, a radio controlled toy controller, or a smart phone.

12. The system of claim 10, wherein the first and second wireless transceivers use the IEEE 802.15.4 Standard.

13. The system of claim 10, wherein the system further comprises a processor coupled to the first wireless transceiver, wherein the processor coupled to the first wireless transceiver is programmed to measure a signal quality level of signals transmitted by the second wireless transceiver and to transmit signals to redirect the remote controlled apparatus when a signal quality level of the signals transmitted by the second wireless transceiver falls below a predetermined threshold.

14. The system of claim 13, wherein the processor coupled to the first wireless transceiver or the processor coupled to the second wireless transceiver is programmed to measure received signal strength indicator measurements or bit error rate.

15. The system of claim 10, wherein the predetermined threshold is a programmable setting.

16. The system of claim 10, wherein the remote controlling device further comprises a user alert that warns a user when the signal quality level falls below the predetermined threshold.

17. The system of claim 10, wherein the processor in the remote controlled apparatus or a processor in the remote controlling device is further programmed to redirect the remote controlled apparatus toward the remote controlling device or to safely stop the remote controlled apparatus or to cause the remote controlled apparatus to meander so long as the signal quality level stays above the predetermined threshold.

18. The system of claim 10, wherein the second wireless transceiver transmits a warning signal to the remote controlling device when the signal quality level measured at the remote controlled apparatus falls below a predetermined threshold.

19. A method of controlling a remote controlled apparatus, comprising the steps of:

measuring a signal quality level of at least one signal between the remote controlled apparatus and a remote controlling device that controls the remote controlled apparatus;
