Claims
- 1. A remote control, the remote control comprising:a processing circuit; a memory device, the memory device being responsive to the processing circuit, the memory device storing an output test code, the processing circuit generating an output test signal, the output test signal being representative of the output test code; a first transmitter, the first transmitter being responsive to the processing circuit, the first transmitter transmitting the output test signal; a receiver, the receiver being responsive to the processing circuit, the receiver receiving the output test signal, the receiver outputting the received output test signal to the processing circuit, the processing circuit generating an input test code, the input test code being representative of the received input test signal, the processing circuit comparing the input test code to the output test code, the processing circuit generating a comparison signal, the comparison signal being representative of whether the input test code is substantially equivalent to the output test code; and a second transmitter, the second transmitter being responsive to the processing circuit, the second transmitter transmitting the output test signal.
- 2. A remote control, the remote control comprising:a processing circuit; a memory device, the memory device being responsive to the processing circuit, the memory device storing an output test code, the processing circuit generating an output test signal, the output test signal being representative of the output test code; a first transmitter, the first transmitter being responsive to the processing circuit, the first transmitter transmitting the output test signal; a receiver, the receiver being responsive to the processing circuit, the receiver receiving the output test signal, the receiver outputting the received output test signal to the processing circuit, the processing circuit generating an input test code, the input test code being representative of the received input test signal, the processing circuit comparing the input test code to the output test code, the processing circuit generating a comparison signal, the comparison signal being representative of whether the input test code is substantially equivalent to the output test code; a second transmitter, the second transmitter being responsive to the processing circuit, the second transmitter transmitting the output test signal, the second transmitter including an infrared (IR) light-emitting diode (LED).
- 3. A remote control as defined by claim 1, wherein the processing circuit includes at least one of a microcontroller, a microprocessor, an application specific integrated circuit (ASIC), and a programmable logic device.
- 4. A remote control as defined by claim 1, wherein the first transmitter includes an infrared (IR) light-emitting diode (LED).
- 5. A remote control as defined by claim 1, wherein the receiver includes a photo-diode.
- 6. A remote control as defined by claim 1, further including an indicator, the indicator being responsive to the comparison signal, the indicator indicating whether the input test code is substantially equivalent to the output test code.
- 7. A remote control as defined by claim 6, wherein the indicator includes at least one of a light-emitting diode and a speaker.
- 8. A remote control as defined by claim 1, wherein the remote control has a test mode and at least one button, the test mode being initiated in response to selecting the at least one button, the test mode being terminated in response to selecting the at least one button.
- 9. A remote control as defined by claim 1, wherein the remote control has a test mode, the test mode being initiated in response to an elapse of a first time period, the test mode being terminated in response to an elapse of a second time period.
- 10. A remote control as defined by claim 1, wherein the receiver receives the output test signal following reflection of the output test signal from a reflective surface.
