Abstract

A remote control device with assured button functionality includes a case, at least one key located on the case, and at least one key circuit located under the at least one key. Each of the at least one keys corresponds to a compensation capacitance, which also connects to at least one key circuit. A capacitance is generated when a user presses the touch panel and the at least one key circuit is thereby unbalanced, to trigger the remote to generate command signal when the at least one key circuit is electrically connected to the at least one compensation capacitance through the capacitance.

First claim

What is claimed is:

1. A remote control device comprising:
a case;
at least one key located on the case and each of the at least one key comprising a touch panel;
at least one key circuit located under the at least one key; and
at least one compensation capacitance;
wherein each of the at least one key corresponds to one of the at least one compensation capacitance;
each of the at least one key circuit is connected to one of the at least one compensation capacitance through the touch panel, the touch panel generates a capacitance when a user presses the touch panel; and
each of the at least one key circuit triggers the remote control device to generate a signal when each of the at least one key circuit is electrically connected to one of the at least one compensation capacitance through the capacitance, wherein each of the at least one key circuit comprises a Wheatstone bridge circuit.

2. The remote control device according to claim 1 , further comprising a Fresnel lens located on a front end of the case, wherein the Fresnel lens is configured to combine the generated signal.

3. The remote control device according to claim 1 , wherein a value of the at least one compensation capacitance which corresponds to each of at least one key, is relevant to a position of the at least one key located on the case.

4. The remote control device according to claim 1 , further comprising a power supply, wherein the power supply comprises a backup power and a rechargeable battery.

5. The remote control device according to claim 4 , further comprising a wireless charge device, wherein the wireless charge device charges the rechargeable battery.

6. The remote control device according to claim 5 , further comprising a controller, wherein the controller controls the backup power or the rechargeable battery to supply power to the remote control device when the user presses the at least one key.

7. The remote control device according to claim 1 , further comprising a signal generator electrically connects to the at least one key circuit, wherein the signal generator is configured to generate signal.

8. The remote control device according to claim 7 , further comprising a signal transmit device electrically connects to the signal generator, wherein when the signal generator is triggered to generate the signal, the signal generator sends the signal to the signal transmit device, and the signal transmit device transmits the signal to a receiver.

9. The remote control device according to claim 1 , wherein the case is of a cylinder shape.

10. The remote control device according to claim 1 , wherein one portion of the at least one key located at one side of the case, and the other portion of the at least one key located at the other side of the case.
