Environment friendly remote control
View Patent ↗A remote control is suggested, which comprises an electric signal transmitter being supplied with energy from an electrical energy storage device. The remote control comprises a generator for converting mechanical energy into electrical energy to be stored in the electrical energy storage device. The remote control is provided with a display indicating an empty electrical energy storage device. The display informs the user immediately and unambiguously about the situation that he has to recharge the energy storage of the remote control before he tries to send out a command in vain.
1. A remote control, comprising:
an electric signal transmitter which is supplied with energy from an electrical energy storage device;
means for detecting a state of the electrical energy storage device; and
wherein the remote control is provided with a display indicating an empty electrical energy storage device, wherein the display includes an LCD display which is covered by a mask, and wherein the mask is tinted and provided with openings.
2. The remote control according to claim 1 , wherein the LCD display, when activated, conceals the openings in the mask.
3. The remote control according to claim 1 , wherein the openings of the mask make an indication visible if the LCD display is not energised.
4. The remote control according to claim 1 , wherein the electric signal transmitter transmits infrared light signals or radio frequency signals.
5. The remote control according to claim 1 , further comprising a generator for converting mechanical energy into electrical energy to be stored in the electrical energy storage device.
6. A remote control device, comprising:
means for transmitting signals;
means for detecting a state of an energy source that provides the transmitting means with energy; and
means for providing a display indicating if the energy source is in an empty state, wherein the display includes an LCD display covered by a mask, and the mask is tinted and includes openings.
7. The remote control device according to claim 6 , wherein the LCD display, when activated, conceals the openings in the mask.
8. The remote control device according to claim 6 , wherein the openings of the mask make an indication visible if the LCD display is not energised.
9. The remote control device according to claim 6 , wherein the transmitting means transmits infrared light signals or radio frequency signals.
10. The remote control device according to claim 6 , further comprising means for converting mechanical energy into electrical energy to be stored in the energy source.
