a battery configured to power the transceiver circuit and the user interface element; and

a housing containing the transceiver circuit, the user interface element, and the battery, wherein the housing is integrated with a component of the vehicle.

2. The trainable transceiver unit of claim 1, wherein the housing is integrated with a mirror assembly of the vehicle, wherein the transceiver circuit, the user interface element, and the battery are part of the mirror assembly.

3. The trainable transceiver unit of claim 1, wherein the housing is integrated with at least one of:

a visor of the vehicle, an instrument panel of the vehicle, and a headliner of the vehicle;

wherein the battery is contained within one of the visor, the instrument panel, and the headliner.

4. The trainable transceiver unit of claim 1, wherein the battery is configured to power only the trainable transceiver unit.

5. The trainable transceiver unit of claim 1, wherein the battery is a long-life battery configured for performance at a range of temperatures at which the vehicle operates.

6. The trainable transceiver unit of claim 1, wherein the battery is a lithium battery contained within a mirror assembly of the vehicle.

7. The trainable transceiver unit of claim 1, wherein the battery includes a hybrid layer capacitor and a lithium cell.

8. The trainable transceiver unit of claim 1, wherein the battery is configured to supply a direct current, the trainable transceiver unit further comprising:

a user-operable switch movable between an open position and a closed position, wherein moving the user-operable switch into the closed position causes the transceiver circuit to transmit a control signal; and

a capacitor arranged in series with the user-operable switch, wherein the capacitor is configured to prevent the direct current from draining the battery if the user-operable switch is maintained in the closed position.

9. The trainable transceiver unit of claim 1, further comprising an antenna coupled to the transceiver circuit;

wherein the antenna is a dipole antenna configured to transmit a differential control signal to a remote electronic device.

10. The trainable transceiver unit of claim 1, further comprising an energy harvesting device;

wherein the energy harvesting device is configured to charge at least one of;

the battery and a capacitor.

11. The trainable transceiver unit of claim 10, wherein the energy harvesting device is at least one of:

a mechanical energy capture device, a piezoelectric energy capture device, a solar energy capture device, and an electromagnetic energy capture device.

12. The trainable transceiver unit of claim 1, further comprising a user input device;

wherein the transceiver circuit is configured to transmit a control signal in response to an input received via the user input device.

13. A mirror assembly for mounting in a vehicle, the mirror assembly including:

a transceiver circuit configured to communicate with a remote electronic device;

a battery configured to power the transceiver circuit; and

a mirror assembly housing containing the transceiver circuit and the battery.

14. The mirror assembly of claim 13, wherein the mirror assembly is a rear view mirror assembly for the vehicle.

15. The mirror assembly of claim 13, wherein the mirror assembly is configured to operate as a standalone unit without requiring any wired connections external to the mirror assembly housing.

16. The mirror assembly of claim 13, further comprising:

a partially-transmissive reflective surface covering an opening in the mirror assembly housing; and

an electronic display contained within the mirror assembly between the reflective surface and the mirror assembly housing, wherein the electronic display is configured to present visual information to a vehicle occupant through the partially-transmissive reflective surface.

17. The mirror assembly of claim 16, wherein the electronic display is configured to present an indication of an amount of energy remaining in the battery through the partially-transmissive reflective surface.

18. The mirror assembly of claim 17, further comprising:

a control circuit configured to monitor the amount of energy remaining in the battery;

wherein the control circuit is configured to cause the electronic display to present an indication of the amount of energy remaining in the battery in response to at least one of;

the amount of energy remaining in the battery dropping below a threshold energy value, and a voltage produced by the battery dropping below a threshold voltage.

19. The mirror assembly of claim 17, further comprising a user input device;

wherein the electronic display is configured to present the indication of the amount of energy remaining in the battery in response to an input received via the user input device.

20. The mirror assembly of claim 16, wherein the partially-transmissive reflective surface includes a layer of electrically-conductive material, wherein a portion of the electrically-conductive material is electrically isolated from a remainder of the electrically-conductive material.
