Abstract

A RF communication device (100, 200, 300) employs a mirrored surface (109, 209, 309). The mirrored surface (109, 209) contains a display area (108, 208) that may be used to output operational information of the RF communication device (100, 200), such as signal strength and status information, to a user.

Claims

1. A radio frequency (RF) communication device for operating in a RF communication system, the RF communication device comprising:

a RF receiver;

a housing; and

a mirror for reflective viewing positioned in the housing, the mirror having a planar uninterrupted outer surface, a boundary defined by the housing and a transparent window, the transparent window positioned behind the outer surface and positioned within the boundary, the transparent window for projecting information associated with the RF communication system, the information comprising a phone number.

2. A radio frequency communication device in accordance with claim 1 wherein the radio frequency communication device is a pager.

3. A radio frequency communication device in accordance with claim 1 further comprising a display coupled to the RF receiver, the display disposed on a first side of the mirror and juxtaposed with the transparent window to be viewable on a second side of the mirror.

4. A radio frequency communication device in accordance with claim 3 wherein the display is an alphanumeric display.

5. A radio frequency communication device in accordance with claim 1 wherein the housing is an automobile rearview mirror assembly.

6. A radio frequency communication device in accordance with claim 1 further comprising a RF transmitter.

7. A radio frequency communication device in accordance with claim 6 wherein the radio frequency communication device is a cellular radiotelephone.

8. A radio frequency communication device in accordance with claim 6 wherein the housing further comprises a first microphone and a first speaker, the first microphone disposed on the housing and coupled to the RF transmitter, the first speaker disposed on the housing and coupled to the RF receiver, the first microphone and the first speaker defining a first audio path.

9. A radio frequency communication device in accordance with claim 8 further comprising a handset having an operational state and a non-operational state, the handset comprising a second microphone and a second speaker, the second microphone coupled to the RF transmitter, the second speaker coupled to the RF receiver, the second microphone and the second speaker defining a second audio path, the radio frequency communication device utilizing the first audio path when the handset is in the non-operational state and, alternatively, utilizing the second audio path when the handset is in the operational state.

10. A radio frequency communication device in accordance with claim 9 further comprising a hang-up cup, the hang-up cup being detachably coupled to at least a portion of the handset and having a detector, the detector to detect attachment of the handset and to indicate that the handset is in the non-operational state when coupled to the hang-up cup and, alternatively, that the handset is in the operational state when detached from the hang-up cup.

11. A radio frequency communication device in accordance with claim 6 further comprising a memory coupled to the RF transmitter to store functional information.

12. A radio frequency communication device in accordance with claim 11 wherein functional information read from the memory is viewable via the transparent window.

13. A radio frequency communication device in accordance with claim 11 wherein the mirrored surface further comprises a touch sensitive area being actuatable to select viewable functional information.

14. A radio frequency communication device in accordance with claim 1 wherein the information is received by the RF receiver.

15. A radio frequency communication device in accordance with claim 6 wherein the information further comprises roaming status information received by the RF receiver.

16. A radio frequency communication device in accordance with claim 6 wherein the information further comprises signal strength information received by the RF receiver.

17. A radio frequency communication device in accordance with claim 6 further comprising a wireless controller comprising a keypad and a wireless transmitter, the keypad being actuatable to generate functional information, the wireless transmitter, responsive to actuation of the keypad, to couple the functional information to the RF transmitter for transmission.

18. A radio frequency (RF) communication device for operating in a RF communication system, the RF communication device comprising:

a RF transceiver to communicate with the RF communication system;

a rear view mirror housing;

a display coupled to the RF transceiver to display information associated with the RF communication system, the information comprising a telephone number, roaming status information and signal strength information; and

a mirror attached to the rear view mirror housing, the mirror being substantially rectangular and defined by longitudinal and transverse axes, the mirror having a planar uninterrupted outer surface and a boundary defined by the rear view mirror housing, the outer surface separated into a display area and a mirrored area, the display area and the mirrored area positioned within the boundary, the display area coupled to the display, the display area being substantially rectangular and defined by longitudinal and transverse axes, the display area further positioned such that the longitudinal axis of the display area is parallel to the longitudinal axis of the mirror to facilitate viewing of the information, the mirrored area to provide rearward reflective viewing, the display area positioned along a lower half of the outer surface to permit viewing of the information and rearward reflective viewing substantially simultaneously.
