Abstract

A radio device (10) receives optical control signals from a remote control apparatus (22). In one embodiment, both the radio device and remote control apparatus include optical transmitters (58) and receivers (60) so that control and information signals may provided to and received from the radio'"'"'s operator. In another embodiment, the radio () provides a light signal to the remote control apparatus () that either permits or prohibits (80) the light signal'"'"'s return to the radio. In this way, the presence or absence of the return light signal comprises optical control signals to control the radio'"'"'s operation.

Claims

1. An optically controlled radio, comprising:

a radio device including;

a controller means for controlling at least a portion of said radio device in response to an optical control signal; and

a light source disposed within the radio device for generating a light signal;

a remote means for providing said optical control signal including means for receiving said light signal and switch means for selectively permitting or prohibiting passage of said light signal to provide said optical control signal; and

an optical communication channel disposed between said radio device and said remote means.

2. The radio of claim 1, wherein said radio device includes radio frequency transmitting means for transmitting an information signal to provide a radio frequency signal.

3. The radio of claim 2, wherein said remote means includes means for processing voice or data signals to provide optical data signals, and said radio device includes means for converting said optical data signals into said information signal.

4. The radio of claim 1, wherein said radio device includes radio frequency receiver means for receiving a radio frequency signal to provide a recovered information signal.

5. The radio of claim 4, wherein said radio device includes means for converting said recovered information signal into an optical information signal, and means for transmitting said optical information signal to said remote means.

6. The radio of claim 5, wherein said remote means includes means for receiving said optical information signal from said radio device and means for presenting a signal derived from said optical information signal via a display means or a speaker means.

7. The radio of claim 1, wherein said optical communication channel comprises at least one fiber optic link.
