Abstract

Disclosed is a stimuli providing indicator (107) that is responsive to nearby transmitted radio signals. Fixed and mobile stations may produce such signals. In addition a cellular telephone operating at a high transmit power may be detected. Indicator (107) may be supported by a lens (103) which itself may be supported by at least one head mount (101).

Claims

1. A wireless communication reporter for wearing on a head of a user comprising:

a head mount;

a radio frequency detector circuit (RFDC) having a light emitter supported by the head mount, said radio frequency detector circuit providing a signal, said RFDC responsive to a radio frequency signal above a preset level in a uplink signaling band; and

a lens supported by the head mount, wherein the light emitter or said lens illuminates in response to the signal provided by the radio frequency detector circuit.

2. The wireless communication reporter of claim 1 wherein the light emitter has an anisotropic output directed along a principal ray, wherein said ray points in a direction of the user.

3. A wireless communication reporter for wearing on a head of a user and detecting a radio signal of a radio transmitter comprising:

a head mount having a lens;

a radio frequency detector circuit having an indicator output, said radio frequency detector circuit (RFDC) supported by said head mount, wherein said radio frequency detector circuit comprises an uplink signaling band radio frequency detector; and

an indicator on said lens coupled to the indicator output, wherein said indicator provides stimulus upon the radio uplink radio frequency detector circuit receiving the radio signal.

4. The wireless communication reporter of claim 3 wherein said stimulus comprises a light for illuminating responsive to a signal on the indicator output, whereby the light is predominantly directed toward the head of the user.

5. The wireless communication reporter of claim 4 wherein said head mount further comprises at least one lens.

6. A wireless communication reporter of claim 5 wherein said at least one lens is operatively coupled to said radio frequency detector circuit.

7. The wireless communication reporter of claim 6 wherein said indicator comprises a light emitting diode.

8. The wireless communication reporter of claim 7 wherein said light emitting diode emits light in a direction of the user responsive to a signal of a cellular telephone.

9. The wireless communication reporter of claim 8 wherein said light emitting diode emits little light in a direction away from the user responsive to a signal of a cellular telephone.

10. The wireless communication reporter of claim 7 further comprising a photocell coupled to the light emitting diode wherein low current is provided to the light emitting diode when ambient light is low.

11. The wireless communication reporter of claim 7 wherein the light emitting diode emits light periodically in response to a signal of a cellular telephone.

12. A wireless communication reporter for wearing on a head comprising:

a head mount comprising at least one lens;

a radio frequency detector circuit having an indicator output, said radio frequency detector circuit mounted on said head mount, wherein the radio frequency detector circuit provides a signal on the indicator output based on detecting a cellular telephone uplink signaling channel above a preset level; and

a light emitter, coupled to the indicator output and operative based on said indicator output, said light emitter having an anisotropic output directed along a principal ray, wherein said ray points in a direction of the user.

13. The wireless communication reporter of claim 12 wherein the preset level comprises a locus level.

14. The wireless communication reporter of claim 13 wherein the locus level corresponds to an arms-length space.

15. The wireless communication reporter of claim 14 wherein the locus level corresponds to a body-length space.
