Abstract
Systems and methods for providing an electronic device. The electronic device comprising a circuit configured to: receive a first radio frequency signal from an external communication device; use the first radio frequency signal to modulate an optical signal; and emit the modulated optical signal through free space. The circuit comprises a plurality of optical emitters and a plurality of optical detectors arranged to provide a substantially 180° field of view.

An electronic device, comprising:
- a circuit configured to:
- receive a first radio frequency signal from an external communication device;
- use the first radio frequency signal to modulate an optical signal;
- and
- emit the modulated optical signal through free space;
- wherein the circuit comprises a plurality of optical emitters and a plurality of optical detectors arranged to provide at least a substantially 90° field of view.

A signal converter, comprising:
- a main body;
- and
- a circuit disposed in the main body, the circuit configured to:
- receive a first radio frequency signal from an external communication device;
- use the first radio frequency signal to modulate an optical signal;
- and
- cause the modulated optical signal to be emitted through free space;
- and
- a coupler disposed on the main body and configured to removably couple the signal converter to a helmet;
- wherein the circuit comprises a plurality of optical emitters circumferentially arranged on a top surface of the main body and a plurality of optical detectors supported by sidewalls of the main body in a spaced apart arrangement.
