Abstract

Intrapersonal communication systems and methods that provide an optical digital signal link between two or more local devices are disclosed. In some embodiments, the system includes a first signal converter disposed at a first end of the optical digital signal link and configured to convert between electrical digital signals from a first local device and optical digital signals from the optical digital signal link. The system can include an optical connector having a non-contact portion configured to couple optical digital signals between the first signal converter and the optical digital signal link across a gap. The system can include a second signal converter disposed at a second end of the optical digital signal link and configured to convert between electrical digital signals from the second local device and optical digital signals from the optical digital signal link.

Claims

1. A communication system comprising:

an optical digital signal link between a first optical connector having a non-contact portion and a second optical connector having a non-contact portion;

a first signal converter having a first electrical interface and a first optical interface, the first electrical interface configured to receive an electrical digital signal and the first optical interface configured to transmit an optical digital signal, the first signal converter configured to convert the electrical digital signal to the optical digital signal;

the first optical connector having a non-contact portion configured to couple the optical digital signal between the first optical interface of the first signal converter and a first end of the optical digital signal link across a first gap;

a second signal converter having a second electrical interface and a second optical interface, the second optical interface configured to receive the optical digital signal and the second electrical interface configured to transmit a second electrical digital signal, the second signal converter configured to convert the optical digital signal to the second electrical digital signal, wherein the first signal converter and/or the second signal converter comprises an optical transceiver configured to send and receive the optical digital signal;

the second optical connector having a non-contact portion configured to couple the optical digital signal between the second optical interface of the second signal converter and a second end of the optical digital signal link across a second gap; and

a controller configured to direct electrical power to the optical transceiver.

2. The communication system of claim 1, wherein the controller is configured to direct less than or equal to about 500 mW of electrical power to the optical transceiver during transmission of the optical digital signal.

3. The communication system of claim 1, wherein the optical transceiver is configured to operate at a transmission rate that is less than or equal to about 10 Gbps.

4. The communication system of claim 1, wherein the controller is configured to direct less than or equal to about 50 mW of electrical power to the optical transceiver during transmission of the optical digital signal and the transmission of information occurs at a data rate that is less than or equal to about 2 Gbps.
