Intrapersonal data communication system

A mount interface coupled to a headgear system, the mount interface configured to engage with mounting hardware to secure a local device to the headgear system, the mount interface comprising:

• a mounting plate configured to abut with a corresponding surface on the mounting hardware to secure the mounting hardware to the headgear system;
• an optical connector comprising a cavity in the mounting plate and a transparent window within the cavity;
• a fiber optic cable at least partially contained within the mounting plate, the fiber optic cable configured to transmit an optical signal;
• a redirection element contained within the mounting plate, the redirection element configured to redirect a path of the optical signal leaving an end of the fiber optic cable to the transparent window or to redirect a path of an optical signal transmitted through the transparent window to the end of the fiber optic cable;
• an electrical connector on an exterior surface of the mounting plate;
• and
• an electrical cable at least partially contained within the mounting plate, the electrical cable electrically coupled to the electrical connector,
• wherein, when engaged with the mounting hardware, the optical connector is aligned with a corresponding optical connector on the mounting hardware and the electrical connector is aligned with a corresponding electrical connector on the mounting hardware.

An optical digital signal bridge for use in a headgear system to direct optical digital signals from a local device to a fiber optic bundle, the optical digital signal bridge comprising:

• a housing;
• a cavity in the housing;
• a transparent window within the cavity;
• an optical element within the cavity, the optical element having an optical power greater than 0;
• and
• a fiber optic bundle comprising a multistrand fiber optic cable grouped tightly together and surrounded by a jacket, wherein each of the component multistrand fiber optic cables has a cross-section with a diameter that is less than 0.2 mm, and wherein a diameter of a cross-section of the fiber optic cable is less than 2 mm;
• wherein the optical element is configured to focus an optical digital signal onto an end of the fiber optic bundle, and
• wherein a path of the fiber optic bundle within the housing changes direction by about 90 degrees, the fiber optic bundle having a bend radius of curvature of between 2 mm and 20 mm.
