CROSS-REFERENCE TO RELATED APPLICATION
[0002] The aforementioned applications are incorporated herein by reference in their entirety.
BACKGROUND
[0003] The present invention relates generally to a hot shoe interface capable of transmitting
high speed data.
[0004] Existing data communication interfaces use external connectors that are polarized
and include cables that must be physically mated or de-mated. In order to transmit
video, for example, with a smart phone, a connector must be used, such as an external
cable or docking station. Hot shoe interfaces are known in the art and are advantageous
where ease of connection and disconnection, for example, one-handed connection and
disconnection, is desired. However, existing hot shoe interfaces typically provide
limited electrical coupling between devices, and are often limited to carrying power.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0041] Referring now to the drawings, FIGS. 1-4 illustrate a hot shoe interface configured
to serve as a communication port with a helmet mount assembly and/or other external
accessory device. The hot shoe, generally designated
100, includes a set of contact pads configured to communicate with a set of corresponding
contact pins on a shoe receiver assembly generally designated
200. In certain embodiments, the hot shoe
100 is advantageously disposed on an electrically operated device (not shown) or mounting
unit therefor and serves as a mechanical and electrical attachment point.
[0042] Referring now to FIG. 1, the contact pads or terminals on the hot shoe
100 include one or more of the following: optical interface terminals
101, high speed contact pairs
102 each comprising two pads
110, low speed contact pads
103, high speed drain pad
104, coaxial or radio frequency (RF) contacts
105, power ground pads
106, power drains
107, power pads
108, and shield pad
109. The hot shoe
100 further allows redundant power, ground, and/or control or data signals to pass through
the interface. In certain preferred embodiments, the contact pads are gold plated,
e.g., gold plated brass or gold plated copper, to minimize corrosion. Each high speed
contact pad
110 is electrically coupled to a respective conductor
217 of a twisted pair
218 of conductors. In certain preferred embodiments, the twisted pair
218 of conductors is a twisted pair differential cables configured to provide 90 ohms
of impedance to support high speed transmission performance.
[0043] Each pair of adjacent contacts
110 defines a pair of contact pads
102. The contact pads
