Abstract
A data transfer hinge is disclosed. Embodiments of the present invention provide a door hinge that facilitates transmission of data from LAN wiring in a building through a door frame to a door mounted device. Power and ground connections can also pass through the hinge. Channels (207, 211, 607, 611) run in each leaf from an edge coincident with the knuckles of the leaf to a passageway (110, 112) in the face of the leaf. Twisted pairs of data wires (106, 108) having a specified number of twists per unit length run through the passageway and the channels in the leaves. Each wire of a twisted pair is of a gauge and has insulation of a specified thickness and permittivity so as to cooperate with the channel to maintain an even distribution of capacitance and appropriate impedance for connection within a local area network.
