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 run in each leaf from an edge coincident with the knuckles of the leaf to a passageway in the face of the leaf. Twisted pairs of data wires 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.
