Communication with a multi-contact pad having a USB application
First Claim
1. An apparatus, comprising;
- an electrical connection pad having an array of four types of electrically conductive contact pads, all conductive contact pads of a given type being electrically connected to all other conductive contact pads of the same type; and
circuitry for connecting said four types of electrical contact pads to, and for communication with, a provided external electrical device; and
an arrangement for making electrical connections, comprising electrically conductive contacts arranged at corners of a first square and corners of a second square, said first square being rotated by substantially forty five degrees with respect to said second square, said squares having a common center, and an electrically conductive contact disposed at said common center, said electrically conductive contact pads of said electrical connection pad being sized, shaped and positioned to make electrical contact with selected ones of said electrically conductive contacts of said arrangement.

Abstract
Apparatus for making an electrical connection in a system requiring four electrical connections, including an electrical connection pad having an array of four types of electrically conductive contacts, all conductive contacts of a given type being electrically connected to all other conductive contacts of the same type; and an arrangement for providing electrical connections to conductive contacts on the pads, the arrangement having electrically conductive pins for making contact with the conductive contacts, wherein the types of electrically conductive contacts include two contacts for power and two separate contacts for signals. The pins may be arranged at corners of a first square and a second square, with the first square being rotated by forty-five degrees with respect to the second square, and a pin located at a common center of both squares. A method of operation of the apparatus, and various applications and configurations for its use.
