Patent ID: 7392068

Claim:
A power delivery system comprising: a contactor device including a contactor body defining a contact surface shaped and dimensioned to make physical contact with an adaptor surface of an adaptor device; a plurality of first electrical contacts of a first and second polarity on the contactor body at or adjacent the contactor surface, wherein electrical contacts of the first polarity are interspersed with electrical contacts of the second polarity, and an electrical contact of the first polarity is to be dynamically paired with an electrical contact of the second polarity to close an electrical circuit between the contactor device and an adaptor device having second electrical contacts when the adaptor device is brought into physical contact with the contactor surface, wherein the adaptor device includes an identification mechanism to provide compatible voltage and polarity settings to the power delivery system, wherein the identification mechanism further comprises a memory storage comprising handshaking information including information selected from the group comprising identification information for the adaptor device, settings for the power delivery system to energize the adaptor device, and authentication information required to connect the adaptive device to a computer network.
