COUPLING MANAGER FOR MANAGING A MULTIMODAL ELECTRICAL COUPLING AND METHOD OF OPERATION
20220083100 · 2022-03-17 ·

A multimodal electrical coupling, which may be comprised of any pair of conductive regions in a surface, is selectively coupled to a coupling communications interface in response to the detection of an article connected across the terminals of the coupling. The coupling communications interface obtains data characterising the article, and determines whether this information is consistent with the supply of power to the article, or communication with the article, in particular in terms of the power requirements of the article, and/or the identity, and corresponding authorisation status of the article. Where interaction is determined to be allowable, a transducer module is brought into connection with the multimodal electrical coupling, at which time the coupling communications interface may be decoupled. A corresponding reporting interface for integration in articles is also presented.
