Abstract
A contactless, electromagnetic (EM) replacement for cabled Standards-based interfaces (such as USB, I2S) which handles data transfer requirements associated with the Standard, and capable of measuring and replicating relevant physical conditions on data lines so as to function compatibly and transparently with the Standard. A contactless link between devices having transceivers. A non-conducting housing enclosing the devices. A dielectric coupler facilitating communication between communications chips. Conductive paths or an inductive link providing power between devices. An audio adapter communicates over a contactless link with a source device, and via a physical link with a destination device such as a conventional headset. Power may be provided to the adapter from the source device, and by the adapter to the destination device.
