Contactless replacement for cabled standards-based interfaces
First Claim
1. An apparatus, comprising:
- an electrical interface configured to communicate electrically with a first device;
a first transducer configured to receive and convert an electromagnetic signal into a first electrical signal, wherein the electromagnetic signal includes a value indicative of a physical condition of a second device, and the physical condition includes at least one of a termination resistance and a drive strength; and
a first circuit configured to;
obtain the value indicative of the physical condition from the first electrical signal; and
reproduce the physical condition.

Abstract
A contactless, electromagnetic (EM) replacement (substitute, alternative) for cabled (electric) Standards-based interfaces (such as, but not limited to USB) which effectively handles the data transfer requirements (such as bandwidth, speed, latency) associated with the Standard, and which is also capable of measuring and replicating relevant physical conditions (such as voltage levels) on data lines so as to function compatibly and transparently with the Standard. A contactless link may be provided between devices having transceivers. A non-conducting housing may enclose the devices. Some applications for the contactless (EM) interface are disclosed. A dielectric coupler facilitating communication between communications chips which are several meters apart. Conductive paths may provide power and ground for bus-powered devices.
