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.
