    摘要: 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.

    摘要: Data may be transferred from a communication subsystem of a first device to a communication subsystem of a second device contactlessly, at high speed, and without intervention by host processors of either device. Devices may be programmed or personalized at the factory or warehouse, and may personalized at a warehouse or at a point of sale while in the box. Various modes of operation and use scenarios are described. Portions of the devices themselves, or a transmission path between the devices may be shielded against snooping by a material which degrades an EHF signal passing therethrough.

    摘要: A Physical Layer (PHY) of a host system of an electronic device may be implemented as a contactless PHY (Host-cPHY) for extremely high frequency (EHF) contactless communication and the operation of EHF transmitters (TX), receivers (RX) and transceivers (EHF-XCVR) in an extremely high frequency integrated circuit (EHF IC) of the electronic device. The Host-cPHY translates logical communications requests from the Link Layer (LINK) into hardware-specific operations to affect transmission or reception of signals over an EHF contactless link). The Link Layer (LINK) may also be optimized as a contactless Link Layer (cLINK) for EHF contactless communication. Multiple data streams may be transported over the EHF contactless link over a range of frequencies.

    摘要: 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.
