Abstract: EHF communication systems described herein can selectively implement any one of the USB standards by mapping appropriate USB signal conditions over an EHF contactless communication link. The EHF contactless communication link may serve as an alternative to conventional board-to-board and device-to-device connectors, and as such enables wired connection USB signaling protocols to be used in a non-wired environment provided by the EHF contactless communications link. Use of a USB protocol over the EHF communications link can be accomplished by establishing the EHF link between counterpart EHF communication units, and then by establishing the appropriate USB protocol over the link.

Abstract: A Physical Layer (PHY) of a host system of an electronic device may be implemented as a contactless PHY (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. A virtualized contactless Physical Layer (VcPHY) may comprise a contactless Physical Layer (Host-cPHY), and a contactless Link Layer (cLINK) for coupling a conventional Link Layer (LINK) with the contactless Physical Layer (Host-cPHY). Multiple data streams may be transported over the EHF contactless link over a range of frequencies.

Abstract: Embodiments discussed herein refer to systems, methods, and circuits for establishing EHF contactless communications links. The EHF contactless communication link may serve as an alternative to conventional board-to-board and device-to-device connectors. The link may be a low-latency protocol-transparent communication link capable of supporting a range of data rates. The link may be established through a close proximity coupling between devices, each including at least one EHF communication unit. Each EHF unit involved in establishing an EHF communication link may progress through a series of steps before data can be transferred between the devices. These steps may be controlled by one or more state machines that are being implemented in each EHF communication unit.

Abstract: “Smart” connectors with embedded processors, measurement circuits and control circuits are disclosed for establishing a “contactless” radio frequency (RF) electromagnetic (EM) Extremely High Frequency (EHF) communications link between two electronic devices having host systems. The connectors are capable of monitoring, controlling, and directing (managing) link operation to dynamically adapt to conditions, as well as monitoring and altering (or modifying) data passing through the connector, and selecting a protocol suitable for a communications session. The connectors are capable of identifying the type of content being transferred, providing authentication and security services, and enabling application support for the host systems based on the type of connection or the type of content. The connectors may operate independently of the host systems, and may perform at least one of sensing proximity of a nearby object; detecting a shape of a nearby object; and detecting vibrations.

Abstract: Shielded extremely high frequency (EHF) connector assemblies are disclosed herein. In some embodiments, a first extremely high frequency (EHF) shielded connector assembly configured to be coupled with a second EHF shielded connector assembly. The first EHF connector assembly can include a first EHF communication unit operative to contactlessly communicate EHF signals with a second EHF communication unit included in the second EHF shielded connector assembly. The first connector can include a connector interface that includes a configuration to interface with a respective connector interface of the second EHF shield connector assembly, and several different material compositions that, in conjunction with the configuration, provide shielding to prevent or substantially reduce EHF signal leakage when the first EHF assembly connector is coupled to the second EHF assembly connector and the first EHF communication unit is contactlessly communicating EHF signals with the second EHF communication unit.

Abstract: 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.
