Abstract: 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.

Abstract: A test fixture has a flexible plastic cable that acts as a waveguide. The Device-Under-Test (DUT) is a small transceiver and antenna that operate in the Extremely High-Frequency (EHF) band of 30-300 GHz. The size of the DUT transceiver is very small, limiting the power of emitted electromagnetic radiation so that close-proximity communication is used. The envelope for reception may only extend for about a centimeter from the DUT transceiver, about the same size as the test socket. A slot is formed in the test socket very near to the antenna. The slot receives one end of the plastic waveguide. The slot extends into the envelope by the DUT transceiver so that close-proximity radiation is captured by the plastic waveguide. The waveguide has a high relative permittivity and reflective metalized walls so that the radiation may be carried to a receiver that is outside the envelope.

Abstract: An electronic device may include a dielectric substrate, an electronic circuit supported by the substrate, for processing data, and a communication unit having an antenna. The communication unit may be mounted to the substrate in communication with the electronic circuit for converting between a first EHF electromagnetic signal containing digital information and a data signal conducted by the electronic circuit. The electromagnetic signal may be transmitted or received along a signal path by the antenna. An electromagnetic signal guide assembly may include a dielectric element made of a dielectric material disposed proximate the antenna in the signal path. The electromagnetic signal guide may have sides extending along the signal path. A sleeve element may extend around the dielectric element along sides of the dielectric element. The sleeve element may impede transmission of the electromagnetic signal through the sides of the dielectric element.

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: 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: 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.

Abstract: A communication device employs a contactless secure communication interface to transmit and receive data with a computing device using close proximity extremely high frequency (EHF) communication. The communication device and the computing device periodically initiate a discovery operation mode, whereby the devices periodically transmit identifying information about the respective devices and listen for identifying information from the other device. Upon completion of the discovery mode operation, the devices enter a link-training operation mode and exchange capability information about the respective devices. During transport mode operation the communication device employs methods to manage access to data stored on the communication device by encrypting the data using one or a combination of training information or capability information as a basis for generating an encryption key.

Abstract: A system for sensing proximity using EHF signals may include a communication circuit configured to transmit via a transducer an EM signal at an EHF frequency, and a proximity sensing circuit configured to sense a nearby transducer field-modifying object by detecting characteristics of a signal within the communication circuit. A system for determining distance using EHF signals may include a detecting circuit coupled to a transmitting communication circuit and a receiving communication circuit, both communication circuits being mounted on a first surface. The transmitting communication circuit may transmit a signal toward a second surface, and the receiving communication circuit may receive a signal relayed from the second surface. The detecting circuit may determine distance between the first surface and a second surface based on propagation characteristics of the signals.
