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 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: Tightly-coupled near-field transmitter/receiver pairs are deployed such that the transmitter is disposed at a terminal portion of a first conduction path, the receiver is disposed at a terminal portion of a second conduction path, the transmitter and receiver are disposed in close proximity to each other, and the first conduction path and the second conduction path are discontiguous with respect to each other. In some embodiments of the present invention, close proximity refers to the transmitter antenna and the receiver antenna being spaced apart by a distance such that, at wavelengths of the transmitter carrier frequency, near-field coupling is obtained. In some embodiments, the transmitter and receiver are disposed on separate substrates that are moveable relative to each other. In alternative embodiments, the transmitter and receiver are disposed on the same substrate.

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: 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.

Abstract: A test system includes a test socket assembly for capturing low energy electromagnetic emissions from radio frequency (RF) integrated circuits (ICs). The test socket assembly is structured to direct electromagnetic radiation from the device under test (DUT) to a socket port coupled to one end of a waveguide for transmission to a tester. The combination of the materials comprising the socket assembly is selected to more efficiently couple electromagnetic emissions from the DUT into the waveguide. For example, a reflective plane with an adjustable position may be located below the DUT in order to increase coupling of electromagnetic radiation from the DUT into the waveguide.

Abstract: Establishing a communication link may include transmitting by a first device an unmodulated first electromagnetic EHF signal and receiving by a second device the first electromagnetic EHF signal. The second device may determine whether the received first electromagnetic EHF signal indicates that a first shield portion and a second shield portion are in alignment. The transmission of a modulated second electromagnetic EHF signal may be enabled when the received first electromagnetic EHF signal indicates that both the shield portions are in alignment and may be disabled when the received first electromagnetic EHF signal indicates that the first and second shield portions are not in alignment.

Abstract: Display systems that use contactless connectors for transmitting data are provided. The contactless connectors are electromagnetic connectors that form an electromagnetic communications link. The electromagnetic communications link can be established within different locations of the same device, or between two different devices. The communications link can be established using at least two transceivers. The transceivers can be incorporated in different enclosures that are hinged together, or the transceivers can be incorporated within a hinge that enables two enclosures to move with respect to each other. A transceiver can be incorporated into a display device that can receive data from an active surface that has a transceiver. When the display device is placed on the active surface, the display device may serve as an access point to content contained within the active surface.
