摘要： 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.

摘要： 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.

摘要： A system for transmitting or receiving signals may include an integrated circuit (IC), a transducer operatively coupled to the IC for converting between electrical signals and electromagnetic signals; and insulating material that fixes the locations of the transducer and IC in spaced relationship relative to each other. The system may further include a lead frame providing external connections to conductors on the IC. An electromagnetic-energy directing assembly may be mounted relative to the transducer for directing electromagnetic energy in a region including the transducer and in a direction away from the IC. The directing assembly may include the lead frame, a printed circuit board ground plane, or external conductive elements spaced from the transducer. In a receiver, a signal-detector circuit may be responsive to a monitor signal representative of a received first radio-frequency electrical signal for generating a control signal that enables or disables an output from the receiver.

摘要： Docked devices communicate wirelessly and in close proximity using multiple transmitters of Extremely High-Frequency (EHF) signals of 30-300 GHz. The devices may not be precisely aligned when docked. Tolerance of misalignment is improved by adding barriers such as solid metal blocks or rows of metal-filled vias that have a spacing of less than one-quarter the EHF wavelength. The barriers reflect EHF radiation and prevent EHF radiation from penetrating the barrier. Barriers placed between adjacent transmitters and receivers block stray electromagnetic radiation from causing cross-talk. The barriers can be placed closer to the transmitters than to the receivers to allow for a wider area for reception, permitting a wider misalignment. EHF reflecting features such as ground planes spaced a quarter-wavelength apart may be added to an end of a substrate near a connecting edge to act as a barrier and reflect electromagnetic radiation back toward an intended receiver.

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.

摘要： 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.

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： An EHF receiver that determines an initial slicing voltage level and dynamically adjusts the slicing voltage level and/or amplifier gain levels to account for characteristics of the received EHF electromagnetic data signal. The architecture includes an amplifier, detector, adaptive signal slicer, and controller. The detector includes a main detector and replica detector that convert the received EHF electromagnetic data signal into a baseband signal and a reference signal. The controller uses the baseband signal and reference signal to determine an initial slicing voltage level, and dynamically adjust the slicing voltage level and the gain settings of the amplifier to compensate for changing signal conditions.

摘要： 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.
