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 scalable, high-bandwidth connectivity architecture for portable storage devices and memory modules may utilize EHF communication link chip packages mounted in various two-dimensional and three-dimensional configurations on planar surfaces such as printed circuit boards. Multiple electromagnetic communication links between devices distributed on major faces of card-like devices may be provided with respectively aligned pairs of communication units on each device. Adjacent communication units on a printed circuit board may transmit or receive electromagnetic radiation having different polarization, such as linear or elliptical polarization. Power and communication between communication devices may both be provided wirelessly.

摘要： “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.

摘要： An extremely high frequency (EHF) protocol converter may include a transducer, an EHF communication circuit, a protocol conversion circuit, and a circuit port. The transducer may be configured to convert between an electromagnetic EHF data signal and an electrical EHF signal. The EHF communication circuit may be configured to convert between a baseband data signal and the electrical EHF signal. The protocol conversion circuit may be adapted to convert between the baseband data signal having data formatted according to a first data protocol associated with a first external device and a second baseband data signal having data formatted according to a second data protocol associated with a second external device. The second data protocol may be different from the first data protocol. The circuit port may conduct the second baseband data signal to the second external device.

摘要： A computing device includes an integrated unit having a plurality of functional components, and an extremely high frequency (EHF) communication unit operatively coupled to the integrated unit. The EHF communication unit includes a transducer configured to transmit and receive EHF electromagnetic signals, and convert between electrical signals and electromagnetic signals. The computing device includes a transceiver operatively coupled to the transducer. The EHF communication unit may enable at least one of the functional components of the computing device to be supplemented by a functional component of an external computing device.

摘要： 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.

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： 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： 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.
