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. Power may be provided to the adapter from the source device, and by the adapter to the destination device.

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: 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.

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: 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.

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: 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.

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.

摘要: 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.
