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 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: Circuit connectors for establishing EHF communication include a receiver configured to receive a transmitted EHF electromagnetic signal, and an output circuit coupled to the receiver. The output circuit has two states of operation that correspond to enabling a signal output and disabling the signal output. The output circuit is also configured to change its state of operation responsive to a state of a control signal, and a controller is coupled to the receiver and configured to produce the control signal. The control signal has two states that correspond to a first condition when the received signal exceeds a first threshold and a second condition when the received signal is less than a second threshold.

Abstract: “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.

Abstract: Contactless extremely high frequency (EHF) signal directing and blocking structures are disclosed herein. The EHF signal directing structures may focus EHF signal energy along a desired EHF signal pathway. The EHF signal blocking structures may minimize signal propagation through substrates such as circuit boards. Focusing EHF signal energy and selectively blocking the EHF signal energy can minimize or eliminate crosstalk and enhance data transmission speed and integrity.

Abstract: 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.

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: Shielded extremely high frequency (EHF) connector assemblies are disclosed herein. In some embodiments, a first extremely high frequency (EHF) shielded connector assembly configured to be coupled with a second EHF shielded connector assembly. The first EHF connector assembly can include a first EHF communication unit operative to contactlessly communicate EHF signals with a second EHF communication unit included in the second EHF shielded connector assembly. The first connector can include a connector interface that includes a configuration to interface with a respective connector interface of the second EHF shield connector assembly, and several different material compositions that, in conjunction with the configuration, provide shielding to prevent or substantially reduce EHF signal leakage when the first EHF assembly connector is coupled to the second EHF assembly connector and the first EHF communication unit is contactlessly communicating EHF signals with the second EHF communication unit.
