Embodiments discussed herein refer to electric vehicle charging ports having integrated contactless communication units (CCUs). The electric vehicle charging ports include male and female connector assemblies that can be coupled together in a manner that enables consistent and reliable operation of contactless communications and power transfer. The connector integrates power and alignment such that when two connector assemblies are coupled together, power connections are made in combination with establishing contactless communications links between counterpart CCUs in both connector assemblies. The fixed alignment of the connector assemblies ensures that contactless communication channels, spanning between the connector assemblies, are aligned to enable consistent and reliable operation of contactless communications. The CCUs, which conduct contactless communications, may be integrated in the connector assemblies at fixed positions that enable CCUs of one connector assembly to be aligned with CCUs of another connector assembly when they are coupled together.

Charging ports with integrated contactless communication units

Embodiments discussed herein refer to connectors that enable two structures or devices to be coupled together in a manner that enables consistent and reliable operation of contactless communications and power transfer. The connector integrates power and alignment such that when two connectors are coupled together the power connections are also responsible for connector alignment. The connector alignment ensures that contactless communication channels, spanning between the connectors, are aligned to enable consistent and reliable operation of contactless communications.

Conduit structures for redirecting extremely high frequency (EHF) signals are disclosed herein. The conduit structures discussed herein are designed to re-direct EHF or RF signal energy from a first signal path to a second signal path. The conduit structures according to embodiments discussed herein can re-direct the RF signal energy while simultaneously adhering to specified signaling characteristic of the RF signal and minimizing stray RF signal radiation within a device to support device-to-device contactless communications.

Side launch contactless signal conduit structures

Conduit structures for guiding extremely high frequency (EHF) signals are disclosed herein. The conduit structures can include EHF containment channels that define EHF signal pathways through which EHF signal energy is directed. The conduit structures can minimize or eliminate crosstalk among adjacent paths within a device and across devices. Launch structures that interface with waveguides are also disclosed herein. Launch structures can control the EHF interface impedance between a contactless communication unit and the waveguide. Waveguide structures discussed herein are designed to provide maximum bandwidth with minimal jitter over a desired distance.

Hinge assemblies that serve as conduits for guiding extremely high frequency (EHF) signals are disclosed herein. The hinge assembly can contain EHF signal energy as data is transmitted from one structure to the other and the hinge assembly can also include a one or more waveguides that define EHF signal pathways through which EHF signal energy is directed. Each hinge assembly may serve as a conduit structure for each coupled pair of contactless communication units (CCUs), and multiple hinge assemblies may be used as separate conduit structures each of several coupled pairs of contactless communication unit.

Methods, systems, and apparatus for EM isolation structures. One of the apparatus includes a communication module, the communication module including: a printed circuit board; a plurality of integrated circuit packages, each integrated circuit package including at least one transmitter, receiver, or transceiver; and one or more metallic blocking structures configured to at least partially encircle a corresponding one of the plurality of integrated circuit packages, wherein each metallic blocking structure is configured to reduce signal leakage from the corresponding integrated circuit package.

Signal isolation structures for EM communication

A method uses temperature measurements for a print head and an imaging member to identify a distance between a print head and an imaging member. The method determines whether the print head at the print position is too close to the imaging member to identify the gap distance without damage to the print head. Then, if the print head is not too close, the print head is heated to quantify the heat sink effect of the imaging member on the print head. This effect is related to a heat transfer function that identifies the gap distance between the imaging member and the print head.

Method for measuring a gap between an intermediate imaging member and a print head using thermal characteristics

A method uses temperature measurements for a print head and an imaging member to identify a distance between a print head and an imaging member and a heat transfer function. The method includes heating an imaging member to a predetermined imaging member temperature, activating a heat source to heat a print head to a predetermined print head temperature while the print head is at a non-imaging position with reference to the imaging member, moving the heated print head to a print position with reference to the imaging member, the print position being closer to the imaging member than the non-imaging position, deactivating the heat source, measuring a first temperature for the print head in response to a first time period expiring, and identifying a distance between the print head in the print position and the imaging member from the temperature measured for the print head, the predetermined imaging member temperature, and a difference between the predetermined print head temperature and the temperature measured for the print head.
