The protective shield is made of a conductive material, and is electrically and mechanically bonded to the exterior metal surface of the vehicle. The protective shield includes a cavity for accommodating the antenna, and at least one waveguide aperture extends through the protective shield and into the cavity.

The invention relates to a vehicle assembly including a radar sensor configured to emit radar waves over a range of wavelengths, a luminous module. The luminous module including a sub-layer and a layer of patterns forming a sub-wavelength structured dielectric element with a repetition period of the patterns that is less than a quarter of a wavelength of the range, with the total thickness of the luminous module is equal to m times a wavelength of the range, the whole being divided by twice the equivalent refractive index of the sub-layer and of the layer of patterns, times the cosine of a refracted angle corresponding to an angle of incidence of the radar waves, where m is an integer.

A vehicle communication apparatus includes a plurality of remote units (RUs) configured to transmit signals to a mobile communication network and to receive signals from the mobile communication network, and a central unit (CU) configured to provide data based on the signals received through the plurality of remote units to one or more devices located in a vehicle. The plurality of remote units includes an array antenna attached to a body of the vehicle.

A battery system has a cell including a container, a substrate mounted to the container, and circuitry on the substrate. The substrate defines antennas, a microprocessor, switches, and a transceiver. The microprocessor sequentially activates the switches to respectively connect the transceiver to the antennas to establish a location relative to a transmitter, and prevents communications with the transmitter responsive to the location falling outside a predefined range.

Systems of an electrical vehicle and the operations thereof are provided that use identifiers and sensed power source parameters to determine whether a rule, such as a warranty or licensing requirement, has been violated.

An antenna overlay system includes antenna hardware, a communication link, and electronic circuitry disposed on a substrate. The communication link couples the electronic circuitry to the antenna hardware. During operation, the electronic circuitry in communication with the antenna hardware is operable to control transmission and reception of wireless signals in a wireless region. An adhesive layer disposed on a surface of the substrate couples the substrate to an object such as a window. In one arrangement, the window is a low-E glass windowpane that substantially attenuates wireless signals from being received by communication equipment in a building in which the windowpane is installed. The antenna overlay system provides enhanced RF signal reception and transmission.

A radio frequency antenna with a two-piece sealing ferrule. The antenna includes a center antenna and an outer tube surrounding the center antenna. A mounting nut surrounds and is slidable relative to the outer tube. An outer ferrule surrounds and is slidable relative to the outer tube. An inner ferrule that is separate from the outer ferrule surrounds and is fixed to the outer tube. A mating nut is secured to the mounting nut. The threading of the mounting nut and the mating nut together results in the wedging between the inner and outer ferrules which results in the exertion of a first compressive force by the inner ferrule against the outer tube for sealing the inner ferrule and the outer tube and the exertion of a second compressive force of the inner ferrule against the mating nut for sealing the inner ferrule and the mating nut.

An in-vehicle light apparatus for monitoring a region in a first direction outside a vehicle, including: a lamp unit including a light source and a reflector; a radar unit including a circuit board disposed such that a board surface extends substantially along the horizontal direction on a lower side or an upper side of the lamp unit and a plurality of antenna elements disposed in the hoard surface of the circuit hoard to transmit an electromagnetic wave in the first direction; and the plurality of the antenna elements are arranged in an array on the first direction side relative to the reflector in plan view, and an array direction of the plurality of antenna elements is a direction intersecting the first direction and non-parallel to an extending direction of an end portion on the side of the first direction of the reflector in plan view.

A communication system is disclosed. The system can include a first communication unit including a first antenna, a second communication unit including a second antenna and a dielectric waveguide cable, and a rotary joint configured to enable the first unit to rotate with respect to the second unit about an axis of rotation of the system. The dielectric waveguide cable can extend from the second antenna to the rotary joint, where a proximal end of the cable can be coupled to the second antenna and a distal end of the cable can be affixed to the second unit at a location bordering a space defined by the rotary joint. The first and second units can be configured to engage in two-way communication with each other. An axis of the distal end of the cable can be substantially aligned with the axis of rotation of the system.
