A flexible radar support for absorbing vibration deviation comprises a support base and a support top cover that are engaged with each other in an interlocking manner. A housing space for arranging a radar is formed between the support base and the support top cover. The support base includes: a centrally arranged base center, and a base edge circumferentially arranged around the base center. The base edge and the base center are connected through four flexible structures that form U-shaped cantilever beams protruding towards the support top cover. With the flexible radar support provided, and with the design of U-shaped flexible structures, where an automobile body vibrates at a large amplitude, the flexible radar support can still absorb swaying in the up and down, and left and right directions during the course of driving, thereby reducing the impact of the automobile body's vibrations on the detection precision of a radar.

A vehicular radar sensor includes an emission part for emitting an electromagnetic wave and a reception part for receiving an electromagnetic wave, and a waveguide including a restriction portion, which is open at front and rear surfaces thereof so as to allow an electromagnetic wave to be transmitted therethrough and which is fixed at the open rear surface thereof to the antenna and extends outwards from a front end of the antenna, and a flaring portion, which extends outwards with an increasing cross-sectional area from a front end of the restriction portion.

The present disclosure relates to an apparatus and method for determining failure of a vehicle radar apparatus. In the vehicle radar apparatus, it is possible to set the normal range of the failure determination signal characteristic for each temperature by measuring the signal characteristic value at 2 or more temperature values for each transmission channel or each reception channel the normal operation state, and to determine the failure of the radar apparatus based on whether the representative value of the measured signal characteristic measured at the time of determination is within the normal range of the failure determination signal characteristic.

A radar apparatus is provided with transmitting means, receiving means, target detection means, azimuth detection means and a cover member. The cover member has a first face and a second face. The first face and second face are not parallel to one another. At least one of the first face and second face is a curved surface which is curved along azimuth detection directions of the azimuth detection means, such as to provide a large phase difference between incoming waves that are received by a plurality of antenna elements and are from within a range of large angular values in the azimuth detection directions of the azimuth detection means.

A sensor assembly for use in association with non-integrated, ground-based collision avoidance systems for aircraft, including (a) a sensor; and (b) a frame sub-assembly, wherein the sensor is releasably securable to the frame sub-assembly.

A decorative component for a vehicle includes a decorative body portion having millimeter wave transmittance and a heating sheet. The decorative body portion is configured to decorate the vehicle by being attached to part of a vehicle on a leading side in a transmitting direction of millimeter waves from a millimeter wave radar device. The heating sheet includes a plastic sheet and a wire-shaped heater provided on the plastic sheet. At least a main portion of the heating sheet is provided integrally with the decorative body portion. The thickness in the front-rear direction is set uniform in at least a transmittance area of millimeter waves in the decorative body portion and the heating sheet.

A luminaire includes a radio wave sensor and a luminaire body. The luminaire body includes a first plate to be attached to a building surface and a second plate facing each other forming an internal space. The luminaire body holds the radio wave sensor between the first plate and the second plate. The radio wave sensor includes an antenna for transmitting and receiving the radio waves. The luminaire body includes an opening and a limiter. The opening is formed in the second plate to allow radio waves transmitted from the antenna to exit to an outside of the luminaire body. The limiter is provided between the antenna and the opening to limit a radiation area of the radio waves transmitted from the antenna.

A detection apparatus, a method for manufacturing a detection apparatus, and a terminal including a detection apparatus are disclosed. The detection apparatus integrally designs a vehicle skin and a radar device, to eliminate an installation process of a radar device and auxiliary mechanical parts in a vehicle equipment production line, and reduce management of installed accessories. In addition, a radome of a radar and a vehicle skin are combined into one, which is equivalent to eliminating a radome of a conventional radar, thereby obtaining better millimeter-wave propagation performance.

A roof module for forming a vehicle roof on a motor vehicle may have a panel component whose outer surface at least partially forms a roof skin of the vehicle roof; at least one environment sensor configured to send and/or receive electromagnetic signals for detecting the vehicle environment and disposed at least partially below the roof skin formed by the panel component; and a cooling feature configured to discharge waste heat emitted by the environment sensor and/or externally introduced heat from the environment sensor. The cooling feature may have at least one cooling channel in which at least two cooling fans are disposed, the cooling fans being connected to at least one controller of the cooling feature.

A sensor assembly includes a housing including an outlet. The sensor assembly includes a sensor window, the sensor window fixed relative to the housing, and the outlet aimed across the sensor window. The sensor assembly includes a flap rotatably coupled to the housing at the outlet. The sensor assembly a deflector covering the flap, the flap disposed between the outlet and the deflector and rotatable toward and away from the deflector.
