A device for improving the transmission behavior of radar waves (λ) is disclosed, which includes a wall section where in a first location a first and a second surface are located at a first wall thickness distance (dw1) and in a second location the first surface and the second surface are located at a second wall thickness distance (dw2) and differing relative to each other by a first value (Δ1). An equilibration body mounted on the first surface of the wall section, such that in the first location a first body surface and a second surface are located at a first distance (de1) relative to each other and in the second location the first body surface and the second surface are located at a second distance (de2). The first distance (de1) and the second distance (de2) differ from each other by a second value (Δ2) such that second value (Δ2) is smaller than the first difference (Δ1). An external cladding component of a vehicle and vehicle including the device is also disclosed.

A LiDAR sensor (41) is configured to sense information of an outside of a vehicle. An ultrasonic sensor (42) is configured to sense information of the outside of the vehicle in a different manner from the LiDAR sensor (41). A first bracket (43) supports the LiDAR sensor (41) and the ultrasonic sensor (42). A first sensor actuator (44) is configured to adjust a sensing reference position of the LiDAR sensor (41) relative to the first bracket (43). A second sensor actuator (45) is configured to adjust a sensing reference position of the ultrasonic sensor (42) relative to first bracket (43). A first bracket actuator (46) is configured to adjust at least one of a position and a posture of the first bracket (43) relative to the vehicle.

A sensor lens assembly includes a cylindrical sensor body including a lower surface, a sensor lens surface, and a side surface extending between the lower surface and an outer edge of the sensor lens surface, a sensor enclosed within the cylindrical sensor body and adjacent to the sensor lens surface, and a nozzle configured to deliver a fluid near a center point of the sensor lens surface. The sensor lens surface is concave and rotates relative to the side surface of the cylindrical sensor body such that centrifugal force causes the fluid to form a film on the sensor lens surface that acts as a barrier, cushion, and particle collecting medium on the sensor lens surface.

A pressure compensation element includes a plastic part and a membrane, wherein the plastic part has an upper and an underside and at least one hole extending from the upper to the underside. At least one hole is formed in an offset manner and/or in that at least one bridge-type element is arranged on the upper or the underside of the plastic part, and extends over the at least one hole

The present invention relates to a sensor assembly configured to be mounted on a vehicle. The sensor assembly comprises a sensor; and a housing housing the sensor. The housing comprises an inclined front wall configured to face a main traveling direction (A) of the vehicle and a direction (B) away from the vehicle, a vehicle facing wall configured to face towards the vehicle, the vehicle facing wall comprising an air inlet, and a rear openings forming a viewing opening for the sensor, the rear opening being in fluid connection with the air inlet such that air entering the air inlet exits the housing through the rear opening.

A vehicle component integrates an environment detection sensor into a vehicle. The vehicle component is in the form of a plastic component and has a main body with a recess for receiving the environment detection sensor. Towards a visible side of the vehicle component, the recess is delimited by a cover portion which has a signal passage surface or a signal passage opening.

A vehicle lamp includes: a lamp housing; a lamp cover covering an opening of the lamp housing; an illumination unit disposed in a lamp chamber formed by the lamp housing and the lamp cover; a radar configured to acquire radar data indicating surroundings of a vehicle by emitting an electromagnetic wave outside the vehicle; and a concealing part that faces the radar to conceal the radar from the outside of the vehicle and is configured to let the electromagnetic wave emitted from the radar through. The concealing part is formed integrally with the lamp cover. A boundary between the concealing part and the lamp cover is out of a field of view of the radar.

A vehicle component includes an electromagnetic wave reflection portion that reflects an electromagnetic wave. The vehicle component is made of a dielectric. Thickness L.sub.2 of the electromagnetic wave reflection portion is set based on the following equation:

[00001]$L_2=\left(2n+1\right)\frac{\lambda g}{4}$

where n is an integer greater than or equal to 0 and λg is a wavelength of the electromagnetic wave in the dielectric.

A vehicle structure includes a body, a bracket provided on the body, a bumper cover attached to the bracket, and an object detection device attached to the bracket.

A high-frequency detection system (100) such as a terahertz camera is disclosed which includes a first detector array (102), a second detector array (104), and a polarizing plate (106). The polarizing plate is interposed between the detector arrays such that it passes and/or reflects radiation signals (110) from a source (108) to the detector arrays. A first radiation signal (112) having a first polarization is passed through the polarizing plate to the first detector array, and a second radiation signal (114) having a second polarization is reflected from the polarizing plate to the second detector array. Both radiation signals are from source (108), which can be one or more human beings emitting radiation towards the detection system. In some embodiments, the detector arrays (102, (104) may be joined. Each of the detector arrays comprises one or more input channels, such as feedhorns (116, 118, 120) which capture radiation from source (108) and pass the received signal into other portions of the system for subsequent processing. Input channels and local oscillator channels are aligned to one axis, and output channels are aligned to an axis perpendicular thereto. The system may further include a scanning mechanism (126). The detection systems described herein can use a heterodyne mixer. For instance, the array of feedhorns deliver incoming radiation via waveguides to a diode-based mixer with an intermediate frequency output to processing circuitry. System (100) can be used for the detection and identification of weapons, threats, illicit goods, and stolen items.
