An antenna array apparatus includes: first antenna elements arranged to form a first radiation pattern with a recessed portion at the center of the first radiation pattern; and second antenna elements arranged to form a second radiation pattern with a convex portion at the center of the second radiation pattern.

A vehicle reinforcement assembly includes a detector and a reinforcement member. The detector is configured to be housed in an interior compartment of a vehicle. The reinforcement member is configured to be housed in the interior compartment at a location adjacent to the detector. The reinforcement member has a vehicle forward facing end that extends closer to a vehicle front end than the detector extends to the vehicle front end.

An apparatus for correcting an error of a radar sensor for a vehicle and a method thereof can correct a target measurement error of the radar sensor installed inside a bumper of the vehicle based on target information obtained from a camera image. The apparatus includes: a radar sensor that is installed inside a bumper of the vehicle to detect a target, a camera that photographs a surrounding image of the vehicle, and a controller that corrects a target detection error of the radar sensor based on target information obtained from an image photographed by the camera.

An antenna array apparatus includes: first antenna elements arranged to form a first radiation pattern with a recessed portion at the center of the first radiation pattern; and second antenna elements arranged to form a second radiation pattern with a convex portion at the center of the second radiation pattern.

A non-contact object and/or gesture detection system includes at least one sensor configured to sense an object or motion within a field of view (FOV) using radio frequency radiation. Various sensor and brackets are provided which may allow a position and/or tilt of the sensor to be adjusted for controlling the FOV. A sensor housing includes a vent filter that breathable but impermeable to liquids. Various antenna designs are provided to provide desired FOV sizes and shapes, particularly for optimizing a radiation pattern that is relatively wide and shallow. A steerable antenna layout is also provided for controlling the location of the FOV without an adjustable bracket. A sensor housing including a projector mount for an icon projector is provided. A seal prevents debris from entering between the antenna and the bumper.

A system comprises a first phased array radar assembly configured to be attached to a vehicle. The first phased array radar assembly includes a first plurality of antennas arranged in an array and attached to a circuit board. The system also includes one or more circuits attached to the circuit board. Each of the one or more circuits includes transmitter circuitry communicatively coupled to a subset of the first plurality of antennas and receiver circuitry communicatively coupled to the subset of the first plurality of antennas.

Low-cost devices and methods for measuring radar transmission and/or reflectance of coated articles, as well as methods for forming coatings on articles are provided. An exemplary low-cost radar transmission and reflection measurement device includes a radar transmitter that emits a radar signal, a radar target to which the radar signal is directed, and a radar receiver that receives the radar signal. Further, the exemplary low-cost device includes a sample holder located between the radar transmitter and the radar target and between the radar target and the radar receiver. The sample holder receives a sample including a coating. The low-cost device also includes a controller connected to the radar transmitter and radar receiver. The controller measures a radar signal loss due to the coating.

A vehicle control system may include a controller that detects an object outside a vehicle, calculates an angle based on a ratio of a relative speed between the object and the vehicle to a speed of the vehicle, and updates a phase curve reflecting a phase distortion of an input signal based on the calculated angle.

The invention relates to a cover element having a housing of a film that is formed and moulded between a front plate and a carrier plate and is used to represent multidimensional structures, the carrier plate being connected on the rear side to a heating plate, characterized in that the housing consists of an annular housing base and an annular housing front, and a circuit-board ring having LEDs and plugs is installed in the housing base.

An antenna device includes a dielectric substrate, a ground plate arranged on a first surface of the dielectric substrate, an antenna part arranged on a second surface of the dielectric substrate, and a reflecting part. The reflecting part is arranged around the antenna part and has a plurality of conductor patches each functioning as a reflecting plate. The plurality of conductor patches form a plurality of blocks aligned along a predetermined block arrangement direction. The plurality of blocks are configured such that phases of reflected waves at an operating frequency are different for each of the blocks and phase differences of reflected waves between adjacent blocks are non-uniformly different for each of the adjacent blocks.
