A radar antenna includes a plurality of horns in the annular space of a munition nose cone. The horns are disposed near the exterior surface of the nose cone. In a further aspect, the nose cone may be injection molded or additively manufactured so that the horns are embedded a known distance from the exterior surface. In a further aspect, the horns placed in either a transmit mode or a receive mode so as to maintain a minimum special separation between transmitting horns and receiving horns.

A composite pane for a vehicle with an outer pane and an inner pane that are joined to one another via a thermoplastic intermediate layer and the composite pane is provided for separation of a vehicle interior for occupants from an external environment, wherein at least one radar sensor is integrated into the thermoplastic intermediate layer and is designed and arranged such that the radar sensor emits radar beams into the vehicle interior and receives reflected radar beams, and the radar sensor is connected to an evaluation unit for determining movement and/or presence of persons or animals in the vehicle interior.

The present disclosure comprises an evaporative cooling assembly (200) for cooling an apparatus (220), and a method for cooling an apparatus (220). The evaporative cooling assembly comprises a refrigerant tank (202), the refrigerant tank (202) containing refrigerant (204). The apparatus also comprises a first evaporator (210) configured to be positioned proximal to the apparatus (220), and a second evaporator (216) positioned to cool the refrigerant tank (202). Each of the first evaporator (210) and the second evaporator (216) are in fluid communication with the refrigerant tank (202), and the second evaporator (216) is positioned downstream of the first evaporator (210). The method for cooling a heated apparatus (220) comprises passing a refrigerant (204) from a refrigerant tank (202) to a first evaporator (210), which is located proximal to the apparatus (220). At least part of the refrigerant is evaporated, and then passed to a second evaporator (216), which is positioned to cool the refrigerant tank (202).

A packaged integrated circuit (IC) includes an IC die having first and second external contacts and a package substrate. The IC die is attached to the package substrate which includes a balun in a first metal layer. The balun is connected to the first and second external contacts of the IC die and to a first external contact of the package substrate. The first and second external contacts of the IC die communicate a differential signal with the package substrate, and the first external contact of the package substrate communicates a single-ended signal corresponding to the differential signal. Alternatively, the balun is connected to an external contact of the IC die and to first and second external contacts of the package substrate, in which the external contact of the IC die communicates a single-ended signal and the first and second external contacts of the package substrate communicate a differential signal.

Sensor module for mounting on a motor vehicle panel component having a sensor housing, at least one environment sensor, at least part of which is disposed in the sensor housing, and which is configured to send and/or receive electromagnetic signals to thus detect a vehicle environment, and a kinematic system having a drive configured to move the sensor housing from a retracted position into at least one deployed position. The kinematic system is configured to move the sensor housing into a first deployed position, which activates the at least one environment sensor to detect the vehicle environment in a portion of its field of view, and to move the sensor housing into a second deployed position, which activates the at least one environment sensor to detect the vehicle environment in its entire field of view.

A method can include attaching a sensor device contained in a sensor structure to a body; sensing motion of the body with at least one motion capacitive sensor of the sensor device that senses a capacitance change resulting from a difference in orientation of the motion capacitive sensor and a surface of the body. If motion of the body is not sensed with the motion capacitive sensor, sensor readings can be acquired with a biophysical sensor that emits signals into a portion of the body below the sensor structure, and generate data for a feature of the body with the sensor readings. If motion of the body is not sensed with the motion capacitive sensor, data for the feature of the body is not generated. Related devices and systems are also disclosed.

The techniques of this disclosure describe a scalable cascading automotive radar system that generates a common oscillator signal enabling consecutive chirps to be output more quickly and precisely than any previous cascading automotive radar system, thereby reducing phase noise and improving performance. The scalable cascading automotive radar system combines a respective LO signal output from at least two primary transceivers to distribute the combined signals as a common oscillator signal to be input to all the transceivers of the radar system. Thus, settling time and resetting times that otherwise occur between chirps generated by other automotive radar systems are reduced because the common oscillator signal is no longer constrained to a single LO signal from a single primary transceiver.

A decorative molded article transmits a radio wave handled by a radar device as a wireless device and illuminates a specific portion by a light irradiated from a light emitting device. A first reflective layer is formed to have a first opening portion in a back surface of a molded body, reflects light incident from the first opening portion, and transmits the millimeter wave. A first coloring unit transmits the millimeter wave and colors the light incident from the first opening portion to generate a first colored light. A shielding layer of a decorative sheet is fixedly secured to a translucent film, transmits the millimeter wave, and shields the first colored light. The shielding layer has a second opening portion arranged in the specific portion of the translucent film to take out the first colored light from the molded body to a front of a front surface.

A door handle assembly for integration into a vehicle door including a support element coupled to the vehicle door, a handle element arranged on the support element, and a radar apparatus arranged on the support element or on or in the handle element and configured to emit radar radiation and to receive reflected radar radiation.

A radar sensor for a motor vehicle, in particular a passenger car, is disclosed. The radar sensor has a control unit, an antenna arrangement, and a reflector device for reflecting transmitted radar signals from the antenna arrangement into a measurement region and radar signals, which are to be received by the antenna arrangement from the measurement region. The reflector device has a parabolic reflector. The control unit is designed to change the measurement region by changing the radiation characteristic and/or the reception characteristic, in particular by beamsteering and/or beamforming, during control of the antenna arrangement such that various reflection regions of the reflector device that correspond to different measuring regions are used.
