Abstract: A device for emitting and receiving electromagnetic radiation, in which different antennas are used for the emitting and receiving, a first antenna or first group being used for the transmission in a first polarization form, a second antenna or second group being used for the transmission in a second polarization form, and a third antenna or third group being used for receiving the reflected electromagnetic radiation that was emitted by the first antenna or first group and by the second antenna or second group. The device may be fixed in place on a motor vehicle and used for object detection within the framework of a distance and speed control or a collision avoidance, and the polarimetric information obtained from the different receiving levels during the propagation of the two differently polarized electromagnetic waves via different propagation paths is able to be used for ascertaining a weather-related road condition.

Abstract: A laser scanner that includes a transmission path and a reception path that is spatially separate from the transmission path, at least in areas. In the laser scanner, the transmission path and the reception path meet on opposite sides of an angularly movable deflection mirror of the laser scanner. An angular position of the deflection mirror in the transmission path defines a scan angle of a laser light of the laser scanner, and the angular position in the reception path compensates for an incidence angle of a reflection of the laser light.

Abstract: A user station for a serial bus system. The user station includes a receiver for receiving a signal from a bus of the bus system, and a device for evaluating the reception signal that is output by the receiver. The receiver generates a digital reception signal from the signal received from the bus and to output the signal to the device at a terminal. The device evaluates the digital reception signal with regard to a predetermined communication protocol that establishes when a predetermined communication phase, which indicates a subsequent transfer of useful data in a message, begins and ends. The device reverses the data flow of the digital reception signal to the receiver at the terminal for a time period of at least one bit if the evaluation of the device shows that data at that time are being received from the bus in the predetermined communication phase.

Abstract: A wiper actuating assembly configured to actuate a windshield wiper arm includes an actuator and a linkage that connects the actuator to the wiper arm. Links of the linkage are joined by ball joints. The ball joints each include a ball stud and a ball socket. The ball portion of the ball stud has an annular ball groove that receives a retaining portion that protrudes inward from the inner surface of the ball socket. The ball groove and retaining portion cooperate to prevent withdrawal of the ball stud from the socket housing.

The method includes mounting a sensor unit for detecting the pressure status value at a carrier substrate, fastening a frame to the carrier substrate, the frame including a fastening surface, a contact surface oriented opposite the fastening surface and an inner surface defining an opening and extending between the fastening surface and the contact surface, the frame being situated at the carrier substrate in such a way that the fastening surface faces the carrier substrate and the inner surface surrounds the sensor unit, and filling the opening of the frame with a filling material for forming an elastic pressure coupling layer. A pressure detecting unit for a measuring device for measuring a pressure status value of a plant specimen is also described.
Abstract: A method for driving a vehicle on an opposite lane in a controlled manner includes detecting, with a surroundings sensor system, surroundings of the vehicle and receiving, with a control device, measurement data of the surroundings sensor system. The method includes identifying at least one course of a road, and at least one course of at least one road user in the surroundings based on the received measurement data and planning a trajectory of the vehicle within the at least one course of a road. The method further includes identifying a section of the road wherein when driving on the section of road the opposite lane is cut across by the vehicle, and determining a first stop position for the vehicle prior to entering the identified section of road. The method then checks whether the opposite lane can be driven on in the identified section.

Abstract: A method for ascertaining a depth information image for an input image. The input image is processed using a convolutional neural network, which includes multiple layers that sequentially process the input image, and each converts an input feature map into an output feature map. At least one of the layers is a depth map layer, the depth information image being ascertained as a function of a depth map layer. In the depth map layer, an input feature map of the depth map layer is convoluted with multiple scaling filters to obtain respective scaling maps, the multiple scaling maps are compared pixel by pixel to generate a respective output feature map in which each pixel corresponds to a corresponding pixel from a selected one of the scaling maps.

Abstract: A method for acquiring the surrounding environment of a motor vehicle. The motor vehicle has at least one ultrasound sensor. The ultrasound sensor includes an ultrasound transducer for sending, the ultrasound sensor receiving acoustic environmental signals, in particular audible environmental signals, in that the ultrasound sensor is controlled in its evaluation in such a way that sound waves having frequencies below a resonant frequency of the ultrasound transducer, in particular audible sound waves, of an environmental signal are acquired and evaluated. Environmental signals are understood as acoustic signals that are not produced by the ultrasound transducer itself, but rather by an external sound source that in particular differs from the motor vehicle. This can be for example the siren of a rescue vehicle or emergency vehicle, or the horn of some other motor vehicle.
