Abstract: A sensor assembly of a vehicle. The sensor includes a control device, a multitude of sensors, each sensor having an individual sensor identifier, a data bus, which connects each sensor to the control device, and a supply line, which connects each sensor to the control device for a voltage supply. Each sensor has a shunt resistor. All shunt resistors are integrated in series into the supply line. Each sensor is developed to detect a voltage drop at its respective shunt resistor. The control device is developed to actuate each sensor with the aid of the individual sensor identifier and to assign an individual geographical address to each sensor based on the detected voltage drops along the supply line.

Abstract: A sensor, including at least one transducer for emitting signals and for receiving reflected echo signals, the transducer being set up to output an analog measuring signal, an analog-to-digital converter for converting the analog measuring signal into a digital measuring signal, an evaluation unit for evaluating the digital measuring signal, and a communication unit for transmitting a measuring result of the evaluation via a digital communication interface. The communication unit is equipped to receive a request for diagnostic data via the digital communication interface, and is also equipped to switch the sensor to diagnostic operation and to transmit requested diagnostic data via the digital communication interface. The communication unit is set up to communicate with at least two different data rates via the digital communication interface, a higher data rate being used for transmitting the diagnostic data than for transmitting the measuring result during normal operation of the sensor.

Abstract: An operating method for an ultrasound transceiver device, where the ultrasound transceiver device is alternately and, in particular alternatingly operated in a transmit mode and in a receive mode; subsequently to a transmit mode and/or prior to a receive mode, the ultrasound transceiver device is actively damped by the action of a sequence of counter control pulses; a phase position and/or a damping energy are/is iteratively determined or adapted via a training by a measure of the damping success at least temporarily assuming or approaching an at least locally optimal value.

Abstract: A method for heating an ultrasonic transducer, in which an interior of the ultrasonic transducer together with a diaphragm element is heated by thermal radiation of a component, the temperature of the diaphragm element being increased to a temperature above the freezing point. The heating is achieved by a component which in a first operating mode is used to implement a transmitting and/or receiving operation of the ultrasonic transducer, and in a second operating mode is operated in such a way that the component has an increased electrical power loss compared to the first operating mode.

Abstract: A surroundings-sensing device for emitting and/or receiving ultrasonic signals including an ultrasonic transducer, which includes at least one transducer element and at least one resonance body including a front body and a rear body, and including a diaphragm for sound transmission, which is coupled to an end face of the front body, the front body, the transducer element, and the rear body being separably connected to one another, and the front body being fastened on the diaphragm. Further described is a motor vehicle including a bumper, a side mirror, or a door section and at least one such surroundings-sensing device, the diaphragm of the surroundings-sensing device being formed by an outer skin of the bumper, the side mirror, or the door section and the ultrasonic transducer being situated concealed behind the outer skin.

Abstract: A method for acoustically sensing an area is described. An acoustic transmit pulse is transmitted into the area by an acoustic transducer and a received signal is acquired with the aid of the transducer, in order to receive the transmit pulse reflected back from the area. Within a post-pulse oscillation time of the transducer, which directly follows the emission of the transmit pulse, the actual phase response of the received signal is determined. In the event the actual phase response deviates from a predefined setpoint phase response, an object is detected within the area. Also described is a device for acoustically sensing an area, which is designed to carry out the method.

Abstract: A removable insole for footwear is disclosed which is used for heating the wearer's feet. The insole includes a recessed area for containing a heat source. The improved insole comprises an upper layer, a padding layer, a lower layer, and a cover plate. The cover plate covers the recessed area, thereby forming a cavity for containing a heat source, and extends to the tip of the toe portion. The lower layer has a plurality of recessed channels formed therein which communicate with the recessed area to facilitate the flow of air to and from the heat source. The cover layer is attached to the lower layer in only a few discrete places to facilitate the flow of air to and from the heat source. The insole and/or cover plate have at least one cutout on the periphery of one of the sides in the area of the recessed area which allows for easy insertion and removal of the heat source.
