Abstract: An ultrasonic welding device includes a sonotrode with a sonotrode surface, a lateral slide with a lateral slide surface, a touching element with a touching surface and an insertion chamber for inserting joining parts. The insertion chamber is defined in a first axial direction (y) on a first side by the sonotrode surface and in a second axial direction (x) on a second side by the lateral slide surface and on a third side opposing the second side by the touching surface. Furthermore, the ultrasonic welding device includes a first receiving element with a first stop edge and a second receiving element with a second stop edge. The first receiving element and the second receiving element are arranged to be movable in relation to each other between a starting position and an end position.

Abstract: A sensor module as well as a method for manufacturing a sensor module for determining a property of a fluid, in particular for measuring air quality, comprises a printed circuit board, at least one sensor on the printed circuit board for measuring a parameter of the surrounding air and a housing for the printed circuit board. A part of the printed circuit board protrudes from an opening in the housing (10), wherein the at least one sensor (21, 22) is located on a front side of the protruding part of the printed circuit board. In addition, at least the front side of the protruding part of the printed circuit board, with the exception of a recess for the at least one sensor, is encapsulated with a filling compound. The sensor module can be used in an interior or an air duct of motor vehicles or buildings. In one embodiment, the sensor module measures temperature, relative humidity and gas concentration in a fluid, especially in the surrounding air.

Abstract: The invention relates to a sensor module (1) for measuring at least one measurand, comprising: a housing (2) having a flow duct (23) with an air inlet (21) and an air outlet (22), the housing (2) enclosing an interior (20) of the housing (2); a circuit board (4) arranged in the interior (20); at least one sensor (3) which is arranged on the circuit board (4) and is designed to measure at least one measurand of an air flow (L) conducted past the sensor (3); a terminal (5) arranged on the circuit board (4) for making electrical contact with the sensor module (1); and a fan (6), which has a motor (60) and a rotor (61) which can be rotated about an axis of rotation (z) by means of the motor (60), the motor (60) being electrically conductively connected to the circuit board (4), and the fan (6) being designed to generate an air flow (L) in the flow duct (23) between the air inlet (21) and the air outlet (22) such that the air flow (L) flows past the sensor (3) and, in the region of the air inlet (21), flows in a f
