  • Patent number: 11485343
    Abstract: A sensor arrangement for a braking system of a vehicle is disclosed comprising a connection interface, a control unit, and a sensor. The sensor has an external interface with electrical contacts via which the sensor is connected to the control unit. The control unit is connected to and supplied with power via the connection interface and exchanges data with a higher-level unit via the connection interface. The sensor is provided power via the electrical contact points and provides electrical output signals via the electrical contact points. A first contact point provides a first electrical output signal and is connected to the connection interface via a first switching element such that the first contact point is connected to the connection interface when the first switching element is in the deenergized state and is disconnected from the connection interface when the first switching element is in the energized state.

  • Patent number: 10998798
    Abstract: A drive assembly has a housing block, on which there is arranged an electrical machine. The latter has a working shaft mounted in a shaft bore of the housing block and the rotational position of which is detected by a sensor device formed by a signal transmitter and a signal receiver comprising evaluation electronics. The shaft bore is closed by a cover, which is arranged between signal transmitter and signal receiver. The cover is formed in one piece with an electronics housing of the signal receiver. A centering device for the signal receiver is formed on the housing block on the electronics housing. The disclosed drive assembly simplifies the construction, functional testing and mounting of the signal receiver and at the same time improves the protection thereof against damaging environmental influences.

  • Patent number: 9140621
    Abstract: An arrangement for the direct contacting of contact mechanism has a first contact mechanism arranged on a contact carrier and a second contact mechanism. The second contact mechanism acts with a predetermined contact force on the first contact mechanism. The contact carrier includes a plastic injection premolding of galvanizable plastic and a nongalvanizable plastic. The galvanizable plastic has a predetermined resilient behavior and the first contact mechanism is formed by a metal layer having predetermined dimensions. The first contact mechanism can be applied onto the galvanizable plastic in a galvanic process. The resilient behavior of the galvanizable plastic and the dimensions of the metal layer form, under the predetermined contact force, a microdepression configured to guide the second contact mechanism in the first contact mechanism.

  • Patent number: 5867884
    Abstract: A device for measuring the mass of a flowing medium having a temperature-dependent sensor element, which is inserted flush in a recess of a sensor carrier and is retained therein by means of an adhesive. The sensor carrier is made by bending a thin metal strip and has two elements, a frame element and a retaining element, which together form a recess, into which the sensor element is inserted flush and glued by means of an adhesive to a plateau-like protuberance of a bottom face of the retaining element. The sensor carrier is intended for a device for measuring the mass of a flowing medium for measuring the flow rate or mass of the air aspirated by internal combustion engines.

  • Patent number: 5723784
    Abstract: The invention proposes a device for measuring the mass of a flowing medium, in particular the mass of air aspirated by internal combustion engines. The device has a platelike sensor element which is accommodated in a recess of a sensor carrier, and which with a sensor region that has at least one measuring resistor is exposed to the flowing medium in order to measure its mass. The sensor element is accommodated essentially flush in the recess and is retained in the recess by being glued to a bottom face in the recess. The bottom face of the recess of the sensor carrier has a troughlike indentation, which extends at least partially along the circumference of the sensor element outside the sensor region that has the at least one measuring resistor. The device according to the invention is intended to measure the mass of a flowing medium, in particular for measuring the mass of air aspirated by internal combustion engines.

  • Patent number: 5712425
    Abstract: A device for measuring the mass of a flowing medium by use of a temperature-dependent measuring resistor bathed by the flowing medium and accommodated in a measuring channel. The device has a flow obstacle, embodied in the form of a trip edge, upstream of the measuring element in the region of an inlet opening of the measuring channel, so as to create a chronologically and spatially stable separation zone in the region of the trip edge, thereby preventing chronologically and spatially unstable separation zones and makes it possible to attain a reduction in measuring signal noise. The invention is contemplated for measuring the mass of a flowing medium, especially for measuring the aspirated air mass in internal combustion engines.
