  • Publication number: 20190138097
    Abstract: An operator control apparatus, in particular for a motor vehicle, having an operating surface for manual action by an element, particularly the finger of a human hand. A sensor interacts with the operating surface such that the sensor generates a signal when the element approaches the operating surface and/or when the operating surface is touched by the element and/or when pressure is applied to the operating surface by the element. The signal is used for switching and/or triggering a function in the style of a switching signal. The actuator is operatively connected to the operating surface, such that a haptic event is producible for the operating surface by means of actuation of the actuator. The actuator is driven electrically and operable by a PWM (pulse width modulation) actuation signal, such that the operating surface is movable in a preselectable manner within a preselectable displacement and/or time.

  • Patent number: 10071606
    Abstract: A sensor housing for mounting in a vehicle wheel, preferably a motor vehicle wheel and preferably on an inside of a tire of the wheel, is provided. The sensor housing includes a base surface for securing the sensor housing in the inner chamber of a wheel, a receiving area having a recess for receiving a sensor, and a predetermined breaking point for breaking open the receiving area and thus for releasing the sensor from the receiving area, preferably in a manner that prevents reuse of the sensor housing. A sensor arrangement including the sensor housing and a sensor received therein is also provided.

  • Publication number: 20180186088
    Abstract: The invention relates to a hand-guided device (10) for setting a setting element (12) in a component. The device comprises a handle (14) for holding the device, a carriage (34), which can be moved in relation to the handle and which bears a rotatably supported drive shaft (46), at one end of which a holder for the setting element is formed, a force accumulator (44), which is arranged between the handle and the carriage and which serves to store a defined advancing force, with which the force limiter can be loaded by means of a relative motion between the handle and the carriage, and a force limiter (64) for limiting the advancing force stored in the force accumulator. The force accumulator is designed to apply the stored advancing force to the setting element by means of the carriage. The invention further relates to a method for manually setting a setting element by means of said device.

  • Patent number: 9024742
    Abstract: A warning strategy determines in a mutually separate manner the different effects that may occur in a tire and allows the increments and their priority in the display or indication for the driver to be evaluated in a mutually separate manner. This strategy occurs in connection with a sensor which can transmit at least the outside temperature and, preferably, also the barometric pressure to an evaluation device for detecting tire inflation pressure and tire temperature. As a result, in addition to an air loss monitoring function, the load capacity of the tire can also be evaluated at least as a function of the outside temperature. The evaluation device receives further input signals, such as the vehicle velocity, the tire contact area and/or the vehicle load, whereby also a dynamic tire stress can be taken into account as an indication or display for the driver.

  • Patent number: 9019094
    Abstract: A method is provided for real-time monitoring of tire pressure, wherein the pressure value determined by use of a pressure sensor in the tire is transmitted by an electronic wheel device, without the use of a trigger transmitter fixed on the vehicle, by radio, in short transmission intervals, to a monitoring device installed in the vehicle, only if, at least when the vehicle is not moving, the value is outside a prespecified normal range. When the vehicle is not moving, the electronic wheel device transmits a signal suitable for a system monitoring function, at certain time intervals and, using the same time frame or a whole-number fraction or multiple thereof, carries out a measurement of the tire pressure. The signal has a short transmission duration on the order of 25 ?s to 500 ?s.

  • Patent number: 8959990
    Abstract: An arrangement of a tire pressure sensor unit on the inner wall of the tread of a vehicle tire in a retaining device for the sensor unit is provided. The retaining device is connected to the inner wall, wherein a sealing compound is applied to the inner wall, or in the case of a retaining device having a closed bottom section which is connected to the inner wall, the sealing compound is applied to the bottom section facing the sensor unit. In the event that a foreign object punctures the inner wall, or punctures the inner wall and the bottom section, the sealing compound prevents at least a short-term loss of pressure caused by the hole resulting therefrom in that the sealing compound at least almost tightly seals the hole.
