A touch screen operator control and/or display device (), for a motor vehicle has a display element (). At least one graphics element () can be represented on the display element () by visible light radiation. A sensor () detects the representation of the graphics element (). The sensor () detects in particular, changes in brightness on the display element ().

Operator control and/or display device

A crank transmission having a crankshaft for connection to at least one foot or hand crank and at least one gear wheel driven by means of the crankshaft () is proposed. A coupling unit is provided between the crankshaft and the gear wheel. Under load, the coupling unit has at least temporarily an angular offset between a crank-side receiving region and an output region connected to the gear wheel for receiving and outputting the torque generated via the crank.

The invention relates to a measuring apparatus for measuring a measurement variable of a fluid, particularly a sensor, such as a pressure sensor or a displacement sensor. The measuring apparatus comprises a housing, a diaphragm arranged in and/or on the housing, and a resilient element formed in the manner of a leaf spring for restoring the diaphragm. A signal transmitter is operatively connected to the diaphragm and/or the resilient element, and a signal receiver cooperates with the signal transmitter. The resilient element is fastened on the housing at the edge of the resilient element, more specifically in particular only at parts of the edge.

Mechanical fluid sensor

The invention relates to a measuring apparatus for measuring a measurement variable of a fluid, in particular a sensor, such as a pressure sensor or a travel sensor. The measuring apparatus has a housing, a diaphragm which is arranged in and/or on the housing and an elastic element, which is designed in the manner of a leaf spring, for restoring the diaphragm. A signal transmitter is operatively connected to the diaphragm and/or to the elastic element, and a signal receiver interacts with the signal transmitter. Structures for providing reinforcement are arranged in the edge region and/or in the center of the elastic element.

Sensor

A process and a device are provided for ascertaining the rotation of a liquid spray arm for a domestic appliance. Lighting means serves as a light transmitter and a photoreceiver serves as a light receiver. The lighting means and the photoreceiver are assigned a light-conducting element. At a first location of the light-conducting element, at least some light emitted from the lighting means is coupled to a path so that the light is guided in the light-conducting element by total reflection. At a second location of the light-conducting element that spaced apart from the first location in the direction of propagation of the light, the light guided in the light-conducting element is coupled out of the path so that the light is received by the photoreceiver. The intensity of the light received by the photoreceiver is evaluated by an evaluation circuit with respect to the rotation of the spray arm.

A locking system for providing authorization to access and drive a motor vehicle has a first control device for unlocking and locking the car doors, the ignition lock, the steering wheel lock, etc. Additionally, the locking system has a second device, which is an electronic key or an identifier. The two devices have transmission means and/or receiving means for electromagnetic signals with frequencies &#x3bd; lying in a frequency band between two cut-off frequencies &#x3bd;a, &#x3bd;b. At least one of the signals, transmitted between the devices, is a coded operating signal for authenticating the second device. The actual frequency &#x3bd;i with which the transmission means of the second device is operated is stored in a storage means of the first device.

Locking system, in particular for a motor vehicle

A system for automatic access or driving authorization for a motor vehicle includes a first device in the form of a control device having at least two states for engaging and disengaging vehicle door locks, an immobilizer, or the like. An associated second device is provided in the form of an electronic key, an ID transmitter, a chip card or the like. Both devices have means for transmitting or receiving signals, including a coded operating signal for authenticating the second device, so that a change in the state of the first device can be implemented when the second device is authorized. Before the second device is first activated, it is in a sleep state in which operation-independent function is not permitted and energy consumption is reduced. During a first operator-dependent authentication, the second device is changed over from the sleep state into a standby state in which an operation-independent function is at least partially made possible.
