Patent number: 9267859Abstract: 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.Type: GrantFiled: May 29, 2013Date of Patent: February 23, 2016Assignee: Marquardt Mechatronik GmbHInventors: Dietmar Weisser, Markus Scheiter

Patent number: 7709781Abstract: 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.Type: GrantFiled: January 11, 2008Date of Patent: May 4, 2010Assignee: Marquardt GmbHInventors: Dietmar Weisser, Guido Schick, Heinrich Müller, Wolfgang Häussler, Michael Bessler

Patent number: 7667571Abstract: 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 ? lying in a frequency band between two cut-off frequencies ?a, ?b. At least one of the signals, transmitted between the devices, is a coded operating signal for authenticating the second device. The actual frequency ?i with which the transmission means of the second device is operated is stored in a storage means of the first device.Type: GrantFiled: August 17, 2005Date of Patent: February 23, 2010Assignee: Marquardt GmbHInventors: Karl Mueller, Johannes Mattes, Uwe Hipp, Dietmar Weisser, Michael Geber, Markus Ruther, Andreas Pohlmann, Matthias Reinhardt

Patent number: 6963794Abstract: 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.Type: GrantFiled: July 22, 2004Date of Patent: November 8, 2005Assignee: DaimlerChrysler AGInventors: Michael Geber, Uwe Hipp, Johannes Mattes, Karl Mueller, Andreas Pohlmann, Matthias Reinhardt, Markus Ruther, Dietmar Weisser
