Patent number: 7930112Abstract: In a method of evaluating measured values for recognizing defect conditions due to material fatigue on aircraft parts, strain sensors (6) are applied on the critical locations of an aircraft (1) and measured values of outputs of the strain sensors are detected at different loading conditions, amplified and stored through several measuring circuits. An evaluating apparatus (9) derives, signals or indicates a material fatigue by comparison of current measured values with previous measured values. The critical aircraft parts (1) are impinged on with prescribed loading conditions by loading elements (3). The strain effect caused thereby is detected by measuring circuits. The evaluating apparatus (9) forms, for at least each loading condition and each measuring circuit, an allocated reference value and a permissible limit value range. If current measured values exceed the limit value range, this represents a material fatigue manifestation.Type: GrantFiled: April 19, 2006Date of Patent: April 19, 2011Assignee: Hottinger Baldwin Messtechnik GmbHInventor: Johannes Mattes

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

Patent number: 6380842Abstract: An electronic key for use with a vehicle locking system controls at least one of a door locking feature and an ignition lock feature on the vehicle. The electronic key has a transmitter/receiver for transmitting at least one coded operating signal generated by the electronic key and transmitted from the electronic key to the locking system to activate at least one function of the locking system upon positive evaluation of the transmitted operating signal by the locking system. Actuating members are provided on the key and operated by the user to cause the transmitter/receiver to transmit the coded operating signal, and the activating elements are also adapted for the user to enter an individual code.Type: GrantFiled: June 18, 1998Date of Patent: April 30, 2002Assignee: Marquardt GmbHInventors: Johannes Mattes, Karl Müller
