Patent number: 10771346Abstract: A method monitors a data transmission network having a plurality of devices connected to one another over fixedly prescribed signal transmission paths, for anomalies. One of the devices is a master device that has a counter and a trigger apparatus, by which a prescribed signal feature of a signal is acquired, and upon the acquisition, a master counter state corresponding thereto is read. The method provides for an evaluation apparatus to determine, under predetermined conditions, a setpoint value of at least one network-specific parameter defined by a physical property of the network, before an actual value of the network-specific parameter is determined from a difference between the master counter state and a further counter state, and an anomaly is indicated if a predetermined deviation criterion between the actual value and the setpoint value is met.Type: GrantFiled: March 22, 2017Date of Patent: September 8, 2020Assignee: Conti Temic microelectronic GmbHInventors: Uli Joos, Florian Gerster, Lorenz Lieder

Patent number: 8508259Abstract: A method for driving a non-linear load element. On account of the non-linear interrelationship between the voltage and the current at the load element and the related non-linear dependence of the power loss on the quantities “voltage” and “current”, an adjustment of the switching speed only on the basis of the power loss in the switching element cannot be carried out with non-linear load elements without being confronted with undesirable switching losses and related electromagnetic noise fields. Therefore, the load current currently flowing in the load element is picked up in addition to the currently determined power loss in the switching element, and the switching speed of the switching element is controlled in dependence on the determined power loss and on the current picked up. The switching speed can be optimally adjusted when driving the non-linear load elements by means of PWM.Type: GrantFiled: August 23, 2008Date of Patent: August 13, 2013Assignee: Conti Temic microelectronic GmbHInventors: Uli Joos, Jochen Zwick, Josef Schnell, Christian Voss

Patent number: 8093833Abstract: Disclosed is for controlling a light source by pulse width modulation of a supply voltage. The supply voltage, or a parameter dependent thereon, is measured and the pulse width is controlled as function of the measured value. The supply voltage or parameter is measured at least twice during the pulse and may be cyclically measured. The pulse width of the current or a subsequent pulse is matched to the recorded value of the supply voltage or the parameter. A total value is generated from all of the measured values and compared with a given value and the pulse width of subsequent pulses are matched as function of the difference between the total value and the given value.Type: GrantFiled: July 14, 2005Date of Patent: January 10, 2012Assignee: Conit Temic Microelectronic GmbHInventors: Uli Joos, Christian Voss, Josef Schnell, Jochen Zwick

Patent number: 8035363Abstract: A procedure for triggering a load element using an electronic switch element is presented, in which voltage on the load element is controlled with a maximum specified increase. The increase does not remain constant, but is controlled via the switching procedure in dependence on the effectively occurring power loss or a value which is dependant on it (Ua/Ubat), preferably in several phases, whereby preferably at the beginning and the end of the switch-over procedure in the phase where the output voltage changes, the increase is selected as being low relative to the increase in the middle phase, since as a result, the power loss is only insignificantly raised, yet the high-frequency interferences can be noticeably dampened.Type: GrantFiled: December 10, 2004Date of Patent: October 11, 2011Assignee: Conti Temic Microelectronic, GmbHInventors: Uli Joos, Armin Lenk

Patent number: 7977817Abstract: Disclosed is a method for pulse width modulated control of a plurality of load elements, particularly during supply of the load elements from a common supply system in motor vehicles. The load elements are controlled in a time staggered manner with respect to one another, more particularly in a phase staggered manner within a common pulse width. Switch loads and high frequency interferences in the supply lines and the corresponding emissions can thus be reduced. The invention also discloses a circuit arrangement in which a corresponding phase staggered control is achieved with only one counter.Type: GrantFiled: December 10, 2004Date of Patent: July 12, 2011Assignee: Conti Temic Microelectronic, GmbHInventors: Uli Joos, Josef Schnell
