Patent number: 7088160Abstract: A circuit arrangement for regulating a parameter (e.g., duty cycle) of an electrical signal, generated by a circuit component. The regulating device includes a first integrator, which is supplied with the output signal from the circuit component, and a second integrator, which is supplied with the output signal from the first integrator. The second integrator has an operational amplifier having an inverting input, a noninverting input and an output, and the output is fed back to the inverting input via a feedback path. The inverting input receives the output signal from the first integrator. The noninverting input receives a reference signal. The output of the operational amplifier is fed back to the inverting input via a series circuit including a capacitor and a resistor. The output of the second operational amplifier provides an output signal from the regulating device, which is supplied to the circuit component as a controlled variable.Type: GrantFiled: July 22, 2004Date of Patent: August 8, 2006Assignee: Infineon Technologies AGInventors: Torsten Harms, Harald Doppke, Detlev Theil, Stefan van Waasen

Patent number: 7076854Abstract: A toothed or splined shaft having an external toothing is pushed with clearance into an internal toothing of a hub, tooth to space, and the external toothing of the shaft is pressed together with the internal toothing of the hub. In the push-in position of the shaft, the latter is deformed plastically out of a cavity of the shaft in a radial circumferential widening operation and, so as to provide freedom from clearance between the spaces of the external toothing of the shaft and the internal toothing of the hub, the internal toothing engaging into the external toothing is pressed against the hub in such a way that the hub is deformed elastically and a press fit between the shaft and the hub is produced.Type: GrantFiled: May 3, 2001Date of Patent: July 18, 2006Assignee: DaimlerChrysler AGInventors: Torsten Harms, Juergen Knuedel

Publication number: 20060001493Abstract: An amplifier circuit for converting the current signal from an optical receiving element into a voltage signal. The amplifier circuit includes a transimpedance amplifier having a differential amplifier and a feedback resistor, a first adjustable resistor which is connected in parallel with the feedback resistor and whose resistance value is defined by a first control signal, and a series circuit connected in parallel with the feedback resistor. The series circuit includes a first capacitor and a second adjustable resistor, whose resistance value is defined by a second control signal. The two adjustable resistors are preferably formed as MOS resistors and have the same control signal applied to them. The amplifier circuit permits the provision of a high dynamic range during the operation of a transimpedance amplifier.Type: ApplicationFiled: February 25, 2005Publication date: January 5, 2006Applicant: Infineon Technologies Fiber Optics GmbHInventors: Torsten Harms, Stefan Waasen

Publication number: 20050135817Abstract: A control device with a switchable bandwidth including: an integrating element with a first capacitance, which is charged and discharged by at least one current; at least one second capacitance, which can be connected in parallel with the first capacitance via a first switch; and at least one voltage follower, via which the voltage present at the first capacitance can be fed to the second capacitance. In this case, the first switch is open if the voltage present at the first capacitance is fed to the second capacitance by means of the voltage follower. The first switch is closed if the second capacitance is connected in parallel with the first capacitance. The invention enables a further capacitance to be supplementarily connected without a disturbance signal arising.Type: ApplicationFiled: April 2, 2004Publication date: June 23, 2005Applicant: Infineon Technologies AGInventors: Torsten Harms, Stefan van Waasen

Publication number: 20040034981Abstract: The invention relates to a method for making a shaft/hub connection. For this purpose, a toothed or splined shaft having an external toothing is pushed with clearance into an internal toothing of a hub, tooth to space, and the external toothing of the shaft is pressed together with the internal toothing of the hub. In order to make it possible in a simple reproducible way to make a shaft/hub connection which optimally satisfies the requirements of dynamic loads, it is proposed that, in the push-in position of the shaft, the latter is deformed plastically out of a cavity of the shaft in a radial circumferential widening operation and, so as to provide freedom from clearance between the spaces of the external toothing of the shaft and the internal toothing of the hub, the said internal toothing engaging into the said external toothing, is pressed against the hub in such a way that the hub is deformed elastically and a press fit between the shaft and the hub is produced.Type: ApplicationFiled: June 27, 2003Publication date: February 26, 2004Inventors: Torsten Harms, Juergen Knuedel

Publication number: 20040020249Abstract: An overload safeguard on a joining connection and a method for producing the overload safeguard are provided. The joining connection comprises an outer joining part having a through-opening and a cylindrical, inner joining part which is acted upon by torque, protrudes through the through-opening in the outer joining part and is frictionally connected to the latter. A countertorque of equal magnitude to the torque of the inner joining part acts on the outer joining part in such a manner that when a torque value corresponding to the maximum permissible frictional force is exceeded, the frictional connection is released and the inner joining part slips in the connection. The inner joining part forms a press fit with the outer joining part and, with its outer circumference, bears against the inner circumference of the through-opening in the outer joining part with a pre-stressing force corresponding to the torque value.Type: ApplicationFiled: August 15, 2003Publication date: February 5, 2004Inventors: Jens Battermann, Stephan Gaertner, Torsten Harms, Joerg Haertel, Axel Hebenstreit, Torsten Kirchner, Holger Kittler, Hanno Lox
