Patent number: 7888952Abstract: A circuit arrangement is provided for balancing a resistance circuit, which has a field-effect transistor as a controllable resistor and a control circuit, by which the field-effect transistor can be controlled with a gate-source voltage so that there is a resistance between a drain electrode and a source electrode of the field-effect transistor in a predefinable ratio to a reference resistor. In a balancing operation mode, a reference current can be set by the drain-source path of the field-effect transistor and by the reference resistor, which depends on a differential voltage between a voltage drop, caused by the reference current at the reference resistor and a voltage drop, caused by the reference current, at the drain-source path of the field-effect transistor.Type: GrantFiled: November 17, 2008Date of Patent: February 15, 2011Assignee: Atmel Automotive GmbHInventor: Reiner Franke

Patent number: 6237431Abstract: Apparatus for testing non-rotationally symmetrical hollow bodies for defects includes a conveyor for continuously conveying the hollow body through a test region past a detector for producing measurement values characterising the nature of the respective hollow bodies being tested, in dependence on the angle of rotation of the hollow body. An evaluator device compares the measurement values to predetermined values to decide whether the respective hollow body being tested suffers from defects. The conveyor has a receiving device which is fitted over the respective hollow body to embrace it. The receiving device with the hollow body is rotated through a predetermined angular amount while the hollow body is being transported past the detector device. The receiving device is removed from the hollow body again in the region where the conveyor conveys the hollow bodies out of the test region.Type: GrantFiled: October 28, 1998Date of Patent: May 29, 2001Assignee: Reiner Franke GmbH & Co.
