Patent number: 9983235Abstract: The present invention relates to a method and a device for measuring currents or magnetic fields using at least one Hall sensor, which is operated with spinning current technology. In addition to first sample values for calculating a spinning current measurement value (6), second sample values are formed from the digitally converted sensor signals (1) of the Hall sensor in the method. The second sample values are formed over shorter periods of time (9) and are corrected with an offset, which is calculated from the spinning current measurement value (6) and the first sample values. In addition to the precise spinning current measurement value (6), fast offset-corrected measurement values (10) of the magnetic field or current are obtained using the method and the associated device, without elaborate calibration or additional analog circuitry expenses.Type: GrantFiled: February 26, 2013Date of Patent: May 29, 2018Assignee: FRAUNHOFER-GESELLSCHAFT ZUR FOERDERUNG DER ANGEWANDTEN FORSCHUNG EV.Inventors: Michael Hackner, Hans-Peter Hohe, Markus Sand

Patent number: 8849547Abstract: In a common rail system having two electrically controlled actuating elements, e.g., a metering unit at the input side of a high-pressure pump and a pressure regulating valve on the common rail, different fuel delivery quantities are able to be set in the common rail system while the vehicle is stationary, independent of the current engine load, by controlling operating points via one of the actuating elements and subsequently regulating the other actuating element. Control currents of the actuating elements correspond to the operating points. These control currents, or differences of control currents, are compared to target values to enable an evaluation of the common rail system.Type: GrantFiled: March 14, 2012Date of Patent: September 30, 2014Assignee: Robert Bosch GmbHInventors: Michael Hackner, Stefan Hoerenberg

Patent number: 8830365Abstract: A circuit for processing an analog signal having a time sequence of discrete signal levels, each of which lies in a time interval and represents an information-bearing segment of the interval while the rest of the time interval is a non-information-bearing segment, comprises a transistor in emitter-follower or source-follower configuration, a high emitter or source resistance or, instead, a high-ohm constant current source, and a device for applying a voltage supply, as well as a switch which is connected between the emitter and a reference potential to prevent a current from flowing via the high-ohm resistance or the high-ohm voltage source for charge reversal of an output capacitance of the circuit in one direction, whereas for charge reversal in the other direction the dynamic current boosting effect of the transistor is exploited. This results in a fast emitter-follower or source-follower circuit which is particularly suitable as the output stage for image sensors.Type: GrantFiled: May 26, 2011Date of Patent: September 9, 2014Assignee: Fraunhofer-Gesellschaft zur Foerderung der Angewandten Forschung E.V.Inventors: Thomas Bellingrath, Michael Hackner
