Patent number: 11988826Abstract: A method for controlling a drive apparatus (18) of a micro-oscillation mirror (16), a control device (28) and a deflector mirror apparatus (14) are described. In the method, at least one actuation signal (20) is generated, and the drive apparatus (18) is actuated therewith in such a way that it drives the micro-oscillation mirror (16) in an oscillating fashion, At least one position signal (26) which characterizes the deflection (22) of the micro-oscillation mirror (16) is sensed. The at least one actuation signal (20) is closed-loop controlled on the basis of the at least one position signal (26) in such a way that the micro-oscillation mirror (16) is driven at its resonant frequency, The amplitude of the at least one position signal (26) is continuously compared with at least one threshold value (38a, 38b, 38c). At least one time interval (42a, 42b, 42c) between at least two passes of the at least one position signal (26) through at least one threshold value (38a, 38b, 38c) is determined.Type: GrantFiled: June 4, 2019Date of Patent: May 21, 2024Assignee: VALEO SCHALTER UND SENSOREN GMBHInventors: Jürgen Nies, Jochen Schenk, Michael Kleiser

Patent number: 7284345Abstract: The milling apparatus (1) has a bucket with a receiving chamber and has a milling unit with a milling rotor (14). The receiving chamber has a receiving opening (4) and is embodied as a bucket (2). On the bottom of the bucket (2), a through opening (19) is provided, which leads into a milling chamber (12). The milling rotor (14) can move material both into the receiving chamber and out of it again. To achieve both modes of operation, in a first embodiment a drive mechanism rotating in a predetermined direction (D) is provided; a beating arm (16) is associated with the first mode of operation, and a further beating arm (24) is associated with the second mode of operation. In another embodiment, which makes do with a single beating arm (16), the milling unit (54) can be operated in two different working positions via a turner. The positions differ from one another by a 180° rotation about a vertical axis that is perpendicular to the axis of rotation of the milling rotor (14).Type: GrantFiled: December 6, 2002Date of Patent: October 23, 2007Inventor: Jürgen Schenk

Patent number: 7182204Abstract: A method and an apparatus for processing mixtures of material which contain a coarse component (3) and a predominantly cohesive fine component (4). Both the mixture of material (2) and an added material (5) are delivered in continuous streams of material (11, 23) to a homogenizing and separating device (12). The homogenizing and separating device (12) serves to mix the added material (5) and the mixture of material (2) uniformly with one another, so as to put the fine component (4) of the mixture of material (2) into a state such that the fine components (4) can be separated from the coarse component (3). As a result of the continuous delivery of the mixture of material (2) and added material (5) to the homogenizing and separating device (12), intimate mixing of the added material (5) and fine component (4) is achieved so that the separation of the coarse component and fine component can take place directly in the same device.Type: GrantFiled: March 8, 2002Date of Patent: February 27, 2007Inventor: Jürgen Schenk

Patent number: 6953166Abstract: An apparatus suitable for treating mineral material, particularly excavated earth, has two rollers that rotate in opposite directions, on which a plurality of elements is disposed, the elements serving to transport and reduce the material in case its particle size is too large. Elements that are designed to exert a notch effect onto particle sizes larger than a minimum size are provided for reducing brittle and large-particle components of the mineral material, in particular. The reduction by means of the notch effect has been proven to save energy and subject machines to low wear. The elements that produce the notch effect can also reduce wood (tree stumps).Type: GrantFiled: November 29, 2001Date of Patent: October 11, 2005Inventor: Hans Jürgen Schenk

Patent number: 6550312Abstract: A method for determining the air/fuel ratio in an internal combustion engine combustion chamber having at least two ignition plugs spaced apart from one another. Ion-current measurement is carried out during successive operating cycles, wherein a first ignition plug is operated as an ion-current sensor and does not release ignition energy. The time of arrival at the first ignition plug of a flame front formed at the ignition point of a second ignition plug, is detected. The detected time of arrival of the flame front, the ignition point and the ignition-plug spacing are used to determine the speed of the flame and, from this, the air/fuel ratio is determined as a function of the speed and/or load of the internal combustion engine.Type: GrantFiled: March 10, 2000Date of Patent: April 22, 2003Assignee: DaimlerChrysler AGInventors: Peter Hohner, Jürgen Schenk, Hartung Wilstermann

Patent number: 6283093Abstract: A method for determining the ignition angle for an internal combustion engine with adaptive knocking control, in which the occurrence of knocking is reduced by a controlled adjustment of the ignition angle in the retarded direction. The current values for the adjustment in the retarded direction are stored in a characteristic diagram in an operating parameter-dependent fashion. An average adjustment in the retarded direction is determined from these characteristic diagram values, and both a correction ignition angle and a control range limitation for the knocking control are determined therefrom. The fuel quality and ambient influences are automatically sensed with reference to a learned RON level and are also used to reduce the amount of energy expended to control engine knocking.Type: GrantFiled: December 18, 1998Date of Patent: September 4, 2001Assignees: DaimlerChrysler AG, Robert Bosch GmbHInventors: Peter Lautenschuetz, Juergen Schenk, Hans-Joachim Volkmann, Stephan Hartmann

Patent number: 6230546Abstract: A method and an apparatus for detecting knocking combustion in an internal combustion engine, by evaluating the ionic current signal sensed in the combustion chamber, is especially adapted to correct or compensate the ionic current signal for longterm variations arising therein, for example due to variations in the composition of the fuel as a result of contamination with metallic components or the like. Thereby, erroneous knock recognition is prevented. To achieve this, a frequency-filtered time-sampled knocking component integral of the ionic current signal generated in the present combustion cycle is multiplied by a correction value determined from at least one integral value of the ionic current signal generated during at least one prior combustion cycle.Type: GrantFiled: December 14, 1998Date of Patent: May 15, 2001Assignees: Temic Telefunken microelectronic GmbH, DaimlerChrysler AGInventors: Hartung Wilstermann, Peter Hohner, Peter Bertelshofer, Juergen Schenk
