  • Patent number: 10865716
    Abstract: A camshaft adjuster for adjusting the phase angle between a crankshaft and a camshaft of an internal combustion engine comprises an actuator, in particular, an electric motor, and an adjustment module, which comprises a drive element, which can be driven by the crankshaft, and an output element, which can be rotated relative to the drive element to a limited extent and which is provided to be securely coupled to the camshaft, wherein a signal generator, which is arranged so as to be fixed in position on the internal combustion engine and which has an inductance, is inductively coupled to a measurement circuit, which is integrated into the adjustment module and which has at least one resonant circuit component having electrical properties that depend on the said phase angle.

  • Patent number: 10804824
    Abstract: A circuit, comprising a plurality of phase windings in an electric motor, an inverter configured to excite the phase windings by a sequence of voltage pulses including a plurality of successive voltage pulses that a current can be set in each of the phase windings, wherein the voltage pulses are selected in such a manner that a positive and a negative current are produced in all the phase windings during the voltage pulses, a current sensor for measuring a peak value for the current being set during a duration of each voltage pulse in each phase winding, and an evaluation circuit connected to the current sensor, wherein the evaluation circuit is configured to determine the voltage pulse in the voltage pulse sequence during a duration of which peak current value having a greatest magnitude was measured.

  • Patent number: 9912534
    Abstract: A computer system includes a server computer including a processor, a main memory and a system management chip, a management station that manages server profiles and selects a server profile from server profiles and associates it with the server computer, and at least one data network via which the server computer and the management station are coupled to interchange data, wherein the system management chip of the server computer is set so that, when the system management chip activates, it sends an inquiry regarding a server profile associated by the management station to the management station, so that, if a management connection can be set to the management station, it configures a component of the server computer by using a network identifier transmitted by the management station, and to otherwise prevent starting of the server computer with a network identifier transmitted by the management station previously.

  • Patent number: 6589103
    Abstract: The invention relates to a device for the finishing treatment of shaft workpieces, in particular crankshafts and camshafts. The device comprises a carrier, at least one jaw for exerting contact pressure on the workpiece, and a linear guide for guiding the jaw. The linear guide is supported by a transverse guide to form a cross guiding system which follows the rotational motion of the workpiece by revolving around its axis of rotation. The transverse guide contains a main carriage guided on the carrier. The main carriage is radially aligned with respect to the axis of rotation of the workpiece. The main carriage has a fork-shaped head facing towards the side of the workpiece. A guide rail for the linear guide is chucked between the between the legs of the fork-like head.
