  • Patent number: 9279825
    Abstract: A MEMS-sensor structure comprising first means and second means coupled for double differential detection and positioned symmetrically to provide quantities for the double differential detection in a phase shift. If the sensor deforms, due to a specifically symmetric positioning of the first and second means, the effect of the displacement is at least partly eliminated.

  • Patent number: 8265810
    Abstract: A method for automatically controlling the speed of a ship, in which the engine speed (nMOT) is automatically controlled by a closed-loop engine speed control system as an inner closed-loop control system, the ship's speed (vS) is automatically controlled by a closed-loop ship's speed control system as an outer closed-loop control system, and the ship's set speed (vSL) is influenced as a reference input of the closed-loop ship's speed control system as a function of an external signal source. The ship's set speed (vSL) is corrected as a function of the underwater topography (TOPO).

  • Patent number: 7591201
    Abstract: A MEMS structure having a compensated resonating member is described. In an embodiment, a MEMS structure comprises a resonating member coupled to a substrate by an anchor. A dynamic mass-load is coupled with the resonating member. The dynamic mass-load is provided for compensating a change in frequency of the resonating member by altering the moment of inertia of the resonating member by way of a positional change relative to the anchor.

  • Patent number: 7021166
    Abstract: A booster actuator 10 may be positioned between the solenoid 12 and a valve 14, and increases the energy output from the solenoid to activate the valve. The booster actuator 10 may include a force input member 28 and a force output member 30 each linearly movable with respect to a body 20 from an initial position to an activated position. A coil spring 46 biases the input member to the initial input position, while a plurality of disk springs 48 bias the output member 30 to the activated output position. A plurality of linking members 32 each pivotable with respect to the body normally retain the force output member in the initial position, but upon movement of the input member to the activated position release the force output member in response to the disk springs.
