Patents by Inventor Antonius C. J. Stavenuiter

Antonius C. J. Stavenuiter has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6621245
    Abstract: A calculation system for calculating the control signals which are designed to perform a frequency-dependent weighting of the angular velocity signals and the angular position signals. The angular velocity indicators are preferably used for stabilization in a high frequency band while the angular position indicators are suitable for stabilization in a low frequency band. A further calculation system which is designed to perform the frequency-dependent weighting such that the control signals for frequencies below a certain frequency are substantially determined by the angular position signals and the control signals for higher frequencies are substantially determined by the angular velocity signals.

  • Publication number: 20020105298
    Abstract: The invention concerns an enhanced system for the stabilization of an object with reference to a moving platform. The invention is in particular suitable for the stabilization of a shipborne optical search sensor. The system comprises a stabilization platform and a regulator According to the invention, the regulator calculates control signals for the stabilization platform on the basis of a combination of absolute ship's angular position signals and signals produced by rate gyro systems mounted on the stabilization platform. Thus, disturbances caused by flexure of the ship's structure and the stabilization platform are effectively compensated for. Said signals are preferably combined by frequency-dependent weighting.
