  • ELECTRONIC DEROTATION OF PICTURE-IN-PICTURE IMAGERY
    Publication number: 20210295471
    Abstract: Electronically derotating a picture-in-picture video source can be used to independently derotate a secondary video source separate a primary video source. A method of electronically derotating a picture-in-picture image are described herein, the method comprising processing a first image having a first image primary axis; processing a second image having a second image primary axis; derotating the second image around the second image primary axis to align the second image primary axis substantially parallel with the first image primary axis; and displaying the first image and the second image on a display.

  • Resolver to digital conversion apparatus and method
    Patent number: 10256836
    Abstract: A resolver to digital converter is provided and includes first and second inputs to receive signals from a resolver and an output to provide an estimated angle of a rotor. The sine component signal is multiplied by the cosine of the estimated angle and the cosine component signal is multiplied by the sine of the estimated angle, and a difference between them is calculated to provide an error measurement. The estimated angle is updated by the error measurement.
