  • System and method for determining geo location of a target using a cone coordinate system
    Patent number: 10670689
    Abstract: A method for determining geo-position of a target by an aircraft includes: receiving navigation data related to the aircraft including aircraft attitude information; receiving multilateration information related to the target including an angle to the target; calculating an axis for a cone fixed to the aircraft, based on the received aircraft attitude information; calculating a central angle for the cone from the received angle to the target; generating two vectors orthogonal to the cone axis; calculating a cone model from the axis, the central angle and the two vectors; and intersecting the cone model with an earth model to obtain a LEP curve, wherein the LEP curve is used to determine the geo position of the target.

  • Structure and method for film grain noise reduction
    Patent number: 6067125
    Abstract: A video signal is both spatially and temporally filtered. The output video signal is temporally noise reduced in portions of the image which exhibits little or no motion, and is spatially noise reduced in portions where motion exists. This approach is particularly applicable to reducing film grain noise in video material that originates from images on photographic films, since film grain noise is more correlated spatially than temporally.
