摘要： A pylon mounting system with vibration isolation is provided. The system generally includes a housing that defines a first fluid chamber and a second fluid chamber, a fluid disposed within the fluid chambers; a piston assembly at least partially disposed within the housing, and a tuning passage defined by the piston assembly for providing fluid communication between the fluid chambers. The piston assembly has a first arm and a second arm, and each arm has a tubeform bearing for providing pitch and roll stiffness.

摘要： A system and method to improve the quality of reproduced images on a film to video transfer device by scanning extra lines to reduce vertical aliasing and performing vertical sample rate reduction to produce the correct number of video output lines High frequency noise is reduced as a result of the vertical sample rate reduction which produces a line filtering. More lines are scanned than normal and the distance between lines is reduced so that the larger number of lines covers the original film image area. This has the effect of increasing the sampling frequency in the vertical direction and therefore reducing aliasing. To provide the correct number of lines in the output of the film to video sample, rate reduction is performed. Sample rate reduction is performed by filtering multiple adjacent lines to remove any high frequency content that would be aliased at the lower rate. Lines are discarded in a predefined sequence that is a function of the fractional reduction rate.

摘要： A magnetic deflection amplifier implemented using a linear amplifier connected to a first side of a deflection coil and a three pole switch connected to a second side of the deflection coil. The three pole switch connects the coil to ground during the active scan and connects the coil to a positive or negative high voltage rail depending of the polarity of the retrace current resulting in fast retrace time and reduced voltage requirements on the linear amplifier.

摘要： Circuitry for selectively reducing noise which results from film granularity, circuitry imperfections and other sources of random signal degradation by averaging, non-recursively, between 2 and 9 frames of digitized video information. By such averaging, since the noise is random, it is filtered out leaving only the desired picture. The averaging is performed only on areas of the picture which are close in both amplitude and color in adjacent frames. In this connection, in cases where there is no motion or scene change between adjacent frames, the entire picture corresponding to such frames can be processed according to the present invention.
