Title: Hdtv up converter
Inventor: LE DINH CHON TAM
IPC: H04N7/01
Filed: 1999-04-01
Granted: 2005-08-16
Abstract: An electronic apparatus for converting a standard video signal having 59.94 fields per second into an HDTV video signal having 60.00 fields per second, by adding a number of video fields into each sequence of 1000 video fields. The apparatus detects the best moment for adding the new video field, so that the human eye does not perceive an abrupt change in the video image, by detecting the best motion conditions which occurs either when the image motion is high or very low. For adding the new video field, the apparatus uses an interpolation technique for creating two interpolated video fields which are inserted in place of one existing video field which is deleted. The apparatus also comprises a de-interlacer module for deinterlacing the 60 Hz video image, by using an advanced interpolation technique for calculating the missing video lines. The proposed technique involves directional interpolations of the missing lines pixels in various directions and selection of the best interpolation direction for the creation of each pixel of the missing video lines. The corresponding de-interlacer apparatus comprises a novel edge direction detector which performs the mentionned interpolations in all interpolating directions and then selects the best direction for performing the interpolation for each interpolated pixel, based on the quality of the performed interpolations.

Granted: 2008-09-09
Abstract: A mass transfer column is provided with a liquid distributor that distributes liquid to an underlying mass transfer bed containing one or more random, grid or structured packing elements. The liquid distributor includes a plurality of elongated troughs that are spaced apart and extend across the column. A plurality of liquid discharge holes are positioned in side walls of the trough and are located in one or more preselected planes that are preferably spaced above a floor of the trough. Splash baffles are spaced outwardly from the trough side walls and include upper portions that are positioned to receive liquid exiting the troughs through the discharge holes. Lower portions of the splash baffles form a constricted discharge outlet in a plane below the trough for delivering liquid from the splash baffles to the underlying mass transfer bed. The liquid discharge holes in one of the trough side walls are offset from those in the other trough side wall to provide a uniform distribution of liquid to the discharge outlet. The splash baffles are vertically adjustable and are intended to be supported on the upper surface of the mass transfer bed so that the discharged liquid is delivered directly to the mass transfer bed, thereby reducing the opportunity for the falling liquid to become entrained in a vapor stream flowing upwardly through teh mass transfer bed. The liquid exiting through the discharge outlet preferably forms a curtain-like flow that blocks or impedes vapor entry upwardly into the discharge outlet. Any vapor that enters the discharge area is able to vent upwardly through the open spacing between the baffles and the associated troughs at a reduced velocity, thereby reducing the opportunity for liquid entrainment. The open spacing also permits any overflow of liquid from the troughs to be captured by the splash baffles for downward flow along the inner faces of the splash baffles.
