Title: Method to form symmetric search windows for bidirectional half pel motion estimation
Inventor: SVEC RONALD S
IPC: H04N7/32
Filed: 1996-06-28
Granted: 1999-08-11
Abstract: A method for forming a bidirectionally coded picture from two reference pictures. The method starts by taking a memory fetch of each reference picture, finding best match macroblocks at the full pixel boundaries thereof, and interpolating the full pixel boundary macroblocks to form bi-directional macroblocks calculating half pixel reference picture data therefrom. Excess pixels are dropped from the best match macroblocks to make the best mach macroblocks symmetric in size, shape, and orientation. This may be accomplished by setting edge detectors to indicate excess pixels. The excess pixels correspond t pixels rendering the best match macroblocks different in size, shape or orientation.

Abstract: A user definable set of event rollup relationships are maintained as a configuration element. Transitive closure of event rollup relationships is checked at the time of specification to detect cycles and prevent runtime errors. When an event to be processed is detected, the event is compared to defined rollup relationships and queued events to determined if the detected event may be rolled up into at least one queued event or vice versa. If the detected event may be rolled up into a queued event, the detected event is not queued. When any of the queued event may be rolled up into the detected event, the queued events are deleted if processing has not already begun.

Title: Method for recovering EDTA from waste water containing complex of EDTA and metal
Inventor: LEU CHING-HUEI
IPC: C02F1/46
Filed: 1998-12-17
Granted: 2000-11-21
Abstract: The present invention provides a method for recovering EDTA from waste water containing complex of EDTA and metal. The waste water containing complex of EDTA and metal is subjected to electrolysis in the cathode chamber of the membrane electrolysis vessel, thereby depositing heavy metals on the cathode plate to remove heavy metals, and leaving the complex of EDTA and non-heavy metals in the cathode solution. Subsequently, the cathode solution is adjusted to a pH of 0.7 to 2.5 to form EDTA crystal, which is finally collected. The present invention can be utilized in recovering EDTA, which is used to extract metal in solid contaminants. Since the recovery of EDTA can reach higher than 95%, the extraction cost can be greatly decreased.
