Title: Two section economizer damper asembly providing improved air mixing
Inventor: WEISBECKER RICHARD T
IPC: F24F13/04
Filed: 1993-10-13
Granted: 1995-10-10
Abstract: A two section damper assembly and method of use is disclosed for avoiding stratification of cooled air in an air conditioning system.  The damper assembly is especially adapted for use in variable air volume air conditioning systems that include an economizer.  During the economizer mode of operation, the building in which the air conditioning system is installed is cooled at least partially with outside air as opposed to cooling solely by mechanical means and the volume of air that is required may be relatively low.  The variable two section damper assembly ensures that an adequate volume of cooling air is taken in and that there is adequate velocity of the outside air and return air to ensure mixing of the outside air with the return air in order to avoid the stratification of the supply air that can occur.  The damper assembly is variable in the size of the opened area and in the direction that the individual vanes of the damper assembly are set.

Title: A data compression system including successive approximation quantizer
Inventor: SHAPIRO JEROME MARK
IPC: G06T9/00
Filed: 1993-01-22
Granted: 2004-11-02
Abstract: A data processing system augments compression of non-zero values of significant coefficients by coding entries of a significance map independently of coding the values of significant non-zexo coefficients.       A dedicated symbol,(from 1038) represents a zerotree structure encompassing a related association of insignificant coefficients within the tree structure. The zero-tree; symbol represents that a coefficient is a root of a zerotree if, at a threshold (T), the coefficient (from 1002) and all of its descendants that have been found to be insignificant at larger thresholds have magnitudes less than threshold T. The zerotree structure is disclosed in the context of a pyramid-type image subband processor together with successive refinement quantization and entropy coding to facilitate data compression.

Title: Esophageal stent and delivery tool
Inventor: JOHNSON LIANN M
IPC: A61F2/90
Filed: 1993-03-10
Granted: 1997-03-25
Abstract: A radially self-expanding stent (90) particularly suited for treating esophageal strictures, includes a medial region (92) and proximal and distal cuffs (94, 96) having diameters greater than the medial region (92) diameter when the stent (90) is in the re-laxed state.  A silicone coating circumscribes the medial region (92), but the cuffs (94, 96) are not coated and retain their open weave construction.  As a result, the cuffs (94, 96) remain particularly well suited to immediately contact esophageal wall tissue and resist stent migration, while the silicone coated medial region (92) provides a barrier to tumor ingrowth, and has an enhanced radial restoring force to maintain an open passageway in the esophagus.  A deployment device (16) for the stent (90) includes an interior catheter (26) surrounded by the stent (90) and having an esophageal dilation feature (28), along with an exterior catheter (18) that radially compresses the stent (90).  A low durometer sleeve (54), fixed to the interior tube (26) and in surface engagement with the compressed stent (90), tends to fix the axial position of the stent (90) relative to the interior catheter (26) whenever the exterior catheter (18) is moved axially relative to the inner catheter (26).  Consequently, precision in stent placement and the abili-ty to recapture a partially deployed stent are enhanced.
