Patent CA-2078990-C (CA)
Title: Phospholipid-coated microcrystals: injectable formulations of water-insoluble drugs
Inventor: HAYNES DUNCAN H
IPC: A61K39/39
Filed: 1991-04-23
Granted: 2002-06-04
Abstract: Water-insoluble drugs are rendered injectable by formulation as aqueous suspensions of phospholipid-coated microcrys-tals. The crystalline drug is reduced to 50 nm to 10 um dimensions by sonication or other processes inducing high shear in the presence of membrane-forming amphipathic lipids. The membrane-forming lipid stabilizes the microcrystal by both hydrophobic and hydrophilic interactions, coating and enveloping it and thus protecting it from coalescence, and rendering the drug in solid form less irritating to tissue. Additional protection against coalescence is obtained by a secondary coating by additional mem-brane-forming lipid in vesicular form associated with and surrounding but not enveloping the lipid-encapsulated drug particles. Tissue-compatible formulations containing drug in concentrations up to 40 %  (w/v) are described.

Title: Adaptive block size image compression method and system
Inventor: LEE CHONG U
IPC: G06T9/40
Filed: 1992-06-03
Granted: 2002-05-28
Abstract: An adaptive block size image compression method and system for compressing image data, a respective method and sys-tem for further compressing the image data for transmission. Each block and corresponding sub-blocks of pixel data is subjected to a discrete cosine transform (DCT) operation (10a-10d). Varying levels of sub-blocks of resulting corresponding transform coef ficients (12a-12d) are selected for construction into a composite transform coefficient block (QC) corresponding to each input block of pixel data. The selection of transform coefficient block size for the composite block is determined by a comparison pro-cess (20, 26, 32) between transform block and sub-block coding efficiency. The composite block is variable length coded to further reduce bit count in the compressed data. A discrete quadtree transform (DQT) operation is in supplement of the adaptive block size block selection with coefficient replacement to optimize image data compression.
