Abstract: A method is disclosed herein for compressing spectral data corresponding to an image comprising a plurality of pixels. The method includes the step of creating a set of potential endmembers. A first plurality of the potential endmembers are identified as a first set of endmembers based upon their respective correlations with a first spectral signature of a first of the plurality of pixels. The first pixel is then represented as a combination of the first set of endmembers. Processing of the image preferably continues by identifying a second plurality of the potential endmembers as a second set of endmembers based upon their respective correlations with a second spectral signature of a second of the plurality of pixels. The second pixel is then represented as a combination of the second set of endmembers.

Abstract: The invention relates to a fabric cleaning article highly suited for household, commercial or industrial cleaning of fabrics which have become soiled or stained. The fabric cleaning article may desirably be used to remove spots or stains from such fabrics as clothing, upholstery and carpeting, etc., and provides for mess-free and convenient all-in-one cleaning. The fabric cleaning article includes a reservoir containing a cleaning composition for removing spots or stains, and at least a first absorbent layer secured or attached to a liquid barrier layer which keeps a user's hands and/or shoes isolated from liquids involved in the spill and from the cleaning composition.

Abstract: A lubricant is provided which has a hardness in the range 0.1-10 N/mm at all temperatures in the range 15-40° C. The lubricant consists of at least one full ester of a glycol with a fatty acid, e.g. ethylene glycol dilaurate, optionally mixed with a minor amount of a fatty acid such as stearic acid, and/or a minor amount of a partial ester of a glycol with a fatty acid. The lubricant is useful in the production of press-formed components, and particularly in techniques for converting aluminium sheet to adhesively bonded aluminium structures.
