Abstract: A video compression method may include providing and transmitting encoder commands for sequences of one or more pixels in a video frame in a YCbCr color space from a set of hierarchal encoder commands. A particular encoder command for a particular sequence may include on of a copy command, a delta command, or a make pixel command. A copy command may indicate that the particular sequence is identical to one of a previous pixel in the video frame, a pixel located above a first pixel of the particular sequence in the video frame, or a pixel in a previous video frame at a location of the first pixel. A delta command may indicate that the particular sequence includes a single pixel with color values equal to the previous pixel in the video frame combined with a signed color delta. A make pixel command may provide color values of particular sequence.

Abstract: A combination name badge and compass includes a substantially planar substrate having a front surface that has name indicia thereon, and a rear surface and a clutch bar that includes spaced pins. The clutch bar is secured to the rear surface of the planar substrate with the pins extending away from the planar substrate. A magnetic circuit includes a pair of opposite polarity magnets mounted at the substrate. The magnetic circuit further includes a metal arrow that is coupled with the opposite polarity magnets to form the magnetic circuit. When the name badge is floated on a liquid surface the metal indicator points to magnetic north.

Abstract: In one embodiment, a nonwoven filtration medium is provided comprising substantially continuous sheath/core bicomponent filaments arranged to form an open, porous, fluid permeable spunbond nonwoven fabric. The core component of the filaments comprises polyester or polypropylene and the sheath component comprises polyethylene having a melting temperature less than the melting temperature of the core component and including an organic antimicrobial agent incorporated therein. A multiplicity of bond sites are distributed uniformly throughout the fabric and defined by regions where the lower-melting sheath component has softened and flowed together at filament cross-over locations, with the individual being filaments spaced apart from one another except at the filament cross-over locations. The spunbond nonwoven fabric preferably has a thickness of about 10 to 40 mils and an air permeability from 150 to 270 cfm/ft2/min.
