Abstract: Pixel information representing an image for display is coded using data compression. The data compression consists in obtaining the pixel information as a first matrix of high resolution pixel values, subtracting from this first matrix a second matrix composed of lower resolution pixel values, produced by low pass filtering the first matrix, to produce a third matrix of difference values, sub-sampling the second matrix to produce a fourth matrix of less density lower resolution pixel values and coding the third and fourth matrices. Complementary decoding consists in restituting the second matrix by interpolation filtering the decoded fourth matrix, and combining the restituted second matrix with the decoded third matrix. Loss of accuracy in the decoding method is reduced by coding and then decoding the fourth matrix during the coding method before it is interpolated to full pixel density to form the restituted second matrix which is subtracted from the first matrix to produce the third matrix of difference values. In this way, any sub-sampling and interpolation errors in the restituted fourth matrix occur in both the coding method and the decoding method and therefore cancel out. Figure 3 illustrates the coding method including these coding and decoding steps.

Abstract: Liquid crystal material is operable to alter the reflection characteristics of a mirror, for example to provide day/night rearview mirror functions. In one embodiment the liquid crystal material (12) may be selectively energized or deenergized to provide two different levels of reflection,  i . e ., substantially full or reduced levels of reflection of incident light. In another embodiment analog adjustment of the level of reflection is possible preferably together with selectivity of full or reduced level reflection. Briefly, the mirror includes a mirror support (22), a reflector (10, 11) to reflect light incident thereon, and liquid crystal material (12) for determining the amount of light reflected by the reflector (10, 11). The mirror may include plural reflectors (10, 11) with liquid crystal material (12) between the reflectors and selectively operable primarily to transmit or primarily to scatter light to determine from which of the reflectors incident light primarily is reflected. Alternatively, the reflector may be a single reflector (10ʹ) and the liquid crystal material (12ʹ) then would include volumes of liquid crystal with pleochroic dye in a containment medium, all mounted with respect to the support (22) for selectively attenuating light.

Abstract: Fibers and filaments of an ultrahigh molecular weight polyolefin that have a void volume greater than about 20% and are wettable. Wettability is imparted to the fibers and filaments by incorporat­ing a filler into the composition that is hygroscopic, has a particle size less than about 10 microns in diameter and a surface area greater than about 30 square meters per gram. The preferred fillers are those that contain surface silanol groups. The fibers and filaments are formed by the process of forming a mixture of the ultrahigh molecular weight polyolefin, filler and plasticizer, metering the mixture to an extruder, heating and kneading the blend in the extruder, conveying the extrudate to a spinneret-type die, expressing the extrudate through the die openings to form fibers or filaments, and extracting at least a portion of the extractable plasticizer to provide the desired porosity. The fibers and filaments may be formed into woven and nonwoven webs by airlaying and wetlaying techniques. Such webs are particularly useful as a battery separator.
