Abstract: A shoe constructed to provide exercise to a wearer while walking or jogging is provided. The shoe provides two bladders partially filled with liquid in the shoe's insole. The bladders are positioned rearward and forward and are interconnected by means of a hollow, flow resisting conduit. Heat venting is provided through fabric panels in the shoe upper, perforations in the shoe insole, metallic fibers in the shoe outsole, and vent tubes in the shoe inner sole.

Abstract: An exceptionally dense information encoding system, with 4-10 times the density of CD ROM diskettes, employs colored areas in the form of bars or checkerboard matrices of colored dot regions to encode information including alphanumerics, with each colored region being variable as to both color and intensity. In one embodiment, so-called super pixel dots have differently colored sub-regions within them, arranged with side-by-side colors or with colored regions stacked one on top of the other, such that information from one dot has as many color variables as there are stacked layers or mixed colors. In one embodiment the super pixel dot is 5 microns in diameter with 2 micron spacing between adjacent dots. For each color in one embodiment there are as many as 64 intensities yielding a coding system of high information density.

Abstract: A method is disclosed for both making microlabels and for using these labels to provide a unique system for identifying an integrated circuit (IC) die on a wafer, in one embodiment, by applying a color bar encoded microlabel, small enough to be placed on the surface of the die, with the microlabel being on the order of 2 mm.times.2 mm in overall size. In one embodiment, the label consists of a number of colored lines or bars similar to a black/white bar code, with each bar having a distinct color or hue, the width of the bars being in the 5-120 micron range in terms of width, the bars being either contiguous or separated by a thin bar of distinct color. The microlabels, whether color bar or black/white coded, are applied preferably at the wafer probing stage of manufacture, wherein each die is labelled with the bar code best expressing the parameters the manufacturer is desirous of using for further processing and/or ultimate sales and/or use.
