  • Publication number: 20230267650
    Abstract: The present concepts relate to lossless data compression techniques for reducing the size of a data structure. Certain data in the data structure that can be either recovered from another source or rebuilt from other available information may be removed from the data structure. To further reduce data size, the retained data in the data structure may be packed into a smaller-bit encoding data type. Additionally, to reduce the data size even more, the packed data may be zipped using a lossless data compression algorithm. To regain the original data structure, the process may be reversed. The zipped data may be unzipped using a lossless data decompression algorithm. The packed data may be unpacked into the original bit-sized data encoding. The removed data may be restored by either recovering it from another source or rebuilding it from other available information.

  • Patent number: 7721352
    Abstract: An inflatable wader garment assembly includes a lower body covering with a pair of leg coverings and a lower torso covering. The lower body covering has an upper edge including a front edge and a back edge. A bladder has a top wall, a bottom wall and a perimeter wall extending between the top and bottom walls. The bladder is U-shaped and has a central portion and a pair of legs. Each of the legs has a distal end with respect to the central portion. A tube is fluidly coupled to the bladder. Air may be blown through the tube to inflate the bladder. Front straps are coupled to the distal ends and to the front edge. At least one rear strap is attached to the central portion and is attached to the back edge.

  • Publication number: 20060124221
    Abstract: An improved dual tire assembly method for free rolling applications. Each tire is constructed having the tire carcass slightly angled away from the conventional ninety degree configuration to minimize torque windup caused by interaction between the individual tires in the dual assembly. Such a deviation from ninety degrees is made relatively small enough to avoid experiencing a significant rolling resistance penalty in each tire yet large enough so that the torque windup effect of one tire on the other tire is minimized. A method of reducing torque windup in a dual tire assembly is achieved comprising the steps: configuring both tires in a dual assembly to provide a carcass angled slightly from 80 to 100 degrees; mounting such tires in proximal relationship in a dual tire assembly on a common axle; operating both tires in a free rolling mode of operation; and using the angled carcass of each tire to minimize the effect of torque windup imposed by the opposite tire.

  • Publication number: 20060048770
    Abstract: An apparatus and a method is disclosed for storage of solar energy in a subsurface geologic reservoir. The method includes transferring concentrated solar thermal energy to a fluid, thereby generating a supercritical fluid. The supercritical fluid is then injected into the subsurface geologic reservoir through at least one injection well. The subsurface geologic reservoir may be a highly permeable and porous sedimentary strata, a depleted hydrocarbon field, a depleting hydrocarbon field, a depleted oil field, a depleting oil field, a depleted gas field, or a depleting gas field. Once charged with the supercritical fluid, the subsurface geologic formation forms a synthetic geothermal reservoir.

  • Patent number: 5323824
    Abstract: An improved tire/vehicle system for an automotive vehicle has two pneumatic front tires and two pneumatic rear tires. The rear tire treads and the front tire treads and are each divided circumferentially into first, second, and third zones. The edge between the second and third zone in each front tire is in the center of an aquachannel. The edge between each of the three zones in the rear tires are in the center of an aquachannel. Both the front and rear tires have a tread groove pattern that is asymmetric in character.
