20080196699 | Gravity-controlled constant-pressure and pressure-regulation device - A gravity-controlled constant-pressure and pressure-regulation device includes a canister, a weight block, and a seal head. The canister includes a metal layer, an epoxy resin layer, and a plastic sheet layer. The metal layer serves as an inner lining. The epoxy resin layer surrounds an outer circumference of the metal layer. The plastic sheet layer surrounds an outer circumference of the epoxy resin layer. The weight block is movably received in the canister. The metal layer has an inner surface movably and receivingly engages the seal head. The weight block is mounted to the seal head. The weight block is movable upward and downward inside the canister by being acted upon by a gravity force of weight thereof and a lifting force induced by an internal pressure inside the canister to effect mass storage of air inside the canister and stable supply air at constant pressure. | 08-21-2008 |
20080197632 | Air-blower tidal power generation device - An air-blower tidal power generation device includes a rack, an air-blower mechanism, and a power generation mechanism. The air-blower mechanism includes a pumping device, a buoy, and an air conduit. The pumping device includes a cylinder and a stationary barrel movably coupled together. The power generation mechanism includes a constant-pressure and pressure-regulation device and a power generator having an air-driven turbine. Thus, tides move the buoy up and down to drive the pumping device for cyclically drawing and pumping air, and the air is preserved in the constant-pressure and pressure-regulation device to provide a constant pressure for subsequent and stable supply of airflow to the turbine for driving the power generator to generate power. | 08-21-2008 |
20090169121 | STATIC IMAGE COMPRESSION METHOD AND COMPUTER READABLE DATA STRUCTURE AND COMPUTER READABLE STORAGE MEDIUM - A static image compression method, a computer readable data structure, and a computer readable storage medium are described. Firstly, an image is segmented into a plurality of sub-images. Then, each sub-image is sequentially compressed into a sub-data frame having a start character, so as to generate a compressed data with the sub-data frames interconnected according to a sequence of the sub-images. Finally, the addresses of the start characters are recorded to generate an index data. Thereby, the start character of a particular block can be obtained from the index data, and the sub-image of the particular block is preferentially decoded and displayed. | 07-02-2009 |
