Inventor: KNARVIK JONAS MIN
IPC: B62B15/00
Filed: 2004-11-12
Granted: 2012-04-17
Abstract: A device for use in activity on snow-covered surfaces, water or also on another surface, comprises a bottom board (1) for contact with the surface, equipped with longitudinal steering ribs on the underside and with upwardly curved faces at the front edge and preferably also at the rear edge, and a top board (2) that is adapted to the user and his position of use by the formation of well-like depressions along the side areas for the user's legs and having an air bag (3) for support of the user. The bottom board (1) and the top board (2) are joined together along their edges and define a hollow space between them. An airtight bag (3) that projects above the top board (2) is located in the central area of the device. The bottom board (1) has a longitudinally flat or slightly concavely curved central portion (10) which extends from the curved front portion to the rear portion of the board, and with side faces (11) on each side that are higher than the central portion and the surface for the board. The central portion has at least one, preferably two, central steering grooves (12) that extend along the whole length of the central portion, preferably with steering ribs (13A) at the edge area on each side, which are shorter than the groove (the grooves) in the central area and are flattened towards the forward and rear end areas of the central portion. The side faces are flat, but inclined slightly upwards towards a substantially curved face part which forms the transition to the top board. The side faces on each side in the area of the substantially curved face part are equipped with a steering runner (14) projecting at an angle from the side face. The front of the device is equipped with fastening means for a towing line.

Abstract: A method of operating a multi-processor video encoder (Fig. 2) by determining a target size corresponding to a preferred number of bits to be used when creating an encoded version of a picture in a group of sequential pictures making up a video sequence (See Fig. 2, item 16). The method includes the steps of calculating a first degree of fullness of a coded picture buffer at a first time (See Fig. 2, item 8), operating on the first degree of fullness to return an estimated second degree of fullness of the coded picture buffer at a second time (See Fig. 2, item 12), and operating on the second degree of fullness to return an initial target sized for the picture (See Fig. 2, item 28). The first time corresponding to the most recent time an accurate degree of fullness of the coded picture buffer can be calculated and the second time occurs after the first time (Fig. 2, items 20 and 28).

Title: Water sanitization system having safety features and removable filter
Inventor: HENGSPERGER STEVE L
IPC: C02F1/78
Filed: 2006-03-17
Granted: 2010-11-30
Abstract: A removable disposable air dryer cartridge is provided for a small enterprise water ozonation system. The cartridge includes an air inlet to receive atmospheric air, a desiccant material to remove moisture, and a dry air outlet for interfacing with the ozonation system to provide dry air to an ozone generator. This facilitates better ozonation of water in the system, since dry air reacts better in an ozone generator, achieving higher concentrations of ozone gas, thus resulting in a better "kill rate" when ozonated water is applied to bacteria. The air dryer can be provided as a chamber of a combined air dryer and water filter cartridge, the other chamber being a water filter chamber having a water filter for extracting large particles of material from the water stream in order to prevent damage to the system.
