Abstract: A heap management system for a database uses “sets” of pages to store database information. As memory for each successive set of pages is allocated, more memory is allocated for storing rows in each page of the set. Similarly, the maximum number of rows of information storable in each page of each set is greater for each successive set of pages. The number of computer instructions needed to resolve (or calculate) the memory address for a particular row is fixed. Given a target row number, (and the number of rows in the first page, and the width of the column or column group), only a fixed number of computer instructions need to be executed to resolve the starting memory address for the target row. In addition, information of the same type (i.e., one or more columns of a table) may be stored in different pages, and these pages may be located in discontiguous memory segments. This allows space for new rows to be allocated, without requiring all pre-existing rows to be moved to a different memory segment.

Abstract: A support for a gas prop (hydraulic strut) for a vehicle access door includes an elongate sleeve that is positionable around the cylinder and rod of the gas prop. The support secures a weak or otherwise defective gas prop in its position in which the vehicle access door is held open. The elongate sleeve includes a first and second end. The first end of the elongate sleeve is adapted to be selectively positioned between: (1) abutting the distal end of the cylinder, and (2) coaxially receiving at least a portion of the length of the cylinder. One or more slots are defined at the second end of the elongate sleeve. Each of the slots is selectively engageable with the shaft or post of an attachment bracket for coupling the rod end to the vehicle. Additionally, each one of the slots is a different length, thereby accommodating various lengths of gas props.

Abstract: A refreshment bar includes one embodiment of a cooling or heating apparatus for food and/or beverage containers. The apparatus maintains a food or beverage container placed on one of the plates at a desired cold or hot temperature relative to the bar surface temperature and ambient temperature. The apparatus includes thermally conductive plates, for example stainless steel disks, positioned in recesses such that the upper surfaces of the plates are coplanar with the top surface of the bar, thereby providing a level surface. A thermal exchanger system is used to cool or heat the plates. The system includes a reservoir containing a thermal element and a thermal transfer fluid. The reservoir is located adjacent the lower surface of the bar top. The plates are thermally coupled to the thermal transfer fluid and thermal element, thereby cooling or heating the plates.

Abstract: A hoop-rolling device is used by children and adults for fitness and recreation. An illustrative embodiment includes a hoop and a shaft, with a generally square-shaped ring retaining the hoop, which is used to propel and control the hoop. The ring defines a small aperture permitting selective insertion and removal of the hoop. The shaft also includes a curved handle. The device is constructed of rigid materials to allow for extended play on a variety of solid surfaces.

Abstract: A system and method for increasing hydrocarbon production from a subsurface reservoir by utilizing an intersection of two well bores and a flexible linear cutting device, such as a segmented diamond wire saw, to form a fissure beginning at the intersection of the well bores and extending along a specified the length of the well bores. The ends of the cutting device can be actuated above ground. The shape of the fissure can be a substantially ruled surface defined between the two bores between which the fissure is formed. Configurations for the well bores include both bores extending from the surface and, alternatively, a first bore extending from the surface and a second bore extending from a whipstock in the first bore. The fissure may be located and oriented to maximize the extent of the fissure formed within the hydrocarbon bearing horizon and to intersect with a maximum number of natural and/or previously formed fractures.
