    摘要： A framework for in-memory space management for content management database systems is provided. A per-instance in-memory dispenser is partitioned. An incoming transaction takes a latch on a partition and obtains sufficient block usage to perform and complete the transaction. Generating redo information is decoupled from transaction level processing and, instead, is performed when block requests are loaded into the in-memory dispenser or synced therefrom to a per-instance on-disk structure.

    摘要： A method and apparatus for proactively allocating space to a logical layer of a database is provided. Allocation of space to a logical layer of a database is an expensive operation that should be minimized. The allocation of space includes discovering free space in all the higher layers in the logical storage hierarchy. It also includes cross-domain system calls and cleansing disk-write operations. In prior approaches, the allocation processes were triggered on-demand, only a certain logical layer was discovered to be at full capacity when an insert-row operation was attempted. In one embodiment of the invention, space needs are statistically predicted based on prior rates of space consumption. The database server pre-allocates space as needed, based on the statistical predictions. Rates of consumption are examined periodically. Space is pre-allocated before any logical layer reaches full capacity by a combination of proactive background processes; foreground-triggered, background processes; and classic foreground allocation.

    摘要： Methods and apparatus for expanding a rod from a collapsed position to a formed position are disclosed. One such apparatus includes a plurality of segments for forming the body of the collapsible rod including with each segment coupled to each immediately adjacent segment of the plurality of segments. The apparatus may include a coupler for coupling each segment of the plurality of segments to each immediately adjacent segment of the plurality of segments. The coupler may stretch from a base segment to the tip of the apparatus and may be biased to apply a force to hold the plurality of segments in a formed position and to urge the plurality of segments into a formed position from a collapsed position. In the formed position, the plurality of segments may be aligned end-to-end to form a rod and in the collapsed position, the plurality of segments may be folded against each other such that cylindrical walls of each of the plurality of segments are positioned adjacent each other.

    摘要： A convertible bullet-proof backpack and vest includes a body section divided into a front portion, a middle portion, and back portion. The middle portion has a head slot opening, and the front and back portions have respective sections of bullet-proof fabric integrated therein. A zipper runs around an outer perimeter of the front and back portions. In a backpack configuration, the front portion and the back portion fold toward each other and the zipper secures the outer perimeters of the front portion and the back portion together thereby forming a hollow backpack interior between them. In a bullet-proof vest configuration, the zipper is unzipped thereby allowing a user to insert their head through the head slot opening such that the front portion hangs in front of a torso of the user and the back portion hangs behind the torso of the user.

    摘要： The present invention strategically utilizes the sturdiness of thin wires enwrapped inside a thick layer of soft material such as silicone rubber which is smoother and softer than human tissue. Therefore, the device doesn't cause any damage or side effect and feels comfortable to user. The exposure of skin is 90% or higher, therefore solves the lack of sensation issue faced by prior art devices. The device is hard and yet flexible, the side walls or double bars are positioned toward ventral side of the device so that it is pleasing to the eye during use in addition to feeling good by the user.
