Abstract: A sprite-based coding system includes an encoder and decoder where sprite-building is automatic and segmentation of the sprite object is automatic and integrated into the sprite building as well as the coding process. The sprite object is distinguished from the rest of the video objects on basis of its motion. The sprite object moves according to the dominant component of the scene motion, which is usually due to camera motion or zoom. Hence, the sprite-based coding system utilizes dominant motion, to distinguish background images from foreground images. The sprite-based coding system is easily integrated into a video object-based coding framework such as MPEG-4, where shape and texture of individual video objects are coded separately.

Abstract: A tool holder slides over a tool protecting it from water and other rust inducing conditions. The tool holder comprises a cover having an internal cavity that holds two retainer sections of polyethylene. The retainer sections are sized to conform with the exterior profile of the tool and press firmly against opposite exterior surfaces of the tool as it is being inserted inside the tool holder. The retainer sections hold the tool snugly inside the cover cavity providing a highly effective insulation barrier. A lubricant is insertable inside the cover cavity and absorbed by the retainer sections and is automatically applied to the exterior surface of the tool as it is being inserted into the tool holder. The inside face of each retainer section have an abrasive surface that automatically scrubs the exterior surface of the tool while it is being inserted and removed from the holder.

Abstract: The invention is an interlocking lockout device for a computer system. The lockout device comprises a locking disk dimensioned similarly to a floppy disk for so that it can be inserted and locked into a disk-drive. An engagement member of the locking disk interlocks with a bezel. In a locked position, the bezel covers the disk-drive preventing the locking disk from being removed from the disk-drive and preventing foreign matter from being inserted into the computer and disk-drive. While inserted, the locking disk keeps the computer system from booting and thereby prevents unauthorized operation of the computer system. The bezel and locking disk are adaptable on any size disk-drive and can easily be installed on different systems. This provides a lockout capability for computer systems with multiple drives and variable sized disks.
