Abstract: A computer implemented method, apparatus, and computer usable program code for preserving a virtual file system. Data for a virtual file system is received. The data include file handle information, vnode information, and gnode information. The data is saved to a storage device. The saved data can be used to reconstruct the virtual file system upon changeover between a primary data processing system and a backup data processing system.

Abstract: Provided is a method for implementing a file system that includes a combination of read-only and read/write parts. A file system located on a data server maintains an original copy of a data store. An “Ephemeral” file system (EFS) is created on a client computer. The data server is contacted only once for each file accessed and the copy is in an original state each time the system is mounted. Changes made to the file system by one client are not seen by other clients. The EFS maintains the file system state in memory and uses the NFS server as a backing stored for cached file data. File data for files created on the client are backed up by the client system's swapping space.

Abstract: Systems that maintain objects created and modified within designated directories on a per-client basis in a network filesystem include a file server having a local processor, memory operably connected to the local processor, a filesystem including main directories loaded into the memory, and a list of operations loaded into the memory; at least one client operably connected to the server having a remote processor and memory operably connected to the remote processor; wherein the file server has designated at least one of the main directories as a per-client writable directory; and wherein the file server has exported the filesystem read-only to at least one client.

Abstract: A method, system, and computer-usable medium for implementing a file directory in a server. An application including a buffer for retrieving and storing at least one entry is interfaced with the file directory. Utilizing a determined average filename length, an estimate of a number of entries among the collection of entries that can be stored by the buffer is determined. In response to determining at least one attribute data field has been requested, the number of entries that can be stored by the buffer is recalculated. Recalculating the number of entries includes determining an amount of data required for storing the collection of filenames, a collection of fixed-length attribute data fields, and a collection of variable-length attribute data fields. The recalculated number of entries is then requested from the file directory, and the buffer is loaded, with the recalculated number of entries.

Abstract: A method, system and apparatus for exporting file systems without having to mount them first are provided. Most Unix-based servers usually mount some system operation critical files at startup. Thus, directories have to be mounted. One or more of these directories are usually used as mount points for mounting other file systems when needed. An extended attribute file is used to provide all information needed to export a file system. Thus, a server need not mount a file system to obtain this information. That is on startup, a server needs only refer to these extended attribute files to obtain the information needed to export the file systems.

Abstract: According to one aspect of the invention an aquatic propulsion device is provided comprising a harness to be worn on the body of a person, at least a first elongate member, and at least a first paddle. The first elongate member has first and second opposed ends and a first grip. The first end is pivotally securable to the harness. The first paddle is secured to the second end of the first elongate member. The first grip is positioned so that a person, when wearing the harness, can reach and hold onto the grip with a first hand and move the first grip so that the first elongate member and the first paddle pivot relative to the harness.

Abstract: A random access audio/video processor having multiple outputs is disclosed. The processor includes a main control unit with analog video and audio back panels, an analog input/output board, audio and video processing boards, video effects board, synchronization board, and a system board (containing the main CPU). The video processing board includes a compressor for compressing input video signals, and triple transfer buffers for intermediate storage of digital video path. The video processing board further includes decompression circuits coupled to each of two triple transfer buffers for decompressing compressed stored video, and providing the decompressed video channels to an effects board for the addition of special effects. The audio processing board contains processors for compression, decompression, and effects, as well as triple transfer buffers. The triple transfer buffers include present, past, and future buffers which jointly operate to minimize discontinuities in the output channels.

Abstract: A method for the removal and recovery of paint overspray in a water wash spray booth is disclosed. The method uses a circulating agitated dispersion of an organic solvent component in water which collects the paint overspray. The dispersion containing the overspray is permitted to phase separate into an organic phase and an aqueous phase. The organic phase is further treated such as by distillation to separate the paint solids from an organic solvent portion which contains the original organic solvent component and the organic solvents associated with the paint. The organic solvent portion can be recycled and reused in the circulating dispersion and the paint solids can be recovered for further use such as a filler for adhesives or can be disposed of.

Abstract: Method and apparatus for construction and use in real time of a sequence of pixel-to-pixel mappings that define a video image transformation of a sequence of video images in digital animation video image processing and display. A sequence of compressed mappings that approximate the required sequence of pixel-to-pixel mappings is constructred off-line, and this sequence of compressed mappings is stored for subsequent use and is designated by a selected indicium. When that sequence of pixel-to-pixel mappings is to be applied to a chosen set of video image fields, the sequence of compressed pixel mappings is called up by use of the indicium, the compressed mappings are decompressed, and the sequence of decompressed mappings is applied to the chosen set of video image fields in real time.

Abstract: A paint spray booth masking composition comprising:______________________________________ Ingredients % by weight ______________________________________ Water 30-50 Polyvinylpyrrolidone 2-30 Saccharide 16-60 Water-soluble surfactant 0.07-0.13 Preservative 0.05-0.

Abstract: First and second stop bodies are arranged to clamp around the lever of a pedal which operates an apparatus. When the stop bodies are locked in place, the pedal cannot be operated and, thus, the apparatus is restrained.

Abstract: In accordance with a preferred embodiment of this invention, a decorative and protective coating is electrodeposited on a negatively charged metallic substrate from an acidic aqueous dispersion. The dispersed particles contain a film forming addition polymer, copolymer or mixtures thereof. This addition polymerization reaction product has occasional but randomly distributed pendent aminimide and pendent hydroxyl functionalities. The hydroxyl and the aminimide functionalities are present in about equal amounts. Once deposited, the coating is cured at a temperature of about 120.degree. C. or above.
