An engine structure and mechanism that operates on various combustion processes in a two-stroke-cycle without supplemental cooling or lubrication comprises an axial assembly of cylindrical modules and twin, double-harmonic cams that operate with opposed pistons in each cylinder through fully captured rolling contact bearings. The opposed pistons are double-acting, performing a two-stroke engine power cycle on facing ends and induction and scavenge air compression on their outside ends, all within the same cylinder bore. The engine includes a novel compressor arrangement having an intake valve comprising a V-shaped double reed valve with an apex pointing toward the intake port and an exhaust valve having a V-shaped double reed valve with an apex pointing away from the exhaust port. The compressor arrangement may further include rectangular intake and exhaust ports, a rectangular piston rod and rectangular crosshead bearings.

A digital data processing system with improved network access to files in a storage system has a plurality of digital data processing nodes and a storage device. First or “client” nodes locally cache meta data such as maps to file data stored on the storage device and directly mount the file system using their cached data. A second “server” or MDC node connects to the storage device and mediates access to files, issuing file change notifications over the network for changed files or meta data. The second node preferably implements a SAN shared access storage system, and initially provides the maps for requested files, from which each of the first nodes builds their own cache in a natural way. In further embodiments, the client nodes may register for access to particular file areas or sub-directories, and may then receive change notifications only for their registered access-areas or portions of the data tree; alternatively, the second node may determine scope of necessary notifications from the set of previously-accessed files. A file application on the client inspects change lists to determine whether to directly access (or use previously accessed file data) using the cached information, or whether a desired file must be accessed by requesting new maps from the second node through a network file sharing protocol. The system operates on the premise that large parts of the file system remain unchanged for a substantial time. Thus, rather than arbitrating each request for file access, the file notification system publishes and updates one or more lists of file changes. These may identify portions of the file directory cached at a client node that are either off-limits, or require specific determinations as to their continued usability. The local file application implements a two-stage access protocol that allows direct mounting of the file system by all or a subset of client nodes for both files and meta data, and extends the time during which file accesses by cached data may be effected. The notification system may run on a server node configured to implement shared storage by interfacing with and coordinating file access, write and block re-allocation operations of a native file management system to maintain file integrity, coherence or security, and may apply the change list to prevent local file applications from accessing restricted data as well as preventing client node use of changed file data or outdated data maps.

A multimedia business communications platform enables conference casting over a network. End users or so-called “audience members” participate in conference casts from anywhere on the Internet or behind an enterprise firewall using a standard Web browser running a streaming media player. The conference platform typically includes a number of subsystems: a Web reservation subsystem, a voice server subsystem, a content storage subsystem, a monitoring data subsystem, an attendee access subsystem, and an archive subsystem. Web reservation subsystem provides a mechanism that enables an entity to make an event reservation. Web reservation subsystem typically includes a database and an associated database management system. Voice server subsystem validates a user and converts an incoming telephone signal (i.e., the conference call) to an output data stream. Attendee access subsystem responds to attendee requests and returns information (e.g., a data structure such as a stream metafile) that directs an attendee's streaming media player on how to join the conference cast. Content storage subsystem is used to manage event information and, under the control of the archive subsystem, to archive the event files. The monitoring data subsystem comprises a set of monitoring agents distributed throughout the network. Using these components, the system implements just-in-time resource provisioning, automated signal acquisition and streaming, and automated archiving upon event completion.

Computer-supported prognosis of the reliability of a technical system, which comprises a processor on which programs are run determines an analysis and/or projection prognosis figure, which gives the expected complexity for generation of the programs in a metric for the analysis and/or the projection. An implementation figure is determined from the analysis and/or projection prognosis figure which gives the expected complexity for production of the programs in a metric for the implementation. Finally a reliability prognosis figure is determined from the implementation prognosis figure which gives the expected reliability of the programs.

The metering pump is preferably a valveless rotary piston pump, and for the color changer a suitably miniaturized arrangement and construction for the valve assemblies is preferred.

Fluid-dynamic-pressure bearing manufacturing method for more efficient and fail-safe degassing of bearing oil. Method makes it possible to prevent the generation of air bubbles in the course of an oil-charging operation that amounts to a step following degassing, and to single out the causative source of air bubbles when their generation has been detected. At the same time oil that is under a reduced-pressure environment within an oil-storing vacuum chamber is vacuum-degassed, immersed within the oil a stirrer for agitating and degassing the oil is rotated by indirect drive means, and the oil after having been degassed is supplied to a vacuum chamber where a fluid-dynamic-pressure bearing unit is retained—which has been pumped down to a pressure below the pressure within the oil-storing vacuum chamber—and is charged into the bearing clearances by raising the internal pressure of the bearing-retaining vacuum chamber.

This device will allow individuals to pass through explosive detection portals efficiently without undue delay. The airflow from a series of jets will dislodge embedded molecules and direct them to a sensor that will detect the presence of commonly found explosive materials. The molecules that are dislodged will be accomplished by air flow through an air tunnel or portal structure that is not invasive to the person yet allows real time detection of explosive material while not infringing on the privacy of the individual.
