Abstract:

The present invention is directed to a multimedia data storage system for storing multimedia data including a media server which stores media data on a short-term basis, and a media archive which stores media data on a long-term basis relative to the media server. The media archive is connected to the media server, which operates as a cache device for the media archive, for transmission of media data between the media archive and the media server. According to the present invention, a volume of the media data stored in the media server is controlled based on user-defined parameters. The present invention is also directed to a method of managing a media server as a cache device for a media archive within a multimedia data storage system. The media server stores media data on a short-term basis, whereas the media archive stores media data on a long-term basis relative to the media server. The media archive is connected to the media server for transmission of media data therebetween. According to the present invention, the method of managing includes determining a volume of the media data stored in the media server and controlling the volume of the media data stored in the media server based on user-defined parameters. The present invention is also directed to a computer-readable medium of instructions to be implemented in a multimedia data storage system including a media server and a media archive. The media server stores media data on a short-term basis and the media archive stores media data on a long-term basis relative to the media server.

Abstract:

According to the present invention, a media manager is provided which incorporates an application program interface (API) for converting high-level generic commands into device-level commands for output to a media device. The inventive media manager includes a high-level command processor which decodes the high-level generic commands and device-specific code mapping modules which convert the high-level generic commands decoded by the high-level command processor into device-level commands. Each of the device-level commands is output from one of the device-specific code-mapping modules to a corresponding one of the media devices. The present invention also encompasses a method of implementing an application program interface (API) for media devices. The method includes receiving high-level generic commands from a computer application, converting the high-level generic commands into device-level commands, and outputting each of the device-level commands to one of the media devices. The present invention also encompasses a computer program product including a computer-readable medium. The computer program product includes means for decoding high-level generic commands, means for converting the high-level generic commands into device-level commands, and means for outputting each of the device-level commands to a corresponding one of the media devices. The present invention further encompasses a common application program interface (API) which converts high-level generic commands received from a computer application into device-level commands which are output to a plurality of media devices including media servers which stores media objects. The common API includes a plurality of individual APIs which each perform a specific function.

Abstract:

Setting parameter values are migrated through a new software upgrade. Each software version includes a version number. The version number of the new software is compared to a version number of the current software. The version number of the current software is determined by reading a version number parameter value stored in a non-volatile random access memory (NVRAM). If the version number of the new software is higher than the version number of the current software, for each setting parameter value within a new map file, either a current setting parameter value stored in the NVRAM or a default value from the map file, is loaded into a temporary memory. The map file, corresponding to the current version number parameter value stored in the NVRAM, is used to associate th

Abstract:

The present invention provides a method and system of assigning a publication date for at least one electronic document, where the publication date includes the year that the document was published, the month that the document was published, and the day that the document was published. In an exemplary embodiment, the method and system include (1) recognizing the publication date in the document by regular expression pattern matching, (2) if the publication date is ambiguous, resolving the ambiguous publication date, and (3) validating the publication date. In an exemplary embodiment, the recognizing includes determining at least one candidate publication date from the document identifier of the document. In an exemplary embodiment, the recognizing includes determining the publication date from the textual content of the document. In an exemplary embodiment, the recognizing includes determining the publication date from the metadata of the document.

Abstract:

Setting parameter values are migrated through a new software upgrade. Each software version includes a version number. The version number of the new software is compared to a version number of the current software. The version number of the current software is determined by reading a version number parameter value-stored in a non-volatile random access memory (NVRAM). If the version number of the new software is higher than the version number of the current software, for each setting parameter value within a new map file, either a current setting parameter value stored in the NVRAM or a default value from the map file, is loaded into a temporary memory. The map file, corresponding to the current version number parameter value stored in the NVRAM, is used to associate the values in the NVRAM to their corresponding setting parameters. Once a value for each setting parameter is loaded into the temporary memory, the values from the temporary memory are then loaded into the NVRAM.

Abstract:

A process, composition and apparatus for the removal of impurities from corrosive gases, particularly halogen-containing gases, down to about 100 ppb concentration are described. The critical component is zirconia (ZrO), which in a variety of physical forms is capable of dehydrating such gases. The zirconia can be in the form of a coating on a substrate, as a granular bulk material, or deposited within the pores of a porous body. The zirconia is retained in a simple container which is easily installed in a gas supply line, such as to a gas- or vapor-deposition manufacturing unit. The purification process can be operated for long periods of time in the presence of these gases. The invention provides final purification to gas streams intended for gas- or vapor-deposition formation of high purity electronic, prosthetic or similar products, and can be used in combination with a preliminary dehydration process or a solid particulate removal unit upstream.
