Abstract: A system and method employing a virtual restore disk, such as a vendor supplied CD-ROM, allows software restoration from the vendor's software library. The customer's original software configuration is archived and the customer may use the virtual restore disk for restore purposes as necessary, e.g., to restore a deleted file, replace a suspected corrupted file, etc. The vendor maintains updated versions of the software so that unlike a static restore disk, the customer is not limited to the releases available at the time of system purchase. The virtual restore disk can also be used to update a user's system, even in the absence of system malfunction.

Abstract: A method for reducing data/parity inconsistencies due to a storage controller failure in computer storage systems with dual, independent storage controllers and a number of logical volumes comprising one or more physical disk drive devices includes recognizing a failure of the storage controller; assuming access control of the volume; and thereafter, performing at least one write to the volume, wherein, for a predetermined number of writes (N) to the volume after failure of the storage controller, new parity is calculated for the write using new data and other data (Method 2). The predetermined number of writes (N) is at least equal to or greater than the queue depth of the failed storage controller (i.e., the number of I/O operations that the failed storage controller may service at a given time. The method may be implemented by each storage controller of the computer storage system.

The inner gear casing houses an arbor assembly that connects with the bit and the motor. A height adjustment assembly coupled with the offset base assembly and the inner gear casing allows a user to adjust the height of the inner gear casing relative to the base and the sub-base.

Abstract: The present invention provides improved chlortetracycline-containing animal feed compositions and processes and apparatuses for their preparation. In certain embodiments, raw fermentation broth comprising chlortetracycline is divided into two portions. The first portion is mixed with a compound that complexes chlortetracycline. The second portion is acidified and the solids are removed. The acidified liquid is treated with a complexing agent to produced a chlortetracycline complex. The first and second portions thus treated are then mixed and the mixture is passed on to a filter press or other means for separation of the solids to produce a wet cake comprising complexed chlortetracycline. In alternative embodiments, the second portion may be acidified and filtered and admixed with the first portion prior to the complexing step. The resulting mixture is passed on to a filter press or other means for separation of the solids.

Abstract: A method and apparatus for providing viewer specific program information is described. A user of an integrated personal computer and television convergence device requests specific programming information from a remote server using an electronic program guide. The remote server performs a database search based upon the requested information and caches the results of the database search in a local storage device. The database search result information is viewer specific and appended to or integrated with the requested electronic program guide. Advanced searching techniques may be utilized to manipulate and filter the searched information to maintain the viewer specific integrity thereof. The database search result information is thereby provided to the client or convergence device along with the requested programming information. The database search result information thereby supplements and augments the viewing experience of the viewer.

Abstract: A wallpaper dispensing apparatus includes a tray with a ridge projecting from the bottom and extending transversely between the side walls to divide the tray into a forward pool section and a rearward trough section. A removable cover is attached to the forward pool section and includes a pair of depressions with guide surfaces on the bottom, spaced above the bottom of the tray to form a passageway between the cover and tray bottom. The cover has a rearward portion following a portion of the ridge, and a straight rearward edge extending transversely across the tray. An opening in the cover, extending from the forward edge permits the user to draw a strip of wallpaper from a roll located in the trough, through the passageway between the cover and tray, and out the forward end of the tray. Water in the pool portion wets the wallpaper as it is drawn from the dispensing apparatus.

Abstract: A method is disclosed for enabling functions of an information handling system such as startup (i.e., boot), loading of an operating system or execution of a software application, by requiring authentication of the information handling system. A client information handling system establishes a communication link with a central system or server via a network such as a Local Area Network (LAN) or the Internet. A request for authentication is then sent to the central system by the information handling system via the communication link. The central system, upon receiving the authentication request from the information handling system, determines if the authentication request is valid, and, if valid, provides authentication of the information handling system via one or more encrypted tokens passed from the central system to the information handling system, thereby allowing the information handling system to provide or continue to provide the function, even when disconnected from the network.
