Abstract:
A method of affecting soot particulate size in an internal combustion engine exhaust by selectively providing a phosphorous based additive to the engine during combustion. Soot particulate size can be increased or decreased depending on the particular additive provided. Also disclosed in a conditioning effect experienced by using a phosphorous based additive for a period of time. A conditioned engine can also have its exhaust properties affected during the life of its conditioned state. Manipulating particle size during engine operation can employ an oligomeric phosphorous compound. Engine conditioning can employ a monomeric phosphorous containing compound, an oligomeric phosphorous containing compound, a polymeric phosphorous containing compound, or combinations thereof.
Abstract:
A unit of data is read from memory of a replicated cache. The replicated cache comprises a plurality of independent computing devices. Each independent computing device comprises a processor and a portion of the memory. Confirmations are received from at least a majority of the independent computing devices that a flush operation for the unit of data was initiated no later than a time indicated by the timestamp and that a more recent version of the unit of data has not been flushed. The unit of data is provided to storage.
Abstract:
The invention provides a method of bonding a sensor to a surface comprising the steps of applying a thermoplastic film to a first surface of the sensor. The first surface of the sensor is contacted with a surface of an object to be monitored, wherein the composition effectively bonds the sensor to the object surface at a temperature up to approximately 250° C. The invention also provides a method of bonding a sensor to a surface comprising the steps of applying a thermoplastic film to a surface area of an object to be monitored. The first surface of a sensor is contacted with the object surface area, wherein the film effectively bonds the sensor to the object surface at a temperature up to approximately 250° C.
Abstract:
An apparatus for use with a router that is adapted to secure a guide bushing to a base of the router includes a modified retaining nut that includes a plurality of extensions that extend radially away from the nut. Each extension includes a threaded hole that is adapted to receive a set screw. The retaining nut includes interior screw threads that cooperate with outside screw threads of the guide bushing. The guide bushing is disposed on one side of a hole provided in the base of the router and the retaining nut is lightly tightened secure the guide bushing in a recess provided in the router base. The set screws are then tightened and bear against the router base sufficient to urge the retaining nut away from the guide bushing thereby placing the screw thread of both under tension, while simultaneously engaging with the router base sufficient to retain the retaining nut in position relative to the router base.
Abstract:
A tool holder assembly having a cutting tool, a tool holder, and a sealing portion. The sealing portion is configured to inhibit fluid leakage between the cutting tool and the tool holder.
Abstract:
Compositions for removing incidental soils from fabric articles, especially articles of clothing, linen and drapery, provide improved cleaning of incidental soils, either with or without a subsequent wash process. Methods for use of the compositions are also provided. The compositions and methods are safe for use on a wide range of fabric articles, even in the home.
Abstract:
The present invention provides a method and apparatus for granular management of network resources by accessing network device resources through associated references. In one embodiment, the references are group names, and one or more resources (i.e., a resource collection) within each network device in a telecommunications network may be linked with one or more group names. Group names (or other types of references) may then be used to limit a user's access to particular network device resources. That is, a user may only have access to those resources associated with group names to which the user has access. Over time, network device resources may be associated or disassociated with particular group names. As a result, group names provide users with dynamic access to network device resources. In one embodiment, the groups to which a user has access are defined within a user profile associated with the user. Grouping network device resources, therefore, allows for a granular view of each network device in the network by limiting a user's access to those resources corresponding to group names listed in their user profile. As one example, grouping may allow for customer network management—that is a customer's view is limited to only those network device resources for which they have subscribed.
Abstract:
A computer operable method for integrating and automating test procedures within a computer application program. Instantiated test operation objects of an object class defined by the present invention correspond to functions to be tested within the computer application program. The test operation objects are instantiated by calls to functions in a test operation runtime library (DLL). The test operation objects include interface method functions which execute the intended test operation and simulate any required data, file, or memory I/O. Other aspects of the methods of the present invention provide rules which permit decisions as to the applicability of each test operation given the state of the application program or the context of the test operation sequence. The various test operation objects are selected to perform a sequence of test steps. In one mode of operation, the methods of the present invention randomly select among all the instantiated test operation objects. In another mode of operation, the methods of the present invention “playback” a previously recorded sequence of test operation objects to permit reproduction of failures in previous test sequences. In a third mode of operation, the methods of the present invention permit a user to modify or create “playback” files to customize a test case for a particular focus.
Abstract:
Metadata described herein on a RAID array includes both device metadata and RAIDset metadata. The device metadata has a device FE bit on each storage device corresponding to each RAID protected block on the storage device. The device FE bit indicates if a corresponding RAID protected block is consistent and thereby useable to regenerate data in another RAID protected block in the corresponding RAID protected block's sliver. The user data also has a forced error bit to indicate if a physical block in the user block has inconsistent data, the RAIDset FE bit. The RAID array of storage devices has user data blocks on each storage device RAID protected by being distributed as slivers of blocks across the RAID array of storage devices. Each sliver has a plurality of user data blocks and one parity block. The RAIDset metadata has the RAIDset FE bit corresponding to each RAID protected user data block in the RAID array. The RAIDset FE bit indicates whether or not a corresponding RAID protected user data block contains true data. In addition, FE Dir bits corresponding to each block of FE bits for the device or the RAlDset are added to the metadata. Further the device FE bits, the RAIDset FE bits, the device FE Dir bits and the RAIDset FE Dir bits are in RAID protected blocks in a RAIDset sliver having RAIDset FE bit blocks. RAIDset FE Dir blocks, and a parity block.
