Abstract: An orthodontic device treats malocclusions using a telescopic rod fixed to a molar on the upper arch and a molar on a lower arch. The telescopic rod lengthens and shortens during opening and closing of the jaw. The telescopic rod encourages the patient to properly position their jaw causing adaptation thereby treating the malocclusions.

Abstract: A database engine and optimizer framework support creation of a series of profiling indices over a column having character string data, such as a traditional “varchar” data type. The profiling indices result in a reduction of the number of records that are searched when searching for a sub-string match within that column. In some embodiments, the series of indices are created over a column that is typically searched using the LIKE predicate or some similar technique; these indices indicate for each record whether certain sub-strings may exist in that record's value in the column. Thus, the indices are used to find the rows that may match one or more portions of the particular term being queried or, in other words, eliminate those records that do not have at least a portion of the term to be matched. The number of records actually retrieved and searched for the query sub-string is thereby reduced.

Abstract: An apparatus and method utilize compressed cache lines that incorporate embedded prefetch history data associated with such cache lines. In particular, by compressing at least a portion of the data in a cache line, additional space may be freed up in the cache line to embed prefetch history data associated with the data in the cache line. By doing so, long-lived prefetch history data may essentially be embedded in a cache line and retrieved in association with that cache line to initiate the prefetching of additional data that is likely to be accessed based upon historical data generated for that cache line, and often with no little or no additional storage overhead.

Abstract: Redundant capacity in a memory system is utilized to facilitate active monitoring of solid state memory devices in the memory system. All or part of the data stored in an active solid state memory device, and used in an active data processing system, may be copied to at least one redundant memory device, e.g., by transitioning a memory address range that was allocated to the active memory device to the redundant memory device. By doing so, memory access requests for the memory address range, which would normally be directed to the active memory device, may instead be directed to the redundant memory device, thus enabling the active memory device to be tested (e.g., via writing and reading test data patterns to the active memory device) without interrupting system access to that memory address range.

Abstract: An apparatus and method to significantly improve performance of SQL function processing through the use of an encoded vector index (EVI). An EVI provides the data necessary to count the number of records in a database that match criteria provided by a SQL function. The resulting count can then be used to determine, from among two or more candidate approaches, an approach to use in processing an SQL function. By processing the EVI symbol table in lieu of more traditional database indexes, and/or in lieu of the database table itself, statistics for SQL functions are generated significantly faster.

Abstract: A computer system, program product and method to facilitate debugging of multi-threaded computer programs by identifying threads that interact with program elements such as instructions or variables. For instance, after program execution is halted by a break point, a user may request retrieval of an identification of all threads encountering a certain statement number. Moreover, the program element may be implemented as a thread identification control point in a manner similar to a break point, utilizing a break point table to determine whether a system exception is due to a break point or to a thread identification control point. If the latter, program execution continues after storing the thread identifier in a record for the thread identification control point in the break point table.

Abstract: A polymerizable monophosphate ester dispersant, a highly-filled nonaqueous suspension containing the polymerizable monophosphate ester dispersant, and a method for forming cured articles by copolymerization of the resin matrix and dispersant in the suspension. Inclusion of the dispersant in a suspension of resin and solid particulate material enables an increase in the solid loading, which results in reduced shrinkage, a lower coefficient of thermal expansion and generally improved physical properties in an article cured therefrom.

Abstract: A memory cache sequencer circuit manages the operation of a memory cache and cache buffer so as to efficiently forward memory contents being delivered to the memory cache via the cache buffer, to a multithreading processor awaiting return of those memory contents. The sequencer circuit predicts the location of the memory contents that the processor is awaiting, and speculatively forwards memory contents from either the cache buffer or memory cache, while simultaneously verifying that the speculatively forwarded memory contents were correctly forwarded. If the memory contents were incorrectly forwarded, the sequencer circuit issues a signal to the processor receiving the speculatively forwarded memory contents to ignore the forwarded memory contents. This speculative forwarding process may be performed, for example, when a memory access request is received from the processor, or whenever memory contents are delivered to the cache buffer after a cache miss.

Abstract: A quilting machine is provided having at least one set of single needle stitch forming elements for forming chain stitched patterns on a thick multilayered material such as a mattress cover. The machine is preferably web-fed, with a panel of the continuous web being clamped and held stationary on a frame. The stitch forming elements include a needle and a looper mounted on separate heads that are independently moveable on a bridge transversely relative to the panel, which is moveable longitudinally relative to the frame. The bridge is longitudinally moved by a servo and the heads are transversely moved on the bridge by separate servos. The stitching elements on each head are driven by separate servos. A controller drives the servos to chain stitch patterns and differentially move the heads transversely to account for transverse needle deflection. The drives of the needle and looper are phased to compensate for longitudinal needle deflection. The controller determines or predicts needle deflection.

Abstract: An asphaltic concrete or paving material includes at least 5 percent, and preferably from 5 to 20 percent, of granular recycled plastic, which supplements or replaces the rock aggregate component of the mixture. The material produces a structurally superior paving material and longer lived roadbed. The plastic may include any and all residual classes of recyclable plastic, including thermosetting plastics and other plastics having little to no current widespread utility. The material produces roadbeds of higher strength with less total asphalt thickness and having greater water impermeability, and is most useful for all layers below the surface layer. The recyclable plastic component of the material is preferably a mixture of all recyclable classes 3 through 7, or of those materials from such classes from which potentially more valuable recyclable materials have been selectively removed.

Abstract: An apparatus for efficiently heating a wafer within a CVD environment isolates the heating element of the apparatus from the CVD environment and includes a susceptor body defining a sealed space therein for containing the heating element and a surface coupled to the heating element for supporting and heating the wafer. The susceptor space is sealed from the CVD environment and is vacuumed to a first pressure. Heating gas is delivered through a space extending through the susceptor body which is sealed from the susceptor space containing the heating element and is vacuumed to a second pressure which is preferably less than the CVD reaction pressure to vacuum clamp a wafer to the susceptor. The heating gas delivery space is formed by an elongated sheath surrounding a hollow wafer lift tube and the sheath is sealed at one end to the backplane of the susceptor and at the other end to the tube. The wafer lift tube moves up and down within the sheath to lift a wafer.
