摘要:
A hardware search structure quickly determines the status of cache lines associated with a large disk array and at the same time reduces the amount of memory space needed for tracking the status. The search structure is configurable in hardware to different cache line sizes and different primary and secondary index sizes. A maintenance feature invalidates state record entries based both on their time stamps and on associated usage statistics.

A gas turbine vane to improve vane performance by addressing known failure mechanisms. A cooling circuit to the trailing edge of a vane airfoil is fed from the outer diameter platform, which prevents failure due to an oxidized and eroded airfoil trailing edge. The gas turbine includes an outer diameter platform, a hollow airfoil and an inner diameter platform with a plurality of cooling tubes extending radially through the airfoil. The cooling tubes are open at the outer diameter end and closed with covers at the inner diameter end. The inner diameter platform is also cooled and includes a meterplate for a portion of the cooling passageway and includes an undercut to improve thermal deflections of the inner diameter platform.

A first aspect of the invention includes a power relay assembly having a motor assembly and actuator assembly disposed in a housing. The actuator assembly includes at least one bridge assembly having one or more contacts arranged to provide selective electrical connections. The actuator assembly is attached to an armature of the motor assembly. The armature is arranged and disposed to drive the actuator assembly. The motor assembly includes an electromagnetic coil assembly disposed around at least a portion of the armature. A magnetic pole piece is configured adjacent to an end of the coil assembly. The pole piece includes an armature seat configured to attract and receive the armature when the coil assembly is magnetized. The armature seat has a taper configured to provide a substantially constant attractive force along the stroke length.

A composite wood product and its method of manufacture. The wood product comprises aligned, substantially straight wood strands cut from veneer, disposed side by side lengthwise in substantially parallel relationship with adhesive bonding together the strands. The product is produced in a billet having a width in the range of about 3 ft. to 12 ft. and with a thickness in the range of about 1.1 inches to 2 inches. The strand ends are distributed in a specific pattern that approximates maximizing the minimum distance between strand ends. The wide sides of the billet are coated with a dark colored resin. The billet may be sawn lengthwise into sizes used for joists and rafters. Such a sawn product (e.g. 1.5″ by 9.25″) has the wide sides a dark resin color and the narrow sawn sides mostly wood colored. The strands are parallel to its length.

A data-processing system and method are disclosed, which include a cached processor for processing data, and a plurality of memory components that communicate with the cached processor. The cached processor is separated from the memory components such that the cached processor provides support for the memory components, thereby providing a diffused memory architecture with diffused memory capabilities. The memory components can constitute, for example, memory devices such as diffused memory, matrix memory, R-Cell memory components, and the like, depending on design considerations.

Systems, including compositions, kits, and methods, particularly for photoluminescence applications. The systems may include, among others, (1) organic chelators, (2) complexes between the chelators and lanthanide ions, and (3) precursors, derivatives, and uses thereof. The chelators may include a 1,4,7,10-tetraazacyclododecane ring system, for example, having the formula: Here, R1, R2, and R3 are substituents of the tetraazacyclododecane ring system, that is further substituted at the 10-position by a sensitizer Z that is typically a polyheterocyclic ring system. The organic chelator may be capable of forming a luminescent complex with a lanthanide ion, and is optionally further substituted by a reactive functional group or a conjugated substance. The resulting lanthanide complex may be useful in luminescence-based assays, such as energy transfer assays, among others.

A data-processing system and method include a processor core associated with a cache controller. A plurality of cached memory components is associated with the processor core and the cache controller. A cached processor is provided, which supports a plurality of varying sizes of instruction and data cache, wherein the cached processor comprises a processor core separated from the cache controller and the plurality of cached memory components, thereby permitted the cached processor to support varying sizes of cache memory in a flexible memory arrangement thereof.
