A hybrid LUN copy operation that ultimately produces a full LUN copy, but involves a transient snapshot-copy-like intermediate stage. In one embodiment, a statically pre-allocated copy LUN is initialized with references pointing back to the primary LUN. Over time, the sectors, blocks, or other data-storage units of the primary LUN are copied to the copy LUN, so that, in the end, a full copy LUN in completed. In a second, alternative embodiment, both the primary LUN and copy LUN are READ and WRITE accessible immediately following the nearly instantaneous initialization of the copy LUN. In both embodiments, the copy LUN may be statically allocated. The immediate-full-LUN-copy operations provided by the present invention further enable rotatable copy-LUN groups, each copy LUN within a copy-LUN group representing a full, robust copy LUN.

A mail sorter, which can reliably sort mail while avoiding the breakage and the recovery mistake of mail released from conveyor baskets, which move on the mail sorting line in circulation. The mail sorter has a conveyor line with a conveying forward run and a conveying return run closely arranged back to back with each, and layered mail recovery box groups are disposed along a lower region of the conveying return run in parallel to each other. The mail recovery box groups comprise lowest stage boxes for recovering mail M released from conveyor baskets on the conveying forward run through a transverse deflection chute, middle stage boxes for recovering mail M released from the conveyor baskets on the conveying forward run through a discharge chute, and uppermost stage boxes for recovering mail M released from the conveying baskets on the conveying return run through a buffer chute.

A duplexer has an asymmetrical antenna port and a symmetrical reception output, and therefore can be interconnected (without any intermediate stages) to an amplifier with a differential input. A reception bandpass filter is arranged in the reception path of the duplexer. The reception bandpass filter can have the functionality of a balun. The transmission input of the duplexer can be designed symmetrically, in which case a transmission bandpass filter arranged in the transmission path should be designed symmetrically on the input side. The impedance of the antenna port of the duplexer can differ from the impedance of the reception output or the transmission input. No intermediate stages (such as a balun or—in cases of impedances that differ between the duplexer and its corresponding amplifier—an impedance transformer) are required between the duplexer and the amplifier that is interconnected (whether before or after) in the transmission or reception path.

An airfoil (30) having a continuous layer of ceramic matrix composite (CMC) material (34) extending from a suction side (33) to a pressure side (35) around a trailing edge portion (31). The CMC material includes an inner wrap (36) extending around an inner trailing edge portion (38) and an outer wrap (40) extending around an outer trailing edge portion (42). A filler material (44) is disposed between the inner and outer wraps to substantially eliminate voids in the trailing edge portion. The filler material may be pre-processed to an intermediate stage and used as a mandrel for forming the outer trailing edge portion, and then co-processed with the inner and outer wraps to a final form. The filler material may be pre-processed to include a desired mechanical feature such as a cooling passage (22) or a protrusion (48). The filler material may include an upper layer (77) and a lower layer (78) separated by an intermediate layer (76) that extends to between the inner wrap and the outer wrap along the suction and/or pressure sides.

Submerged combustion systems and methods of use to produce foamed glass. One system includes a submerged combustion melter having an outlet, the melter configured to produce an initial foamy molten glass having a density and comprising bubbles filled primarily with combustion product gases. The initial foamy molten glass is deposited directly onto or into a transport apparatus that transports the initial foamy molten glass to a downstream processing apparatus. An intermediate stage may be included between the melter and the transport apparatus. One intermediate stage is a channel that includes gas injectors. Another intermediate stage is a channel that produces an upper flow of a less dense glass and a relatively more dense glass lower flow. The upper flow may be processed into foamed glass products, while the more dense flow may be processed into dense glass products.

A switch that selectively changes radio frequency signals includes at least three FETs, which are connected in series. The source electrodes or drain electrodes arranged at an intermediate stage have a width narrower than that of the source electrodes or the drain electrodes arranged at the initial and final stages. It is thus possible to lower the parasitic capacitance to ground at the intermediate stage and to thereby realize the switch having a high handling power.

A power amplifier is configured to operate in a first gain mode and a second gain mode. A first power amplifier input stage has an input and an output. A second power amplifier input stage has an input and an output, where the output of the second power amplifier input stage is coupled to the output of the first power amplifier input stage. The first input stage is turned on in response to a first bias voltage in the first gain mode and the second input stage is turned on in response to a second bias voltage in the second gain mode. Alternatively, a first input stage and an intermediate stage can be switched off by turning off their respective bias voltages, and a second input stage can be switched on by turning on its respective bias voltage; the intermediate stage and the second input stage sharing a common output.

An interface between synchronous and asynchronous data transfer includes a plurality of stages coupled to each other to form a pipeline for data transfer. The plurality of stages include a first stage which performs synchronous to asynchronous data transfer, at least one intermediate stage which performs asynchronous to asynchronous data transfer and a last stage which performs asynchronous to synchronous data transfer. A synchronous clock path propagates a timing signal across the plurality of stages to enable the first and last stages to perform operations when the timing signal is present at that stage.

A method and apparatus for partitioning a data set for clustering, based on the physical properties of an inhomogeneous ferromagnet. No assumption is made regarding the underlying distribution of the data. A Potts spin is assigned to each data point and an interaction between neighboring points is introduced, whose strength is a decreasing function of the distance between the neighbors. This magnetic system exhibits three phases. At very low temperatures it is completely ordered; i.e. all spins are aligned. At very high temperatures the system does not exhibit any ordering and in an intermediate regime clusters of relatively strongly coupled spins become ordered, whereas different clusters remain uncorrelated. This intermediate phase is identified by a jump in the order parameters. The spin-spin correlation function is used to partition the spins and the corresponding data points into clusters.

A process of producing an aluminum alloy sheet product suitable for forming into automotive parts and exhibiting reduced roping effects. The process involves producing an aluminum alloy sheet product by direct chill casting an aluminum alloy to form a cast ingot, homogenizing the ingot, hot rolling the ingot to form and intermediate gauge product, cold rolling the intermediate gauge product to form a product of final gauge, and subjecting the final gauge product to a solutionizing treatment by heating the product to a solutionizing temperature, followed by a pre-aging step involving cooling the product to a coiling temperature above 50 DEG C., coiling the cooled product at the coiling temperature, and cooling the coiled final gauge product from the coiling temperature above 50 DEG C. to ambient temperature at a rate less than about 10 DEG C. per hour to improve T8X temper characteristics of the product. Additionally, a batch anneal step is carried out on the intermediate gauge product or at an intermediate stage of the cold rolling to reduce or eliminate roping tendencies of the alloy sheet product. To maintain a high T8X response, the alloy used in the process has the following composition: 0.4 to 1.1% by weight magnesium; 0.3 to 1.4% by weight silicon; 0 to 1.0% by weight copper; 0 to 0.4% by weight iron; 0 to 0.15% by weight manganese; 0 to 0.15% weight naturally-occurring impurities (collective total); and the balance aluminum. The invention also relates to a sheet alloy product exhibiting reduced roping effects produced by the indicated process.
