摘要： A method of performing HVPE heteroepitaxy comprises exposing a substrate to a carrier gas, a first precursor gas, a Group II/III element, and ternary-forming gasses (V/VI group precursor), to form a heteroepitaxial growth of a binary, ternary, and/or quaternary compound on the substrate; wherein the carrier gas is H2, wherein the first precursor gas is HCl, the Group II/III element comprises at least one of Zn, Cd, Hg, Al, Ga, and In; and wherein the ternary-forming gasses comprise at least two or more of AsH3 (arsine), PH3 (phosphine), H2Se (hydrogen selenide), H2Te (hydrogen telluride), SbH3 (hydrogen antimonide, or antimony tri-hydride, or stibine), H2S (hydrogen sulfide), NH3 (ammonia), and HF (hydrogen fluoride); flowing the carrier gas over the Group II/III element; exposing the substrate to the ternary-forming gasses in a predetermined ratio of first ternary-forming gas to second ternary-forming gas (1tf:2tf ratio); and changing the 1tf:2tf ratio over time.

摘要： A wing, a method of controlling lift on a wing, and a system to produce lift on a wing are provided. The wing may include a fore-element, an aft-element, a pivotable linkage that operatively connects the aft-element leading edge to the fore-element trailing edge in a span-wise direction, and an actuator. The actuator may deflect the aft-element through a predetermined deflection angle about the pivotable linkage relative to the fore-element within less than or equal to two convective periods. The method may include deflecting a span-wise flap through the deflection angle in less than or equal to two convective periods to produce high lift. The system may include a sensor to detect an input and a controller to deflect the span-wise flap of the wing by the deflection angle in not more than two convective periods based on the received input signal.

摘要： The present invention relates to a resident space object orbit determination system comprising a high efficiency module for determining a resident space object's orbit and a highly efficient method for determining same. Applicants developed a method and system to determine the orbits of residence space objects including resident space objects that do not reflect energy that is directed at them and/or may be coated to minimize the ability to accurately see such resident space objects. Thus, a method, a module and a system for making such determinations that can easily and inexpensively be added to an early warning reentry system is provided.

摘要： A semiconductor structure configured to implement an optically controlled field effect transistor (FET). In one embodiment, a normally-off, optically controlled FET is realized as a semiconductor structure comprising various regions configured to implement a voltage controlled, normally on, high voltage FET region having integrated thereon a photoconductive region configured to reduce a gate-to-source voltage of the FET in response to light incident upon the photoconductive region so as to turn the FET on.

摘要： The present invention relates to ultrafast laser inscribed structures for signal concentration in focal plan arrays, focal plan arrays, imaging and/or sensing apparatuses comprising said focal plan arrays, as well as methods of making and/or using ultrafast laser inscribed structures for signal concentration in focal plan arrays, focal plan arrays, imaging and/or sensing apparatuses comprising said focal plan arrays. Such ultrafast laser inscribed structures are particularly adapted to condense broad band radiation, thus allowing increased sensing efficiencies to be obtained from imaging and/or sensing apparatuses. Such ultrafast laser inscribed structures can be efficiently produced by the processes provided herein.

摘要： A decoder for the MIL-STD-1553B bus which operates at a slower clock rate than the 40 MHz industry standard clock rate. This embodiment uses a 10 MHz clock rate. Because the clock rate is slower than the 40 MHz clock rate, the invention will inherently use less power. Additional features of this invention include: flexible resolution timestamp input, error checking and reporting throughout the decode process and 32 bit buffered parallel output of the bus controller and remote terminal communication. In another embodiment the decoder has a plurality of n ancillary clocks which provide partial state timestamps, which are summable to create a system timestamp.

摘要： A method of detecting and identifying pathogens in a sample comprising a plurality of genetic sequences. A plurality of electronic sequence reads corresponding to the plurality of genetic sequences is received and sampled to form a sample set. The sample set is iteratively and electronically compared to a plurality of pathogen sequences to create a detection group, which populates a putative genome data structure. A distance score is measured between each electronic sequence read of the sampled set to each pathogen sequence of the putative genome data structure. A hit score is calculated by comparing the distance score to a threshold value. A plurality of clusters of the electronic sequence reads of the sample set is formed to maximize the cluster hit score and to minimize a difference in distance scores of the cluster. A respective taxonomic group assigned to electronic reads of the sample set after clustering is displayed.
