  • Patent number: 11994528
    Abstract: Purifying target biomolecules, such as nucleic acids or proteins, from a biological source is a time intensive process and is typically performed by a skilled technician or scientist owing to the highly technical nature of the work. Systems, devices, and methods disclosed herein enable the automated bioprocessing and purification of target biomolecules from a biological source. For example, an instrument and disposable cartridge are provided for automatedly isolating and purifying nucleic acids (such as plasmid DNA from a bacterial culture) or for isolating protein from any biological sample. Such an exemplary instrument and cartridge can work in concert to timely release, mix, and move the target biomolecule and various reagents and buffers through a target biomolecule purification process, resulting in a purified target biomolecule with less manual oversight than traditional approaches.

  • Patent number: 9324900
    Abstract: A method of fabricating a superlattice structure requires that atoms of a first III-V semiconductor compound be introduced into a vacuum chamber such that the atoms are deposited uniformly on a substrate. Atoms of at least one additional III-V compound are also introduced such that the atoms of the two III-V compounds form a repeating superlattice structure of alternating thin layers. Atoms of a surfactant are also introduced into the vacuum chamber while the III-V semiconductor compounds are being introduced, or immediately thereafter, such that the surfactant atoms act to improve the quality of the resulting SL structure. The surfactant is preferably bismuth, and the III-V semiconductor compounds are preferably GaSb along with either InAs or InAsSb; atoms of each material are preferably introduced using molecular beam epitaxy. The resulting superlattice structure is suitably used to form at least a portion of an IR photodetector.

  • Patent number: 9304342
    Abstract: A display device is provided that comprises a liquid crystal display panel (2) for displaying an image by spatial light modulation. The image is represented by a plurality of image elements each having an image data value (7). The display device further comprises a display controller (1) arranged to determine a signal voltage to be applied to the panel (2) for each image element in dependence upon its image data value (7) and a secondary data value (8) for the element, there being a predetermined mapping between the data values and the signal voltage. The secondary data values (8) are arranged to vary across the image so as to introduce variations in luminance as a result of the mapping. The mapping and secondary data values (8) are mutually arranged to take account of the signal voltage to on-axis luminance response of the panel (2) so that the luminance variations introduced on-axis tend to balance locally through spatial averaging to, and hence would not be perceivable by, an on-axis viewer (3).

  • Patent number: 9276159
    Abstract: A structure comprised of an InAsSb layer adjacent to a GaSb layer, with the adjacent InAsSb and GaSb layers repeating to form a superlattice (SL). The structure is preferably an unstrained SL, wherein the composition of the InAsSb layer is InAs0.91Sb0.09; the InAs0.91 Sb0.09 layers are preferably lattice-matched to the GaSb layers. The SL structure is preferably arranged such that the Sb component of the InAsSb layers reduces the strain in the SL structure so that it is less than that found in an InAs/GaSb Type-II Strained Layer Superlattice (SLS). The present SL structure is suitably employed as part of an infrared photodetector.
