  • Patent number: 10819973
    Abstract: Disclosed herein are head-mounted displays comprising a display screen and an optics block. The optics block is configured to present, at a time instant, to a left eye of a user of the head-mounted display apparatus, a first shifted version all of an image generated by the display screen. The first shifted version of the image has a first perceived center location that differs from the center of the display screen. The optics block is also configured to present, at the time instant, to a right eye of the user of the head-mounted display apparatus, a second shifted version of the image generated by the display screen, the second shifted version of the image having a second perceived center location that differs from the center of the display screen and that differs from the first perceived center location.

  • Patent number: 10782525
    Abstract: The present invention is directed to devices, systems and methods for coordinating water-related experiences with virtual reality content. In one aspect of the present invention, a method of providing a virtual reality experience to a rider moving along the surface of water is provided. The method includes the following steps: providing a headset to the rider, wherein the headset is placed over the rider's eyes; providing a surface of water along which the rider can travel; collecting data on the rider's acceleration, velocity or orientation through interaction of the headset with signals generated next to the surface of the water along which the rider travels; using the data to calculate one or more values that are used to coordinate virtual reality content with the rider's position along the water surface; presenting the virtual reality content to the rider through the headset, thereby providing a virtual reality experience to the rider.

  • Publication number: 20200158622
    Abstract: In flow cytometry, particles (2) can be distinguished between populations (8) by combining n-dimensional parameter data, which may be derived from signal data from a particle, to mathematically achieve numerical results representative of an alteration (48). An alteration may include a rotational alteration, a scaled alteration, or perhaps even a translational alteration. Alterations may enhance separation of data points which may provide real-time classification (49) of signal data corresponding to individual particles into one of at least two populations.

  • 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.

  • Patent number: 9058788
    Abstract: A method of processing image data for display by a display panel of a display device is provided. The method comprises receiving main image pixel data representing a main and side image pixel data representing a side image. In a first processing step, a mapping is performed of the pixel data to signals used to drive the display panel. The mapping is arranged to produce an average on-axis luminance which is dependent mainly on the main image pixel data and an average off-axis luminance which is dependent at least to some extent on the side image pixel data. In a second processing step, the received side image pixel data are processed to emphasize at least one feature of the side image which might otherwise be perceived by a viewer as being de-emphasized in the side image displayed off axis as a result of the first processing step.

  • Patent number: 8896507
    Abstract: A liquid crystal device comprises an active matrix substrate (6) and a counter-substrate (7) provided with homeotropic alignment surfaces (11). A layer of nematic liquid crystal material is provided between the alignment surfaces (11) so as to form a vertically aligned nematic device. The substrates (6, 7) carry a pixel electrode arrangement and a counter-electrode arrangement which define a plurality of pixel regions. Each of least some of these regions has a pixel electrode (13), which may be split into two halves, and a counter-electrode (8) which are arranged to apply an electric field for controlling the liquid crystal director (12) out-of-plane tilt angle. A further electrode (14), for example in the form of a plurality of parallel fingers, cooperates with at least one of the other electrodes (8, 13) to apply a second electric field for controlling the director in-plane azimuth angle. Such a device may be used, for example, as a switchable public/private display.
