  • Patent number: 9774800
    Abstract: Spatio-temporal light field cameras that can be used to capture the light field within its spatio temporally extended angular extent. Such cameras can be used to record 3D images, 2D images that can be computationally focused, or wide angle panoramic 2D images with relatively high spatial and directional resolutions. The light field cameras can be also be used as 2D/3D switchable cameras with extended angular extent. The spatio-temporal aspects of the novel light field cameras allow them to capture and digitally record the intensity and color from multiple directional views within a wide angle. The inherent volumetric compactness of the light field cameras make it possible to embed in small mobile devices to capture either 3D images or computationally focusable 2D images. The inherent versatility of these light field cameras makes them suitable for multiple perspective light field capture for 3D movies and video recording applications.

  • Publication number: 20170263457
    Abstract: An electromagnetic wave irradiation apparatus and methods to bond unbonded areas in a bonded pair of substrates are disclosed. The unbonded areas between the substrates are eliminated by thermal activation in the unbonded areas induced by electromagnetic wave irradiation having a wavelength selected to effect a phonon or electron excitation. A first substrate of the bonded pair of substrates absorbs the electromagnetic radiation and a portion of a resulting thermal energy transfers to an interface of the bonded pair of substrates at the unbonded areas with sufficient flux to cause opposite sides the first and second substrates to interact and dehydrate to form a bond (e.g., Si—O—Si bond).

  • Patent number: 9722533
    Abstract: Designs of extremely high efficiency solar cells are described. A novel alternating bias scheme enhances the photovoltaic power extraction capability above the cell band-gap by enabling the extraction of hot carriers. When applied in conventional solar cells, this alternating bias scheme has the potential of more than doubling their yielded net efficiency. When applied in conjunction with solar cells incorporating quantum wells (QWs) or quantum dots (QDs) based solar cells, the described alternating bias scheme has the potential of extending such solar cell power extraction coverage, possibly across the entire solar spectrum, thus enabling unprecedented solar power extraction efficiency. Within such cells, a novel alternating bias scheme extends the cell energy conversion capability above the cell material band-gap while the quantum confinement structures are used to extend the cell energy conversion capability below the cell band-gap.

  • Publication number: 20170184776
    Abstract: Emissive micro-pixel spatial light modulators with non-telecentric emission are introduced. The individual light emission from each multi-color micro-scale emissive pixel is directionally modulated in a unique direction to enable application-specific non-telecentric emission pattern from the micro-pixel array of the emissive spatial light modulator. Design methods for directionally modulating the light emission of the individual micro-pixels using micro-pixel level optics are described. Monolithic wafer level optics methods for fabricating the micro-pixel level optics are also described. An emissive multi-color micro-pixel spatial light modulator with non-telecentric emission is used to exemplify the methods and possible applications of the present invention: ultra-compact image projector, minimal cross-talk 3D light field display, multi-view 2D display, and directionally modulated waveguide optics for see-through near-eye displays.

  • Publication number: 20170176744
    Abstract: Split exit pupil (or split eye-box) heads-up display (HUD)systems and methods are described. The described HUD system methods make use of a split exit pupil design method that enables a modular HUD system and allows the HUD system viewing eye-box size to be tailored while reducing the overall HUD volumetric aspects. A HUD module utilizes a high brightness small size micro-pixel imager to generate one or more HUD virtual images with a one or a plurality of given viewing eye-box segment sizes. When integrated together into a HUD system, a multiplicity of such HUD modules displaying the same image would enable such an integrated HUD system to have an eye-box size that is substantially larger than the eye-box size of a HUD module. The resultant integrated HUD system volume is substantially volumetrically smaller than a HUD system that uses a single larger imager.

  • Publication number: 20170178891
    Abstract: A method to improve the planarity of a semiconductor wafer and an assembly made from the method. In a preferred embodiment of the method, a compressive PECVD oxide layer such as SiO2 having a predetermined thickness or pattern is deposited on the second surface of a semiconductor wafer having an undesirable warp or bow. The thickness or pattern of the deposited oxide layer is determined by the measured warp or bow of the semiconductor wafer. The compressive oxide layer induces an offsetting compressive force on the second surface of the semiconductor wafer to reduce the warp and bow across the major surface of the semiconductor wafer.

  • Publication number: 20170170363
    Abstract: A method for growing on a substrate strongly aligned uniform cross-section semiconductor composite nanocolumns is disclosed. The method includes: (a) forming faceted pyramidal pits on the substrate surface; (b) initiating nucleation on the facets of the pits; and; (c) promoting the growth of nuclei toward the center of the pits where they coalesce with twinning and grow afterwards together as composite nanocolumns. Multi-quantum-well, core-shell nanocolumn heterostructures can be grown on the sidewalls of the nanocolumns. Furthermore, a continuous semiconductor epitaxial layer can be formed through the overgrowth of the nanocolumns to facilitate fabrication of high-quality planar device structures or for light emitting structures.

  • Publication number: 20170142427
    Abstract: A compression method for high-resolution light field display is disclosed for applications in which computer memory constraints and latency are critical. The disclosed compression algorithm takes advantage of the 3D structure of a light field to compress the raw light field information with a fixed compression ratio and simple decoding instructions. The compressed high-resolution light field achieves a reduced bandwidth with acceptable quality, and is packed in a way that can be transmitted using common interfaces. In a preferred embodiment, the compression algorithm is used as a post-processing stage after light field information acquisition or after rendering. In a further preferred embodiment, the compression algorithm is incorporated into the acquisition or rendering procedure to reduce memory and rendering processing. These and further embodiments generate a compressed light field with all information required for direct display.

    Abstract: A wearable system with a gestural interface for wearing on, for instance, the wrist of a user. The system comprises an ultrasonic transceiver array structure and may comprise a pico projector display element for displaying an image on a surface. User anatomical feature inputs are received in the form of ultrasound signals representative of a spatio-temporal cross-section of the wrist of the user by articulating wrist, finger and hand postures, which articulations are translated into gestures. Inputs from inertial and other sensors are used by the system as part of the anatomical feature posture identification method and device. Gestures are recognized using a mathematically-modeled, simulation-based set of biological metrics of tissue objects, which gestures are converted to executable computer instructions. Embodiments of the system disclosed herein may also be used to monitor biometric and health data over computer networks or using onboard systems.

  • Publication number: 20170104128
    Abstract: A III-nitride semiconductor light emitting device incorporating n-type III-nitride cladding layers, indium containing III-nitride light emitting region, and p-type III-nitride cladding layers. The light emitting region is sandwiched between n- and p-type III-nitride cladding layers and includes multiple sets of multi-quantum-wells (MQWs). The first MQW set formed on the n-type cladding layer comprises relatively lower indium concentration. The second MQW set comprising relatively moderate indium concentration. The third MQW set adjacent to the p-type cladding layer incorporating relatively highest indium concentration of the three MQW sets and is capable of emitting amber-to-red light. The first two MQW sets are utilized as pre-strain layers. Between the MQW sets, intermediate strain compensation layers (ISCLs) are added. The combination of the first two MQW sets and ISCLs prevent phase separation and enhance indium uptake in the third MQW set.

  • Patent number: 9524682
    Abstract: In the dynamic gamut display systems, video input data is processed to extract metrics indicative of the gamut occupancy of the frame pixels. The extracted metrics are used to form a set of scale factors to be used by the display to synthesize an adapted gamut that matches the frame pixel color gamut from the native color primaries of the display. The generated gamut adaptation scale factors are used to convert the frame pixels' values to the adapted gamut which are provided to the display for modulation using the synthesized adapted gamut for each video frame or a sub-region of a video frame. The methods enable increased display brightness, reduced power consumption and reduced interface and processing bandwidth. Also disclosed is an adapted video frame data formatting method that maps the benefits of the adapted gamut into a reduced frame data size enabling bandwidth savings when used for video distribution.
