  • Patent number: 10448030
    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.

  • Patent number: 10396240
    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: 10373830
    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: 10244223
    Abstract: A compressed light field imaging system is described. The light field 3D data is analyzed to determine optimal subset of light field samples to be (acquired) rendered, while the remaining samples are generated using multi-reference depth-image based rendering. The light field is encoded and transmitted to the display. The 3D display directly reconstructs the light field and avoids data expansion that usually occurs in conventional imaging systems. The present invention enables the realization of full parallax 3D compressed imaging system that achieves high compression performance while minimizing memory and computational requirements.

  • Patent number: 10134802
    Abstract: An emissive Solid State Imager (SSI) comprised of a spatial array of digitally addressable multicolor micro pixels. Each pixel is a micro optical cavity comprising multiple photonic layers of blue-violet semiconductor light emitting diode. One of the photonic layers is used to generate light at the blue primary of the SSI. Two of the photonic layers are used to generate violet-blue excitation light which is converted with associated nanophosphors layer into the green and the red primaries of the SSI. The light generated is emitted perpendicular to the plane of the imager device via a plurality of vertical optical waveguides that extract and collimate the light generated. Each pixel diode is individually addressable to enable the pixel to simultaneously emit any combination of the colors associated with its multicolor nanophosphors converted semiconductor light emitting diode at any required on/off duty cycle for each color.

  • Patent number: 10070115
    Abstract: An innovative method for synthesis of compressed light fields is described. Compressed light fields are commonly generated by sub-sampling light field views. The suppressed views must then be synthesized at the display, utilizing information from the compressed light field. The present invention describes a method for view synthesis that utilizes depth information of the scene to reconstruct the absent views. An innovative view merging method coupled with an efficient hole filling procedure compensates for depth misregistrations and inaccuracies to produce realistic synthesized views for full parallax light field displays.

  • Patent number: 9978582
    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.

  • Patent number: 9930272
    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.

  • Patent number: 9882526
    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.
