摘要： A wearable display device includes a visual access operating system (vuOS) that can interface with multiple computing platforms. The vuOS enables concurrent visual interface between the multiple computing platforms and a user and performs context switching between the multiple computing platforms in response to either a computing platform visual access request or a user's selection prompt. The multiple computing platforms are each assigned a user selected visual access slot that occupies a selected segment of the user field of view (FOV) visually accessible by the wearable display system. At any given time one of the multiple computing platforms visual access slots is brought onto the user's gaze zone in the FOV while some of the other computing platforms visual access slots are assigned to the peripheral vision zone and other computing platforms are assigned visual access attention request access slots displayed at a visual attention zone within the user's viewable portion of the wearable display FOV. The wearable display vuOS further allocates to each of the multiple computing platforms a physical interface connection having an interface throughput that is commensurate with their assigned visual slot size and position within the user field of view (FOV) visually accessible by the wearable display system.

摘要： 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.

摘要： 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.

摘要： A backflow liner in an epitaxial growth system is provided in order to control gas flow and protect the surface of substrates throughout an epitaxial growth cycle. The backflow liner provides critical protection during the warming time prior to substrate pre-treatment, while the growth environment reaches steady state condition between the pre-treatment and the growth process, during pauses between the layer depositions in case of multilayer structure growth, and during the cooling process. The direction of the gas flow through the backflow liner is counter to the deposition gas flows directed from the source end of the growth system. The backflow liner is therefore designed to shape the flow of gases to prevent formation of the vortex-type streams in the growth system that may negatively affect the growth process.

摘要： A video display system is described which is formed by an array of pixels comprised of fast responding light elements, row select and column select switches and pixel data drivers, and a computation subsystem which generates the control signals for the select lines and the video data. The overall system reconstructs the intended image or video to be displayed through successively displaying subframes of images corresponding to orthogonal image basis function components of the original image acting on a grouping of pixels selected using multiple row and column lines. The resultant system is an architecture which enables one to implement certain video decompression techniques directly on the light elements, as opposed to implementing these techniques in digital processing, and can have a considerably reduced raw video data requirement than a system in which pixels are addressed individually, and enables higher dynamic range to be achieved with similar digital-analog-converter specifications. Embodiments with LED based displays are described herein.
