  • Patent number: 10776203
    Abstract: A data storage service stores a dataset on a set of storage nodes in accordance with a first encoding. A set of shards constituting quorum, and one or more additional shards, are stored on the storage nodes. The data storage system determines to store the dataset according to a second encoding, in which the second encoding has fewer total shards. The data storage system reconfigures the storage of the dataset in accordance with the second encoding, such that the reconfigured storage comprises subsets of shards from the first encoding that were not re-encoded in forming the second encoding.

  • Publication number: 20200064616
    Abstract: A system for obtaining a 3-D, super-resolution model of an object in an image space is provided as well as novel and nonobvious components thereof. The system includes a light source that constrains uninhibited activation light to a thin slice through the object, the object having a volume that is perpendicular to an axis of a 2-D super-resolution microscope, a means for providing relative incremental movement between the object and the thin slice of constrained uninhibited activation light, and a means for taking a super resolution picture of each incremental slice resulting from the relative incremental movement between the object and the thin slice, thereby creating a set of voxels from which an accurate 3-D super-resolution model of any fluorescent object contained within the image space can be constructed.

A set of shards constituting quorum, and one or more additional shards, are stored on the storage nodes. The data storage system determines to store the dataset according to a second encoding, in which the second encoding has a greater number of shards. The data storage system reconfigures the storage of the dataset in accordance with the second encoding, such that the reconfigured storage forms additional shards for the second encoding by combining portions of shards of the first encoding.

  • Publication number: 20190049789
    Abstract: The present disclosure generally relates to systems and methods for manufacturing wire grid polarizers for LCDs using interference lithography, which are also useful for generating large-area grating patterns. In one embodiment, a method includes depositing a bottom anti-reflective coating layer over an aluminum coated flat panel display substrate, depositing a photoresist layer over the bottom anti-reflective coating layer, and exposing the photoresist layer with an image from a phase grating mask. The exposure with the phase grating mask is done by imaging the ±1 diffraction orders from the phase grating mask onto the substrate using a half Dyson optical system. A plurality of half Dyson systems are generally used in parallel to pattern fine geometry lines and spaces of a wire grid polarizer for a large area substrate. Each half Dyson system includes a primary mirror, a positive lens and a reticle.

  • Patent number: 10162268
    Abstract: Implementations disclosed herein generally relate to a light pipe, or kaleido, for homogenizing light such that the light is uniform once the light exits the light pipe. By reflecting the light inside the light pipe, light uniformity is increased. In one implementation, a light pipe for an image projection apparatus is provided. The light pipe comprises an elongated rectangular body having a refractive index that provides total internal reflection within the elongated rectangular body. The elongated rectangular body has an input face for accepting light into the elongated rectangular body. The input face disposed substantially orthogonal to a longitudinal axis of the elongated rectangular body. The elongated rectangular body has an output face for releasing light from the elongated rectangular body. The output face is disposed substantially orthogonal to the longitudinal axis. The elongated rectangular body has a twist along the longitudinal axis.

  • Publication number: 20180017781
    Abstract: The present disclosure generally relates to frustrated cube assemblies having a first prism having a first surface, a second surface, and a first hypotenuse, and a second prism having a third surface, a fourth surface, and a second hypotenuse. The first and second hypotenuses face one another and are separated by an air gap. The frustrated cube assembly may include a tilted mirror adjacent the second surface. The second surface may be a reflective diffraction grating. Light is reflected to a digital micromirror device (DMD) adjacent to the frustrated cube assembly at a normal incidence angle and through an image projection system along a single optical axis. The direction of light incident on the DMD is such that light reflected from an “on” mirror is directed along the normal to the DMD surface and at 45 degrees to the hypotenuses. The input and output light beams are parallel.

  • Patent number: 9401278
    Abstract: Methods and apparatuses are provided for improving the intensity profile of a beam image used to process a semiconductor substrate. At least one photonic beam may be generated and manipulated to form an image having an intensity profile with an extended uniform region useful for thermally processing the surface of the substrate. The image may be scanned across the surface to heat at least a portion of the substrate surface to achieve a desired temperature within a predetermined dwell time. Such processing may achieve a high efficiency due to the large proportion of energy contained in the uniform portion of the beam.
