摘要： This document describes, in various implementations, features related to receiving, at a storage system that includes a storage volume and a plurality of storage devices that operate separately from the storage volume, read requests directed to data stored on the storage volume. The document also describes replicating certain data stored on the storage volume to the storage devices such that read requests associated with the certain data are fulfilled either by the storage volume or by the storage devices. The document also describes determining first usage information that is indicative of actual or expected usage of the storage system at a first time, and powering down at least one of the storage devices based on the first usage information.

摘要： A liquid crystal light valve is provided with an array of photoconductive pedestals surrounded by a dielectric matrix material. Metal mirror pads are formed on top of each pedestal to form a high resolution metal matrix mirror, with each pedestal/mirror combination servicing one image pixel. The dielectric matrix forms a potential barrier between the individual photoconductive pedestals which prevents lateral charge migration between pedestals. The metal matrix mirror also shields the underlying photoconductive pedestal from photoactivation by the readout beam. The dielectric matrix material has a lower dielectric constant than the photoconductive pedestals, allowing the impedance of the photoconductive pedestals to match the impedance of the liquid crystal layer with a much thinner layer of photoconductive material than in prior LCLVs using a continuous photoconductive layer. The thinner photoconductive layer results in higher electric fields which improve the LCLV's response time, photodegradation rate, spatial resolution and spectral response.

摘要： A liquid crystal (LC) display method and apparatus applies respective active LC bias voltages to both a master LC cell, and a phase compensation LC cell for the master cell. The bias voltages are selected to reduce the response time of the master cell, and to establish a common multicolor dark state for that cell. With a proper selection of the bias voltages, the products of the liquid crystal thickness and birefringence for each cell are substantially equal and mutually cancel. A bias voltage is first established for one cell, and the bias voltage for the other cell is then scanned to locate the point of mutual cancellation. A range of different bias voltages are possible, and a suitable bias is selected to balance response time against the required operating voltage range. A multicolor display system using only a single light valve can be realized.

摘要： Provided is a system for detecting moving objects. The system includes a video capturing device and a detection unit. The video capturing device captures “n” pieces of consecutive images during a time period, where “n” represents a positive integer. The detecting unit selects one of the images as a reference images and processes the other n−1 pieces of images. The detecting unit differentiates the n−1 pieces of images relative to the reference image, grays the differentiated n−1 pieces of images, binarizes the grayed n−1 pieces of imaged, blurs the binarized n−1 pieces of images, dilates the blurred n−1 pieces of images, and detects edges from the dilated n−1 pieces of images.

摘要： A flicker detecting apparatus for a camera module includes a processor. The processor includes a brightness values reading module, a calculating module, and a determining module. The brightness values reading module reads out a number of brightness values from a number of pixels of pictures captured by the camera module. The calculating module calculates out brightness values differences between the pixels. The determining module compares the brightness values differences with a preset value to determine whether the camera module is acceptable.

摘要： The angular and/or spectral bandwidth of a holographic lens assembly can be widened to accomodate highly diverging and/or wide spectral bandwidth illumination sources, respectively. Each lens in the lens assembly is comprised of a plurality of angularly customized holograms (an angularly customized hologram set). Each of the individual holograms in an angularly customized hologram set has an acceptance angle range that is centered on a discrete peak acceptance angle. The separation between the holograms' peak acceptance angles is chosen so that the acceptance angle ranges of the individual holograms overlap. The resulting cumulative acceptance angle range of each angularly customized hologram set provides a holographic lens assembly that has a wider angular bandwidth than prior holographic lenses. The spectral bandwidth of the lens assembly can be similarly widened by adding a spectrally customized hologram set to the lens assembly in which the spectral waveband of each of the individual spectrally customized holograms partially overlap. Specific applications to various types of displays are disclosed, as well as preferred fabrication techniques for the holographic lenses.
