  • Patent number: 8552417
    Abstract: The present application provides a light-emissive nitride nanoparticle, for example a nanocrystal, having a photoluminescence quantum yield of at least 1%. This quantum yield is significantly greater than for prior nitride nanoparticles, which have been only weakly emissive and have had poor control over the size of the nanoparticles produced. The nanoparticle includes at least one capping agent provided on a surface of the nitride crystal and containing an electron-accepting group for passivating nitrogen atoms at the surface of the crystal. The invention also provides non-emissive nitride nanoparticles.

  • Patent number: 8554517
    Abstract: Physiological signal quality classification methods and systems for ambulatory monitoring. Physiological signals are classified as good, noisy or weak based on signal properties. Once classified, signals are processed differently depending on their classification For example, for a good signal, physiological data may be extracted from the signal and displayed to a person being monitored. For a noisy signal, a noisy signal notification may be displayed to the person in lieu of extracted physiological data. For a weak signal, a weak signal notification may be displayed to the person in lieu of extracted physiological data. Moreover, a noisy or weak signal notification displayed to a person being monitored may be accompanied by a corrective action recommendation, such as “move to quieter environment” for a noisy signal or “check body placement of sensor” for a weak signal.

  • Patent number: 8553299
    Abstract: An image processing apparatus includes a two color process section and a color material usage estimation and calculation section. The two color process section generates, based on input image data of RGB inputted by reading an original document, image data of CMY for outputting a two-color image. The color material usage estimation and calculation section calculates, based on the image data of CMY generated by the two color process section, a usage of color materials used when the two-color image is outputted and generates information concerning the usage of color materials from a result of the calculation. The color material usage estimation and calculation section outputs the generated information concerning the usage of color materials to an image display device.

  • Patent number: 8555084
    Abstract: A data encryption device performs high-speed access to an arbitrary page when encrypting data and writing it to a storage device that can be accessed in a page unit or reading data therefrom and decrypting it. The device: encrypts data and writes it to the storage device or reads data from the storage device and decrypts it by a stream cipher; uses a counter mode of a block cipher to generate pseudorandom number series; specifies a data position in the storage device based on a page number and a page block number, by dividing one page into plural page blocks having a block length of the block cipher; and uses a value determined by a function of the page number, the page block number, and an arbitrary offset value, as an initial value of a pseudorandom number to be used in the counter mode.

  • Publication number: 20130257846
    Abstract: A memory-type liquid crystal display device includes transistors (N1, N2), retention electrodes (MRY), refresh output control sections (RS1), and capacitors (Cb1). In a data retention period, an electric potential of each of the retention electrodes (MRY) is changed via a corresponding one of the capacitors (Cb1) by changing an electric potential level of a retention capacitor wire signal that is supplied to a corresponding CS line (CSL(i)). Each of the refresh output control sections (RS1) receives the electric potential thus changed of a corresponding one of the retention electrodes (MRY) via the input section and controls an electric potential of a corresponding pixel electrode (PIX) in accordance with the electric potential thus changed.
