System for browsing a collection of information units

The invention relates to a system for browsing a collection of information units, such as audio or video files, comprising presentation means for presenting an information unit from said collection, and attribute means for associating a respective information unit with an attribute value for at least a first attribute. The system according to the invention randomly selects information units which meet certain criteria for said first attribute.

Lighting device

InactiveUS20020130326A1Optical output from the device can be kept constant for a long timeReduce the numberLight source combinationsElectric circuit arrangementsPhotovoltaic detectorsPhotodetector
A lighting device includes: a plurality of LEDs arranged in an at least two-dimensionally dispersed manner; a transparent resin layer that covers the plurality of LEDs in an integrated form; a photo-detecting unit that detects an intensity of light emitted from the plurality of LEDs using a photodetector, the photodetector being arranged inside, on a surface, or in the vicinity of the transparent resin layer; and a power supply circuit unit that controls driving of the plurality of LEDs based on a detection output from the photo-detecting unit. Here, the number of the photodetector is smaller than the number of the LEDs, and the photodetector detects an intensity of light emitted from the LEDs and propagated through the transparent resin layer.

Solid-state imaging device, method of manufacturing the same, and camera

A solid-state imaging device is provided. The solid-state imaging device includes a plurality of arrayed pixels, an optical inner filter layer, and an inner-layer lens. Each of the plurality of arrayed pixels includes a photoelectric conversion portion and a pixel transistor. The optical inner filter layer is configured to block infrared light and faces a light-receiving surface of the photoelectric conversion portion of a desired pixel among the arrayed pixels. The inner-layer lens is formed below the optical inner filter layer.

Method of generating a conforming hybrid grid in three dimensions of a heterogeneous formation crossed by one or more geometric discontinuities in order to carry out simulations

Method of generating a hybrid grid, in order to carry out simulations in accordance with a defined numerical scheme, in three dimensions and admissible in the numerical scheme sense, of a heterogeneous formation crossed by one or more geometric discontinuities such as, for example, an underground formation where one or more wells have been drilled, or a fractured formation, by combining structured grids and unstructured grids. The hybrid grid is achieved by associating a first structured grid for gridding the heterogeneous medium with second structured grids for gridding a zone around each discontinuity. A cavity of minimum size, allowing the cells of the transition grid to have an intermediate size between the size of the cells of the first grid and the size of the cells of the second grids, is first generated, entirely automatically. A transition grid meeting the constraints of the numerical scheme used for simulation is then constructed. Finally, the quality of the transition grid is improved by optimizing it under quality controls in the numerical scheme sense, in order to define a perfectly admissible transition grid in the sense of the numerical scheme selected. Applications: hydrocarbon reservoir simulators for example.

Lighting device, display device and television receiver

It is an object of the present invention to provide a lighting device realizing reduction in cost and suppression of power consumption and suppressing generation of a lamp image. A lighting device 12 of the present invention includes a plurality of point light sources 80; a chassis 14 housing the point light sources 80 and having an opening 14b through which light from the point light sources 80 exits; and an optical member 15 (15a) facing the point light sources 80 and provided to cover the opening 14b. The point light sources 80 are arranged such that a light source high-density area LH where an arrangement interval thereof is relatively small and a light source low-density area LL where an arrangement interval thereof is relatively large are provided. Light reflection portions 50 reflecting lights from the point light sources 80 are formed in at least a region overlapping with the light source low-density area LL in the optical member 15 (15a).
