  • Publication number: 20150278237
    Abstract: A file selection system includes a terminal and an information processor. The terminal transmits, to the information processor, files and usage history records each including information on a file use position at which a corresponding one of the files was used. The information processor receives the files and the usage history records transmitted from the terminal, and determines, based on each of the usage history records, a place with a spatial extent including the file use position. The information processor manages each of the files in association with the corresponding place. Then, the information processor selects files according to one or more places to which the terminal is scheduled to move, and transmits the selected files to the terminal.

  • Patent number: 7497609
    Abstract: An illuminating device comprises a pair of light sources and a rod-like photoconductor. The rod-like photoconductor includes a pair of planes of incidence entered by the light from the light sources, a reflection surface having a plurality of prisms and an exit plane located opposite to the reflection surface. The width between the reflection surface and the exit plane at the planes of incidence of the rod-like photoconductor is smaller than the width of the light sources in the same direction. As a result, the brightness distribution of the light exiting from the rod-like photoconductor becomes uniform. The illuminating device is combined with a plate-like photoconductor to make up a planar illuminating device. Also, the illuminating device is combined with a liquid crystal panel to make up a liquid crystal display apparatus.

  • Patent number: 7489304
    Abstract: A substrate made of glass serves both as a substrate for a touch panel and as that for a front light, and has both functions of propagating an ultrasonic wave in order to detect a touched position, and propagating light emitted from a light source to guide the light toward a reflective-type liquid crystal display. In the case where an image on the liquid crystal display is made visible by external light, external light which has been transmitted through the substrate is reflected by the liquid crystal display, and the reflected light is again transmitted through the substrate to be emitted from the front face. In the case where the front light function is used, light which has been introduced into the substrate from the light source is reflected by the liquid crystal display, and the reflected light is transmitted through the substrate to be emitted from the front face.
