Patent number: 7742037Abstract: A detection section that detects a key-tapping speed and key-tapping intensity is provided to detect a user's impatience level. An input device detects the key-tapping intensity and key-tapping speed. The input device compares the detection value of the key-tapping speed and an average key-tapping speed. When the detection value exceeds a stored normal key-tapping speed, the input device then compares the detection value of the key-tapping intensity and a reference pressure value. When the detection value exceeds a stored normal key-tapping intensity, information to be output for a user is changed over. In this case, displayed characters are enlarged and emphasized to a maximum extent. On the other hand, in the case where a detection value does not exceed the normal key-tapping speed and the detection value exceeds the normal key-tapping intensity, displayed characters are only slightly enlarged.Type: GrantFiled: November 16, 2004Date of Patent: June 22, 2010Assignee: Sony CorporationInventors: Yoichiro Sako, Toshiro Terauchi, Makoto Inoue, Masamichi Asukai, Katsuya Shirai, Yasushi Miyajima, Kenichi Makino, Motoyuki Takai

Display apparatus for displaying text or images and outputting sounds based on text code information
Patent number: 7728826Abstract: In a display apparatus, a text code input section outputs externally-supplied text code information to a font conversion section and a voice synthesizer section. The font conversion section converts the input text code into a corresponding font, and transmits the font to a display drive section via a video signal input section, and the display drive section causes a display section to display the font. Meanwhile, the voice synthesizer section converts the input text code into corresponding voice data, and transmits the voice data to a voice device where the voice data is outputted. With this structure, superior convenience is ensured for a display apparatus which serves only as an individual displaying apparatus and relies on an external device (server) for the major functions of the system.Type: GrantFiled: December 27, 2004Date of Patent: June 1, 2010Assignee: Sharp Kabushiki KaishaInventor: Kazuhiko Miyata -
Patent number: 7701426Abstract: In each horizontal period, by switching ON switches respectively provided for three data signal lines for R, G and B in a group at the same time only in a predetermined period, the data signal lines in the group are preliminary charged to a predetermined potential at the same time before a data signal supply period. In a subsequent data signal supply period, respective switches of data signal lines for R, G and B are switched ON sequentially, to sequentially supply respective data for R, G and B to pixels on a scanning signal line as selected are supplied via data signal lines. As a result, in a display device driven by time-division based on a group of sequentially provided data signal lines, it is possible to suppress up-throw potential fluctuations when display.Type: GrantFiled: September 15, 2004Date of Patent: April 20, 2010Assignee: Sharp Kabushiki KaishaInventors: Makoto Yokoyama, Hajime Washio, Yuhichiroh Murakami, Etsuo Yamamoto
