Patent number: 7181125Abstract: A device which is capable of storing moving picture data received from each terminal and providing each terminal with video information to be reproducible by rapidly forwarding or reversing at any desired speed independent of usable terminals. A video storage type communication device 30 with a receiving portion 35 and a transmitting portion 38 transmits and receives video data over a communication network 10 to and from each terminal 1–n. A coded video data received from terminals 1–n is stored as it is in a first storage portion 32 and, at the same time, the data converted into specially reproducible video information is stored in the second storage portion 33. At the time of reproducing, the reproduction control portion 35 controls the reproduction selector switch 36 to obtain the video data from the first storage portion 32 or the second storage portion 33, changing the reproduction mode from ordinary to the rapid forwarding/reversing and vice versa.Type: GrantFiled: January 9, 2002Date of Patent: February 20, 2007Assignees: Sharp K.K., Nippon Telegraph & Telephon CorporationInventors: Hirotaka Nakano, Osamu Nakamura, Youji Kanada, Tsuneko Kura, Takashi Oshima, Tadashi Uchiumi, Keiichi Hibi, Jiro Nakabayashi, Tsuneaki Iwano, Nobuyuki Ema

Patent number: 6487319Abstract: An apparatus and a method for identifying the spatial location of a coding unit, e.g., a texture unit (TU), in a hierarchically decomposed image. Specifically, the invention quickly computes and identifies the “starting point” of a texture unit, by using the texture unit number and the width and height of the “DC” band.Type: GrantFiled: August 19, 1999Date of Patent: November 26, 2002Assignees: Sarnoff Corporation, Sharp K. K.Inventor: Bing-Bing Chai

Patent number: 6078721Abstract: A device which is capable of storing moving picture data received from each terminal and providing each terminal with video information to be reproducible by rapidly forwarding or reversing at any desired speed independent of usable terminals. A video storage type communication device 30 with a receiving portion 35 and a transmitting portion 38 transmits and receives video data over a communication network 10 to and from each terminal l-n. A coded video data received from terminals l-n is stored as it is in a first storage portion 32 and, at the same time, the data converted into specially reproducible video information is stored in the second storage portion 33. At the time of reproducing, the reproduction control portion 35 controls the reproduction selector switch 36 to obtain the video data from the first storage portion 32 or the second storage portion 33, changing the reproduction mode from ordinary to the rapid forwarding/reversing and vice versa.Type: GrantFiled: October 1, 1997Date of Patent: June 20, 2000Assignees: Sharp K.K., Nippon Telegraph & Telephon CorporationInventors: Tadashi Uchimi, Keiichi Hibi, Jiro Nakabayashi, Tsuneaki Iwano, Nobuyuki Ema, Hirotaka Nakano, Osamu Hakamura, Youji Kanada, Tsuneko Kura, Takashi Oshima

Patent number: 6055332Abstract: A purpose of the handwriting recognition device is to retrieve handwritten characters and symbols at high speed and easily. The stroke data input from the stroke data input part through handwritten input is subjected to the approximate reforming process and single-stroking process to prepare the single-stroke data. By subjecting the single-stroke data to the complex Fourier transform process, the Fourier coefficient is obtained and the number of strokes is obtained. During registration, the dictionary Fourier coefficient and the dictionary stroke number, and the dictionary stroke data are stored in the dictionary memory in relation to each other. During retrieval, the retrieval Fourier coefficient and the retrieval stroke number are stored temporarily in the temporary memory. Furthermore, the dictionary stroke data are narrowed down according to the result of the comparison of the stroke numbers, and the dictionary stroke data is determined according to the result of the comparison of the Fourier coefficient.Type: GrantFiled: January 29, 1998Date of Patent: April 25, 2000Assignee: Sharp K.K.Inventors: Yasuhiro Aitani, Masashi Amano

Patent number: 6055151Abstract: Embedded passive components such as capacitors are formed in multilayer ceramic circuit boards by screen printing a component precursor compound ink sandwiched between conductor ink layers onto a green tape stack and covering the component ink layer with one or two green tape layers, aligning and laminating the green tapes and firing. Capacitor inks are made from dielectrics chosen from barium titanate, titanium oxide and lead-magnesium-niobate. The green tapes are made of a mixture of a crystallizing glass, a non-crystallizing glass and an oxide filler which does not shrink in the x and y dimensions during firing mounted on a metal support. Thus the embedded components can be made to close tolerances.Type: GrantFiled: February 27, 1998Date of Patent: April 25, 2000Assignees: Sarnoff Corp, Sharp K.K.Inventors: Ellen Schwartz Tormey, Ashok Narayan Prabhu, Attiganal Narayanaswamy Sreeram, Michael James Liberatore
