Patent number: 6961338Abstract: A demultiplexer for separating different format packets from a multiplexed data stream. Each packet format has a different type of header which is analyzed based on micro-codes read out in sequence from a command memory. By using micro-codes, the demultiplexer minimizes the circuitry required to process multiple formats (e.g. digital video broadcasting (DVB), digital satellite system (DSS), and digital versatile disc (DVD)). The packets are separated and sent to their respective destinations based on the packet ID read from each header.Type: GrantFiled: April 23, 2001Date of Patent: November 1, 2005Assignee: Sony CorporationInventors: Hideki Nabesako, Osamu Yagi

Patent number: 5515287Abstract: A navigation supporting display apparatus makes it easy for an operator of ship to navigate with a safe passing distance between own ship and a target by indicating an exact danger area between own ship and the target ship. The apparatus has a collision point calculator which calculates a possible collision point of each of the vertexes of a polygonal safe passing region set around own ship, and the target ship, from a relative position of the target ship, a velocity vector of the target ship and a velocity of own ship. The apparatus has an own-ship-mapping-position calculator which calculates a position at which own ship would be located when each of the vertexes places on the collision point, and defines the position as a own-ship-mapping-position. The apparatus further has a danger area calculator which determines lines joining own-ship-mapping-positions corresponding to the collision points with each other to define a danger area.Type: GrantFiled: March 3, 1995Date of Patent: May 7, 1996Assignee: Tokimec Inc.Inventors: Tadashige Hakoyama, Yoshio Kato, Satoki Maeda, Hideo Yamaguchi, Osamu Yagi

Patent number: 5387931Abstract: A carrier level balancing circuit in which a color aliasing signal occurring when a cameraman takes a picture of an object of an achromatic (black and white) color can be canceled completely. In a carrier level balancing circuit for a color camera formed of a CCD solid state image pickup device of an all pixel separately read out system, two-channel color signals output from the CCD solid state image pickup device are multiplied with independent balance coefficients at every line by multipliers while the balance coefficients are switched in a dot-sequential fashion. Also, values of these balance coefficients are set by a coefficient setting circuit in response to color temperature information. Thus, the carrier levels can be balanced over a range of color temperatures.Type: GrantFiled: April 22, 1993Date of Patent: February 7, 1995Assignee: Sony CorporationInventors: Osamu Yagi, Toru Wakagi
