Title: Collision avoidance navigation apparatus
Inventor: HAKOYAMA TADASHIGE
IPC: G01S13/937
Filed: 1995-03-06
Abstract: A navigation supporting display apparatus has a collision point calculator (2) which calculates a possible collision point of each of the vertices 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. An own-ship-mapping-position calculator (3) calculates a position at which own ship would be located when each of the vertices is placed on the collision point, and defines the position as an own-ship-mapping-position. A danger area calculator (4) determines lines joining own-ship-mapping-positions corresponding to the collision points with each other to define a danger area. The relation between connected own-ship-mapping-positions and the own-ship-mapping-positions are output to a display device (5) which displays the area defined by the lines joining own-ship-mapping-positions as a danger area together with the position and the vector of own ship and the position of the target ship. <IMAGE>

Title: Method for manufacturing a fluorescent lamp
Inventor: OGA TOSHIYOSHI
IPC: C03B23/207
Filed: 1999-03-09
Abstract: In a method for manufacturing a fluorescent lamp, four dual tubes (21a, 21 b, 22a and 22b) that are previously manufactured are held at a distance in such a manner that the dual tubes can move horizontally. Four portions for connection are simultaneously heated, and two of the dual tubes (21a and 21 b) are simultaneously moved horizontally (31) to form bridges (3b) to provide two tube assemblies (23a and 23b). Furthermore, annealing after bridge connection and the connection of tube assemblies (23a and 23b) with a further bridge are performed simultaneously. Thus, a compact fluorescent lamp comprising eight glass tubes that are connected with bridges to form continuous discharge paths can be obtained. According to the manufacturing method, bridge connection can be performed in a small space and with high productivity, and a fluorescent lamp having a good quality with minor variations in the quality of the bridge portions can be provided. Alternatively, the bridge between the two dual tubes (22a and 22b) can be formed before the bridges are formed between the dual tubes (22a and 22b) and the dual tubes (21a and 22a, and 21b and 22b).

Title: Synchronization of video and audio signals
Inventor: WILSON JOHN MICHAEL
IPC: H04N7/52
Filed: 1999-03-12
Abstract: In order to synchronise video and audio signals, a video test signal and an audio test signal are generated at the transmitting end of a transmission link, and transmitted over the link. The video test signal has first and second active picture periods of contrasting states. The audio test signal has first and second periods of contrasting states. As generated, the video and audio test signals have a predetermined timing relationship - for example, their changes of respective states may be coincident in time. At the receiving end of the link, the video and audio test signals as received are detected, and any difference of timing between the video and audio test signals is derived from their changes of respective states, measured and displayed, including an indication of whether the video signal arrived before the audio signal or vice-versa. Additionally or alternatively, such a measurement signal can be used in a control loop to compensate for the delay and automatically re-synchronise the audio and video signals. The system is particularly suitable for transmission of video and audio over separate paths of a link - e.g. respectively over satellite and terrestrial paths.
