Abstract: A picture drawing or method used in a graphics computer, a special effect device or a video game machine. For generating data required for picture drawing by pre-processing by a pre--processor 32 based on a drawing command for drawing a picture model defined by the combination of unit figures, and generating pixel data on the unit figure basis by texture mapping based on the generated data for drawing a picture on a frame buffer 18, the texture data required by a drawing engine 33 is transferred in the pre-processing stage from a texture area on the frame buffer 18 to a texture cache 33F, and the pre-processor 32 and the drawing engine 33 are operated in pipelining. This enables texture mapping or MIP mapping without halting the picture drawing means, while reducing the number of times of texture memory accessing and the accessing time for raising the overall picture drawing speed.

Abstract: Verification patterns (19) are associated with barcodes (1) to provide rapid , visual confirmation that a barcode is printed within acceptable tolerances. A master of a barcode to be produced includes at least one verification patter n (19) including a wedge (21) formed by an unprinted area or areas bounded by a printed area or areas. During reproduction, an anticipated degree of ink- spread will cause a predetermined degree of shortening of the wedge, while abnormal degrees of shortening are an indication of press and/or pre-press errors and/or an inappropriately specified master. With a suitably dimension ed wedge, compliance with bar and space width tolerances can be assessed. Two types of verification patterns (19, 19A) may be used in conjunction with a single bar code to enable detection of different types of errors.

Granted: 2002-07-16
Abstract: A new data communication system is described which enables data transmission  over existing telephone lines at rates higher than possible with existing methods, including conventional modems. By using a novel asymmetric configuration of the two communicator endpoints, the currently-accepted maximum theoretical limits on the data rate are no longer applicable. One endpoint is connected directly to a digital telephone network, whereas the other endpoint uses a conventional telephone connection. This reduces the transmission problem to compensation for a single telephone line interface a nd a single analog local loop. Means of providing this compensation and the required clock synchronization were also created, enabling a practical implementation of the system. The new system can achieve rates up to 64,000 bits-per-second and has broad utility in several active areas including wide - band audio transmission, video transmission, networking, facsimile transmission, and remote computer access.

Title: Vibration isolation insert for aircraft floor panels and the like
Inventor: HAIN HARRY L
IPC: F16F1/373
Filed: 1997-09-04
Granted: 2005-08-02
Abstract: An insert (20) used to connect aircraft floor panels (11), and the like, to supporting structure (13) includes features which function to isolate the supported panel (11) from vibrations in the supporting structure (13). The isolation of the panels (11) leads to reductions in SIL (Speech Interference Level) noise within aircraft cabins. The insert (20) consists of internal and external rigid components separated by a contoured elastomeric component (32). The elastomeric component (32) is preloaded when installed via a fastener (15) extending through the inner rigid component (42, 42') and attaching to the supporting structure (13). The outer (22, 22') and inner (42, 42') rigid components are sized such that the inner rigid component (42, 42') will not pass through the outer rigid component (22, 22'), thus providing a safetied installation of the panel (11). The elastomeric component (32) extends below the bottom of the outer rigid component (22, 22') and provides soft snubbing against the supporting structure during loading of the panels (11). This allows some level of isolation while restricting motion of the panels (11).
