Title: Handling hierarchically structured data
Inventor: NAGAI TSUYOSHI
IPC: G06F17/30
Filed: 1996-02-02
Abstract: Identifiers are added, S1, to data pieces that are elements of hierarchically structured data. The method determines, S2, whether or not there are two or more data pieces with the same identifier in a hierarchical data sequence composed of a second data piece placed below a first data piece, determines, S3, that an infinite hierarchical structure takes place when there are two or more data pieces with the same identifier if the second data piece is placed below the first data piece, and determines, S4, that an infinite hierarchical structure does not take place when there are not two or more data pieces with the same identifier, even if the second data piece is placed below the first data piece. Corresponding to the determined result, data placement that results in an occurrence of an infinite hierarchical structure, and which otherwise would involve repeated retrieval of the same data, can be prevented.

Title: Embroidery machine control
Inventor: KAYMER ANDREW BENNET
IPC: D05B19/08
Filed: 1996-09-09
Abstract: To generate stitch data relating to a lettering design, the letters of the design are created 26 in the memory of the computer so that the letters of each pair of adjacent letters are spaced apart by a standard gap 27. The distance between the closest node points of the first and second letters is then calculated 30 and this distance is compared with a parameter which is proportional to the standard gap. The spacing between the first and second letters is then reduced if said distance is greater than said parameters. These steps are then repeated 31 for each subsequent adjacent pair of letters in the design. The stitch data for the letters of the design so spaced is then written 33 onto a storage medium.

Title: Method and Apparatus for Ear Irrigation
Inventor: SMITH LESLIE RIPPON
IPC: A61M3/02
Filed: 1997-10-30
Abstract: A method for the irrigation and cleansing of the ear passage relies on a pulsing fluid pump 100, equipped with a water tank 40, and driven by an electric motor 80. A valve 35 controls the supply of water to the pump and hence the pump back pressure such that the pump gives variable frequency pulses as well as high pressure pulses at low frequency and low pressure pulses at high frequency. A flexible tube 101 delivers the fluid pulses to the ear via a hollow plastic probe 24. The probe, which is equipped with a handle 250, has apertures such that the direction of the pulse is substantially perpendicular to the length of the probe.

Title: Anisotropic texture mapping using silhouette/footprint analysis in a computer image generation system
Inventor: LEE HARRY CHARLES
IPC: G06T15/04
Filed: 1998-11-20
Abstract: Anisotropically mapping of texture information to each pixel required for display of each of plural polygons forming each scene on a CIG display in a computational efficient manner, uses the footprint of each transformed pixel silhouette, as mapped from image space into the texture array, to determine an anisotropic texture space area having both a related length and a related width, in which complete texels and texels fractions are covered by that pixel footprint. A set of unnormalized line equations characterizing a particular pixel footprint is used to determine whether each texel or subtexel in the vicinity of that pixel footprint is either enclosed or avoided by (i.e. inside or outside of) that projected pixel footprint.
