Title: Method of seaming and expanding amorphous patterns
Inventor: MCGUIRE KENNETH STEPHEN
IPC: G06T11/40
Filed: 2000-04-06
Abstract: The present invention provides a method for creating amorphous patterns based on a constrained Voronoi tesselation of 2-space that can be tiled. There are three basic steps required to generate a constrained Voronoi tesselation of 2-space: 1) nucleation point placement; 2) Delauney triangulation of the nucleation points; and 3) polygon extraction from the Delauney triangulated space. The tiling feature is accomplished by modifying only the nucleation point poriton of the algorithm. The method of the present invention, for creating an amorphous two-dimensional pattern of interlocking two-dimensional geometrical shapes having at least two opposing edges which can be tiled together, comprises the steps of: (a) specifying the width x max of the pattern measured in direction x between the opposing edges; (b) adding a computational border region of width B to the pattern along one of the edges located at the x distance x max; (c) computationally generating (x, y) coordinates of a nucleation point having x coordinates between 0 and x max; (d) selecting nucleation points having x coordinates between 0 and B and copying them into the computational border region by adding x max to their x coordinate value; (e) comparing both the computationally generated nucleation point and the corresponding copied nucleation point in the computational border against all previously generated nucleation points; and (f) repeating steps (c) through (e) until the desired number of nucleation points has been generated.      To complete the pattern formation process, the additional steps of: (g) performing a Delaunay triangulation on the nucleation points; and (h) performing a Voronoi tessellation on the nucleation points to form two-dimensional geometrical shapes are included. Patterns having two pairs of opposing edges which may be tiled together may be generated by providing computional borders in two mutually orthogonal coordinate directions.

Title: Common packet channel
Inventor: PARSA KOUROSH
IPC: H04B1/707
Filed: 2000-03-21
Abstract: An improvement to a code-division-multiple-access (CDMA) system employing spread-spectrum modulation, with the CDMA system having a base station (BS) and a plurality of remote stations. The base station has a BS-spread-spectrum transmitter and a BS-spread-spectrum receiver. A remote station has an RS-spread-spectrum transmitter and an RS-spread-spectrum receiver. The BS transmitter transmits a broadcast common-synchronization channel, which includes a frame-timing signal. The broadcast common-synchronization channel has a common chip-sequence signal, which is common to the plurality of remote stations. In response to the RS-spread-spectrum receiver receiving the broadcast common-synchronization channel, and determining frame timing from the frame-timing signal, an RS-spread-spectrum transmitter transmits an access-burst signal, which RS-power-control signals transmitted in time, at increasing power levels. The BS-spread-spectrum transmitter, responsive to the BS-spread-spectrum receiver receiving the access-burst signal, and detecting an RS-preamble signal, transmits an acknowledgment signal. In response to the first RS-spread-spectrum receiver receiving the acknowledgment signal, the first RS-spread-spectrum transmitter transmits a spread-spectrum signal having data. The BS-spread-spectrum transmitter transmits either data or power-control information to RS-spread-spectrum receiver.

Title: Detection and quantification of micro-organisms using amplification and restriction enzyme analysis
Inventor: VAN HAERINGEN WILLEM ANNE
IPC: C12Q1/683
Filed: 2000-03-01
Abstract: In livestock a number of pathological conditions and/or syndromes have been noticed that do not seem to be attributable to e.g. an infection with a single micro-organism. These syndromes however do seem to have an effect on the equilibrium which normally exists within the different bacteria constituting the bacterial flora. A number of these syndromes are referred to as dysbacteriosis and bacterial overgrowth. To enable at least in part the evaluation of the "general" health of the livestock the invention provides means and methods for analysing the composition of a microbiological flora. In one aspect a method of the invention comprises providing a sample of said flora, selectively amplifying nucleic acid present in said sample, subjecting the amplificate to restriction digestion and analysing the resulting pattern of restriction fragments.

Abstract: Pulp fibers can be treated with adsorbable chemicals with a minimal amount o f unadsorbed chemical additives present later in the papermaking process water . A method for adding an adsorbable chemical to pulp includes mixing pulp fibe rs that have never been dried with water to form a fiber slurry. An adsorbable chemical additive is added to the fiber slurry. The fiber slurry having the adsorbable chemical additive is transported to a web-forming apparatus where  a wet fibrous web is formed. The wet fibrous web may be dried to a predetermin ed consistency thereby forming a dried fibrous web having from between about 10  to about 100 percent retention of the adsorbable chemical additive. The drie d fibrous web is transported to a paper machine where the dried fibrous web is  mixed with water to form a wet slurry. In other embodiments, the fiber slurr y can be processed to provide crumb fibers or wet lap fibers. The wet slurry containing the fibers having the adsorbable chemical additive adhered theret o is transported through the paper machine to form a finished paper or tissue product having enhanced quality due to the retention of the adsorbable chemical additive on the pulp fibers.
