Title: Emballage dote d'un couvercle a deux pellicules comprenant une pellicule impermeable aux gaz et une pellicule permeable aux gaz et decollable
Inventor: KOCHER PATRICK N
IPC: B32B27/08
Filed: 1997-11-24
Granted: 2006-10-03
Abstract: On décrit un emballage à deux pellicules et un procédé de fabrication de ce dernier qui combine la simplicité de fabrication d'un emballage à couvercle unique pelable et la caractéristique de pelabilité d'un emballage comportant des couvercles perméable et imperméable séparés. On utilise pour cela un élément (12) de support et un couvercle (24) comprenant une pellicule (26) perméable aux gaz et une pellicule (28) sensiblement imperméable aux gaz. Une première thermosoudure (30) lie la pellicule perméable aux gaz à l'élément de support et une deuxième thermosoudure (32) lie la pellicule imperméable aux gaz à la pellicule perméable aux gaz. Les première et deuxième thermosoudures ont chacune une résistance d'adhésion qui est supérieure à la résistance cohésive intra-pelliculaire de la pellicule perméable aux gaz de sorte que le couvercle se décolle de préférence à l'intérieur de la pellicule perméable aux gaz lorsqu'on l'arrache, ceci ayant pour effet de laisser une partie de la pellicule perméable aux gaz collée sur l'élément de support.

Abstract: L'invention a trait à un appareil et à un procédé de production d'articles en bois consolidé ou reconstitué et ce, à partir d'une charge d'éléments en bois et d'un liant pressés sous injection de vapeur, afin de consolider et de lier ladite charge, ce qui permet de constituer un matte dans lequel les éléments en bois sont liés les uns aux autres et donnent l'article en bois. La charge est comprimée en matte à l'aide d'au moins un organe de pressage sous forme de table mobile chauffée. Le procédé et l'appareil correspondant se caractérisent par le fait que la pression appliquée à la charge ou au matte par pressage sous injection de vapeur est indépendante de la force de compression appliquée à la charge ou au matte à l'aide de l'organe de pressage. Cette invention convient tout particulièrement à la constitution de poutres de section transversale relativement importante, dépassant par exemple 30 mm, 40 mm de préférence.

Title: Gps multipath detection method and system
Inventor: SHEIKH SUNEEL I
IPC: G01S1/00
Filed: 1997-11-20
Granted: 2005-05-10
Abstract: A multipath detection method for use in a GPS position determination system includes providing a code pseudorange measurement representative of a range of an antenna to a space vehicle and a carrier phase pseudorange measurement representative of the range of the antenna to the space vehicle. A code-carrier measurement difference is then generated between the code pseudorange measurement and the carrier phase pseudorange measurement. This code-carrier measurement difference is examined to determine if a multipath component is present. If the difference indicates that multipath is likely to be present, use of such measurements in computing position solutions, such as attitude solutions, is avoided. A multipath detection system for carrying out the method is also described.

Abstract: A system determines that a frame relay connection exists between an interface on a first interface device and an interface on a second interface device, for example by comparing addresses resident in routing tables of the interface devices. The system then queries each of the first and second interface devices, to determine the amount of traffic that is communicated by each channel of each of the two interfaces. This data is then correlated to determine the relative amount of data by each channel on each of the two interfaces, and the pair of channels having the best correlation are determined to represent an actual connection.

Abstract: A composition for saturation of preformed, previously cured foam substrates having an at least partially open cell configuration, includes a polymer binder in which microspheres containing a phase change material are dispersed. Preferred phase change materials include paraffinic hydrocarbons. The microspheres may be microencapsulated. A  preferred cured foam substrate is a skived polyurethane or polyether foam of from 20 to 1,000 mils in thickness, preferably 20 to 200 mils in thickness, having up to 6 ounces per square yard or more of encapsulated phase change material embedded in a polymer binder. One method of applying the binder with dispersed encapsulated phase change materials is by applying a binder/microsphere dispersion to the upper surface of a previously cured foam sheet, then drawing a vacuum from the underside of the cured foam sheet to permeate from 20 % to 100 % of the cured foam sheet with the binder/microsphere dispersion. The resulting product is then cured. An alternative method of applying the binder with embedded encapsulated phase change materials using knife over roll technique to an exposed surface of the skived foam is disclosed in which the most preferred viscosity of the uncured polymer binder is from 7,000 to 9,000 centipoise.

Title: Method for packet transmission using an arq protocol on transmission channels in a digital transmission system
Inventor: PLECHINGER JORG
IPC: H03M13/45
Filed: 1998-07-29
Granted: 2005-03-15
Abstract: In a method for packet transmission using an ARQ protocol on transmission channels in a digital transmission system, for channel coding, turbo coding is carried out in a turbo coder at the transmitter end and turbo decoding is carried out in a turbo decoder at the receiver end using soft-decision output signals, with a return channel being provided, using which the receiver requests the information from faulty packets once again. An RCPTC is used as the turbo code. When the information in a faulty packet is transmitted once again, at least a portion of the information suppressed by the puncturing of the RCPTC in the previous transmission is transmitted. This additional information is inserted into the already existing information at the receiver end, and this completed information is decoded once again. When the repeat transmission is made, the only bits which are transmitted are those which are additionally available at the next lower coding rate, since they are not punctured. The method is repeated until the packet is decoded without any errors or all the coded information in a packet is transmitted.

Abstract: Systems and methods for registering hemispheric images obtained using a fisheye lens for panoramic viewing, relating to spatial alignment and colour balancing of complement half-side images derived from the hemispheric images. The systems and methods for spatial alignment determine the displacement of the digitized recorded images using a single translation and rotation model of distortion, which further evaluates the centre of projection, and the extent of translation and rotation. The system and method for colour balancing iteratively increase (or decrease) the values of pixels near the edge (discontinuity) between the two half-sides of an image, each time taking into consideration the average difference of pixel colour across a smaller strip of the edge near the pixel. This invention removes the colour differential but does not remove any detail underlying the features of the image.
