Abstract: An integrated security and communications system combines a security system to either or both of a telephone system interface and a data interface. Users have access to voice-mail or other PBX-type telephone functions, many or all of which can be accessed not only at telephone sets, but also at keypads of the security system. Data functions such as electronic mail and possible partial or full World Wide Web access may also be provided at the keypads, as well as at connected personal computers or computer terminals. The system keypads may be enhanced to better accommodate some of the added functions. A central communications station could be used to maintain secure, shared private key encrypted communications with each premises system, using a redirector arrangement or relay to allow each premises system to communicate securely with a central monitoring station and with other systems.  The secure communications system could be used without a security system to allow secure computer-to-computer communications.

Abstract: The invention relates to the use of ratios of Raman peak intensities to predict the properties of a solution or a solid such as pulp that is processed with the solution. The intensity of the Raman shifted light is used to create Raman peak intensity ratios. These Raman intensities are related to the concentration of species dissolved in the liquid. The Raman spectra are baseline corrected and the scattering from a water reference is subtracted before extraction of intensities for Raman peak intensity ratios. The Raman scattering intensities provide a good measure of the concentration of small, oxygenated molecules. The potential of an oxidative reductive process is conveniently determined using Raman peak intensity ratios. The method may also be used to determine a property related to the relative size, degree of polymerization, branching or network formation of complexing or polymerized species, or to measure large molecules such as hemicellulose, extractives and pectic substances.

Title: System and process for distribution of information on a communication network
Inventor: RITTMASTER TED R
IPC: G06Q30/00
Filed: 2001-03-20
Abstract: A communications system includes a plurality of recipient processors located at remote locations with respect to each other and connected to an information provider processor (12) over a communication network. The provider (12) and recipient (124) processors may communicate through the Internet (18). The provider processor (12) can provide information from any suitable source over a communication network. However, access to the information by the recipient processors is controlled based on the geographic location or region of the recipient processors (124). Each recipient processor is operably associated with a positioning system, such as a global positioning system GPS (130, 126) to provide its location. The location information is used to determine whether or not the processor requesting the information is within a restricted or non-restricted region. This determination may be made by comparing the geographic information of the recipient processor with a list of non-restricted or restricted geographic locations or regions.

Title: Multi-band spectral audio encoding
Inventor: SRINIVASAN VENUGOPAL
IPC: G10L19/02
Filed: 2001-04-03
Abstract: An encoder includes a sampler that samples an audio signal and that generates from the samples a plurality of short blocks of sampled audio. Each of the short blocks has a duration less than a minimum audibly perceivable signal delay. A processor combines the plurality of short blocks into a long block.  The long block is transformed into a frequency domain signal having a plurality of independently modulatable frequency indices. The frequency difference between adjacent indices is determined by the minimum duration and the sampling rate of the sampler. A neighborhood of frequency indices is selected so that the frequency difference between a lowest index and a highest index within the neighborhood is less than a predetermined value. Two or more of the indices are modulated in the neighborhood so as to make a selected one of the indices an extremum while keeping the total energy of the neighborhood constant. A plurality of frequency bands are so coded. A decoder decides that a bit or bits have been received if, in a majority of the frequency bands, the decoder detects a modulated index.

Abstract: A process for producing tissue webs is disclosed. More particularly, the present invention is directed to an improved process for drying webs.  According to the present invention, a formed web still containing a substantial amount of moisture is passed through a nip formed between a press roll (43) and a heated drum (46). When passed through the nip, the web is placed on a porous fabric (40). The web is then carried through the nip for a period of time and subjected to temperatures and pressures sufficient to create a steam front which travels through the web and expels a significant amount of moisture from the web through the porous fabric.

Abstract: The present invention provides a lottery type game system, method and ticket, wherein the winning of a game is determined by the assignment of game images to a predetermined number of consecutive positions along a linear array. The value of the prize is determined by the precise position along the linear array at which this predetermined number of game images are assigned. The assignment of the position of a game image can be established by: a) matching a game image associated with a particular gaming piece with an identical image located at a predetermined position along the linear array; or b) receiving a game piece upon which both the game image and the assigned position of the game image along the array is indicated.

Abstract: L'invention concerne un procédé d'alimentation axial du matériau à séparer dans un séparateur dynamique de milieu dense (1). Le procédé est fondé sur le principe consistant à conférer au matériau et au fluide, dans lequel il est dispersé, une composante de vitesse de rotation par rapport à l'axe du séparateur (1) afin de faciliter l'introduction du matériau et du fluide dans ce dernier (1); de cette façon, les particules de matériau ont un mouvement correspondant à celui de la circulation de milieu dense dans le séparateur, ce qui empêche une dispersion incontrôlée des particules à l'intérieur de ce dernier. L'invention concerne également un dispositif d'alimentation (2) servant à mettre en oeuvre le procédé décrit ci-dessus.

Abstract: L'invention concerne un indicateur de défauts internes pour dispositif électrique, qui se déclenche lors d'une augmentation soudaine de pression se produisant par exemple lorsqu'un défaut d'isolement produit un arc électrique. La chaleur libérée dans l'arc est transférée au volume environnant, entraînant une surchauffe locale, une vaporisation et une décomposition de la matière isolante. La saute de pression résultante déplace un diaphragme. Ce déplacement du diaphragme libère un poussoir à ressort d'un cylindre qui s'étend à travers le corps du dispositif électrique. Avant activation, le poussoir est maintenu dans une position <= armée >= parune goupille de retenue. Lors du déclenchement, le poussoir est poussé par le ressort de manière à dépasser du corps, afin de fournir un signal visuel du défaut interne. Une soupape de sécurité peut être intégrée à l'indicateur de défauts internes.

Abstract: L'invention concerne un procédé d'identification de peptides qui se lient avec un récepteur cellulaire (en surface ou intracellulaire), du type récepteur nucléaire, par criblage de bibliothèque de peptides combinatoire se présentant sous la forme de cellules qui co-expriment chacune un peptide de la bibliothèque et le récepteur, avec utilisation de système de production de signaux notifiant la liaison. A cet égard, le dosage en "deux hybrides" présente un intérêt particulier. Le criblage peut être réalisé en présence d'un ligand, en particulier un ligand exogène. S'il s'applique à une pluralité de conformations différentes de récepteurs, ce criblage de bibliothèque permet aussi d'identifier les peptides spécifiques à telle ou telle conformation pour le récepteur considéré, offrant ainsi la possibilité d'une utilisation dans un panel de peptides pour relever les "empreintes digitales" peptidiques de composés d'intérêt dont on cherche à déterminer le potentiel d'interaction avec le récepteur en présence de chacun des peptides du panel. Il est possible de comparer les empreintes en question avec celles de composés de référence pour lesquels la médiation d'activités biologiques connues est assurée par le récepteur concerné.
