Title: Method and system for effective switching between set-top box services
Inventor: COX DAVID
IPC: H04N7/16
Filed: 2002-11-08
Abstract: The invention relates generally to convergent multimedia systems, and more specifically, to effective switching between different services in a television set-top box (STB) environment. Two services which are often supported by STBs are regular television, and Internet over television (IoTV) services. Most STBs only have the resources to support one service at a time - thus, to toggle between a television program and an email service, the user must close the television program window and launch a new software application for the email service. Opening and closing software applications is a slow process, and the state of IoTV applications is lost when they are closed. The invention provides a method of operation for a STB which responds to toggle commands by switching the users display between the television and IoTV services, but keeping the IoTV service operable and its state current even when the user is viewing the television service.

Abstract: La présente invention concerne des composés modificateurs de la cystéine comprenant de l'arginine utiles dans l'analyse de protéines par spectrométrie de masse à désorption-ionization par impact laser assistée par matrice (MALDI-MS). Ces composés appelés réactifs activateurs d'ionisation à code isotopique (RAICI) peuvent produire une activation d'ionisation dans l'analyse MALDI-MS, une quantification relative, et des contraintes additionnelles à la recherche dans les bases de données supplémentaire simultanément sans manipulation additionnelle d'échantillons. Plus spécifiquement, les RAICI accroissent l'efficacité de l'ionisation de peptides contenant de la cystéine par la fixation d'un groupe fonctionnel guanidino. Les RAICI accroissent également l'hydrophilie globale de ces peptides en raison de la nature hydrophile des RAICI et accroissent ainsi le pourcentage de récupération de ces peptides en cours de manipulation et de traitement d'échantillons comme par exemple dans la digestion en gel ou la chromatographie liquide. Enfin, une association de RAICI légers et lourds fournit un moyen précis d'obtention d'une quantification relative de protéines par analyse MALDI-MS et de contraintes additionnelles à la recherche dans les bases de données (nombre de résidus de cystéine dans chaque pic de peptide individuel) afin d'augmenter la fiabilité de l'identification de protéines par la cartographie de masse de peptides.

Inventor: MILLER WANDA J
IPC: G05B13/02
Filed: 2002-12-19
Abstract: A pull-down control algorithm for an HVAC refrigeration system (100) is provided. The control algorithm utilizes a fuzzy logic methodology to automatically adjust a flow of refrigerant in the system (100) during a pull-down to maintain a desired pull-down rate. The desired pull-down rate is decreased proportionately as the temperature of the fluid being pulled down approaches a desired operating setpoint to avoid or minimize any overshoot of the operating setpoint. The desired pull-down rate is obtained by adjusting a rate sensitivity factor used in the control algorithm. When the temperature of the fluid being pulled down is above a predetermined value from the operating setpoint, the control algorithm uses a fuzzy logic methodology to determine a rate sensitivity that results in the desired pull-down rate that approaches the operating setpoint without overshoot.
