Abstract: Dispositif (10) de chauffage par induction conçu pour réguler la distribution thermique dans un matériau électroconducteur, ou un suscepteur (60), lorsqu'il est chauffé par des courants de Foucault. Un matériau non électroconducteur peut être chauffé de manière régulée en plaçant le matériau près du suscepteur. Une énergie variable est fournie par ou un plusieurs circuit(s) (30) de commutation à de multiples sections d'une bobine d'induction (40) enroulées sur la longueur du suscepteur, à partir d'une source d'énergie. Les sections de la bobine peuvent être superposées (80), enroulées en sens inverse (121) entre deux sections de la bobine adjacentes ou alimentées en cascade, afin d'obtenir la distribution thermique voulue dans le suscepteur. Un circuit (50) de commande est utilisé pour réguler l'énergie fournie à chaque section de la bobine et la sortie de la source d'énergie. Si un matériau non électroconducteur est placé près du suscepteur, ledit matériau peut être chauffé de manière régulée.

Abstract: A method for controlling downlink power in a time-division multiplex wireless system may provide different downlink transmit signal powers to different time-division multiplex channels of a single carrier. A base station receives a measured signal parameter data for a downlink transmit signal of a time-division multiplex channel. The base station determines an initial adjustment for the downlink transmit signal power of the time division multiplex channel if the measured signal parameter data differs from a target signal parameter data. The base station determines a revised adjustment for the downlink transmit power of the time division multiplex channel based on the initial adjustment and at least one adjustment range as appropriate to achieve synchronization of the demodulation of the downlink transmit signal.

Abstract: An elastomeric mask is provided that allows deposition of a variety of materials through mask openings. The mask seals effectively against substrate surfaces, allowing simple deposition from fluid phase, gas phase, and the like or removal of material using gaseous or liquid etchants. The mask then can be simply peeled from the surface of the substrate leaving the patterned material behind. Multi-layered mask techniques are described in which openings in an upper mask allow selected openings of a lower mask to remain unshielded, while other openings of the lower mask are shielded. A first deposition step, followed by re-orientation of the upper mask to expose a different set of lower mask openings, allows selective deposition of different materials in different openings of the lower mask. Pixelated organic electroluminescent devices are provided via the described technique.

Abstract: La présente invention concerne un allume-gaz de ménage (1) avec dispositif anti-allumage. La fonction anti-allumage est réalisée au moyen d'un mécanisme à came (60) avec moyeu (61). Ce moyeu comporte trois parties saillantes internes : le levier de came (80), le levier de libération du combustible (70) et le ressort de rappel (90). Lorsqu'il est enfoncé, le bouton de sécurité (120) intégré au levier de came libère le levier de came (80) de l'ergot de butée (110) de la détente (100). La détente (100) comporte également une rampe inclinée (111) située sous l'ergot de butée (110) dans lequel s'engage le levier de came (80) lorsque le bouton de sécurité (120) est enfoncé et que l'on appuie sur la détente (100). Une fois la détente (100) enfoncée, le levier de came (80) se déplace sur la rampe inclinée (111) et tait tourner le mécanisme de came (60). Lorsque le mécanisme de came (60) a tourné, le levier de libération de combustible (70) ouvre la soupape (31) du même nom, ce qui permet au combustible d'atteindre la tige d'allumage (16). Dès que le bouton de sécurité est relâché, le ressort de rappel (90) ramène le mécanisme de came à force sur la position initiale de blocage.

Abstract: A fabric having at least one hydraulically napped surface comprised of tangled fibers is disclosed. Because the fiber tangles are created from intact, undamaged fibers, fabric strength is not adversely affected by treatment. In addition, laundering enhances entanglement and the aesthetic qualities attributed to this fabric property: surface texture (hand), resistance to pilling, drapeability, and the like. These subjective characteristics have been quantified using values from the Kawabata Evaluation System.  A process for creating such fabrics has also been disclosed. The fabric passes through one or two treatment zone in which high pressure fluids (e.g., water) are directed at the fabric surface as the fabric moves away from a support member. In the case of dual treatemnt zones, a substantially lower pressure is used in the second treatment zone.

Abstract: A telecommunications terminal that intelligently determines whether to notify the user of an incoming message is disclosed. In the illustrative embodiments, the terminal has a processor that makes this determination based on one or more of the following: the time and date (i. e., the "calendrical time"), environmental parameters (e.g., temperature, ambient luminosity, etc.), the user's physiological parameters (e.g., blood pressure, heart rate, etc.), the location of the user, the proximity of other wireless terminals in the vicinity, the semantic content of the message, the identity of the sender of the message, and whether the user is currently receiving another message. For example, a user might not want to be notified of an incoming message that arrives between 10:00 P.M. and 6:00 A.M. unless the user is awake or the sender of the message is a family member.
