Abstract: Selon cette invention, un système de guide de programmes multiple et interactif (IPG) fournit différents programmes de télévision et IPG à plusieurs utilisateurs différents, respectivement. Un seul décodeur est capable d'effectuer la programmation et l'ordonnancement des données à destination de plusieurs postes de télévision. Chacun des différents IPG partage une base de données commune. Ainsi, un premier IPG visualisé par un premier utilisateur peut afficher des données ajoutées ou modifiées via un deuxième IPG par un deuxième utilisateur du système. En outre, les données ajoutées ou modifiées par le deuxième utilisateur peuvent influencer les droits de visionnement du premier utilisateur. De même, toutes les demandes concurrentes ou en conflit en rapport avec des ressources limitées telles que les enregistrements par magnétoscope ordonnancés seront soumises à l'attention des utilisateurs et affichés par le système.

Abstract: L'invention concerne un mélange de gaz optimum préparé à partir du groupe de fluides de composés, utilisé dans un système miniature de réfrigération de gaz mélangés. Le mélange de gaz a des composés appropriés, dans des concentrations appropriées, afin d'optimiser la puissance de réfrigération et la capacité de transfert de chaleur, et de minimiser l'obturation de l'élément d'expansion Joule-Thomson. Le mélange de gaz est pressurisé par un compresseur à une pression inférieure à 750 psia, et de préférence, inférieure à 420 psia, pour des raisons de sécurité, et alimenté par un échangeur de chaleur. La sortie à haute pression de l'échangeur de chaleur est reliée à l'élément d'expansion Joule-Thomson, où le gaz à haute pression est dilaté de manière isenthalpique à une température basse inférieure au moins à 183K. Ce gaz à basse température refroidit un élément de transfert de chaleur fixé sur l'extrémité distale de la sonde, pour refroidir un objet externe. Le gaz de retour s'écoule en retour à travers l'échangeur de chaleur pour refroidir une première fois le mélange de gaz à haute pression entrant.

Title: Method and apparatus for transmitting the sync channel message in a multi-carrier communication system
Inventor: JOU YU-CHEUN
IPC: H04L29/02
Filed: 2000-04-21
Granted: 2008-07-15
Abstract: A method and apparatus for transmitting broadcast information in a multi- carrier communication system. The Sync Channel of the multi-carrier system is transmitted a 1.25 MHz channel bandwidth (i.e., over a single carrier), and to specify the preferred channels for the Sync Channel transmission instead of the preferred channels for the entire multi-carrier system. The Sync Channel Message will carry the additional information to indicating the center frequency of a multi-carrier system within a reserved set of frequency bands and indicating the frequency of a single carrier system in the reserved set of frequency bands. Considering the A block of the PCS band again, the preferred channels for Sync Channel transmission can be selected as channels 75, 150 and 225. This selection ensures that one of the preferred channels will always be used by any multi-carrier system regardless of the location of its center channel.

Patent CA-2372833-C (CA)
Inventor: TROYER DIANE
IPC: H04N9/31
Filed: 1999-04-30
Granted: 2013-01-15
Abstract: A laser projection system wherein speckle is suppressed through beam-path displacement, by deflecting the beam during projection, thereby avoiding both absorption and diffusion of the beam while preserving pseudocollimation (noncrossing rays). Path displacement is achieved by scanning the beam on liquid crystal light valves (LCLV's) (30), which also provide enhancements -in energy efficiency, brightness, contrast, beam uniformity (by suppressing both laser-mode ripple and artifacts). Preferably deflection is performed by a mirror (20) mounted on a galvanometer or motor (21) for oscillation; images are written incrementally on successive portions of an LCLV control stage while the laser "reading beam" is synchronized on an output stage. Beam splitter analyzer cubes (25) are preferred over polarizing sheets.
