Patent CA-2382764-A1 (CA)
Inventor: YEOM JAE-HEUNG
IPC: H04W28/00
Filed: 2001-06-23
Abstract: L'invention concerne un procédé et un dispositif permettant de transmettre/recevoir des informations de commande de débit de données (DRC) dans un système de télécommunication mobile en vue d'une transmission de données par paquets. Pour déterminer un débit de données sur la liaison aval dans un système de télécommunication mobile tel qu'un système HDR, les informations DRC sont transmises sur la liaison inverse uniquement au moment de programmer les données utilisateur. Un réseau d'accès (AN) transmet un bit d'indicateur de demande DRC (DRI) ou un terminal d'accès (AT) détecte les préambules de tous les utilisateurs, voire son propre préambule, afin de commander la transmission des informations DRC. Conjointement avec la commande de transmission des informations DRC, certains AT sont commandés de façon à transmettre des voies pilotes et des voies RRI à différents points temporels à partir d'autres AT. Par conséquent, la charge d'interférence sur la liaison inverse est réduite, d'où une augmentation de la capacité du système au niveau de la liaison inverse.
Patent CA-2383066-A1 (CA)
Inventor: CHEN BO SU
IPC: G01R33/02
Filed: 1999-06-29
Abstract: A method and apparatus for sensing a presence of a magnetic field and/or a magnitude of a magnetic flux density of the magnetic field (25). A direct-current voltage is applied across a first layer of a conductive material (20), so that a direct current flows in a first direction through the first layer. A  second layer of a piezoelectric material (22) is integrated with or positioned adjacent or abutting the first layer. The first layer and the second layer are exposed to or positioned within a magnetic field. A Lorentz force is thus caused, preferably in a direction which is generally perpendicular to the first direction of the direct current and a second direction of the magnetic field to deflect the piezoelectric material thereby causing an output voltage in response to the Lorentz force. A magnetic flux density can be calculated as a function of the piezoelectric output.

Abstract: Demister comprising corrugated plates arranged adjacent to each other substantially vertically, wherein the gas flow containing liquid droplets is forced to pass between the plates in a substantially horizontal direction and with alternate right hand and left hand deflection at each bend of the plates.  The width of the flow path locally in the direction of the flow between any two adjacent plates is varied by a complementary variation of the thickness of the plates from inlet to outlet, so that a sufficiently high linear gas flow velocity for the purpose in question is obtained in each bend. The flow path width and/or the radius of curvature between any two adjacent plates is varied according to a predetermined pattern from inlet to outlet so that alternately at least one intense zone and at least one calm zone appear, so that there is at least one region in which both large and small droplets are separated from the stream and some large droplets are re-dispersed in the stream, and at least one region in which mainly large droplets are separated from the stream, while varying degrees of draining takes place within the same zones.
