Abstract: L'invention concerne un procédé pour extraire des particules en suspension dans un gaz qui sont plus lourdes que ce dernier. Ce procédé consiste à animer le gaz d'un mouvement de rotation dans une chambre (2) délimitée dans un boîtier stationnaire (1) de sorte que les particules soient séparées du gaz par la force centrifuge et soient projetées vers le boîtier stationnaire. La mise en rotation du gaz s'effectue au moyen d'un rotor (8) qui comprend une pile de disques de séparation coniques (22) placés coaxialement les uns par rapport aux autres et concentriquement par rapport à l'axe de rotation (R) du rotor. Ce procédé consiste également à faire passer le gaz à nettoyer à travers des espaces intermédiaires entre les disques de séparation, pendant leur rotation, les particules étant mises en contact par la force centrifuge avec l'intérieur des disques de séparation. Une fois en contact avec l'intérieur de ces disques, les particules se déplacent tout d'abord le long des génératrices des disques de séparation puis le long de membres de guidage inclinés (26) qui sont mis en contact avec l'intérieur des disques. Ces membres de guidage (26) recueillent les particules se déplaçant à travers différents secteurs des disques de séparation et les conduisent vers des zones séparées réparties autour des bords périphériques des disques de séparation. A partir de ces zones, les particules sous forme agglomérée ou coalescée sont éjectées des disques de séparation vers le boîtier stationnaire (1).

Abstract: A method and system for optimizing channel access scheduling for multiple wireless computing devices over a wireless network improves channel access efficiency with respect to a primary channel. An access point, or host computer, includes a host transceiver for receiving control information from the wireless computing devices over a low power channel. Upon receiving the control information, the access point applies a scheduling algorithm to schedule channel access for the wireless computing devices to transmit data over the primary communication channel. The wireless computing devices include a low power radio for receiving scheduling information via the low power channel during idle periods. When the scheduling information is received, the wireless computing device activates its primary channel network interface components to communicate data through the primary channel. When the computing device is idle, the device is configured to power down all of its components with the exception of the circuitry required to power the low power channel. As such, the low power channel is maintained in an active state for receiving scheduling information, such as an access schedule, during both idle and non-idle periods.

Abstract: A round crab pot provides crabs easy access from all directions, while strongly discouraging exit except by crabs of nonallowable small size. The pot may be of variable weight and size for commercial or individual use. The pot frame has an interchangeable top and bottom kept parallel by perpendicular supporting posts. The pot entrance occupies the entire height and circumference. The entrance is formed by a plurality of elongated spring steel rods connected to the top and/or bottom of the frame. The rods are positioned to slant inwardly toward the center of the pot and are connected by spring steel wire and a thin plastic medium. Thus, the entrance exhibits a spring-like tension as crabs enter. In a first variation, the rods are connected to only one end of the frame. Crabs may enter at ground level with the rods extending from the top of the pot, slanting inward and downward toward the center. By reversing the top and bottom, crabs may enter by walking up the rods. Rods of a lesser length may be attached to both the top and bottom of the pot. Crabs walk up the rods to the midpoint of the height of the pot and drop into the center. In both variations, the rods will not allow the crabs to exit.

IPC: A61B19/00
Filed: 2001-11-01
Granted: 2007-01-02
Abstract: A ligation device includes a cannula having first and second extendable members and a Doppler wand. The Doppler wand permits an anatomical vessel, such as a blood vessel, to be located in close proximity to the distal end of the cannula. The extendable members are extendable on two opposite sides of the vessel. A length of ligation material, such as suture material, extends through the first extendable member, and is attached to a detachable element mounted to the distalmost end of the extendable member. The second extendable member includes a snare. The first extendable member includes curved portions which, when the member is extended distally, extend the detachable element into position for the snare so that the snare can grab the loop. Once ensnared, the detachable element is released from the first extendable member, which pulls the ligation material around the vessel. The ligation device does not require prior visualization or dissection of the area around the vessel.
