Inventor: BREITBART YURI
IPC: G06F21/00
Filed: 2000-05-15
Abstract: A monitoring node is disposed in a data network for monitoring network traffic. As data packets are received by the monitoring node, the monitoring node associates particular users with the data packet by reference to authentication data stored in the monitoring node. The authentication data is received from network authentication sources, and includes an identification of a user and a network address associated with the identified user. The monitoring node, upon receipt of a data packet, compares the network address in the data packet with the network addresses stored as authentication data in order to associate a particular user with the data packet. The monitoring node may also associate a service associated with the data packet. The monitoring node provides usage data to a database which stores aggregate user usage data. The disclosed technique is advantageous in various network applications such as billing, firewalls, gateways, prepaid services, network policy enforcement, and quality of service guarantees.

Title: Automatic sample testing machine
Inventor: MOORE ANDREW
IPC: G01N21/75
Filed: 1997-02-12
Abstract: An automatic sample testing machine for testing samples stored in test cards.  The machine has a test sample positioning system for moving a tray containing a plurality of test sample cards and fluid receptacles among various stations in the machine. The machine has a diluting station for adding a predetermined quantity of diluent to the receptacles as needed. A pipetting station transfers fluid from one receptacle to another. A  vacuum station is provided having a vacuum chamber moveable relative to the tray between upper and lower positions. The chamber cooperates with the tray to make a sealing engagement with the top surface of the tray when it is lowered to the lower position. A vacuum generator supplies vacuum to the chamber. When the vacuum is released from the chamber, the fluid samples are loaded into the cards from the receptacles. The test sample positioning system moves the tray to a cutting and sealing station and then to an incubation station and loads the cards one at a time into a carousel within the incubation station. A test card transport station transports the test cards from the incubation station to an optical reading station, where optical measurements (e.g., transmittance and/or fluorescence optical testing) is conducted on the wells of the card. When the card has been read, it is either moved back to the incubation station for additional incubation and reading or transferred to a stacking card disposal system when the reading is complete.

Abstract: La présente invention concerne une filière comprenant une cavité de filière (12) à palier nul présentant une forme correspondant à la forme de la coupe de l'extrusion demandée. Pour réguler le débit du matériau d'extrusion dans la cavité, on dispose d'une chambre de préformage (17) qui communique avec la cavité de la filière, mais qui est d'une plus grande surface. La profondeur et/ou la largeur de la chambre de préformage varie en plusieurs de ses régions, les dimensions de chaque région étant en rapport avec les dimensions et la position de la région correspondante de la cavité de filière (12). Le principe de fonctionnement est de faire passer la matière d'extrusion par différentes de la chambre de préformage à différentes vitesses, de façon que la matière d'extrusion passe successivement par toutes les régions de la cavité de filière à une vitesse sensiblement uniforme. La profondeur de la chambre de préformage n'est pas supérieure à environ 5 mm, et elle peut descendre jusqu'à environ 0,5 mm. Malgré sa très petite profondeur, la chambre de préformage permet une gestion précise de la vitesse de la matière d'extrusion tout en permettant de conserver une vitesse d'extrusion élevée.
