Title: System and method for database access control
Inventor: BAKER BRENDA SUE
IPC: H04L29/06
Filed: 1996-06-06
Granted: 2000-08-08
Abstract: A system and method for selectively controlling database access by providing a system and method that allows a network administrator or manager to restrict specific users (107,108,109) from accessing information from certain public or otherwise uncontrolled databases (i.e., the WWW and the Internet) The invention employs a relational database (114) to determine access rights, and this databas e (114) may be readily updated and modified by an administrator. Within this relational database (114) specific resource identifiers (i.e, URLs) are classifi ed as being in a particular access group. The relational database (114) is arranged so that for each user (107,108,109) of the system a request for a particular resour ce (102,103,104,105) will only be passed on from the local network (110) to a serve r providing a link to the public/uncontrolled database if the resource identifier is in an access group for which the user (101,108,109) has been assigned specific permissions by an administrator. In one preferred embodiment, the invention is implemented as a part of a proxy server within the user's local network. (110)

Filed: 1997-03-03
Granted: 2003-07-22
Abstract: La présente invention concerne une composition et une méthode pour la détermination de l'activité enzymatique ou de la concentration du substrat de l'enzyme dans un échantillon de liquide à analyser; dans cette méthode, l'enzyme catalyse une réaction dans un système de réactifs pour donner une réponse détectable indicative de la concentration de l'enzyme ou du substrat de l'enzyme dans l'échantillon à analyser. Une quantité mesurée d'une protéase capable d'éliminer l'activité enzymatique est comprise dans la composition de réactifs, de manière que lorsqu'une quantité mesurée de l'échantillon à analyser est traitée, la réaction produisant la réponse détectable aura un point final de réaction bien défini. L'invention est particulièrement utile en conjonction avec la détermination des leucocytes dans l'urine dans laquelle les leucocytes sont lysés pour libérer leur élastase leucocytaire humaine qui hydrolyse un ester chromogène pour donner un phénol qui réagit ensuite avec un sel de diazonium pour former un colorant azoïque coloré.

Abstract: Machine permettant de couler en continu de la tôle en bande. Cette machine présente une cavité de coulage orientée verticalement et ouverte vers le haut. Les parois latérales se déplacent vers le bas, enfermant la coulée de métal en fusion. Cette cavité est large dans la partie médiane supérieure et se rétrécit vers les rives et vers le fond pour se réduire à l'épaisseur de la tôle en bande (34) en cours de coulée. Les deux grandes parois de la cavité sont délimitées l'une et l'autre par un réseau de plaques contiguës (38) séparées les unes des autres par un interstice étroit, la surface de chacune des plaques étant subdivisée par des joints de dilatation mince. Chacun de ces réseaux de plaques constitue une approximation à facettes multiples d'une surface à double courbure, dont les changements dynamiques de forme sont facilités par les variations minimes de l'orientation linéaire et angulaire de chacune des plaques par rapport aux autres au fur et à mesure de leur défilement vers le bas selon la cavité du moule.

Filed: 1998-06-04
Granted: 2005-03-08
Abstract: A wireless communication system is configured to allow for the provisioning of partitioned telecommunication service to subscribers. A wireless switch contains a partition table which associates a service provider with each wireless terminal which has the switch as its home switch. When providing telecommunication services to a subscriber using a wireless terminal, the switch provides such services using resources associated with the service provider associated with the subscriber. In one embodiment, such a resource may be a subscriber profile database such that multiple service providers maintain separate subscriber profile databases connected to the switch. The switch, upon determining the service provider associated with a subscriber requesting service, will retrieve the subscriber's profile from the subscriber database associated with the identified service provider. The switch then provides services in accordance with the retrieved profile.
