Title: Pair of multifocal progressive spectacle lenses
Inventor: FRANCOIS SANDRINE
IPC: G02B3/10
Filed: 1999-12-22
Granted: 2008-12-09
Abstract: The invention relates to a pair of progressive ophthalmic spectacle lenses;  each lens has an aspherical surface with a far vision zone, an intermediate vision zone and a near vision zone, and good monocular and binocular foveal vision along the principal meridian. At each point of the aspherical surface there is a mean sphere which is proportional to the half sum of the maximum and minimum radii of curvature expressed in meters, and to the refractive index of the lens material. The invention suggests reducing, for a given direction of sight, the absolute value of the difference between a binocularity parameter for two points in the object space. The binocularity parameter is defined for a point in the object space as the relative difference .DELTA.S of the mean sphere for the points of the aspherical surface of the right and left lenses through which the wearer sees said point.

Abstract: Filtering data packets in a manner that promotes efficient flow of data through a communication path. A filter stack includes one or more filter instances that may filter data packets that pass through the filter stack. The filter stack is associated with one or more protocol stacks that function in communication paths between a computing device and a network. When filtering instances are inserted to or removed from a filter stack, associated protocol stacks may remain capable of transferring data. An abstract interface facilitates inserting and removing filter instances by passing data to filter drivers that create filter instances. A filter driver may create multiple filter instances. Filtering operations associated with filter instances may be bypassed based on the direction of data flow, control flow, and characteristics of packets.

Abstract: In electronic commerce (e-commerce) sites that are executed on a single e- commerce application, a user's session is only associated with a single user identity for e-commerce site domain. Acting under a single identity across the site may not be desired. There may be requirements to associate an individual user with one or more separate identities within parts of the site. Aspects of the invention provide a method, system and computer program product for managing multiple user identities for a user of an electronic commerce (e- commerce) site. The method comprises defining the e-commerce site as one or more security domains; and in response to a user's request to invoke an operation of the e-commerce site: determining a one of the one or more security domains to which the operation relates; performing one of a) creating a session and b) reusing a session for the user automatically in accordance with the determined security domain, said session associated with a user identity and a role indicating privileges for invoking operations of the e-commerce site in at least the determined security domain; and persisting said session for reuse. The user's request may be received in association with one or more sessions persisted for the user and a one of the sessions selected in accordance with the determined security domain. In response, either a session may be created or reused. Persisting may comprise providing one or more cookies defining the session to the user for associating with a subsequent request. In accordance with a feature of this aspect, the e- commerce site may define each of the one or more security domains as a hierarchy of organizations and assets owned by the organizations and the determining a one of the one or more security domains to which the operation relates may comprise evaluating the user's request in accordance with the hierarchy.
