20090301945 | SCREEN MODULE FOR VIBRATORY SCREENING APPARATUS - The invention provides a screen module for use on vibratory screening apparatus. The screen module includes: a panel frame having opposed side portions joined by opposed end portions, the end portions being configured for locating the panel frame between spaced panel support rails of the vibratory screening apparatus; at least one intermediate portion extending between the opposed side portions and/or opposed end portions and dividing the panel frame into panel portions; the side portions and said at least one intermediate portion having engagement formations provided on upper surfaces thereof that, together with engagement formations provided on each of the panel support rails of the vibratory screening apparatus, in use, form peripheral panel engagement formations about the panel portions; and at least one pair of screen panels, said screen panels overlying respective panel portions of the panel frame and including complementary engagement formations on an underside periphery thereof for engagement with the peripheral panel engagement formations, defined by the engagement formations of the panel frame and panel support rails. | 12-10-2009 |

20090235070 | Creation of User Digital Certificate For Portable Consumer Payment Device - A method for creating a digital certificate for a user issued by a reliant party, where the reliant party relies on an established cryptographic infrastructure by a registration or certificate authority is described. The registration authority, typically a large financial or credit institution, has already performed the initial overhead steps necessary for a digital authentication system using a chip card. These steps include minting and distributing the chip card, establishing that the key pair and card are given to the right person, and creating the certificate library. The reliant party leverages this cryptographic infrastructure to issue its own digital certificate and certificate chain to a user already having a chip card from the registration authority. Consequently, a user can have additional digital certificates issued to him without having his chip card modified in any way. All additional digital certificates created for a user are stored at a user-specific memory are in a remote certificate library. | 09-17-2009 |
