Title: Gene transfer with adenoviruses having modified fiber proteins
Inventor: GORZIGLIA MARIO
IPC: C12N5/10
Filed: 1998-04-30
Abstract: A method of transferring at least one DNA sequence into cells by transducing the cells, in vivo or ex vivo, with a modified adenovirus. The adenovirus, prior to modification, is of a first serotype. In the modified adenovirus, at least a portion of the fiber, and in particular the head portion, is removed from the adenovirus of the first serotype and replaced with a portion, in particular the head portion, of the fiber of an adenovirus of a second serotype. Such method is useful in transducing cells which may be refractory to the adenovirus of the first serotype, yet include a receptor which binds to the head portion of the fiber of the adenovirus of the second serotype.

Title: Digitally certifying a user identity and a computer system in combination
Inventor: LEBOURGEOIS JOHN H
IPC: G06Q20/40
Filed: 1998-10-20
Abstract: Digital certification method in which a first digital signature dependent upon a first user (102) and a first user (102) system in combination (102), is stored accessibly to a certification server (108).  The first user (102) identity can be distinguished by, for example, a PIN provided by the user (102). Subsequently, at a second time when the user (102) desires authorization to complete a transaction (2), the user system (102) generates a second signature dependent upon both the current user identity and current user system in combination.  The certifying system (104) then compares the second signature with the first (1) as stored (108), in order to determine whether to certify the transaction (6).  The certification can accommodate normal computer system component drift. In an embodiment, an inquiring system (106) desiring to confirm the identity of a user (102), issues a challenge code (3) to the user system (102). The user system (102) then digests the user's PIN, individual component signatures as they currently exist on the user's system (102), together with the challenge code (3) to generate the new signature (4). The new signature (4) is transmitted back to the inquiring system (106), which transmits it on to the certification server (104) together with the challenge code (5). The certification server (104) then digests the challenge code with the original signature (1) as previously stored (108), and compares the result to the newly provided signature. If they match, then the user's (102) identity is confirmed (6). If not, then drift criteria can be applied if desired.

Abstract: An intelligent-networked public telecommunications system includes an Internet Connection Interruption (ICI) subscription service that allows a subscriber of a tele-phone line connected to the Internet to receive telephone calls without the need for spe-cial user hardware and user software. In the preferred embodiment, the IN's Service Control Point stores for each customer serviced by the network, an Internet Connection Interruption indicator (a "yes" or "no") indicating whether the customer is currently using the ICI service. When the SCP receives a call for routing to a subscriber and the subscriber's line is busy, the SCP checks its database for the called party's Internet Connection Interruption indicator. If the Internet Connection Interruption indicator is "yes," meaning that the subscriber has elected to receive calls while connected to the Internet, the SCP instructs the Service Switching Point (SSP) to cause the connection to the ISP to be interrupted to receive the call. The Internet Connection Interruption indi-cator is then set to "no," enabling the call to be completed to the subscriber. In the pre-ferred embodiment, the ICI service is activated when the subscriber dials a predefined prefix prior to dialing the number of the Internet Service Provider (ISP).
