Appl. No.:

09/413044

Inventors:

Daniel R. Henderson - Palo Alto CA
Yu Chen - Sunnyvale CA
De Chao Yu - Foster City CA

Assignee:

Cell Genesys, Inc. - Foster City CA

International Classification:

G01N 3353

US Classification:

435 71, 4241401, 4242331, 4241311, 4241591, 4242781, 424 931, 530351, 514885

Abstract:

Methods of reducing pre-existing humoral immunity to a viral immunogenic therapeutic agent such as adenovirus, using immunoapheresis are disclosed. Antibodies specific for the viral immunogenic therapeutic agent are selectively removed from the blood of an individual prior to administration of the viral immunogenic therapeutic agent by reaction extracorporeally with an immunosorbent which specifically binds the antibody. After the antibody is selectively removed from the blood, the blood is reinfused into the patient and the viral immunogenic therapeutic agent is administered. The invention also provides kits and compositions for selective removal of anti-viral antibody.

International Classification:

H01L 2312

US Classification:

257704, 257693, 257710, 257728

Abstract:

An apparatus and method for hermetically sealing, EMI shielding integrated circuits for high-speed electronic devices using a combination of microstrip to buried stripline interface for signal transmission from the integrated circuit. The packaging provided comprises a first plurality of microstrips interconnecting the integrated circuit to a plurality of buried striplines exposed on a surface of the main substrate. A ceramic interposer placed over the main substrate âburiesâ a portion of the exposed striplines on the main substrate to thereby insulate these signal paths from a hermetically sealing, and EMI shielding metal lid placed over the integrated circuit. The metal lid and the seal ring brazed over the ceramic interposer thus provide both a hermetic seal and an electric radiation block. A reduction in dispersion due to the buried striplines is also achieved, as well as improving jitter performance.

US Classification:

361752, 361753, 361736, 361735, 361785, 361803, 361796

Abstract:

An integrated high-speed package comprising a package housing having a housing lip and connector having a center pin abutting along a bottom surface of the housing lip. For signal registration of a first substrate to the signal lead, the substrate is âfloatedâ up to the housing lip, which provides an alignment reference to ensure that the top surface of the first substrate is aligned and in direct registration with the signal lead. In another embodiment, the center pin to substrate registration is provided at a top surface of a housing base. The housing base preferably comprises a first portion of a first height and a second portion of a second height. Accordingly, the housing base can accommodate substrates of different thickness while allowing a top surface of the first and a second substrate to be coplanar to facilitate signal registration there between.

US Classification:

713175, 713153, 713168

Abstract:

A method for securing a communication between a peer node and an intermediary peer node in a peer-to-peer network comprises the peer node generating a secured communication request to the intermediary peer node. The intermediary peer node authenticates the peer node in response to the secured communication request. The intermediary peer node issues a signed certificate of authority upon successful authentication.

Abstract:

A environment of server and client systems for revenue generation, where a component is provided for broadcasters to broadcast and/or transmit programming, and where advertisers can create advertisement, and bid for advertising time on the transmitted programming. Advertisers are empowered by the network's ability to perform targeted advertising and/or product placement base on viewer attribute, programming content, and other criteria collected by the environment. Broadcasters are empowered by the network's ability to produce relatively high conversion rate using an viewer interface allowing enabling viewers to perform click-to-buy, click-to-send-lead, and/or click-to-send information, without much disruption to viewing of the transmitted programming. Also disclosed is a business method of generating revenue by utilizing an environment of server and client systems for targeted advertising and/or product placement, where incentives are created by and for broadcasters, advertisers, content providers, creator of the environment, and viewers.

Abstract:

Implementations retrieve a first event that published to a first source of events responsive to updating, deleting, or inserting a first record in a database object that stores records relating to consent. The first event is processed. Processing the first event includes storing in an attribute of a second event an identifier for a second record that relates to the first record and that is in a second database object that stores records relating to consent. If the first record was inserted or updated, processing the first event includes storing in an attribute of the second event one or more identifiers and respective values of fields of the first record based on attributes of the first event.
