Title: Mobile communications service system, mobile communications service method, authentication apparatus, and home agent apparatus
Inventor: KAKEMIZU MITSUAKI
IPC: H04L9/32
Filed: 2000-09-28
Abstract: In a mobile communications service system, various value-added services can be provided for each mobile node. A mobile node transmits a registration request to a foreign agent. The foreign agent transfers a Mobile request message to an authentication process server home agent (AAAH) through an authentication process server foreign agent (AAAF). The AAAH extracts from a service control database a service profile that identifies the value-added services to be supplied to the mobile node. The service profile is distributed to a home agent using a Home agent registration request message, and to a foreign agent using a mobile request message. The home agent and the foreign agent provide services according to the distributed service profiles.

Title: Fuel cell flow-field structure formed by layer deposition
Inventor: DONG ZUOMIN
IPC: H01M8/02
Filed: 1999-04-22
Abstract: A flow-field structure (20, 30, 40, 50, 60, 70) for an electrochemical fuel cell plate is manufactured by sequentially depositing layers of a suspension of formable initially liquid material, typically conductive material, such as screen printing ink in which fine graphite particles are suspended, onto a substrate (22, 32, 41) in conformity with a flow-field wall pattern formed in a screen stencil (116) through the porous mesh of which the suspension is passed. The deposited material bonds with the substrate to form flow-channel boundary walls (24, 34, 44) in a three-dimensional pattern conforming to the stencil pattern. Fuel cell plates with complex flow field topographies may be manufactured using this method. Hydrogen can be used as a fuel gas in fuel cells comprising such plates.

Title: In situ shear strength test facility
Inventor: GOODMAN STEPHEN NORMAN
IPC: G01N3/24
Filed: 2001-01-08
Abstract: The past decade has seen many significant improvements in asphalt pavement technology, particularly through large-scale research efforts such as the Strategic Highway Research Programs in the United States and Canada. However, there remains much room for improvement, particularly in the use of shear properties for the design, construction, monitoring and performance prediction of asphalt concrete pavements.    The primary objective of this investigation was the design, fabrication and validation of an advanced field test facility known as the In-Situ Shear Stiffness Test (InSiSST TM) for asphalt concrete pavements. The development process took a stepwise approach including the analysis of current testing devices and their related deficiencies. The resulting test facility is portable, stable, and rugged - requiring only a single operator with no heavy lifting or complex set-up. Test results are instantly available and initial validation testing has indicated excellent accuracy and repeatability. Future testing with the InSiSST TM facility will provide invaluable input to pavement performance models and may allow the development of a strength or stiffness-based quality control/assurance (QC/QA) specification.

Patent CA-2346735-A1 (CA)
Inventor: HISERODT JOHN C
IPC: A61K39/00
Filed: 1998-09-29
Abstract: This invention provides medicaments and methods for managing cancer using donor cells that are alloactivated in culture. Alloactivated cells are implanted into the bed of a solid tumor and initiate a response by the host against the tumor. Subsequently, alloactivated cells are implanted into the bed of a solid tumor a second time. The two implants work synergistically to confer remarkable benefit to the treated subject, both in terms of management of the cancer and the development of an anti-cancer immune response. The beneficial effects may include regression of the tumor and extended survival. Removal of any residual tumor after the second implant facilitates ongoing resistance to tumor regrowth or metastasis.
