Patent number: 8423460Abstract: A method whereby vendors and purchasers settle invoices and account for sales taxes, integrated with the drawing, accepting, guaranteeing, endorsing, discounting, presenting, and cash settlement of electronic bills of exchange in all traded currencies (Ebill). Ebills are activated automatically as a direct consequence of the approval of one or more invoices for payment. Acceptance is against a guarantee with a managed credit risk limit or endorsed Ebills. Settlement is also activated by matching a purchase order to a goods received or delivery note or bill of lading. A single instance of each invoice and Ebill is held for all functions required by vendors, purchasers, risk managers, Ebill traders, discounters, guarantors and banks. Trading accounts are represented by a single ledger instance with automated updating of their back-office ledgers. Settlement reconciliation is supported by messages related to individual transactions and by quantified debit advice notes reconciled with credit notes.Type: GrantFiled: April 29, 2005Date of Patent: April 16, 2013Assignee: Obilisk Supplier Finance (UK) LimitedInventors: Alan William Kay, Roy David Hatfield, Jonathan Nicholas Kay, Anthony Alan Harte, Michael Steven Hirst

Patent number: 7971850Abstract: The invention describes devices for controlling fluid flow, such as valves. The devices may include one or more electroactive polymer transducers with an electroactive polymer that deflects in response to an application of an electric field. The electroactive polymer may be in contact with a fluid where the deflection of the electroactive polymer may be used to change a characteristic of the fluid. Some of the characteristic of the fluid that may be changed include but are not limited to 1) a flow rate, 2) a flow direction, 3) a flow vorticity, 4) a flow momentum, 5) a flow mixing rate, 6) a flow turbulence rate, 7) a flow energy, 8) a flow thermodynamic property. The electroactive polymer may be a portion of a surface of a structure that is immersed in an external fluid flow, such as the surface of an airplane wing or the electroactive polymer may be a portion of a surface of a structure used in an internal flow, such as a bounding surface of a fluid conduit.Type: GrantFiled: March 25, 2010Date of Patent: July 5, 2011Assignee: SRI InternationalInventors: Jonathan R.

Patent number: 7921290Abstract: A method is provided to securely authenticate user credentials. The method includes encrypting a user credential with a public key at an access device wherein the public key is part of a public/private key pair suitable for use with an encryption algorithm. The encrypted network user credential is transmitted from the access device to a decryption server where it is decrypted with a private key, the private key being part of the public/private key pair suitable for use with the encryption algorithm. The decrypted user credential is then transmitted from the decryption server to an authentication server for verification. The decryption server typically forms part of a multi-party service access environment including a plurality of access providers, the method including decrypting the user credential of a user proximate an access provider associated with the user credential.Type: GrantFiled: April 5, 2002Date of Patent: April 5, 2011Inventors: Roy David Albert, Jeff Steven Edgett, Singam Sunder, James Marion Underwood

Publication number: 20100270026Abstract: A geophysical model of a subsurface region is generated based on seismic data, e.g., seismic reflection data. Migration and seismic inversion are applied to the seismic data to generate estimates of one or more physical or seismic properties of the subsurface region. Seismic inversion, such as spectral shaping inversion, is applied before or after migrating the seismic data through a variety of techniques that each avoid the amplification of dipping energy while optimizing computational efficiency and/or accuracy.Type: ApplicationFiled: December 5, 2008Publication date: October 28, 2010Inventors: Spyridon Lazaratos, Roy David
