6973571, Dec 6, 2005

Filed:

Jul 3, 2001

Appl. No.:

09/897450

Inventors:

Elizabeth L. Lee - Lafayette CA, US
Phillip R. Schlesinger - San Francisco CA, US

Assignee:

Bank of America Corporation - Charlotte NC

International Classification:

H04L009/00

US Classification:

713168, 713169, 713170, 705 67, 705 70

Abstract:

Embodiments of the present invention described and shown in the specification and drawings facilitate electronic authentication services for banking and other industries. Authentication services, often using Public Key Infrastructure (PKI) technology, are used to confirm the identity of the sender of data and to ensure that the data that was received is identical to the data that was sent. Embodiments of the present invention provide authentication services that may be used by a variety of configurations of entities requesting data authentication and entities responding to those requests. Embodiments of the present invention also support compatibility with commercial data authentication standards, integration with third-party data authentication software such as Secude (for Identrus access), and systems to control data authentication risks.

Abstract:

Systems and techniques for measuring process characteristics including electrolyte distribution in a battery cell. A non-destructive method for analyzing a battery cell includes determining acoustic features at two or more locations of the battery cell, the acoustic features based on one or more of acoustic signals travelling through at least one or more portions of the battery cell during one or more points in time or responses to the acoustic signals obtained during one or more points in time, wherein the one or more points in time correspond to one or more stages of electrolyte distribution in the battery cell. One or more characteristics of the battery cell are determined based on the acoustic features at the two or more locations of the battery cell.
