US Patent:

20030065942, Apr 3, 2003

Filed:

Sep 28, 2001

Appl. No.:

09/966006

Inventors:

David Lineman - Houston TX, US
Scott Wierschem - Houston TX, US

International Classification:

G06F011/30

US Classification:

713/201000

Abstract:

A software program capable of creating and managing security policies on a network is disclosed. When a computer administrator selects a set of security controls based on the selected policy, it automatically communicates the controls to computer systems in the network capable of understanding this information. The computer systems can either be audited against this policy or altered to conform to the selected policy. Such changes might include enabling, disabling, deleting, moving or reassigning users, files or objects within the network. The invention further communicates this policy to individuals responsible for understanding the policy via a software program and tracks their reading and understanding of the policy via the same software.

Inventors:

David Lineman - Houston TX, US

International Classification:

G06F007/00

US Classification:

707010000

Abstract:

Methods, systems and computer program products for multi-protocol self-service application access receive a user access request from a user at a server associated with the self-service application. It is determined whether a protocol of the received request is a wireless or wired protocol. The received request is formatted to a common format for processing by the self-service application. A responsive query is selectively transmitted from the self-service application to the user based on the wireless protocol when the received request is a wireless protocol request and based on the wired protocol when the received request is a wired protocol request based on whether the received request is determined to be a wireless or wired protocol. The self-service application may be, for example, a network password and/or account privileges management application and the responsive query may be, for example, a challenge question to validate the user access request.

International Classification:

US Classification:

Abstract:

A well logging system includes a digital threshold crossing data generation system (TCDG System) disposed in a well tool, adapted to be disposed in a borehole, and a digital first motion detection (DFMD) software disposed in a memory of a well truck computer. The TCDG system generates a series of threshold crossings for each analog signal received from a receiver of the well tool, the threshold crossings including a plurality of threshold crossing events for each analog signal and representing compressed versions of digitized analog waveforms. The well logging truck computer receives the threshold crossing data from the TCDG system and executes the DFMD software. When the software is executed, a first set of compressional wave first arrival times are determined from a startup routine in the software using the threshold crossing data. A second set of compressional wave first arrival times are determined from a tracking routine in the software using four different prediction methods and a voting procedure to select the second set of arrival times from among the four predictions. A cycle skip detection routine in the software determines if any cycle skips are associated with either the first or second set of compressional first arrival times.
