Copy Protected Optical Media Storage Device
International Patent WO2004057580 / PCT/US03/40479 | Published July 8, 2004 | Inventor
Inventors: William J. Driscoll, William V. Stevenson, Chad M. Larsen
An optical media storage device incorporating a substrate with a data structure including an anomaly region designed to generate read errors, a fingerprint region containing a target hash value, and a program region with an executable application that incorporates hashing algorithms. The device includes metallic reflective and protective layers. The patent applies cryptographic hashing techniques (MD-5 generating 128-bit fingerprints) to optical media authentication. Purposefully embedded physical defects on the disc serve as input for hash value generation, creating a unique fingerprint that cannot be successfully replicated during copying attempts.

System and Method for Virtual Benchmarking
U.S. Patent Application 20070266080 | Published November 15, 2007 | Inventor
Inventors: Steven McNicol, Chad Larsen, Tony O'Neill, Roberto Yslas, Richard Lawrence, Blas Yslas
Assignee: Operations Management International Inc. (CH2MHILL)
Systems and methods for monitoring, analyzing, and virtually benchmarking systems, processes, and assets. The invention decomposes similar processes into specific component levels and stores comparisons in databases, allowing individual components across facilities to be evaluated against virtual benchmarks created from aggregated performance data. The system breaks down complex processes into hierarchical component levels, collects performance metrics from multiple facilities, and generates virtual benchmarks representing optimal achievable performance for facilities with comparable characteristics.

Transportable Computing Environment
U.S. Patent Application 20060288168 | Published December 21, 2006 | Systems Architect
Inventor: Will Stevenson
Assignee: Movai Technologies, Inc.
A system enabling users to store their complete computing environment on portable media and run it virtually on any host computer. The technology uses virtualization to separate user data, executable programs, and system settings, allowing seamless transport across different hardware platforms without modifying the host system. A virtual computing environment manager orchestrates this by using virtual machines, boot loaders, and embedded drivers to make the portable medium bootable on disparate systems. The architecture uses a three-tier data model with a virtual machine layer providing hardware abstraction and a boot mechanism enabling portable storage to boot independently via BIOS.

Computing Environment Assurance Tool
U.S. Patent Application 20060248041 | Published November 2, 2006 | Systems Architect
Inventor: Will Stevenson
Assignee: Movai Technologies, Inc.
A system that enables users to store their complete computing environment on a secondary storage device. The system reconfigures the operating system such that user data access requests are routed to the removable medium, while preserving the user's perception that data remains in its original location. The technology functionally separates three data categories: executable code, configuration settings, and user information, allowing portable computing environments across multiple machines while maintaining transparent data access.
