    Don't Gamble With Control Safety And Reliability: Understand The Benefits And Limitations Of Safety Instrumented Systems.
    As a wise singer once crooned, you have to "know when to hold 'em and know when to fold 'em." But Kenny "The Gambler" Rogers merely had to beat long-shot odds to win at his game.

    Be Smart About Intellectual Property: Understand The Rights, Responsibilities And Pitfalls Of Using Others' Great Ideas
    I’m not an attorney, nor do I play one on TV. Yet my engineering career has often involved legal issues, the most interesting of which is intellectual property (IP).

    Computer Forensics in Non-Computer Investigations
    While the information recorded on event data recorders (EDRs), commonly referred to as vehicle black boxes, is tremendously helpful in determining how a traffic accident occurred and in improving safety, it was not until recently that EDR data was legally challenged in Illinois and ultimately accepted

    How To Test Redundant And Backup Control
    Many of us are inclined to ignore the time honored adage, "If it ain't broke, don't fix it." Sometimes our handyman instincts can't leave well enough alone. Yet that same intuition also encourages us to believe, "If it ain't broke, don't test it." This reluctance is especially evident when it comes to testing the redundant and backup features of our critical control systems
