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

Outwit The Gremlins That Jeopardize Control-System Reliability
In order to maintain complete control-system reliability, you have to be committed. Here are four often-overlooked flaws that can creep into modern automation and control systems while you're not watching

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

    Cabling infrastructure and networking technologies are the main focus of this book that features just enough applications and access technologies coverage to illustrate the trade-offs between the options. Residential Networks presents a "soup to nuts" examination of home networking, from physical layer transmission issues to different types of networks and present-day applications such as voice telephony, data networking, entertainment networks, and home automation.
    Les Baxter and Donald J. Sterling
    There is no better introduction to premises cabling, its components, and its varieties than this basic yet technically accurate presentation of structured cabling systems for both business and home. Now in its Third Edition, Premises Cabling has been updated and revised to reflect the latest developments in the industry, such as the Augmented Category 6 UTP cable, the 10GBASE-T Ethernet standard, application-oriented data center cabling, industrial cabling, wireless networks, and more.
