    SUMMARY:

    Over the past two years, Gerald Baum at the Dallas Police Department has developed a program utilizing Unmanned Aerial Systems (UAS) to document crash scenes through videography, an innovative and cost-effective approach compared to traditional methods.

    This technology and method allows for detailed aerial views, which has proven highly effective in courtroom presentations, and is supported and developed with the Dallas County District Attorney’s Office. Gerald has given this presentation to law enforcement and government agencies, including LEDA, Council of Governments, and the Texas Public Safety Robotics Summit. And now he'll be sharing the techniques and process with us.

    NOTE: Unlike many of our Zoomies, this one will NOT be recorded, and the slide deck will NOT be available in the reference library. Sorry.

    SUMMARY:

    We will have Stephen Wagner from Portland Oregon to discuss the potential for injury during low-severity crashes and a possible fix for the problem for some patients.

    OUTLINE:

    • Head accelerometer data from human crash testing in 3-5mph delta-V crashes
    • Probability of these causing brain injury
    • 5-8 cases of real world minimal visible damage crashes
    • Several of them have EDR data (or lack of)
    • All of these cases were diagnosed as having concussions with persistent symptoms (post-concussion syndrome) or mild traumatic brain injuries
    • Biomechanics of the spine and factors that are often overlooked.
    • Why it is unlikely that they suffered an actual brain injury
    • What may be a better explanation of the cause of their symptom.

    NOTE: This presentation will be recorded, and placed in the Reference Library.
