    UAS Crime Scene Videography - 2 hours with Gerald Baum
    DATE: Friday, 06 December 2024
    TIME: 12 noon - 2 pm EDT (GMT-4)
    COST: Free for NAPARS members;  $5 for non-members
    ACTAR: This event will be submitted for consideration by ACTAR for CEUs. Accredited attendees should be prepared to sign in with i-Attend during the presentation.

    ATTENDANCE CERTIFICATE: All attendees will be able to request an attendance certificate during the show.

    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.

    TBI in Low Severity Crashes 2 hours with Stephen Wagner DC
    DATE: Friday, 10 January 2025
    TIME: 12 noon - 2 pm EDT (GMT-5)
    COST: Free for NAPARS members;  $5 for non-members
    ACTAR: This event has been approved for 2 CEUS by ACTAR. Accredited attendees will need to sign in with the i-Attend during the presentation.

    All attendees will be able to request an attendance certificate during the show.

    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.

    Digital Integration and Building Charts in Excel from a CSV File, 2 hours with W.Bartlett
    DATE: Friday, 07 February 2025
    TIME: 12 noon - 2 pm EDT (GMT-4)
    COST: Free for NAPARS members;  $5 for non-members

    All attendees will be able to request an attendance certificate during the show.

    SUMMARY:

    I will be working with a CSV file recorded during an acceleration/braking event using the G-Field Recorder phone-app. We will digitally integrate the accelerometer data to get speed. If time permits, I'll compare these results with a VBox Sport running at the same time during the test. Topics will include:

    -File structure & saving your work

    -Setting up columns for simple chart generation

    -Borders, gridlines, axis labels, titles, fonts, colors

    -Dual axis charts - managing color & scales

    -Legend, if you must

    -Sharing your chart - printing or inserting into a report
