“Advanced Concussion Technology™” (Coil Sports Safety Technology™)

“Advanced Concussion Technilogy™” encompasses impact attenuation through a multidimensional, structural “coil” “ring” system using enhanced impact recoil reflection and other control characteristics.

  • The “coils,” continuously linked as a contiguous unit, or as concentric rings, are designed to transfer and dissipate the small to significant impact energy waveforms through “waveform mediation.”
  • Each time the impact energy waveform makes a revolution through the “coils” the energy reduces and reflects, as indicated by the arrows “splashing” over into other coil channels, uniformly into all dimensions.
  • The coil process works in a “compression” manner versus a tension manner, and the mechanism primarily is “dissipation” then “attenuation” of the energy waveform.

Impacts do not have to be helmet to helmet to create issues

  • Impact force resulting in concussions, TBI, CTE, or other head, brain, and neck trauma may come from:
    • helmet to helmet blows, helmet to ground, helmet to chest, shoulder, knee, and so on
    • projectiles, which can also create trauma, and helmets must meet the expectation to energy attenuate in all scenarios
    • IED blasts that also create concussive force wherein the same trauma results from the energy waveform
  • So however it is created – technology must solve the issue of dissipating and energy attenuating the impact waveform

How Energy is Dissipated

The “coils,” continuously linked as a contiguous unit, or as concentric rings, are designed to transfer and dissipate the small to significant impact energy waveforms through “waveform mediation.”

Each time the impact energy waveform makes a revolution through the “coils” the energy reduces and reflects, as indicated by the arrows shown in the previous slide, “splashing” over into other coil channels, uniformly into all dimensions.

Mechanism of Energy Reduction

  • Redirection of mechanical energy (i.e. the helmet impact) perpendicular to the incident blow:
    • Accomplished by mechanical energy transfer from the bulk filler material (i.e. the helmet shell) into the network of interconnected rings
    • Transforms compression and tension effects on the shell into compression and rarefaction in the network of rings
    • Facilitates better dispersion of the mechanical energy from the impact over the entirety of the helmet surface
  • Conventional wave physics also comes into play:
    • The bulk filler material (shell) has significantly less density than the ring material
    • This establishes a boundary zone in the shell leading to wave:
    • Reflection
    • Refraction
    • Dispersion
      • An optimized design would also maximize the critical angle occurrence optimizing energy transfer into the ring network
        • Further leads to decreased energy transfer through the shell

Proof of Concept Testing

  • Tate Technology, LLC proof-of-efficacy tested the “Advanced Concussion TechnologyTM” at Virginia Polytechnic Institute, a NOCSAE-rated facility, using an off-shore manufacturer’s finished product helmets fabricated 100% with carbon fiber where Tate achieved 11% reduction in g-force, SI & HIC testing with the NOCSAE Drop System, and from the Linear Impactor Tate achieved a reduction in Peak Rotational Acceleration from 3-18%, as well as in Peak Rotational Velocity from 3.5-7%.
  • Tate then continued with multiple rounds of testing at Tate’s testing laboratory in April, May, August, and September, and October 2014 using Tate’s internally calibrated NOCSAE Drop System where Tate achieved mean reduction (ten hits/side) in g-force – up to 21%; Severity Index (“SI”) –up to 30%, and Head Injury Criterion (“HIC”) – up to 27%.
  • September 2015, Tate tested ten helmets, five (5) “Control,” and five (5) “Experiment” with the Coil System, using professionally produced carbon fiber lay-up helmets in a pressurized vacuum injection full-mold process.  Tate consistently achieved “statistically significant” test results, with up-to reduction in g-force of 30%, Gadd Severity Index (“SI”) reduction of 49.7%, and in Head Injury Criterion (“HIC”) of 35%.  Remainder analysis will be completed shortly, and throughout testing in 2014-2015 results reach as high as: NOCSAE 24” drop: 72% reduction in the HIC, 79% in the SI, and 42% in the g-force.  NOCSAE 60” drop: 45% in the HIC, 45% in the SI, and 32% in the g-force.
