“COIL SPORTS SAFETY TECHNOLOGY™”

“Coil Sports Safety Technology™” 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 tested with control helmets and helmets with the “Coil Sports Safety TechnologyTM” added
    • These were finished product helmets fabricated with carbon fiber from an off-shore manufacturer for a US Co
    • Tate sealed in the Coil Sports Safety Technology with identical carbon fiber and resin to match the control helmets
    • Note: The original helmet shells were fabricated with significant and wide-ranging inconsistencies in shell thickness, air pockets, and weight adding additional variables
  • Next test round – the technology will be embedded in the manufacturing process produced in the US
    • Tate addressed the procedure to work within current manufacture processes for lay-up, cast, and injection molded helmets
  • Second round of testing proved “proof of concept” in our labs, third round of testing May 2014.
