“ADVANCED CONCUSSION 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.

Testing Protocols: Control Helmets without vs. Helmets with Coil Sports Safety Technology

Magnetic Suspension

Opposing magnetic forces provide magnetic resistance to impact force with the outer helmet shell 100% hovering/floating over the inner system thereby allowing the outer helmet shell to rotate with multiple degrees of freedom taking the very destructive rotational acceleration & velocity away from the wearers head. The system is not limited by “hard attachment” connections whereas pillars, cones, and other devices in the current art are unitized/attached severely constraining/limiting the ability to rotate.

Tactical Impact Mitigation Over Boot Technology

Protective over boots designed to be used in military and recreational jumps reducing impact forces associated with hitting the ground. The tactical impact over boot uses Tate’s non-Newtonian fluid to address impact force dissipation and attenuation thereby addressing both linear and rotational impact force incurred when engaging the ground.

Footwear Insert Impact Mitigation and Sensor Technology

the footwear insert is designed to energy attenuate impact force from daily footwear use, such as walking, as well as in athletic footwear using Tate’s patent pending non-Newtonian fluid. Additionally, there are two prospective sensor systems to measure and record impact force, as well as vital information including: blood pressure, oxygen saturation rate, heart rate, EKG, respiration rate, skin temperature, hydration and then for fitness, activity and fall detection.
