NSI Technology

TECHNOLOGY

NSI has developed an “intelligent helmet liner system” (IHLS) designed to reduce and mitigate Concussion and TBI head injuries caused by impacts to the helmet. Blows to the head, at any level in repetition have been shown to reduce the brain’s capacity to withstand additional impacts and time to recover. Some impacts to the Brain can inflict irreparable damage and normal biophysical functions.

Brain injury tolerance or thresholds generally differs from person to person. Youth has some determination of the damage threshold level however, we only get one brain. TBI has a progressive impact on an individuals’ ability to function normally. Events that occur later in life may not be considered normal. Massive damage can take one’s life. It is imperative that our Military members and Sports Athletes receive the best protection for sustainability and performance superiority.

Through our “Active Damping and Mitigation System” (ADAMS), blows to the head that normally cause brain “injury” are reduced to a safer level.

TBI Mitigation & Protection

The NSI intelligent design offers substantial improvements and benefits over normal helmets Passive Impact Dampening. It is the only design to act as an adjustable cell pressure system for the head where the liner helps protect the brain from impacts, Active Impact Dampening Protection.

The system re-aligns itself after an impact encounter and prepares for another, resulting in an unsurpassed potential to mitigate and reduce brain concussion trauma. Upon impact, sensors placed throughout and under the cells in the helmet provide the microprocessor with the data collected and mitigation as the event takes place, Active Dampening. The system works to abate the g-force, impulse momentum, and impact torque immediately.

NSI Impact Mitigation System

Just as jumping from a building onto an air bag absorbs and dissipates the impact energy NSI Technology performs similarly creating a softer landing for the brain at impact. Our impact cells and electronic systems control and mitigate the impact event.

The impact cells operate independently depending on the impact conditions. For example, if a person is hit in the forehead cell that area is activated and the cells in the rest of the helmet are not. If the person then falls to the ground and hits the back of the head, the impact cells in that location are activated to dissipate the impact energy.

Each impact cell contains a fluid medium, an impact accelerometer, a closed loop force sensor circuit to help manage the impact event, accelerometers to determine the motion of the cell surfaces, a micro -processor and a system to recharge the cells after the impact.

Each cell also reports to a supervisory high performance microprocessor that monitors the decay of the impact energy dynamics. All information is processed in milliseconds by that supervisory microprocessor in a closed-loop configuration. A proprietary control algorithm can utilize real-time telemetry from the sensors. This control sequence takes place at the beginning of impact.

What happens to the Brain when the head takes an impact?

The technology programmed into the NSI Supervisory Microprocessors in the helmet liner system works within milliseconds to mitigate the impact energy.

Without this action the full impact energy goes through the helmet shell, through the normal foam pads compressing them to resistance and against the head or skull. This action takes place within 1-1.2 milliseconds. The Brain will always go to the point of the skull the impact took place. Several other actions can also happen such as the rotation of the skull and angular movement and or the Brain bounces back and forth in the skull possibly caused by an off center impact to the head.

As this resulting action take place the meninges or spinal fluid sack around the Brain is compressed. The rotation of the skull causing the Brain to spin inside the skull and can cause hemorrhaging, this is the most damaging effect to the Brain. The hemorrhaging or bleeding of the Brain does not always happen at the point of impact but can occur anywhere.

When the Brain is put under duress and the synapsis connecting the neurons is stressed the electrons can become inoperable to normal functions which may take several days to recover from the stress to normal. The following are indications of a concussion. Not all people have the same pattern nor do they all have the same threshold of receiving a concussion or how long it takes to recover. The more impacts to the Brain the easier it is to have lower impacts causing a concussion. Any hit to the head can cause a concussion.

Concussion Assessment:

Upon ruling out more severe injury, acute evaluation continues with the assessment of the concussion. First the clinician should establish the presence of any loss of other alterations of consciousness ( LOC ). LOC is relatively rare and occurs in less than 10% of concussive events.

The identification of LOC can be very tricky as the person may lose consciousness very briefly and this event may not be directly observed by others. By definition LOC represents a state of brief coma in which the eyes are typically closed and the person is unresponsive to external stimuli.

Common Signs of a Concussion:

۰ Appearance of being dazed or stunned

۰ Confusion of assignments ( Cognitive Instruction Processing )

۰ Loss of play detail processing

۰ Unsure of game score or time intervals

۰ Clumsy movement

۰ Slow in response to questions

۰ Loss of consciousness

۰ Behavioral and Personality Change

۰ Forgets pre-impact events or ( Retrograde Amnesia )

۰ Forgets events post concussive impact ( Anterograde Amnesia )

۰ Headaches

۰ Nausea

۰ Balance or dizziness

۰ Blurred Vision

۰ Sensitive to light or noise

۰ Sluggishness

۰ Change in sleep pattern

۰ Lack of concentration and short term memory
