A new ,head form,, referred to as the Peepsite ,head form, (Figure 7-16) was developed by the U.S. Army Research Laboratory to avoid potential drawbacks of the NIJ head forms. 54 A big shortcoming of the current test head forms is that the clay used to measure the BFD of the ,helmet, upon impact is contained between two solid aluminum parts of the ,head form, (see Figure 7-10).

Helmets, help to protect your brain by reducing the amount of energy ,transferred, to your brain during a crash or fall. That energy or ,force, is generally measured in gravitational ,force, or G’s. Experience a ,force, greater than 300 G’s and you’re considered likely to suffer significant head trauma or death.

MIPS is a brain protection system — engineered to add protection to ,helmets,. The MIPS Brain Protection System (BPS) is found inside the ,helmet,, generally between the comfort padding and the EPS (a high-quality foam used to reduce energy). For certain impacts, the MIPS BPS can reduce harmful forces transmitted to the brain.
