Hard facts and conclusive test results from the experts !
UA Solve/University of Alberta Testing G-Force: At the UofA test lab using the ASTM standard drop test F1045 and CAN-CSA Z262.1 The Goose Egg showed significant reductions of G-Force from the standard baseline average of 384g’s down to our average of 115g ‘s with the Goose Egg attached … That’s a 70% decrease. ! Reference: (70% lower than 384 g for Helmet 1, Table 3 and Figure 6).
Acceleration responses: The DCR helmets effectively increased the primary acceleration pulse and decreased peak accelerations in the 1.22 m drops performed here which represent severe head impact. Reference page 13 (5.0) discussion of full report. 70% Reduction: The 70% reductions in peak acceleration suggest that the DCR effectively manages the transfer of impact energy to the headform in the impact scenario of this preliminary work.”( Reference page 13 (5.0) discussion of full report).
Peak Headform Acceleration: The impact testing results indicate that the DCR is capable of reducing peak headform accelerations in rear helmet impacts and further that the presence of the DCR in an impact does not result in helmet damage. (UofA Reference page 13 (6.0) Conclusions of full report).
Without the “Goose Egg”: University of Alberta’s base line ASTM test on a standard helmet averaged at 384g’s. Reference page 9 (70% lower than 384 g for Helmet 1, Table 3 and Figure 6).
With the Goose Egg attached: Nine helmets tested the lowest reduction recorded was 107g using our device, and no higher than 118g. (UofA Reference page 9 (table3) No damage to Helmet)
Helmets with the Goose Egg showed no shell or liner damage after impact. UofA Reference page 11 (4.3) Longer Duration: Showed a 100% increase in duration from 8ms to 16ms. ( 8.3ms for Delta T for helmet 1 ) compared to an average of 16.6ms with the “Goose Egg” (DCR) attached.( UofA Reference page 10 full report)
Dissipation of energy The Goose Egg is designed to break on impact, thus far, no helmet company has been able to come close to our technology. designed to plastically fail, and therefore dissipate energy, in a rear helmet impact. (UofA Reference page 2 executive summary).
