Publication number: 20160270470Abstract: Presently disclosed embodiments provide a safe and easy way for a child, or other wearer, to independently tighten or loosen the chinstrap on his or her helmet while it remains buckled on his or her head. Disclosed embodiments comprise a knob attached to a side of the chinstrap webbing. The knob is an adjustment mechanism used to loosen or tighten the helmet chinstrap. After the wearer, possibly a child, buckles the helmet chinstrap below his or her chin, the wearer can reach up and twist the knob to loosen or tighten the chinstrap to achieve the proper fit. In some embodiments, each knob may have a cord or the like affixed at one end to an interior assembly and affixed at another end to the chinstrap material. In operation, the chinstrap may be buckled under the chin, and then the knob may be rotated forward, the attached cord is shortened and, thus, the chinstrap may be tightened.Type: ApplicationFiled: November 10, 2015Publication date: September 22, 2016Inventors: ANGUS W.

Patent number: 8555208Abstract: Methods, systems, and tool sets involving reticles and photolithography processing. Several embodiments include obtaining qualitative data from within the pattern area of a reticle indicative of the physical characteristics of the pattern area. Additional embodiments include obtaining qualitative data indicative of the physical characteristics of the reticle remotely from a photolithography tool. In further embodiments qualitative data is obtained from within the pattern area of a reticle in a tool that is located remotely from the photolithography tool. Several embodiments provide data taken from within the pattern area to more accurately reflect the contour of the pattern area of the reticle without using the photolithography tool to obtain such measurements. This is expected to provide accurate data for correcting the photolithography tool to compensate for variances in the pattern area, and to increase throughput because the photolithography tool is not used to measure the reticle.Type: GrantFiled: October 3, 2011Date of Patent: October 8, 2013Assignee: Micron Technology, Inc.Inventor: Craig A.
