Abstract: A head-mounted display system includes a head-mounted display system, comprising a head-mounted display unit, comprising various pad options at various positions on the head including saddle shaped nose pads that deform under a reaction force applied to the apex of the nose to improve load distribution, forehead pads with an associated mounting structure and inserts that affect compliance and/or size, temporal pads configured to lie against the temporal bone which support some of the weight of the head mounted display system and, further stabilizing pads which are located on a rigid portion of the temporal arms and designed to extend along temporal regions of the users head.

Abstract: A fiber placement system comprises a resin impregnation assembly for applying a resin to one or more fiber tows and for infusing the fiber tows with the resin to form one or more inline resin-infused fiber tows. The fiber placement system further includes a fiber placement head comprising at least one cooler configured to receive and cool the in-line resin-infused fiber tows from the resin impregnation assembly. The fiber placement head further includes at least one cutter assembly configured to receive and cut the cooled resin-infused fiber tows and a compaction assembly configured to receive and compact the cut fiber tows onto a tool. A fiber placement method is also provided.
