A system for forming a non-woven, yarn structure for an engineered textile includes a jig having a plurality of upstanding pins and an automatic winding system for winding a plurality of continuous strands of yarn across the jig and around the upstanding pins. The automatic winding system includes a movement mechanism and a winding head coupled with the movement mechanism. The movement mechanism includes one or more motors that are configured to translate the winding head across a central workspace area of the jig. The winding head includes a rotatable base; a plurality of yarn guides arranged in a linear array and extending from the rotatable base, each yarn guide adapted to receive a different one of the continuous strands, and a rotation motor coupled to the rotatable base and configured to selectively rotate the base to alter an orientation of the linear array.

An energy absorber for interposition between a cover and a covered object includes a generally planar matrix of cells. Each of the cells includes a plurality of generally elongate micro-elements interconnected to form a cell micro-structure, with each cell having a respective energy absorption capacity such that an energy absorption capacity of the energy absorber varies across at least one direction. The cells are configured such that impulse of an object with the cover with the energy absorber sandwiched between the cover and the covered object causes a deceleration vs. time response in the object, beginning with a generally linear rise in the deceleration to a peak deceleration within 5 ms after the beginning of the impulse event, followed by a generally nonlinear decrease in the deceleration over a period of not greater than 15 ms to a final target deceleration of not greater than 10% of the peak deceleration.
