Abstract

A head unit system for controlling motion of an object includes a secondary object sensor and a head unit device that includes a shear thickening fluid (STF) and a chamber configured to contain a portion of the STF. The chamber further includes an alternative reservoir and a piston compartment. The head unit system further includes a piston housed at least partially radially within the piston compartment. The piston includes a piston bypass to control flow of the STF between opposite sides of the piston. The chamber further includes a set of fluid flow sensors and a set of fluid manipulation emitters to control the flow of the STF to cause selection of one of a variety of shear rates for the STF within the chamber.
