Classification: CPC F  G | IPC F  G

Claim 10:
11. A head unit device for controlling motion of an object, comprising:
a chamber filled at least in part with a shear thickening fluid (STF);
a piston housed at least partially radially within the chamber, the piston configured to exert pressure against the shear thickening fluid in response to movement of the piston from a force applied to the piston from the object, wherein the chamber includes a front channel and a back channel, wherein the movement of the piston includes one of traveling through the chamber in an inward direction and traveling through the chamber in an outward direction, wherein the piston travels toward the back channel and away from the front channel when traveling in the inward direction, wherein the piston travels toward the front channel and away from the back channel when traveling in the outward direction, wherein the STF is configured to have a decreasing viscosity in response to a first range of shear rates and an increasing viscosity in response to a second range of shear rates, wherein the piston includes:
a piston bypass between opposite sides of the piston that controls flow of the STF between the opposite sides of the piston between the back channel and the front channel when the piston is traveling through the chamber to cause the STF to react with a shear threshold effect; and

a chamber bypass between opposite ends of the chamber, wherein the chamber bypass facilitates flow of a portion of the STF between the opposite ends of the chamber when the piston travels through the chamber in the inward or outward direction.
