A head unit system for controlling an object includes a secondary object sensor and a head unit device that include shear thickening fluid (STF) and a chamber configured to contain the STF. The chamber further includes a front channel and a back channel. The head unit device further includes a piston housed at least partially radially within the piston compartment and separating the back channel and the front channel. The piston includes a first piston bypass and a second piston bypasses 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 to control motion of the object with regards to a secondary object.

A head unit system for controlling motion of an object includes an environment sensor and a head unit that include shear thickening fluid (STF) and a chamber to contain the STF. The chamber further includes front and back channels. The head unit further includes a piston housed radially within the piston compartment and separating the back channel and the front channel. The piston includes a first piston bypass and a second 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 to abate an internal factor of concern associated with an internal environment as sensed by the environment sensor.

An adjustable damping valve device for a vibration damper includes a pilot stage valve for hydraulic control of a main stage valve. The damping valve device has a check valve arrangement for the rectification of a control volume flow proceeding from working chambers of vibration damper to the pilot stage valve and is characterized in that a pilot stage valve body of the pilot stage valve has a first pressurized surface Di for an incident flow from a first working chamber and a second pressurized surface D.sub.2 for an incident flow from second working chamber.

A shock absorber used with an integrated roll control system is provided. Embodiments include a first shock absorber having a first main piston and a first rebound chamber. Embodiments include a second shock absorber having a second main piston; and a second rebound chamber. Embodiments further include a roll control circuit, wherein the first shock absorber and the second shock absorber are coupled to the roll control circuit in a cross-linked configuration. Compression of the first main piston of the first shock absorber pushes a volume of hydraulic fluid into the roll control circuit and increasing pressure in the roll control circuit. Rebound movement of the second main piston is damped in response to the increased pressure provided by the hydraulic fluid entering the roll circuit and coupled to the second rebound chamber.
