Abstract

A damper includes a housing that forms a fluidly sealed cavity for receiving a fluid therein. The fluid is configured to change fluid properties as electrical energy is induced. An electrical subsystem provides electrical energy to the fluid, which is monitored with a control subsystem. The method includes inducing the fluid with electrical energy to change the dampening effects of the damper in real time.

First claim

What is claimed is:

1. A system, comprising:
a damper, having:
a housing;
a piston elastically attached to an inner surface of the housing via an elastomeric material; and
a first fluid chamber and a second fluid chamber positioned within the piston, and on opposing ends of the piston, and in fluid communication with each other via a fluid passage;

a heater configured to provide heat energy to the the first fluid chamber, the heater being in fluid communication with the f…
