Abstract
A variable shock absorber assembly of the adaptive or semi-active type or an active actuator wherein the actuator, sensors, electronic controller and valving are integral to and integrated into one assembly and comprise one compact integral unit. Feedback control provides a signal proportional to and indicative of the actuator position and velocity. The compact system is temperature compensated by incorporating temperature sensors into the integrated assembly. The integrated system also provides diagnostics integral to the assembly and an LED mounted on the assembly for providing a visual indication of system condition.
