[133]	Patent	Truck cab suspension system	The design comprises air springs, a hydraulic shock absorber, and a height control valve. Also, the system can be fine-tuned to isolate vibrations and still provide adequate stiffness.
[134]	Patent	Vehicle cab suspension system design	The design balances out the twisting force impact on the cab frame by positioning two air springs on either side of the vehicle centerline under the sill and two shock absorbers aligned along the vehicle centerline between the air springs
[135]	Patent	Controlled truck cab suspension system	The invention comprises an air strut and a control module for sensing the distance between the cab and truck frame and selectively pressurizing the air spring in response to changes in that distance
