A sealing boot assembly comprises a flexible boot having a first end in sealing engagement with an outer surface of a shaft to define an inner chamber therein. A venting orifice extends from the inner chamber through the flexible boot to ambient and a moisture-blocking, vapor-breathable membrane is disposed across the venting orifice between the inner chamber and ambient to vent gas from the inner chamber during high temperature operation of the shaft and to allow air to returns to the inner chamber upon cooling thereof.

An analytical methodology for the specification of progressive optimal compression damping of a suspension system to negotiate severe events, yet provides very acceptable ride quality and handling during routine events. In a broad aspect, the method provides a progressive optimal unconstrained damping response of the wheel assembly with respect to the body. In a preferred aspect, the method provides a progressive optimal constrained damping response of the wheel assembly with respect to the body, wherein below a predetermined velocity a conventional damper force is retained.

Suspension system with optimized damping response

An analytical methodology for the specification of progressive optimal compression damping of a damper of a suspension system to negotiate a multiplicity of severe events, yet provides very acceptable ride quality and handling during routine events. The damping response of the damper is optimized based upon a progressive optimal constrained events damping function derived from a low envelope curve incorporated with a predetermined damper force acting on the wheel center below a predetermined wheel center velocity, u, based on ride and handling considerations for a given vehicle or vehicle model according to the prior art methodology, whereby the low envelope curve is constructed utilizing a one degree of freedom nonlinear mechanical system model or a quarter car nonlinear mechanical system model.

Suspension system with optimized damper response for wide range of events

A tire pressure monitoring system for a vehicle with at least one tire includes at least one pressure sensor adapted for sensing pressure inside the at least one tire. The system also includes at least one indicator adapted to communicate a stop signal indicating that pressure inside the at least one tire is equal to a target pressure. The indicator is also adapted to communicate a continue signal indicating that pressure inside the at least one tire is unequal to a target pressure. The continue signal is adapted to indicate how close the pressure inside the at least one tire is to the target pressure. The tire pressure monitoring system further includes a controller in communication with the at least one pressure sensor and the at least one indicator. The controller is adapted to determine the target pressure according to a predicted operating condition of the at least one tire.
