Retractable fluid-filled speed bump/vehicle restrictor
First Claim
1. A vehicle restrictor system for the impedance and control of vehicle movement, said system comprising:
- a restriction surface to propose an impact to the vehicle'"'"'s suspension system resulting from the contact between said restriction surface and the vehicle'"'"'s tires;
an arrangement comprising a volume of fluid sustaining said restriction surface, and a flexible fluid reservoir in communication with said volume of fluid, said flexible fluid reservoir having a region for pressing, and an object for pressing, positioned proximate to said region for pressing, and a bidirectional actuator, operative to bi-directionally actuate said object for pressing.

Abstract
Primary vehicle impedance is provided when an actuator exerts a rigid object against a envelope of enclosed fluid to activate the restriction surface by pushing the fluid from the reservoir to the supporting side of the restriction surface. Reversal of the actuator withdraws the rigid object from the enclosed fluid volume, allowing the fluid to return from supporting the deployed restriction surface back to the reservoir. Secondary vehicle impedance is provided when the vehicle'"'"'s tires traverse a predetermined contoured shape of the restriction surface. Continuous contact between the radial tire surface and the ends of the restriction surface is maintained by tapering the ends. Static structural components support the fluid and distribute the forces to the ground as the impact and weight of the vehicle'"'"'s tires are applied to the restriction surface.

13. A vehicle restrictor system for the impedance end control of vehicle movement, said system comprising:
-
a surface to provide an impact to the vehicle'"'"'s suspension system resulting from the contact between said surface and the vehicle'"'"'s fires, said surface having an upper portion, a lower portion and a length; a first volume of fluid underlying said lower portion of said surface end extending approximately said length of said surface such as to provide a distributed support for said surface at a degree of height, wherein said first volume of fluid sets and generally maintains said surface a degree of height impedance through said distributed support; a second volume of fluid in communication with said first volume of fluid, wherein said second volume of fluid acts sea reservoir to said first volume of fluid; a fluid transfer means by which the setting of a degree of height impedance of said surface by said first volume of fluid can be varied through fluid transfer with said second volume of fluid said fluid transfer means comprising at least one plunger positioned approximate to said second volume of fluid and an actuator for pressing said at least one plunger.
