Abstract
An improved system and methods for increasing security at sensitive locations from unwanted third parties through the use of fluidized granular solids.
Claims27
A method of inhibiting access to a location by a third party, the steps comprising:
- forming an enclosure, said enclosure having an opening;
- placing a gas distribution piping array in said enclosure;
- placing fluidizable granular solids in said enclosure in a surrounding relationship to said gas distribution piping array;
- connecting a gas flow generator to said gas distribution piping array;
- activating said gas flow generator to fluidize said fluidizable granular solids when said third party approaches or is located at said opening;
- and
- deactivating said gas flow generator to defluidize said fluidizable granular solids after said third party is at least partially immersed in said granular solids.

A method of inhibiting access to a location by a third party, the steps comprising:
- disposing a fluid bed configuration in a space leading to said location, said space being defined by a perimeter and a volume, and said fluid bed configuration having a gas distribution piping array and a plurality of fluidizable granular solids;
- connecting a gas flow generator to said gas distribution piping array;
- detecting the presence of said third party;
- activating said gas flow generator to discharge gas and fluidize said granular solids;
- and
- deactivating said gas flow generator to defluidize said granular solids after said third party is at least partially immersed in said granular solids.

A method of immobilizing a vehicle comprising the steps of:
- providing an enclosure proximal to a defined surface area, said enclosure defined by an open perimeter and a depth;
- placing a gas distribution array in said enclosure;
- forming a bed of granular solids in said enclosure;
- connecting a gas flow generator to said gas distribution array;
- activating said gas flow generator to fluidize said granular solids when said vehicle is at bed of granular solids or at said defined surface area;
- and
- deactivating said gas flow generator after said vehicle is at least partially immersed in said bed.
