Patent ID: 8800209

Claim:
A method of controlling the sealing of a door system comprising the steps of: providing a door with an integrally formed fluid channel, a hinge with an integrally formed fluid channel, and a door frame with an integrally formed fluid channel, wherein the integrally formed fluid channels of the door, hinge, and door frame interconnect when the door is in a closed position, wherein the closed position occurs when an outer surface of the door contacts or is in close proximity of a jamb of the door frame, wherein the integrally formed fluid channel of the door frame is connected to a fluid pressurization system, wherein the integrally formed fluid channel of the door is connected to at least one inflatable fluid seal attached to an outer perimeter of the door, wherein the at least one inflatable fluid seal is disposed in a gap formed between an inner perimeter of the door frame and the outer perimeter of the door, and wherein the at least one inflatable fluid seal is in fluid communication with the fluid pressurization system when the door is in the closed position; determining whether the door is in an opened position or the closed position; activating the fluid pressurization system to inflate the at least one inflatable fluid seal to contact the inner perimeter of the door frame before the door is in the closed position; activating a door opening sequence; deactivating the fluid pressurization system; and releasing pressure of the fluid pressurization system causing a reverse flow to deflate the least one inflatable fluid seal.
