Abstract: A sliding door system and method is used in an enclosure that defines an inner area shielded against a High-Altitude Electromagnetic Pulse (“HEMP”). The HEMP shielded sliding door system includes an RF shielding door frame, an RF shielding door leaf mounted within an mechanical door leaf frame, a mechanical insertion and retraction assembly attached to both the mechanical door leaf frame and RF shielding door leaf and that operates to extend and retract the RF shielding door leaf into and out of the RF shielding door frame, a drive tube assembly operable to interact with and open and close mechanical door leaf frame (along with RF shielding door leaf) in a sliding motion, and a control assembly, including motor and an air regulator assembly. HEMP shielding air seals are activated when the RF shielding door leaf is inserted into the RF shielding door frame.

Abstract: The present invention is a wide channel door frame cooperating with a wide width knife edge of a door and latching mechanism: to accommodate a gap between finger stock seals when the wide knife edge door is in the open position, to provide electrical connectivity between the door and door frame when the wide knife edge door is received into the wide channel door frame in the closed position, to accommodate ease of manufacturing a straight channel, to accommodate ease of cleaning the channel after installation of the finger stock seals, and to accommodate ease of closing/latching and opening/delatching the door. An alternative embodiment includes a third strip of beryllium copper finger stock seals attached to the base of the channel for increased electrical conductivity or the addition of weather seals for exterior applications. Wide channels and knife edges can be made of desirable material, for example 304 stainless steel.

Abstract: Pneumatic door system of fluid lines, valves, switches, and sensors integrated into hinge mechanisms, door frame, and door connected to a fluid pressurization system to inflate and deflate one or more fluid seals attached to outer perimeter of door adjacent to inner perimeter of door frame to close gap between outer perimeter of door and inner perimeter of door frame to provide radio frequency shielding against, for example, high-altitude electromagnetic pulse. Air seal creates a substantially impermeable barrier against radio frequency transmission, as well as air infiltration, when fully inflated. Separate fluid channels in each component interconnect to act as one fluid circuit or network when door is closed. Pneumatic door system can be fluidly connected to a conventional fluid pressurization system in communication with a programmable logic controller to respond to user input or automatic commands with system overrides to react to system air pressure and air flow conditions.

Abstract: Double paneled door assembly providing RF shielding and soundproofing through the use of two door panels, i.e., back door panel and front door panel, as well as respective back door frame and front door frame. The door panels and door frames are joined together by door pins and door pin bushing as well as frame pins and frame pin bushings, and the double door panels are mounted on the double frames by heavy duty hinges. The use of two door panels and frame panels with a volume of sealed air or other inert gas between the panels aids the RF shielding and soundproofing properties of the door. The bushings act as damping mechanisms to reduce transmission of vibration from the front side of the door assembly to the back side of the door assembly that will ultimately reduce waves permeating into an enclosed room or area.
