Abstract: A mat for clearing wheels and tires of contaminants as the wheels and tires roll over the mat. The mat includes a tray having a floor, a perimetric wall, and groups or clumps of bristles arranged to incline at an acute angle to the surface of the wheel, perpendicularly to the direction of travel of the wheel. Rows of bristles incline in generally opposing directions. The bristles are anchored to bristle supporting tracks which lie on the floor. Low walls surround and separate the clumps of bristles. The mat may be used as modules in an array. The array may include ramps configured to elevate the wheels above the floor of the tray. The array may include supports for holding the bristles above the tray for cleaning of the tray.

Abstract: Modularized insulation blanket for thermal and/or acoustical insulation. The modularized insulation blanket has a cover formed of a distal layer and proximal layer in sealed mated relationship. The distal and proximal layers are sealed along longitudinal and latitudinal heat-sealed seams that define a plurality of modules. The heat-sealed seam may be creased so as to be foldable and/or perforated to provide a tear line. Within the modules are batting blocks. The blankets may be attached to surface structures such as the interior skin surface of an aircraft fuselage, pipes or other structures with retention systems. The blankets may be formed in an apparatus including a platen, heat seal rollers or heating sealing mechanisms, and edge sealers.

Abstract: An electromechanical flight deck door locking system capable of functioning to keep a cockpit door locked in the event of an interruption in electrical power to the system. The flight deck door locking system includes a locking assembly including a locking component and a manually graspable handle for displacing the locking component. Further, the locking system includes an electronic control panel configured to receive data from an individual seeking access to the cockpit and for electrically locking and unlocking the locking assembly. The locking system also includes a mechanical locking assembly, such as a key lock, whereby a user can use a key to lock and unlock the door if electrical power to the system is unavailable.

Abstract: A ballistic resistant flight deck door assembly for an aircraft is disclosed that also enables pressure equalization within the aircraft in the event of a sudden loss of cabin pressure within the flight deck or cabin. The door assembly includes a door having a plurality of spaced apart panels of ballistic material and a honeycomb support panel. A ventilation area is formed in the door by a plurality of apertures in each of the ballistic panels that are arranged such that no two apertures of the two ballistic panels are perfectly aligned with each other. The blowout panel and ventilation area therefore allows airflow through the door to help equalize pressure within the flight deck in the event of a loss of depressurization of the flight deck without compromising the door's ability to provide ballistic protection for the occupants in the flight deck.
