Abstract: Provided is a latch assembly for a door. The latch assembly includes a housing defining a cavity, a handle movable relative to the housing, a latch disposed in the cavity, the latch having bolt movable between a locked and an unlocked position and a damping mechanism for delaying movement of the latch, wherein the handle is biased in a first position abutting the bolt to hold the bolt in the locked position, and the handle is movable to a second position away from the bolt allowing for movement of the bolt to the unlocked position.

Abstract: A system for monitoring a pressure change within at least one compartment of an aircraft and operating a pyrotechnic device associated with a door latch, includes a securing mechanism arranged in an aircraft door that includes a pyrotechnic actuator and a latch bolt. The system includes the pyrotechnic actuator configured to move the latch bolt when the pyrotechnic actuator is actuated. The system also includes a pressure sensor configured to provide a pressure signal. The system also includes a controller configured to determine a pressure drop representing a decompression event. The system also includes an output driver configured to generate an output signal to actuate the pyrotechnic actuator when the controller determines the occurrence of a decompression event.

Abstract: A shock absorber includes a first end configured to be mechanically fastened to a first component, a second end configured to be mechanically fastened to a second component, a main body, a main shaft, and a primary piston. The primary piston configured to move within the main body and further configured to provide a first damping force by movement of a fluid through the primary piston while the main shaft moves a first distance. The shock absorber also includes a deformable solid material arranged in the main body. The primary piston configured to further move within the main body and further configured to provide a second damping force by deforming the deformable solid material after the main shaft moves the first distance.

Abstract: An aircraft window shade assembly is provided. The assembly includes an inboard shade, an outboard shade, a housing and a cover. The inboard and outboard shades each include a plurality of holes disposed along one side. The housing includes a transparent inboard panel, a transparent outboard panel, a pair of inboard guide slots to receive the inboard shade, a pair of outboard guide slots to receive the outboard shade, an inboard motor and an outboard motor. The inboard motor is coupled to a drive gear sprocket having a cylindrical outer surface and a plurality of teeth extending radially therefrom that mesh with the plurality of holes in the inboard shade, and moves the inboard shade between open and closed positions. The outboard motor is coupled to a drive gear sprocket having a cylindrical outer surface and a plurality of teeth extending radially therefrom that mesh with the plurality of holes in the outboard shade, and moves the outboard shade between open and closed positions.

Abstract: A decompression vent latching apparatus, includes a flap placed on a door opening to a first area from a second area, a housing fastened to the flap on the door, a plunger mounted within the housing, having rotational and lateral movement within the housing, a stop block connected to the plunger, a pair of tip blocks having movement restricted by the stop block connected to the plunger when contacting the stop block, the tip blocks being controlled to be a predetermined distance away from the stop block, and a locking unit connected to the pair of tip blocks providing a closed or open position.

Abstract: An aircraft window shade includes protective transparent window panels, a shade driven by an electric motor, an integral control panel, and support for remote operation. The shade uses dual sprocket drive for positive shade positioning, low wear, and low parts count. The moving shade element remains substantially flat, curving slightly during some phases of positioning. The apparatus replaces a conventional interior window panel and a manual shade with slight change in overall mechanism thickness and weight. Control electronics in the shade can accept a command from a cabin attendant's console to override the local setting and move the shade to a required position, such as fully open for takeoff. The shade supports use of two or more independent shades, each of which can be made of dimming (transparent), diffusing (translucent), or light blocking (opaque) material. The shade is compatible with electrochromic transmittance control technology.

Abstract: An overtemperature protection method and apparatus for a solenoid applies the property of thermal sensitivity of positive temperature coefficient resistors (PTCRs) to prevent heat-induced failures, even in the absence of overcurrent conditions, while effectively preventing nuisance tripping.

Abstract: An apparatus for heat treatment of a wafer is disclosed. The apparatus includes a heating chamber having a heat source. A cooling chamber is positioned adjacent to the heating chamber and includes a cooling source. A wafer holder is configured to move between the cooling chamber and the heating chamber through a passageway and one or more shutters defines the size of the passageway. The one or more shutters are movable between an open position where the wafer holder can pass through the passageway and an obstructing position which defines a passageway which is smaller than the passageway defined when the shutter is in the open position.
