Abstract: A door actuation system may include an actuation device to move a first door leaf and a second door leaf between an open and a closed position. The actuation device may provide an open preload force in the open position. The actuation device may provide a closed preload force in the closed position. The system may include one or more of: a first engagement member that may contact the actuation device and may allow movement of the actuation device to adjust the open and closed preload force; or the actuation device may be coupled with the first door leaf by a first rod and the second door leaf by a second rod, at least one of the first or second rod may adjust a length of the first or second rod to maintain the open preload force in the open position and the closed preload force in the closed position.

Abstract: A method of moving a charging assembly to engage a vehicle is provided. The method may include driving an upper arm of the charging assembly with an actuator, moving a lower arm and a passive linkage using a force from the upper arm and the actuator, and extending or retracting the passive linkage using the force from the upper arm and the actuator. The method may include sensing one or more electrical characteristics of the charging assembly. The method may include engaging a stop of the passive linkage to allow a substantially vertical movement of a charging head of the charging assembly responsive to the electrical characteristics being below a threshold. The method may include moving the passive linkage away from the stop to allow a substantially horizontal movement of the charging head responsive to the electrical characteristics being at or above the threshold.

Abstract: A charging assembly is provided including a charging head positioned to selectively engage a charging contact of a vehicle, an actuator that may drive an upper arm, and a passive linkage that is passively extendable and retractable in length. The passive linkage may include a stop to limit movement of the passive linkage. The passive linkage may be passively driven by the upper arm and the actuator. A lower arm may be coupled to the upper arm, the passive linkage, and the charging head. The passive linkage may engage the stop to allow a torque from the actuator to move the charging head in a substantially vertical direction while the charging head is not engaging the vehicle. The passive linkage may move away from the stop such that the torque on the lower arm moves the charging head in a substantially horizontal direction while the charging head engages the vehicle.

Abstract: A charging assembly is provided and may include a charging head, an actuator, a linkage, and a connection portion. The charging head may selectively engage a charging contact of a vehicle. The actuator may drive an upper arm. The linkage may be extendable and retractable and may be driven by one or more of the actuator or a weight of the charging assembly. The connection portion may selectively couple the actuator and the upper arm. The connection portion may engage the actuator and the upper arm while the charging head is not engaging the vehicle and allow a torque from the actuator to move the charging head in a vertical direction. The connection portion may disengage the actuator from the upper arm while the charging head engages the vehicle and allow a force from the weight of the charging assembly to move the charging head in a horizontal direction.

Abstract: A Joint Combined Aircrew Systems Tester (JCAST) that can be used to test aircrew integrated life support equipment currently authorized for use by aircrew members of the Air Force, Navy and Army. The JCAST will be capable of Chemical/Biological seal testing of all the Joint Service Aircrew Mask (JSAM) variants including the Type 2 JSAM for high performance aircraft. Like traditional Testers, the JCAST is capable of Performance and Fit Testing of masks at pressure levels, including COMBAT EDGE (Combined Advanced Technology Enhanced Design “G” Ensemble), consistent with aircraft supply levels. The JCAST provides an apparatus and technique for accurately measuring a leak rate for an elastic body such as a chemical mask at 0.5 sccm at 6 IWG. The JCAST is portable and light weight while providing novel leak testing using pressure decay.
