Abstract: A system for controlling the test temperature of a unit-under-test inside a centrifuge while minimizing the exposure of attendant testing equipment to the test temperature. A barrier housing is emplaced around the unit-under-test to create a close test environment within which the test temperature can be achieved and maintained by the introduction of a thermal medium. The testing equipment is located on an opposite side of the barrier housing and outside of the close test environment but still within the centrifuge. A fixture negotiates the thermal medium from outside the centrifuge into the close test environment. The barrier housing may be an insulated clamshell housing which opens to fit around the unit-under-test and then closes to create the close test environment. The fixture may include a rotary joint in which the thermal medium moves into a central axis of the centrifuge, through a gimbal, and into the close test environment.

Abstract: A method of testing a sensing device with a sensing mass includes accelerating the sensing device along a circular path about a central axis. The sensing mass of the sensing device may be movable relative to the central axis. The method includes determining a position of the sensing mass of the sensing device via a sensor and shifting the sensing device radially relative to the central axis based at least in part on the position of the sensing mass during acceleration.

Abstract: An apparatus for simulating an oscillating flight path is provided. The apparatus comprises a slide extending along a first axis; a support structure slidably coupled to the slide; and a table connected to the support structure. The support structure is operable to move along the slide. The table is coupled to the support structure and operable to rotate about a second axis orthogonal to the first axis. The table comprises a surface that is parallel to the second axis and that is operable to rotate about a third axis orthogonal to the second axis.

Abstract: A restraint framework for supporting a passenger restraint and for facilitating restraint of a passenger within a vehicle. The restraint framework comprises a lateral support and an upright support. The upright support has a restraint coupling location that facilitates coupling with a passenger restraint. The restraint framework further comprises vehicle couplers to facilitate securing the upright and lateral supports to the vehicle at vehicle attachment points. The restraint framework also comprises a junction to secure the lateral support to the vehicle about a lower vehicle attachment point, and to couple the lateral support to the upright support. The lateral support and/or the junction includes a restraint coupling location that facilitates coupling with the passenger restraint.
