Abstract: The problem of detecting when a traumatic force has been sustained by the brain of an individual is solved by a shock detection device that can be installed in wearable equipment. The shock detection device can include one or more deformable supports that maintain at least one suspended weight at a specific location within a housing. When a shock of a pre-determined force is sustained by the equipment, the suspended weight and/or the one or more deformable supports will provide an indication that such a shock has occurred. Such indication can be a change in the position or state of the at least one suspended weight and/or the one or more deformable supports. Visual indicators can also be utilized to better signify when a sufficiently forceful shock has occurred.

Abstract: A paneling system is provided herein that concerns interconnecting panels with opposite connecting sides of substantially tongue in groove joint couplings and opposing adjacent connecting sides that are of substantially hook-joint coupling. The hook joint hinders lateral motion while permitting movement in a direction perpendicular to the plane of the interconnected panels to provide ease of installment and removal. The hook joints also provide proper alignment and spacing between panels.

Abstract: The disclosure relates to a system for maintaining an aircraft battery at its optimum operating temperature. A continuous air flow around the batteries is provided. When cooling the batteries, the system operates in a flow-through mode. When heating the batteries, the system may operate in either a flow-through mode or in a closed loop recirculating mode. A thermostat may determine the crossover point between cooling and heating. Several valve and thermostat arrangements are disclosed to convert the air flow from a flow-through system to a recirculating system.

Abstract: A direct plug-in electrical device, such as a charging system including a transformer in a housing, is provided with fastening means adapted to engage anchoring means on a conventional outlet, thereby enhancing the load-carrying capability of the outlet.
