Abstract: An inventory control system for managing and transporting a subset of tools from a plurality of storage containers. Each of the plurality of storage containers can comprise a plurality of storage locations. Each storage location can store objects, wherein the objects can rest in a tray. Each storage location can comprise at least one image sensing device configured to capture image data of the plurality of storage locations. Each storage location can comprise a data processor configured to receive information representing captured images of the storage locations and data representing the usage or status of the objects associated with the images. The system can further comprise a portable container comprising a plurality of supplemental locations for storing the objects containers. The portable container can be configured to communicate with the plurality of storage locations and configured to reconcile objects shared between the portable container and the plurality of storage containers.

Abstract: A hinge mechanism for attaching ear accessories to a helmet allows an accessory to be attached at a point outside the helmet shell utilizing, for example, a slidable mounting rail, and to reach under the edge of the helmet shell so that the accessory is supported in contact with the wearer's head. The hinge mechanism is well suited for use in connection with military helmets that have a “bulge” or protrusion over the ear.

Abstract: Strap buckles for headgear can be independently adjusted by single-handed operation while the headgear is worn. To tighten the straps, the wearer pulls a strap buckle toward the chin. The adjustment preferably involves a 1:1 length-adjustment ratio, such that the strap is shortened substantially by the amount the wearer pulls on the buckle.

Abstract: A pivot-arm assembly is provided for attaching an ear cup to a mounting feature on an exterior of a helmet. The pivot-arm assembly comprises a mount configured to releasably couple to the mounting feature. An arm has a first end configured to couple to the ear cup and a second end. A hinge is rotatable about a first axis and about a second axis. The hinge is coupled to the second end of the arm and disposed between the second end of the arm and the mount such that the first end of the arm is rotatable relative to the mount about the first axis and the first end of the arm is rotatable relative to the mount about the second axis. A biasing member is coupled to the arm and is configured to spring bias the first end of the arm relative to the mount in a rotatable direction about the second axis of the hinge.

Abstract: A mandible shield comprises at least one panel having a peripheral edge, an inner surface, and an outer surface. The at least one panel is comprised of a ballistics material. A frame is coupled to the at least one panel and covers the peripheral edge of the at least one panel. The frame has at least one window exposing at least a portion of the outer surface of the at least one panel. The frame is configured to at least partially extend over a mandible of a user when the frame is coupled to opposing lateral sides of a helmet.
