Abstract: A vehicle wheel alignment system has a plurality of cameras, each camera for viewing a respective target disposed at a respective wheel of the vehicle and capturing image data of the target as the wheel and target are continuously rotated a number of degrees of rotation without a pause. The image data is used to calculate a minimum number of poses of the target of at least one pose for every five degrees of rotation as the wheel and target are continuously rotated the number of degrees of rotation without a pause. At least one of the cameras comprises a data processor for performing the steps of preprocessing the image data, and calculating an alignment parameter for the vehicle based on the preprocessed image data.

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.
