Abstract: A respirator mask wearable by a wearer for protecting the wearer against inhalation of noxious agents (e.g., chemical agents, biological agents, radiological agents, and/or other poisonous or otherwise harmful agents that can cause disease, injury or death), such as a CBRN mask, may be configured to enhance protection of the wearer (e.g., by providing ballistic protection in addition to protecting against noxious agent inhalation) while reducing a burden on the wearer, such as by reducing respiratory resistance, improving visibility, and/or facilitating use of the mask (e.g., connection or disconnection of a filter, conduit, or other air-providing device to or from a breathing interface of the mask).

Abstract: A suspension system for an ATV is provided that includes a torsion control mechanism having a left connecting structure and a right connecting structure. The torsion control mechanism defines an axis of rotation passing through the left and right connecting structures. A left swing arm is fixedly connected to the left connecting structure and a right swing arm is fixedly connected to the right connecting structure, such that the right and left swing arms are pivotable about the rotation axis defined by the torsion control mechanism.
