    摘要: Active pressure relief valves and methods of use for regulating atmospheric conditions within an interior compartment of a vehicle generally include an active material to effect movement of a flap relative to an opening. The active material has the ability to remember its original at least one attribute such as dimension, shape, and/or flexural modulus, which can subsequently be recalled by applying or removing an external stimulus, as will be discussed in detail herein. Suitable active materials include, without limitation, shape memory alloys, ferromagnetic shape memory alloys, shape memory polymers, piezoelectric materials, electroactive polymers, magnetorheological fluids and elastomers, electrorheological fluids, composites of one or more of the foregoing materials with non-active materials, combinations comprising at least one of the foregoing materials, and the like. Depending on the particular active material, the activation signal can take the form of, without limitation, an electric current, a temperature change, a magnetic field, a mechanical loading or stressing, or the like.

    摘要: A ground cloth is adapted for use between the ground and a ground engagable floor to protect the floor from contamination by the ground. The ground cloth includes a plurality of drain holes for draining to the ground moisture entering between the ground engagable floor and the ground cloth to minimize the retention of moisture between the ground cloth and the floor.

    摘要: An axial positioner capable of yielding to absorb energy under compression or tension loads. The positioner includes an outer tube having first and second ends, a threaded actuator rod extending between the first and second ends and a drive to rotate the actuator rod. A threaded member threadably engaging the actuator rod moves axially between the ends of the outer tube as the actuator rod rotates. The member includes a radial flange extending toward the outer tube. A radially extending load ring spaced axially from the flange is connected to a plurality of axially extending force transmitting elements. A spring positioned between the flange and a load ring expands radially outward against the outer tube when compressed between the flange and the load ring. Loading of the spring against the tube absorbs energy of axial motion of the flange under excessive loads transmitted by the force transmitting elements to the load ring.
