Abstract: An impact activated camera triggering apparatus is used in combination with a camera wherein the apparatus can be mounted on any window of a vehicle having a field of view. The apparatus has an impact activated triggering mechanism which responds to inertial forces from any horizontal direction. Upon sudden impact or deceleration an enclosed inertia member moves relative to the camera causes the release of a spring which directly or indirectly actuates the shutter on the camera.

Abstract: An improved impact activated triggering mechanism for a camera which is mounted on a rear-view mirror of a vehicle. The impact activated triggering mechanism responds to inertial forces from any horizontal direction. Upon sudden impact or deceleration an enclosed inertia member moving relative to the camera causes the release of a spring which directly or indirectly actuates the shutter in the camera.

Abstract: A water and air supported vehicle propelled by the wind. The vehicle includes a long narrow hull (30) that displaces water at low speeds and a plurality of hydrolfoils (36) distending from the hull in communication with the water resisting lateral loads and at high speeds partially supporting the vehicle. An airfoil (38) whose section is suitable for a membrane surface is pivotally attached to the hull and acts to partially support and provide thrust to propel the vehicle. A strut and a plurality of tendons (58), (60), (62), (64) and (72) position the airfoil relative to the hull (30) and articulate the airfoil when manually actuated. The shape of the airfoil tips elements (46) provide vehicle roll resistance when they penetrate the water surface and a payload is supported by a hull torque link (66) and a cantilever beam (90) with a sling (92) positioned therebetween. Other embodiments articulate the hydrofoils in concert or include a payload containing capsule (112).

Abstract: A warpable beam allowing a controlled degree of torsional resistance. The beam is formed with an open cross-section channel-shaped structural element (24) that includes a plurality of planar structural elements (28) or (32) that are positioned within the open section and that define the cross sectional shape. A plurality of diagonal structural element s(46) or (48) positioned transversely within the open section and interfaced with the planar elements transmitting shear across segments. A plurality of points of restraint (50) control the warping of the beam as a result of their relative motion. Further, oppositely inclined diagonal elements in different segments are connected in such a manner as to allow relatively free longitudinal motion while transmitting loads. The beam may be used for bridges or boat docks or as a leading edge spar (57) of an airfoil.
