Abstract: The disclosed patterned wavelength-selective material and process for making the patterned wavelength-selective material uses patterned applied adhesive and a structurally weak wavelength-selective material that includes portions that contact the adhesive and break to remain in contact with the adhesive. In one embodiment, the wavelength-selective material comprises an array of sections with cuts at least partially through a wavelength-selective film at each section secured to the adhesive. In another embodiment, the wavelength-selective film comprises a transfer stack of layers.

Abstract: Wavelength-selective films are visibly apparent under the selective wavelength. Wavelength-selective films typically reflect off axis the selected wavelength and therefore can provide high-contrast against a background when applied in a pattern on a substrate. However, it is difficult to apply unique patterned embedded images from film. Disclosed is a cost-effective method and construction of a patterned wavelength-selective image to a substrate. In the disclosed wavelength-selective image, wavelength-selective film particles are applied to an adhesive pattern to create the wavelength-selective image.

Abstract: A means for controlling a rotor of a helicopter utilizes cyclic pitch chas to its rotor blades, accomplished with a cyclic control stick. Cyclic control sticks have been a matter of concern in crashing situations. Prior art cyclic sticks are hinged to that they can be pulled out of the way of a pilot thrown forward and down by an impact. A lanyard actuated by the movement of the pilot's seat pulls the cyclic stick away from the pilot. Since such systems require various mechanisms and pulleys there is a need for an improved cyclic stick. A crashworthy cyclic control stick which is pilot actuated to overcome these difficulties is provided herein.

Abstract: An improved jam-proof control including a cylinder-piston assembly in which the piston is controllably positioned within the cylinder to perform the control function and in which the cylinder snugly envelopes a deformable sleeve so that when the cylinder is deformed by sharp impact, the piston is permitted to continue to reciprocate within the cylinder due to the deformation, either due to frangibility or softness, of the sleeve.
