    Abstract: Eyewear exhibiting a variable light transmittance functionality is achieved by including a smart lens incorporating an electrochromic (EC) polymer, switchable between a first state and a second state in response to a voltage selectively applied thereto. The smart eyewear includes the smart lens, a voltage source, and a support. The EC polymer transmits more light in the first state than in the second state, because changing the state of the EC polymer varies the light transmittance of the smart lens. The voltage source is configured to provide the voltage required to switch the EC polymer between the first state and the second state, while the support member is configured to support the smart lens and enable a user to wear the smart eyewear. Embodiments can include sensors and controllers to automate the switching, as well as energy harvesting elements to increase battery life.

    Abstract: A method for making a ductile and porous shape memory alloy (SMA) using spark plasma sintering, and an energy absorbing structure including a ductile and porous SMA are disclosed. In an exemplary structure, an SMA spring encompasses a generally cylindrical energy absorbing material. The function of the SMA spring is to resist the bulging of the cylinder under large compressive loading, thereby increasing a buckling load that the cylindrical energy absorbing material can accommodate. The SMA spring also contributes to the resistance of the energy absorbing structure to an initial compressive loading. Preferably, the cylinder is formed of ductile, porous and super elastic SMA. A working prototype includes a NiTi spring, and a porous NiTi cylinder or rod.

    Abstract: Three green EC materials based on thiophene, and a green EC material based on pyrazine are disclosed. A first thiophene derivative (2,3-Di-thiophen-2-yl-thieno[3,4-b]pyrazine), which was previously investigated as a nonlinear optical material, is here disclosed for its use as an EC material, and for its incorporation into an EC device. Synthesis of two new thiophene derivatives (2,5-di(thien-2-yl)-3,4-di(2,2,2-trifluoro-ethoxy)-thiophene and 2,5-(2,3-dihydro-thieno[3,4-b][1,4]dioxin-5-yl)-3,4-di(2,2,2-trifluoro-ethoxy)-thiophene), and a new pyrazine derivative (2,3-dibenzyl-5,7-di(thien-2-yl) thieno[3,4-b]pyrazine) are also disclosed, since these materials are all able to selectively change to a green color state, and can be polymerized to achieve a green EC polymer.

    Abstract: Electropolymerization of EC monomers is employed to obtain an EC polymer film deposited on a substrate. A first embodiment of a method to produce the film employs cyclic voltammetry alone, while a second embodiment (212) deposits a very thin homogeneous layer using chronoamperometry (216), and then cyclic voltammetry is employed to increase the density of the film (218). Another aspect of the present invention is directed to specific web like configurations for a grid of conductive material deposited onto a transparent substrate. The web like configuration is based either on concentric circles, or on concentric ellipses. Yet another aspect of the present invention is directed to an imaging system including a digital window that is disposed between a prism and a patterned analytic layer.
