20120253000 | Microcapsule and Methods of Making and Using Microcapsules - An embodiment of a microcapsule includes a shell surrounding a space, a liquid within the shell, and a light absorbing material within the liquid. An embodiment of a method of making microcapsules includes forming a mixture of a light absorbing material and an organic solution. An emulsion of the mixture and an aqueous solution is then formed. A polymerization agent is added to the emulsion, which causes microcapsules to be formed. Each microcapsule includes a shell surrounding a space, a liquid within the shell, and light absorbing material within the liquid. An embodiment of a method of using microcapsules includes providing phototriggerable microcapsules within a bulk material. Each of the phototriggerable microcapsules includes a shell surrounding a space, a chemically reactive material within the shell, and a light absorbing material within the shell. At least some of the phototriggerable microcapsules are exposed to light, which causes the chemically reactive material to release from the shell and to come into contact with bulk material. | 10-04-2012 |

20110272598 | SURFACE TENSION MEDIATED CONVERSION OF LIGHT TO WORK - Disclosed are a method and apparatus for converting light energy to mechanical energy by modification of surface tension on a supporting fluid. The apparatus comprises an object which may be formed as a composite object comprising a support matrix and a highly light absorptive material. The support matrix may comprise a silicon polymer. The highly light absorptive material may comprise vertically aligned carbon nanotubes (VANTs) embedded in the support matrix. The composite object is supported on a fluid. By exposing the highly light absorptive material to light, heat is generated, which changes the surface tension of the composite object, causing it to move physically within the fluid. | 11-10-2011 |
20130324764 | PROCESSES FOR THE PREPARATION OF DI-(2-AMINOETHYL) FORMAL, DI-(3-AMINOPROPYL) FORMAL, AND RELATED MOLECULES - Disclosed herein are hardeners for use in making cleavable epoxy compositions, including compositions wherein components in contact with epoxy composition can be recovered, as well as methods of making such hardeners. | 12-05-2013 |
20150152043 | SYNTHESIS OF AND COMPOSITIONS CONTAINING DIAMINOACETALS AND DIAMINOKETALS - The present invention relates to the reduction of polycyano compounds to produce polyamines, in particular diaminoacetal and diaminoketal compounds, and their use as curing agents in epoxy resin compositions. The reduction with molecular hydrogen can be carried out using a metal catalyst selected from GROUP VIII and a catalytic promoter. The reduction can include anhydrous or aqueous ammonia. The reaction can be carried out in continuous and batch modes with catalyst and solvent recycling. The epoxy resin composition consisting of an epoxy resin and a polyamine curing agent that can be used in fiber-reinforced composite materials, coating materials, and the like. | 06-04-2015 |

20150260474 | Augmented Reality Simulator - An augmented reality system in which video imagery of a physical environment is combined with video images output by a game engine by the use of a traveling matte which identifies portions of the visible physical environment by techniques such as Computer vision or chroma keying and replaces them with the video images output by the video game engine. The composited imagery of the physical environment and the video game imagery is supplied to a trainee through a headmounted display screen. Additionally, peripheral vision is preserved either by providing complete binocular display to the limits of peripheral vision, or by providing a visual path to the peripheral vision which is matched in luminance to higher resolution augmented reality images provided by the binocular displays. A software/hardware element comprised of a server control station and a controller onboard the trainee performs the modeling, scenario generation, communications, tracking, and metric generation. | 09-17-2015 |
