Abstract: A prosthetic foot includes a heel member having a heel member shaft extending upwardly from a heel end thereof and a forefoot member having a forefoot member shaft extending upwardly from a toe end thereof. An ankle member receives the heel member shaft and forefoot member shaft so as to allow the heel member shaft and forefoot member shaft to translate in a direction of a wearer's leg in response to an upward force thereon. At least one compressible member is coupled to the ankle member and is in compressible contact with the heel member shaft and/or forefoot member shaft so as to compress in response to the translation thereof.

Abstract: A method for making an actuator capable of dry actuation is provided. The method includes providing a first nanoscale fiber film, providing a second nanoscale fiber film, positioning a solid polymer electrolyte at least partially between and adjacent to the first nanoscale fiber film and the second nanoscale fiber film, and then affixing the solid polymer electrolyte to the first nanoscale fiber film and the second nanoscale fiber film. The nanoscale fiber films may be buckypapers, made of carbon nanotubes. The actuator is capable of dry actuation.

Abstract: A method for forming composite anti-reflective (AR) sol gel-derived coatings includes forming a first chalcogenide compound sol and forming a second chalcogenide compound sol. The first and second sol are mixed to form a mixed sol. The mixed sol is thermally treated at a maximum temperature of no more than 100° C. for (i) drying the mixed sol to form a composite gel and (ii) removing OH? species from the composite gel to form a highly amorphous state AR coating.

Abstract: Remote monitoring of the munition assets is directed to providing a munitions monitoring system and method for monitoring the environment approximate to a munition and transferring data of the environment to a location remote from the munition for storage or processing. A local monitoring device communicates directly with a remote device at a location remote from the munition, the monitoring device being proximate to a munition with a plurality of sensors that monitor the environment of the munition. The local monitoring device can communicate directly with a centralized relay system that is located in the general proximity to a munitions stock pile and/or with a mobile remote device, such as mounted on a vehicle or a hand-held device. The data can be correlated with the operability of the munition.

Abstract: An infrared transmissive article includes an infrared transmissive substrate and a single layer anti-reflective (AR) composite broadband sol gel coating on a surface of the substrate. The AR coating includes a first chalcogenide including compound, and a second chalcogenide including compound intermixed with the first chalcogenide including compound. The percentages of the first chalcogenide and the second chalcogenide in the AR coating are selected to provide a refractive index of the AR coating that approximates the square root of a refractive index of the substrate.
