  • Patent number: 10627193
    Abstract: Armor for lightweight ballistic protection is made up of composite tiles which can be assembled into modules. The modules can be assembled into panels and can be mounted on vehicles and aircraft and on the walls of shelters. The tiles have core layer(s) of non-homogeneous materials provided by particles of grit distributed in a plastic, preferably rigid polymeric matrix, and which are faced by a layer of high modulus stiff material such as ceramic. The tiles are preferrably backed by elastomeric material and may have sheets of composite material between the elastomeric layer and the non-homogenous core layer. The tiles may be stacked, forming modules and the modules assembled in rows to form panels. An incoming object causes the facing layer to distribute the impact force over a large area of the non-homogeneous grit/polymeric core layer which fractures and absorbs the impact and shock waves, both the compressive direct wave and the tensile wave reflected from the back interface.

  • Patent number: 10606213
    Abstract: An electrical element is fabricated including an optically-detectable pattern of embedded information. An initial physical design is received for an electrical element that performs an electrical function, together with a pattern of information to be embedded in the electrical element. An encoding region is designated within the initial physical design of the electrical element. Information-encoding patterns are determined for one or more thin-film layers in the encoding region to form an optical layer structure that encodes the pattern of information. The initial physical design and the information-encoding patterns are combined into a modified physical design which is used to fabricate the electrical element. The fabricated electrical element performs the electrical function and forms an optically-detectable interference image including the embedded pattern of information when illuminated by incident light.

  • Patent number: 10584413
    Abstract: A thin film deposition system includes a vacuum-preloaded gas bearing deposition head positioned in an external environment. The deposition head has a vertically-oriented output face including a plurality of source openings through which gaseous materials are supplied and one or more exhaust openings. An exhaust pressure at the exhaust openings is less than an ambient pressure, and a source pressure at the source openings is greater than the exhaust pressure, with the pressure at the outermost source openings being greater than the ambient pressure. A substrate positioner applies a vertical force onto a substrate unit, the vertical force passing through a center of gravity of the substrate unit. A motion control system moves the substrate positioner, thereby moving the substrate unit relative to the output face in an in-track direction without constraining the motion of the substrate unit in a direction normal to the output face of the deposition head.
