    摘要： A protective covering can protect a surface of a composite article from lightning strikes, wherein the surface includes at least one grounding connection. The covering includes a conductive sheet formed from electrically conductive material configured to be affixed to the composite article over a portion of the surface adjacent the grounding connection; and a perforated overlaminate sheet comprising a dielectric material configured to be affixed to the composite article over the conductive sheet. The perforated overlaminate sheet distributes electrical current of the lighting strikes over an area of the protective covering.

    摘要： A multilayer protective covering can protect a surface from lightning strikes. The covering includes a bottom conductive layer affixed to the surface and having a first opening that is aligned with a grounding connection so that the grounding connection is exposed through first opening and not in contact with the bottom conductive layer. The covering also includes a dielectric layer affixed to the bottom conductive layer and having second opening aligned with the grounding connection so that the grounding connection is exposed through second opening and not in contact with the dielectric layer. The covering additionally includes a top conductive layer affixed to the dielectric layer and covering the grounding connection. The top conductive layer directs electrical current from a lightning strike on the surface to the grounding connection.

    摘要： A sanding system for sanding a surface of a part includes a scanner and a sander. The scanner scans the part to obtain a three-dimensional (3D) surface model of the surface of the part to be sanded. The sander sands the surface of the part. The sander includes a sanding effector that engages and sands the surface of the part and a robot coupled to the sanding effector. The robot moves the sanding effector into engagement with and across the surface of the part based on the 3D surface model to sand the surface of the part.

    摘要： This document generally describes a safe-passage guidance strategy developed in a relative velocity framework to enable a generic aerial robot execute a precision three-dimensional maneuver through a narrow orifice in a wall. The relative sizes of the robot and the orifice can be such that the orifice is only slightly larger than the robot. The orifice can be approximated as an elliptical shape, and analytical nonlinear guidance laws incorporating state-based switching can be derived. Guidance laws can be used to maneuver the robot through both fixed and moving orifices as well as in scenarios when the orifice is closing with time.

    摘要： Provided herein are methods and systems for converting natural gas, and specifically methane, into higher-value oxycarbon products, such as methanol, methyl formate, and formic acid. The natural gas is introduced into an aqueous solution with hydroxyl radicals and reacted in ambient conditions to form the desired products in the presence of a metal catalyst. The methods described herein overcome the “over-activation” dilemma of prior art methods that lead to the formation of undesirable carbon oxide compounds. Methods and apparatus for forming hydrogen peroxide via electrolysis and for forming hydroxyl radicals from the hydrogen peroxide via reaction with ferrous ions are also provided.
