Abstract: Methods and apparatus for performing repair operations using an unmanned aerial vehicle. The methods are enabled by equipping the UAV with tools for rapidly repairing a large structure or object (e.g., an aircraft or a wind turbine blade) that is not easily accessible to maintenance personnel. In accordance with various embodiments disclosed below, the unmanned aerial vehicle may be equipped with an easily attachable/removable module that includes an additive repair tool. The additive repair tool is configured to add material to a body of material. For example, the additive repair tool may be configured to apply a sealant or other coating material in liquid form to a damage site on a surface of a structure or object (e.g., by spraying liquid or launching liquid-filled capsules onto the surface). In alternative embodiments, the additive repair tool is configured to adhere a tape to the damage site.

Abstract: A wash station enclosure for installation proximate self-service gas pumps and for use by users of said pumps has a cabinet with a top surface with a flush-mounted washbasin therein. A spigot protrudes above the washbasin and communicates with a freshwater tank within the cabinet. An overhang is supported by two vertical supports which are affixed to the sides of the cabinet and support the overhang over and above the washbasin to form a sheltered space. The water within the freshwater tank is kept at a comfortable hand washing temperature by an electric heater. An electric pump communicates with the freshwater tank to cause water to flow from the tank to the spigot in response to activation of a switch. Heat lamps are mounted in the overhang soffit. The heat lamps are activated at the same time as the water flow to illuminate the washbasin and the area around it and to warm the hands of a user of the wash station by infrared radiation.
