Abstract: An apparatus for applying sunscreen is provided The apparatus includes a housing, a means for adhering the housing to a vertical surface, one or more nozzles coupled to the housing, the one or more nozzles for dispensing sunscreen via a mist, a valve communicably coupled to the one or more nozzles, such that the valve regulates ingress of sunscreen to the one or more nozzles, a pressurized canister of sunscreen removably coupled to the valve via a fastener, such that sunscreen from the canister enters the valve, and a processor communicably coupled to the valve, the processor configured for starting a timer and activating the valve for a predefined period of time after the timer expires.

Abstract: A welder's helmet including a panel of solar cells responsive to light generated by a welding operation to drive a fan incorporated in the helmet structure. The solar cells are mounted on the helmet above the viewing window and the fan is mounted in front of the mask below the viewing window. When a welding arc is struck, the light from the torch impinges on the solar panel and generates sufficient electricity to drive the fan. The fan forces air from the inside of the helmet outward through the front face in a velocity controlled stream carefully directed to prevent smoke and fumes from reaching the helmet, and to also blow the smoke away from the weld site in a particular manner so that visibility of the weld remains clear while not over-oxygenating the weld site. As air is exhausted from the inside of the helmet outward by the fan, fresh air is drawn in around the sides to replace that which is being exhausted to cool the welder and prevent ingestion of fumes and vapors.
