Abstract: A roadway monitoring camera cleaning system includes one or more cameras for capturing images through respective viewing surfaces, which are exposed to outdoor environmental conditions. A controller coupled to the cameras receives the images and determines whether a predetermined wash threshold has been met based on any of various indicia of image degradation. Responsive to the wash threshold being met, the controller operates a supply valve to connect a wash fluid source to a conduit, and operates at least one delivery tube valve to connect the supply conduit to at least one delivery tube. Wash fluid is delivered under pressure to the dirty viewing surface as a result. Subsequently, the controller may disconnect the wash fluid source and connect a pressurized source of inert dry gas, in order to dry the viewing surface and to purge the delivery tube of wash fluid.

Abstract: A machine is presented for the cleaning of eyewear. The machine allows the manual or automatic cleaning of eyewear. Under both modes of operation, the eyewear is secured by a user to a support bracket inside a transparent, water-tight cylindrical wash chamber. When in manual mode, the user can direct the spray of wash fluid onto the eyewear by rotating the eyewear using a trackball. When used in automatic mode, the machine washes the eyewear during a preset washing cycle. For both modes, the washing cycle is followed by the drying cycle where a blower directs air onto the lenses for a set time period to blow off excess moisture. The drying cycle concludes with a blower venting the cylindrical wash chamber to remove residual moisture from the wash chamber and the eyewear. After the cleaning, the user removes the eyewear from the machine.

Abstract: A system and method for sanitizing pneumatic conveying piping is provided. The system includes a motorized hose reel with a pig attached to the end of the hose. The pig is smaller in diameter than the inner diameter of the pipe through which it is conveyed. The decreased size of the pig keeps the conveying speed of the pig through the pipes down, while at the same time providing sufficient force to pull the supply hose attached to the pig through the pipes with the pig. The pig of some embodiments of the inventive concept is shaped as a hollow cone or frustoconical shape. Such a shape reduces weight of the pig and also allows the hose to be inserted through the body of the pig with a spray nozzle at the end. The hollow cone shape deflects relatively easily to allow the pig to go around corners or other obstructions. Also, such a pig design automatically centers the nozzle within the pipe during spraying.
