Abstract: An ultraviolet target designator and methodology that utilizes ultraviolet radiation from a laser designator to remotely designate targets for various applications. In one embodiment, the ultraviolet laser designator is used to remotely designate a target for insects to fly to so as to collect environmental information. In another embodiment, the ultraviolet laser operates in the solar blind region to remotely designate a target. When used in conjunction with a solar blind camera, the targeting can be performed without detection by infrared or visible detection devices.

Abstract: A vibrating screen apparatus for sizing materials is shown that has a minimum of moving parts therein. A vibrating motor is mounted below longitudinal vibrating bars. The vibrating bars are set on air mounts, which air mounts are between the vibrating bars and cross braces connected to the frame. The vibrating bars press against the underside of a vibrating screen to form a crown therein when the air mounts are inflated. The vibrating screen is stretched between the sides of the frame by tensioning rails. A shroud over the top of the frame is secured in place. Multiple size materials can be produced by stacking multiple vibrating screen apparatuses.
