Abstract: A device and method for selectively illuminating and designating multiple targets in the air or on the ground simultaneously. The device comprises a light source, a switching array and a ball lens. Light from the light source is routed through the switching array, which can addressably output multiple light beams simultaneously. The light beams from the switching array illuminate the backside of a low F-number ball lens. The ball lens creates highly collimated output beams independently (and simultaneously) from any of the output source points of the switching array. These output beams can be used to simultaneously designate multiple targets. When the target illuminating device includes an optional detector array, light scattered from targets can be refracted by the balls lens to impinge on the detector array. Signals from the detector array representing the received light beams can be used for target imaging.

A cooling gel top layer may be included, and the entire assembly may be covered with a fabric top panel and surround. The surround may be vented to facilitate air movement in and out of the mattress.

Abstract: The present invention comprises a method and system for the in-situ cleaning of a heat exchanger tube bundle of carbonaceous deposits. Using the method and system, an organic solvent is brought into fluid communication with one or more heat exchanger tube bundles in a closed system. The closed system is formed at the site of operation of the heat exchanger tube bundles and without having to remove the heat exchanger tube bundles from their shells or other associated equipment. Once the closed system is formed, the organic solvent is brought to a temperature at which it is effective to remove carbonaceous deposits from the heat exchanger tube bundle and flowed through the equipment associated with the heat exchanger tube bundles so as to contact the heat exchanger tube bundles and remove carbonaceous deposits that have formed therein.
