Abstract: A ground based launch detection system consisting of a sensor grid of electro-optical sensors for detecting the launch of a threat missile which targets commercial aircraft in proximity to a commercial airport or airfield. The electro-optical sensors are configured in a wireless network which broadcast threat lines to neighboring sensors with overlapping field of views. When a threat missile is verified, threat data is sent to a centrally located processing facility which determines which aircraft in the vicinity are targets and send a dispense countermeasure signal to the aircraft.

Abstract: A system for ultrasonically cleaning tubes includes an elongated cleaning tank adapted to hold a quantity of detergent-containing water and a series of transducers mounted on the bottom wall of the tank in a generally linear arrangement extending between opposite end walls of the tank. The transducers generate ultrasonic cavitational energy within the water in the tank. An inclined upper tube entry ramp supported above the tank guides delivery of tubes in single file fashion into the tank to a reversely inclined middle tube transfer ramp. The inclined middle ramp guides transfer of tubes in single file fashion into the water in the tank and to a lower tube soak ramp having a tube accumulating terminal end. The lower ramp feeds the tubes across the tank within the water and above the transducers therein to its tube accumulating end such that each tube will pass through and be cleaned by the cavitation energy in the water.
