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: Apparatus for automatically detecting and measuring the energy of laser pes over a wide range of energy levels and in the presence of high ambient light levels. The current produced by a laser pulse striking a photoconductive detector is integrated by a capacitor to obtain a voltage across the capacitor which is proportional to the total energy incident on the detector during the pulse. The total energy of the pulse is then determined by measuring the time from when the capacitor voltage crosses a reference level during current integration to the time when the capacitor voltage, discharging through a resistor recrosses the reference voltage. The leading edge of the capacitor charging voltage is used to couple a high frequency oscillator to the input of a counter. The oscillator is then decoupled from the counter when the voltage of the discharging capacitor crosses a reference level. The count in the counter is transferred to a shift register for transmission to a data processing device.

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.
