Patent number: 7714261Abstract: A system and method for protection of aircraft against surface-to-air missiles deploys sensors to provide coverage around an airport The use of a fixed (or slow moving) set of sensors around the airport allows detection of missile threats to all aircraft using the airport without requiring each individual aircraft to be provided with a threat detection system. Information about a detected threat is then typically transmitted in real time directly to the aircraft under threat to allow timely deployment of aircraft-based countermeasures. The detection system and method preferably employ spaced-apart sensors with overlapping fields of view to provide enhanced tracking through triangulation and reduced false alarm rates by redundancy of information. Airborne systems with overlapping coverage may be also used.Type: GrantFiled: April 13, 2006Date of Patent: May 11, 2010Assignee: Rafael Advanced Defense Systems Ltd.Inventors: Yair Bnayahu, Yaakov Lichter, Egon Gersch

Patent number: 7581480Abstract: A distributed ground sensor threat detection system, which is an automated missile warning system designed to provide reliable, timely and accurate missile location information of shoulder-launched SAMs within the volume under surveillance by a network of sensors. Remote sensor nodes position in proximity to an airport runway monitor the area between the nodes to locate threat missiles. Detection information from each remote sensor node is sent to a central processing node which processes the information to determine if a threat missile is launched against a commercial aircraft.Type: GrantFiled: February 25, 2009Date of Patent: September 1, 2009Assignee: The United States of America as represented by the Secretary of the NavyInventors: Mallory John Boyd, Jason R. Allen, William Rodney Ditzler, Richard James Busse, Michael Dennis Barrett

Patent number: 7205520Abstract: 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.Type: GrantFiled: March 2, 2005Date of Patent: April 17, 2007Assignee: United States of America as represented by the Secretary of the NavyInventors: Richard J. Busse, Raymond J. Blattel, Mallory J. Boyd, Michael D. Barrett, William R. Ditzler, Jason R. Allen

Patent number: 6465766Abstract: A sunlight tracking sensor has light sensing faces for receiving light signals from all directions. The light sensing faces are arranged in four quadrants. Each quadrant of the light sensor can sense light signals in two coordinate axes direction. The light signals are processed and used to adjust a light collecting device to track light from the sun.Type: GrantFiled: May 15, 2000Date of Patent: October 15, 2002Inventor: Yaoming Zhang

Patent number: RE39024Abstract: To use a beam splitting optical system smaller than the conventional beam splitters and to set a longer optical path between a concave, reflective mirror and an image plant. A light beam from an object surface travels through a first converging group to enter a beam splitter, and a light beam reflected by the beam splitter is reflected by a concave, reflective mirror to form an image of patterns on the object surface inside the concave, reflective mirror. A light beam from the image of the patterns passes through the beam splitter and thereafter forms an image of the patterns through a third converging group on an image plane.Type: GrantFiled: September 15, 2000Date of Patent: March 21, 2006Assignee: Nikon CorporationInventor: Tomowaki Takahashi

Patent number: 4966177Abstract: 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.Type: GrantFiled: September 28, 1989Date of Patent: October 30, 1990Assignee: Westinghouse Electric Corp.Inventors: Clarence D. John, Jr., Beverly T. Jarabak, Joseph G. Cigich
