Patent number: 7408637Abstract: A system for and method of detecting and characterizing materials using entangled photons is presented. The material may be at a great distances from the detector and may be biological material, complex organic compounds, or inorganic chemicals. The disclosed system and method provide advantages over traditional techniques in that they are largely impervious to atmospheric reduction of probing radiation and in that less probing radiation is required. The reduced probe energy requirement allows for detecting and characterizing sensitive material with significantly reduced material bleaching compared with traditional techniques.Type: GrantFiled: March 24, 2005Date of Patent: August 5, 2008Assignee: General Dynamics Advanced Information Systems, Inc.Inventors: Richard Freeling, Kenneth Augustyn

Patent number: 7406309Abstract: A method for forwarding incoming cellular communications to an aircraft is provided. A request is received to divert incoming calls for a cellular telephone number to a communication system on board an aircraft. The request includes at least a temporary identification code representing a cellular telephone aboard the aircraft. A diversion instruction is associated with the cellular telephone number. The diversion instruction represents an instruction to forward an incoming call for the cellular telephone number to the communications system aboard the aircraft. A state of a cellular telephone associated with the cellular telephone number is considered as busy, regardless of an actual state of the cellular telephone. An incoming telephone call to the cellular telephone number is forwarded, consistent with said considering and in accordance with the diversion instruction, to the communications system on board the aircraft.Type: GrantFiled: April 13, 2001Date of Patent: July 29, 2008Assignee: General Dynamics Advanced Information, Systems, Inc.Inventors: Martin Philip Usher, Andrew Robert Mead

Publication number: 20070278386Abstract: A system and method for imaging one or more objects in the presence of unknown phase and amplitude aberrations is described. Multiple images are collected so as to have measurement diversity and processed using a model-based approach to estimate the aberrations. An incoherent imaging model may be constructed to estimate the dependence of the imagery upon the object and the optical system, including the aberrations. A probability density function may then be calculated using the estimated model. Next, a maximum-likelihood estimate may be calculated and optimized, thus yielding a close approximation of the phase and amplitude aberrations. The estimates may then be used to estimate an image of the object or correct the system for future imaging.Type: ApplicationFiled: June 5, 2006Publication date: December 6, 2007Applicant: General Dynamics Advanced Information Systems, Inc.Inventors: Richard G.

Patent number: 7292342Abstract: Novel spectroscopy techniques using entangled photons are disclosed. In one technique, entangled photons are directed to a sample of interest, while the photons with which they are entangled are resolved according to frequency. The photons transmitted by or reflected from the sample and the frequency-resolved photons are detected. Such detection may be by way of an electronic coincidence counter or a biphoton sensitive material, which absorbs entangled photons while allowing other photon pairs to pass. Detection information is used to derive spectroscopic properties of the sample. In another technique, a Fourier transform spectroscopy technique using entangled photons is disclosed. Entangled photons are directed to a sample, while the photons with which they are entangled are directed to a Michelson interferometer. The photons transmitted by or reflected from the sample and the photons leaving the Michelson interferometer are detected.Type: GrantFiled: July 28, 2004Date of Patent: November 6, 2007Assignee: General Dynamics Advanced Information Systems Inc.Inventor: Thomas Zaugg

Patent number: 7249272Abstract: A method and apparatus for coordinating the activities of multiple computers using a common reference point such as a Global Positioning System pulse-per-second signal. A reload register transmits a reload value to a mission timer. The mission timer generates an interrupt signal based upon the reload value.
