  • Patent number: 7243023
    Abstract: A method for balancing vibrations in a rotating machine is provided. The rotating machine has a first and a second plane of imbalance. The method includes determining a first set of solution mass vectors that includes a first solution mass vector for the first plane and a first solution mass vector for the second plane. Each first solution mass vector includes a mass and a phase angle. A first phase difference between a phase angle of the first solution mass vector for the first plane and a phase angle for the first solution mass vector for the second plane is calculated. The first phase difference is compared to a pre-selected value. If the first phase difference is less than the pre-selected value, the first set of solution mass vectors is retained. The first set of solution mass vectors is then incremented to create a second set of solution mass vectors that includes a second solution mass vector for the first plane and a second solution mass vector for the second plane.

  • Patent number: 7142152
    Abstract: A portable, handheld electronic navigation device includes an altimeter and a GPS unit. An internal memory stores cartographic data, for displaying the cartographic data on a display of the navigation device. Accordingly, the device is capable of displaying cartographic data surrounding a location of the unit as determined by GPS and altitude information as determined by the barometric altimeter and GPS. The device provides an enhancement of the calibration and hence the accuracy of barometric altimeter measurements with the aid of derived altitudes from a GPS. The device is able to determine the need for calibration and perform the subsequent computations necessary to facilitate the calibration. Furthermore, the device is able to determine a correction quantity that should be applied to barometric altitude readings, thereby allowing the device to be calibrated while in motion. Both of these features ultimately result in a more accurate determination of altitude.

    Abstract: A system and process for countering the vibrations induced in an aircraft by the windmilling of an engine fan may produce a first electric flight control command for a servocontrol to use in actuating a control surface of the aircraft. The servocontrol is slaved to the first electric flight control command, and the servocontrol's operation is limited to a reduced frequency band. Vibrations induced by the windmilling of the engine fan are monitored, and, when the monitored vibrations exceed a threshold, a second electric flight control command for application to the servocontrol is computed to oppose the induced vibrations. Also, the first and second electric flight control commands are summed to produce an overall control command for the control surface, and the servocontrol is temporarily slaved to the overall control command for operation in a widened frequency band.

  • Patent number: 6651004
    Abstract: A method and apparatus for directing a pursuing vehicle, such as a torpedo, on an intercept trajectory from a launching vehicle to a target vehicle with evasion capabilities. The guidance system bases a solution on vectors on a first Cartesian coordinate system. Evasive maneuvers for the target vehicle are based upon vectors on a second Cartesian coordinate system. The guidance system converts the evasive maneuver to the first coordinate system and then performs an iterative process using initial guidance parameter values to determine, upon convergence of the solutions, final guidance parameters for the target vehicle.

  • Patent number: 6640165
    Abstract: A method of determining an altitude of a flying object. A Blanchard altitude of a flying object is computed. A non-Blanchard reference altitude and a trajectory of the flying object are measured and input to a Kalman filter. In the Kalman filter, the non-Blanchard reference altitude and the trajectory are processed to derive a radius of jet stream curvature. A gradient wind correction factor is then computed as a function of the radius of jet stream curvature. The Blanchard altitude is then corrected in response to the gradient wind correction factor.

  • Patent number: 6604030
    Abstract: An integrated control and monitoring system for airport avionics is made single-point-of-failure impervious by continuously operating pairs of parallel-connected concentrators, Remote Master Workstations and Remote Slave Workstations, and a pair of independent LANs each connecting one of the concentrators of a pair to the Remote Workstations. Each concentrator of a concentrator pair, while in secondary status, monitors the operation of the concentrator in primary status, and whenever it observes a failure of communication will assume primary status and continue to allow ICMS to function in a normal manner. Likewise, another Remote Master Workstation automatically assumes Remote Master Workstation status if it fails to see an operational active master station on the network.

  • Patent number: 6591000
    Abstract: An image filter 1 produces an emphasized output in response to a brightness change between a dark portion and a bright portion of a picked-up image, with a sign of the emphasized output reversing according to a transitional direction of the brightness change between the dark portion and the bright portion. An image filter 2 produces an output representing an angular momentum of respective pixels about a central pixel in a predetermined processing zone set on the picked-up image. The angular momentum is defined by vectorial quantities of pixel values. An image filter 3 produces an output representing an accumulative absolute value of the respective pixels in the predetermined processing zone. An output difference between the image filters 2 and 3 is obtained as an index representing a lane mark.

  • Patent number: 6549828
    Abstract: An aircraft based imaging system. The inventive system includes a sensor mounted in the aircraft in a known orientation, circuitry for acquiring signals generated by the sensor from a scanned area, a system for georeferencing the acquired signals; and a system for compensating for tilt in the acquired signals. In a specific embodiment the sensor is an infrared sensor and the system for georeferencing the acquired signals is a receiver adapted to receive signals from a global positioning system. In the specific embodiment, the means for compensating for tilt in the aircraft includes a gyroscope, a magnetometer and software for controlling the gyroscope to produce signals indicative of the orientation of the aircraft. The software compensates for tilt in the acquired signals and uses the GPS signals to create an accurate mosaic of the images generated by the sensor.

  • Patent number: 6507776
    Abstract: An emergency control system permits an aircraft to recover from a catastrophic loss of cabin pressure even if the pilot becomes incapacitated before he is able to activate an emergency oxygen system. An autopilot system is programmed for rapid descent, in response to a cabin depressurization condition detected by an air pressure sensor, to a flight level where there is sufficient oxygen in the atmosphere to sustain full consciousness. When in the rapid descent mode, the autopilot cuts engine power to idle, reduces the angle of attack, maximizes parasitic drag, and initiates a maximum descent rate without exceeding the aircraft's design limitations. As the aircraft approaches a lower altitude capable of sustaining full human consciousness, the autopilot system increases the angle of attack, reduces parasitic drag, and increases engine power, thereby causing the aircraft to fly level at the lower altitude until the pilot reasserts control of the aircraft.

  • Patent number: 6487495
    Abstract: An improved system and method for specifying physical locations when using applications run on navigation systems or other computer platforms that provide navigation- or map-related functions. When requesting a navigation- or map-related function from such an application, a user specifies a physical location using a keyword instead of specifying the physical location conventionally, such as by street address. A keyword database relates keywords to physical locations. The application uses the keyword database, or a copy thereof, to find data indicating the physical location associated with the keyword specified by the user. Preferably, physical locations are defined in the keyword database in terms of data in a corresponding navigable database. The application then performs the requested navigation- or map-related function using the data indicating the physical location associated with the keyword. The keyword database is built using input from users.
