Abstract: An airframe leading edge part designed to be replaceable fixed to a structural portion which during use moves through the air. The airframe leading edge part includes first and second longitudinal joint edges adapted to fit the structural portion. At least one joint is provided between the structural portion and at least one of the longitudinal joint edges. The joint is adapted to break in the event of a object strikes and deforms the airframe leading edge part during use. The joint is designed to break at beforehand determined maximum joint strength of the joint. Also a repair method for exchanging a damaged leading edge.

Abstract: The invention relates to a method for building a 3D model of an area of interest on the surface of a planet. The method comprises providing a plurality of 2D images from satellites, where each 2D image out of the plurality of 2D images at least partly covers the area of interest. Also, each subarea of the area of interest is covered by at least two images, taken from different angles, out of the plurality of 2D images. Bundle adjustments are performed for the plurality of 2D images and the area of interest is divided into parts. For each part of the area of interest at least one combination and preferably all possible combinations out of two images covering that part of the area of interest are taken. Said two images are taken from the at least two images, taken from at least two different angles, out of the plurality of 2D images. Further, for each part of the area, point matching correspondence is established for a set of points for each such combination of two images. The sets of points are combined if more than one set of points exists. Even further, for each part of the area, a 3D model of said part of the area of interest is built based on the combined set of points. The 3D models from each part of the area of interest are combined to a 3D model of the whole area of interest. The invention also relates to a system, a computer program and a computer program product.

Abstract: A method for calculating a Time To Go value between a vehicle and an intruding object. First and second images of the object are retrieved at first and second points of time. A scaling factor is selected and the second image scaled with the scale factor. The scaled image is resampled to a set position. Correlation values are calculated between the first image and the resampled scaled image for different horizontal displacements and/or different vertical displacements for the resampled scaled image. A maximum correlation value is found based on the correlation values. Selecting the scaling factor, resampling, calculating the correlation values, and finding the maximum correlation values are repeated a second predetermined number of times. A largest maximum correlation value is found among the maximum correlation values and the scale factor associated with the largest maximum correlation value. The Time To Go is calculated based on the associated scale factor.

Abstract: A method for validating received positional data in vehicle surveillance applications. A signal carrying a Mode S ES message including positional data indicating an alleged position of a vehicle, transmitted from a radio source is received with a radio direction finding antenna of a receiver. A bearing from the receiver to the radio source is estimated utilizing the radio direction finding antenna and received signal. A distance between the receiver and radio source based on a time of flight for a signal travelling between the receiver and radio source at known speed is estimated with a distance measurer including primary radar, laser detector and ranger, and/or secondary surveillance radar. An estimated position of the radio source is calculated based on the estimated bearing and distance. A deviation value indicating a deviation/coincidence between the alleged position is determined according to the received and estimated position of the radio source.

Abstract: The condition of a signal for each block of vehicle track corresponds to that of a bistable memory unit placed in one condition by momentary output of an arrival detector and in its other condition by momentary output of a departure detector. All detectors are actuated by a single type of vehicle-carried exciter. An arrival detector is located near each end of each block. A departure detector is spaced along the track from each arrival detector, in the direction away from the other arrival detector.

Abstract: A document used to assert a personal right has a randomized unique pattern of normally invisible but mechanically detectable material (e.g., finely divided ferromagnetic material) in a zone overlapping any visible indicia identifying the owner. The document is presented to a mechanical reader which scans the pattern along predetermined lines and records resultant output signals, along with an identifying record. Upon subsequent presentation, it is similarly scanned, for comparison with the recording to confirm its authenticity. Methods of producing appropriate patterns are disclosed.

Abstract: In a hydraulic forming tool of the diaphragm type, the punch and the work holder or die member are rigidly mounted on separate pistons that move in communicated cylinders, so that downward movement of one effects upward movement of the other by reason of displacement of fluid from the bottom of one of said cylinders to the bottom of the other. Adequate forming force is assured by metering outflow of fluid from the upper portion of the cylinder having the upgoing piston.
