Detecting objects in images

Abstract: A method and a device for detecting at least one target in an image, wherein the image comprises a set of pixels with a magnitude assigned to each pixel is provided. The method comprises an iterative process until the K+1th target does not show a probability increase above a predetermined threshold value. The method is performed by creating a candidate free image, calculating, for the candidate free image, the probability of there being a target at each pixel, by using Bayes theorem, determining a location of the candidate target K+1 in the image, determining the probability that there is a target at the determined location, by determining the calculated probability of there being a target at the determined location. By performing the above, the most probable locations for targets in the image are located together with the probability that the location holds a true target.

Arrangement and method for autoalignment of a stabilized subsystem

Abstract: The present invention relates to a director mount arrangement for automatic alignment of a subsystem relative to a platform, wherein said director mount arrangement is arranged to pivotably support the subsystem. The director mount arrangement comprises a pivot frame arrangement and a control system. The control system comprises a control unit arranged to generate control signals so as to control the orientation of and stabilize the subsystem. The control signals are generated based on angular rate of subsystem and orientation operating commands provided from an operator. The control unit further generates estimated control signals based on platform orientation information and determine a difference between the control signals and the estimated control signals, wherein the difference is indicative of mechanical misalignments between the subsystem and the platform. The control unit further generates alignment corrections based on the determined difference so as to automatically align the subsystem relative to the platform.

Power converter system providing a load with electrical power

Abstract: A power converter system suitable to provide a load with electrical power, the system comprising; an input voltage terminal; an output voltage terminal; a first power converter unit; a second power converter unit; an input relay unit; an output relay unit; a control unit; wherein the control unit is configured to control the input relay unit and the output relay unit such that the first and second power converter units are engaged alternating at subsequent power ups of the voltage input terminal.

Device for testing of cables

Abstract: The invention relates to a plug device (16,16') for use in testing of conductors in a cable (14,14'), said plug device comprising one or more relay cards having an integrated controller and a power source, wherein the relays on said one or more relay cards form one or more matrixes for relay of measurement signals Force and for relay of sensing signals Sense, said integrated controller/-s being controllable to connect and disconnect conductors coupled to the plug and to open or close relays in the matrixes such as to provide for different types of measurements. The invention further relates to a cable testing device for use with one or more plugs according to any of the claims 1 to 5, said testing device (10) comprises two or more relay cards in the cable testing device, a communication/controlling means for communication with one or more plugs, each relay card comprising a matrix for ForceX and SenseX signals, wherein X=A or B, said A and B signals originate from separate relay cards, said relay cards further adapted to be connected to a cable under test and to one of the plug relay matrixes of the one or more plugs. The invention further relates to a method for testing conductors in a cable (14') wherein both ends of the cable (14, 14') cannot be connected directly to a cable testing device (10), wherein the cable testing device is coupled to one end of the cable under test, said cable testing device having two or more relay cards in the cable testing device (10), a communication/controlling means for communication with one or more plugs, each relay card comprising a matrix for ForceX and SenseX signals, wherein X=A or B, said A and B signals originate from separate relay cards, said signals ForceA and SenseA sent to a cable under test to measure at least one of the conductors of the cable and said signals ForceB and SenseB each to one of the plug relay matrixes of the one or more plugs (16,16').
