  • Patent number: 8783509
    Abstract: A method, device and system for metering powder material from a powder material source by a metering device connected to the source. The device is charged from the source with a batch of powder material in a charging configuration. The batch is discharged from the device in a discharging configuration. The source is connected with a metering piston space in the charging configuration via a first channel of a fixed metering channel hub. The volume of the space is controlled between a metering piston and a hub peripheral surface by controlling the piston position in the space, to charge the volume with material by gravity. The metering space is turned around the hub, to the charging configuration. The volume filled with material is enclosed until reaching the discharging configuration. The metering piston space is connected with a discharge opening via a second channel of the hub for discharging the material.

  • Patent number: 8774457
    Abstract: A method and a system for calculating a time to go value between a vehicle and an intruding object. A first image of the intruding object at a first point of time retrieved. A second image of the intruding object at a second point of time is retrieved. The first image and the second image are filtered so that the first image and the second image become independent of absolute signal energy and so that edges become enhanced. An X fractional pixel position and a Y fractional pixel position are set to zero. The X fractional pixel position denotes a horizontal displacement at sub pixel level and the Y fractional pixel position denotes a vertical displacement at sub pixel level. A scale factor is selected. The second image is scaled with the scale factor and resampled to the X fractional pixel position and the Y fractional pixel position, which results in a resampled scaled image.

  • Publication number: 20140166117
    Abstract: The invention aims at pressurising a volume (2) that needs to have a relative air pressure, in comparison with an ambient pressure, where the ambient air pressure can change rapidly and with large amplitude and where the access to pressurised air is limited. This is solved by a half open system comprising two parallel regulators (9) and (17) and two ejectors (15) and (19) working according to a split range control principle. When the relative air pressure difference is above a desired value of the second regulator (17), only the first regulator and the first ejector work. When the relative air pressure difference is below the desired value of the second regulator (17), both regulators (9) and (17) and ejectors (15) and (19) work. In this way the pressure inside the volume (2) can adapt rapidly to the changes in the ambient pressure, without leaking too much air during a static condition.

  • Patent number: 8755950
    Abstract: A termination system that transmits on a cyclic basis, from a control station to an unmanned vehicle, pairs of mutually dependent code and counter values whose dependency is determined by a termination algorithm. The vehicle has knowledge of the algorithm and can hence validate a received code/counter pair using the same algorithm. If the received code/counter pair is invalid, the vehicle can decide to self-terminate. The control station includes a termination actuator that allows the vehicle to be remotely terminated by invalidating, when actuated by an operator, the code/counter pairs that are transmitted to the vehicle.

  • Publication number: 20140131513
    Abstract: A cover for covering a gap between a first structural portion and a second structural portion of an aerial vehicle. A first attachment section is attachable to the first structural portion. A second flexible section covers the gap. The second flexible section includes an abutment portion for abutting against the second structural portion in an operating state. The abutment portion in an unloaded state forms an undulating shape having troughs and crests extending along a curved plane. The curvature of the curved plane essentially corresponds with the curvature of the surface of the second structural portion. The troughs are provided for engagement with the surface in the operating state such that the troughs tend to be flatten out and propagate over the surface pressing down neighboring crests towards the surface for providing a close fit between the cover and the second structural portion.
