A re-configurable amplifier

Abstract: The present invention relates to an amplifier stage (1) in a radar system comprising an input matching stage (2), a transistor stage (3) and an output matching stage (4). At least one of the matching stages (2, 4) comprises at least two branches, each branch having certain electric properties. The amplifier stage (1) further comprises switching means (33, 34, 35, 36) arranged for switching such that at least one of the branches is electrically connected to the amplifier stage (1).

A device, system and method for changing the direction of emitted light cones

Abstract: The present disclosure relates to an image generator device (100) for changing the direction of at least one emitted light cone at a surface (113), comprising an image generator (130) and a fibre optical faceplate (110) having a first (112) and a second surface (113), the fibre optical faceplate (110) being arranged to transmit light from the image generator (130) so at least a part of light entering the first surface (112) of the fibre optical faceplate (110) exits through the second surface (113) of the fibre optical faceplate (110) and pass through an aperture, wherein the fibre optical faceplate (110) comprises a multitude of optical fibres (111) and light exiting the second surface (113) through optical fibres (111) each form an emitted light cone. A surface structure (120) is arranged at the second surface (113) of the fibre optical faceplate (110), wherein the surface structure (120) is arranged to changing the direction of at least part of the emitted light cones exiting the second surface (113) of the fibre optical faceplate (110) towards the aperture.

Secure data transfer

Abstract: The disclosure relates to a system, devices and methods for distributing and using a communication scheme for way to enable secure communication between communication nodes in a network A method comprises determining (S1), in the network node, a set of available IP addresses and a set of ports, dividing (S2), in the network node, a time frame in time slots, associating (S3), in the network node, each time slot with an IP address, with a port associated with the IP address and with a unique cryptographic key, distributing (S4), from the network node, the communication scheme to the communication node, receiving (S100), in the communication node, the communication scheme and communicating (S300), in the communication node, with another communication node in possession of a corresponding communication scheme by hopping between the IP addresses and ports according to the communication scheme and encrypting the communication using the unique cryptographic key

Initiating device and method for manufacturing such a device

Abstract: An initiating device including at least one detonator, at least one booster charge and an action charge. The at least one booster charge is arranged such that, at the action charge initiates, the booster charge is free from disturbing edge effects that can have a disturbing effect on the action charge. A booster casing in which the booster charge is disposed is configured with a rear cylindrical part having a diameter D 1 , a front conical part delimited by a first circular limit face having the diameter D 1 , and a second circular limit face having a diameter D 2 , wherein the two limit faces are plane-parallel at a distance H 1 from each other, wherein H 1 /D 2 lies within a range 0.5-1.5. Also, a production method for producing the booster charge.

Adaptive mobile camouflage system

Abstract: The present invention relates to a mobile camouflage system (1) for camouflaging vehicles. The system comprises a base camouflage material (13) configured to be securely attached to a vehicle (5) to be camouflaged, and at least one adaptive camouflage area (7) having a camouflage pattern that can be adapted to a surrounding environment. The adaptive camouflage area (7) comprises a patch arrangement (10) having at least one patch (11, 12) that is movable between a first patch configuration in which the adaptive camouflage area (7) exhibits a first camouflage pattern, and at least a second patch configuration in which the adaptive camouflage area (7) exhibits a second camouflage pattern that is different than the first camouflage pattern.
