    Abstract: The invention relates to a reflector comprising a reflector cavity (110) having a front opening for receiving EMR into the reflector cavity (110) for subsequent reflection of the EMR by at least one reflector element (120) arranged within the reflector cavity (110), characterized in that the reflector further comprises a front cover (130) that has high EM R transmittance in at least parts of the EM spectrum, the front cover (130) being arranged to cover the front opening of the reflector cavity (110), and that the front cover (130) and front opening form a gastight seal (140) impermeable to gas to prevent transport of material into and out of the reflector cavity (110) through the front opening.

    Abstract: The invention relates to a suspension assembly (10, 10a, 10b) for supporting a vibration sensitive device (1) in relation to a base (100). The suspension assembly (10, 10a, 10b) comprises: a support arrangement (20) comprising a support plate (21) and a damping support member (22). The support member (22) is configured to receive the vibration sensitive device (1) and the support plate (21) comprises a centre portion (23) and at least two side portions (24) extending with an inclination angle (α) outwardly from the centre portion (23), a base arrangement (30) comprising at least two inclined portions (34) extending essentially in parallel with the at least two side portions (24) of the support plate (21); and at least two wire rope isolators (40), each arranged between a side portion (24) of the support plate (21) and an inclined portion (34) of the base arrangement (30). The invention also relates to a suspension system (80), a vehicle (101), a use of such a suspension assembly (10, 10a, 10b) for supporting a weapon and damping vibrations during transportation.

    Abstract: The present disclosure relates to a method for determining a pose. The method (100) comprises capturing (110), utilizing at least one camera (311), at least a first image (220) at a first pose and a second image (230) at a second pose; obtaining (120) digital surface model, DSM, data (210), wherein said DSM data (210) represents a part of Earth's surface corresponding to said first pose and said second pose; determining (130) at least one set of hypothetical camera poses, wherein each set of hypothetical camera poses is a candidate for the first and the second poses; calculating (140) a matching score for each set of hypothetical camera poses based on matching said first image (220) and second image (230), wherein matching is based on said obtained DSM data (210) and said set of hypothetical camera poses; and determining (150) the first pose based on the matching score of the at least one set of hypothetical camera poses.

    Abstract: The present disclosure relates to a frequency selective camouflage material comprising a backing and a conductive material. The conductive material is patterned onto said backing to form a plurality of regions of conductive material, wherein each region of conductive material is electrically isolated from other regions of patterned conductive material. Each region of patterned conductive material has a diameter in the range of 5 mm to 300 mm. The camouflage material has a transmittance of at least 60% for electromagnetic radiation having a frequency below 200 MHz and at most 40% for electromagnetic radiation having a frequency in the range of 8-20 GHz.
