Abstract: A system for wireless communication devices using a frequency band shared by other devices, which performs channel and power allocation without operator intervention or a shared coordination device, in which all devices in a local area called a group, perform the same channel and power allocation using their own local data about their network and that of their group, which is shared along with data from the other devices in the group, using the backhaul network to exchange information with other devices in the group for providing better radio communication performance for the members of the group.

Abstract: An imager contains an image sensor with laterally varying spectral response. The imager is scanned over a scene or object to form a spectral image. The spectral responses are repeated at different positions in the field of view so as to reduce the effect of scene nonidealities, such as angle dependence or temporal variation, on the spectral image data. A part of the image sensor may be used for conventional two-dimensional imaging. This part of the image sensor may be used to estimate the scene geometry and scan movement, enabling further improvement in the spectral integrity.

Abstract: A system for enabling tracking and communication between units in a team, typically used for military or rescue operations. The system, known as Command and Control System, has a handheld central unit with a display for showing positions of team units and portable team units having GPS, compass and radio communication function for sending and receipt of positions and alarms and for receiving text messages, a display for showing own positions and bearings. The units have the ability to send data directly or relayed between each other and that each unit can be assigned one or more roles.

Abstract: Method for collecting information from other radio transmitters and/or receivers for the purpose of coordinating and controlling the interference between transmitters and receivers. The method comprises discovering other radio transmitters and receivers in a network. Peer-to-peer communication is used over the Internet when determining relevant neighboring nodes for own communication and performing resource management for the set of radio transmitters and receivers.

Abstract: A device for sorting and concentrating electromagnetic energy impinging a surface of the device, the surface including at least one plasmonics-based surface structure or similar structure of periodic or quasi-periodic surface topography. The device is characterized in that the surface (V) is provided with at least two such surface structures (2), acting as individual concentrator structures, which are at least partially spatially overlapped or superposed.

Abstract: The present invention relates to a helmet and a basic helmet concept with highly flexible construction of use in a number of different situations. The helmet can provide varying degrees of protection and can very easily alternate between the various forms of protection. In addition the individual parts of the helmet can easily be replaced. The helmet consists of an outer helmet with a head-protecting part (1) which essentially covers the side, top and back of the head, a chin guard (39 in front of the lower part of the face and a transparent visor (2) which covers the field of vision of the person using the helmet, together with an inner helmet which is connected to the outer helmet and which inner helmet abuts against the user's head.

Abstract: The present invention relates to ballistic protection for use in personal equipment or in vehicles of various types such as cars, helicopters and boats or for use in permanent or temporary protection of various types in buildings or other fixed or mobile installations. The ballistic protection according to the present invention can be employed as protection against various kinds of low or high-velocity projectiles in addition to which it will be capable of offering protection against splinters and various kinds of fragments which could other wise injure people or damage vehicles or installations if they had the opportunity of penetrating right through an external protective layer. The ballistic protection according to the present invention can further be combined with a drinking water reservoir since an essential part of the protection is a liquid container. The drinking water supply, for example, for a soldier is thereby improved both with regard to available volume and position/carrying capacity.

Abstract: An exhalation system is provided for a helmet or face mask, which helmet or face mask covers the whole or parts of the area of the face's exhalation organs, the nose and mouth, with a chin guard. The system is characterised in that the chin guard is provided with an internal closed cavity which has an opening towards the interior of the helmet or the face mask on the inside of the chin guard and an additional opening towards the outside of the chin guard. The opening towards the interior of the helmet is relatively large and is in the form of one large opening or a small number of large openings which offer the least possible resistance and maintain the velocity of the exhalation air in the best possible manner.

Abstract: A damping device for a gun barrel (1) having a muzzle brake (2) comprises a recoil brake (3) and a vibration damper (9) to prevent natural vibrations in the gun barrel when firing a shot, from propagation to the recoil brake. The connection of the vibration damper to the recoil brake (3) and the gun barrel breech (5) is such that the force transfer coupling between the breech and the recoil brake is reduced with respect to said natural vibrations. The vibration damper (9), which may take the form of a column of Belleville springs (10) is dimensioned so that the damping device as a whole has a rigidity substantially less than the recoil brake alone and forms a vibratory system with a natural frequency substantially lower than the frequency of said natural vibrations of the gun barrel when firing a shot.

Abstract: This invention relates to galvanic seawater cells and batteries and in particular to cathodes which are suitable for use in galvanic cells that use an oxidant dissolved in the electrolyte as depolarizer. An example of such cells are seawater cells which use the oxygen dissolved in the seawater as oxidant. The cell has an inert electrode which consists of a number of conducting fibers (1,3,14) connected to a conducting body (2,4,15). The fibers (1,3,14) have different orientations relatively to each other and to the body (2,4,15). In a preferred embodiment the electrode body (2,4) consists of two or more wires which are twisted together to constitute an electrode stem while clamping the fibers (1,3) in a fixed position between the wires, as in a laboratory bottle brush.
