Abstract: Method and system for extracting metadata from an observed scene comprising the use of high-speed image sensor array observing the scene through a field-of-view, filtering, matching of interesting information defined as activity/incident in the observed scene with a predefined-library, adapting the filtering to enhance frequencies of interest and suppress all others, and extracting metadata of interest.

Abstract: Valve device based on a closing disc formed by disc parts which are movably arranged on activation bolts extending between two stop discs, and where movement of the activation bolts or disc parts in longitudinal direction of the valve device results in that the relative position between the disc parts are changed and the valve device opens or closes.

Abstract: Module-based device for a firearm for sound direction and recoil dampening, which device is arranged for detachable fastening to a barrel of the firearm, which device includes at least one sound directing and recoil dampening module formed by a fastening device for fastening the module-based device to the barrel of the firearm and provided with means for directing/leading sound forward and away from a shooter and bystanders, and reduction for recoil and muzzle flash. The sound directing and recoil dampening module is further adapted for arrangement of at least one sound dampening module.
