Abstract: An active protection system includes a surveillance camera unit, a detection and countermeasure unit, and a central processing unit. The surveillance camera unit is configured to provide an all-round view and image data of a region of interest. The detection and countermeasure unit is configured to detect a potential threat and, upon a confirmation, to activate a countermeasure suitable to at least mitigate the threat. The central processing unit is configured to confirm the detected potential threat based on the image data of the surveillance camera unit and to provide data indicating the confirmed treat.

Abstract: A gas laser is excited by means of a high voltage discharge, at least one firing pulse being applied to a gas discharge tube. The firing pulse can be initiated by a release signal which is applied to an electronic firing unit. Firing pulses then applied to the gas discharge tube until a check-back signal concerning the successful firing of the gas discharge tube is supplied to the electronic firing unit by a detector unit which monitors the operating state of the gas discharge tube.
