A shoot-back unit and a method for shooting back at a shooter missing a target

Abstract: The present invention relates to a shoot-back unit (5). The shoot-back unit comprises a laser transmitter arranged to transmit a laser beam simulating fired ammunition and a control unit arranged to control the laser transmission of the laser transmitter. The shoot-back unit is characterized in that it comprises means arranged to sense firing of a weapon and a radio receiver arranged to receive hit information and in that the control unit is arranged to, upon sensing firing of the weapon, control the laser transmission in response to the received hit information. The invention further relates to a method for shooting back with simulated or live ammunition at a shooter missing a target.

Aircraft porous metal surface filled with wax and method in production line

Abstract: The present invention regards a method for manufacture of an article (ART) adapted to be mountable on a sub-structure (54) of an aerial vehicle (23), the article comprises an outer surface (3) serving as an aerodynamic surface during use of the article, the method comprises the steps of providing a blank (52) of sheet metal (1, 1'); providing a porous outer layer (7, 7") of said sheet metal; applying a hydrophobic material (11) into said porous outer layer (7, 7") in such way that the thickness of the porous outer layer (7, 7") entirely being impregnated with the hydrophobic material (11); and finishing the outer surface (3) of the article. The present invention also regards the article achieved by the method and also regards a data medium storing program (P) for causing in a production line an automatic or semi-automatic manufacture of the article.

Discussion of a new type of HMD symbology

Abstract: The use of a helmet mounted display system in a fixed-wing fighter will, without no doubt, increase the capabilities of that aircraft. Basic requirement of a helmet system could be fulfilled with a simple austere Helmet Mounted Sight. With new, more advanced, Helmet Mounted Displays that have greater possibilities to display a wide variety of information great emphasis must be made on the analysis of that information. The question of what kind of information that should be displayed in a HMD is certainly not a trivial one. This paper discusses a novel approach of trying to compress a lot of information into few symbols. The goal is to have a decluttered HMD and yet give the pilot superior situation awareness.

Event driven data processing architecture

Abstract: This paper describes a data processing architecture where events and time are in focus. This differs from traditional von Neumann and data flow architectures. New instruction codes are defined and special circuitry is introduced to express and execute event and time operations. This results in reconfigurable software controlled functionality together with real-time performance comparable to dedicated VLSI solutions. The architecture is demonstrated in a real-time radar jammer application. The architecture is promising also for applications as routers and network processors. A prototype system on silicon (SoC), complete with signal memory, instruction memory, four processing units in parallel and interfaces for digitized signals and host computer, is fabricated in 0.35 mum standard CMOS. Time events of signal data on two simultaneous 8-bit links can be programmed with a time resolution of one clock period. Measurements verified correct function and performance above 400 MHz clock frequency at 3.3 Volt supply. Power consumption is 3.6-Watt @320 MHz

Method for transmission in autonomous packet radio networks

Abstract: The invention relates to a method of transmission of information in packet form in a channel between a number of transmitter/receiver stations. According to the method, information is transmitted between the stations using two access methods. The first access method listens to the channel and transmits on the channel after a certain time after the channel has been confirmed to be free. The second access method uses time division. According to the invention, these two access methods are combined in such a manner that a transmission (TC1) using the first access method with acknowledgement request (PF) is followed by acknowledgement transmissions (KV1-KVn) using the second, time division access method, and that acknowledgement information is always received in the transmitter station irrespective of the level of interference on the channel.
