  • Publication number: 20130167711
    Abstract: A pyrotechnic countermeasure dispensing system. A first magazine accommodates countermeasures. The first magazine is mountable in a housing such that a contacting body of each countermeasure communicates with a contacting member of launching circuitry. An electronic unit is associated with the launching circuitry for actuating the countermeasure in the first magazine. A second magazine accommodates at least one countermeasure. The dispenser can be loaded with the first or second magazine. The second magazine is mountable in the housing such that a contacting body of the countermeasure communicates with a contacting member of the launching electronic circuitry via an adapter. The adapter includes an electrically insulated plate including a first side including a first point contacting the contacting body and a second side including a second point contacting the contacting member. The first and second points electrically communicate. A launch signal travels from the electronic unit to the contacting member.

  • Publication number: 20120091252
    Abstract: A system for protection of a vehicle against a possible threat approaching the vehicle. A sensor is configured to detect the possible threat and to transmit raw data and to continue the detection as long as there is a possible or confirmed threat. A control unit is configured to receive the raw data transmitted from the sensor and to evaluate the possible threat in view of the raw data to produce and transmit processed information. A counter-measure apparatus is configured to receive the processed information of the threat from the control unit if the evaluation by the control unit confirms that there is a threat. A launcher is configured to receive preliminary processed information of the direction of the threat from the control unit and to receive a launching signal from the control unit for launching the counter-measure apparatus towards the threat when the threat is confirmed.
