    Abstract: An actuator, especially for a vehicle protection system, comprises at least one wire (14) variable in shape depending on temperature made from a shape memory alloy and an elongate pyrotechnical element (12) connected to the shape-variable wire (14) so that upon ignition of the pyrotechnical element (12) the wire (14) is heated and experiences a change of length. The vehicle protection system is, for example, an airbag system comprising an airbag and a regulating mechanism for the internal airbag pressure, wherein the wire (14) of the actuator (10) is connected to the regulating mechanism so that a change of shape of the wire (14) exerts a force on the regulating mechanism.

  • Patent number: 9028769
    Abstract: The oxygen generation system includes a chemical oxygen generator that creates oxygen through an exothermic chemical reaction that creates sufficient heat to pose a serious risk to a user. The oxygen generation system therefore includes a containment layer to permit safer administration of oxygen from a chemical oxygen generator by shielding a user from and/or dissipating the heat generated by the chemical generator. The oxygen generation system may be handheld and portable for use in extreme, remote, and/or hostile conditions, locations, environments, and situations with a simple activation method easily operated under stress without any preparation or maintenance.

    Abstract: Fireworks launching system and method are provided, which enable safe and accurate control in launching fireworks. The fireworks launching system may include fireworks launching units which are fireworks prepared for launching, launching module units electrically connected with the fireworks launching units to ignite the fireworks launching units, a central control unit to transmit a digital launching signal programmed in advance to the launching module units, and an emergency control unit operated independently from the central control unit to independently control the launching module units. Accordingly, a launching error such as misfire during fireworks may be reduced. Since launching may be performed accurately in units of maximum 62 microseconds (?s), production technique and perfection for the fireworks displays may be increased.

    Abstract: The invention relates to a self-protection system (1) comprising at least one launching device (4) for initiating appropriate countermeasures against the threat, which comprises a sensor system (3) in the form of at least one sniper location detector or the like for detecting as well as locating a tank cover or rear cover position (6). A detection as well as a locating of the threat posed by the presence of a tank cover or rear cover position (6) ensues even before a shot is fired or before the threat. To this end, the launching device (4) is armed with pyrotechnic munitions (7), as a priority, irritation bodies or munition being integrated that, when fired, immediately produce an intense flash and/or smoke/fog (8).

  • Publication number: 20090090264
    Abstract: Pyrotechnic signaling means (10) are ignited manually by pulling on a pulling member (24). In known pyrotechnic signaling means (10), the pulling member (24) has a short cable which is knotted to an operating means (26). A knot such as this can be produced only manually, thus making the production of pyrotechnic signaling means (10) quite complex. In addition, an ignition device (14) for known pyrotechnic signaling means (10) has a hole through it for a firing bolt (36) which is connected to the pulling member (24). This allows moisture to enter the pyrotechnic signaling means (10) through the ignition device (14). The pyrotechnic signaling means (10) according to the invention provides for the pulling member (24) to be formed from flexible strip-like sections (48, 50), which are connected by film hinges (54) and can be collapsed, saving space, when not in use.

  • Publication number: 20080280264
    Abstract: A system and method for manipulating an environment to create a tactical combat scenario requires the coordinated implementation of various actions. One requires detonating an explosion simulator to create a smoke cloud with pseudo shrapnel. Another requires activating a sound enhancer, and yet another involves making a fire-ball. The combined result of these concerted actions is a perception of a single explosive event. Importantly, personnel can be within approximately one foot of any action without suffering a significant injury.

  • Publication number: 20080202371
    Abstract: A fireball generator device comprising a steel cylindrical main housing having first and second threaded end caps. A shotgun shell is encased in a barrel member and locked in place with a screw-on housing. When the shell is fired, the gases expelled by the shell push a knife blade forward into a gas container positioned within the main housing. The moving knife blade ruptures the gas container and the gas therein escapes and the powder gas from the shotgun shell ignites the gas escaping from the container creating various visual effects, such as a fireball.

  • Publication number: 20080156218
    Abstract: A pyrotechnically powered actuator having a bellows that provides a force and stroke upon initiation is disclosed. The actuator includes a housing body with a first end and a second end. The bellows is coupled to the first end of the housing body. A cover is coupled to the second end of the housing body. An initiator is located within the housing body and includes a pyrotechnic material and a bridge element. The housing body, the bellows, and the cover define a hermetically sealed chamber. The bellows is compact, lightweight, and can withstand internal and external pressure at least as high as 3,000 psi. An exemplary embodiment includes a housing body that provides a compartment for adding supplemental pyrotechnic material. Further exemplary embodiments of the actuator include a chip initiator that requires less than 1 amp to function in less than 10 milliseconds.

    Abstract: According to one embodiment, a system for simulating an actual explosion of an explosive device includes one or more firing devices and a control module. A firing device comprises a pyrotechnic device operable to direct a pyrotechnic explosion in a predetermined direction to simulate the actual explosion of the explosive device. The control module receives a trigger signal from a trigger device, which is operable to send the trigger signal in response to a trigger event. The control module detonates the firing devices in response to the trigger signal.

  • Patent number: 7154429
    Abstract: A heat seeking missile decoy device mounted on a military vehicle to change the infrared signature of the military vehicle. The device is at ambient temperature when stored on the military vehicle. When a heat seeking missile is fired at the military vehicle, the decoy device deploys and increases in temperature, changing the infrared signature of the vehicle and causing a hot spot away from vulnerable components of the vehicle. The hot spot radiates in the infrared in an area that is away from vulnerable parts of a military vehicle, drawing the heat seeking missile toward it. The termination trajectory of the heat seeking missile is at the end of the decoy device and not the vulnerable parts of the military vehicle. The energy required to heat the device is passive waste energy from the vehicle engine exhaust.

    Abstract: A binary exploding target package, a process of forming an exploding target from the contents of the binary exploding target package, and the exploding target formed therefrom. The binary exploding target package includes a first, target container and a second container. An oxidizer composition is contained within one of the containers and a catalyst composition is contained within the other container. An exploding target is formed by mixing the oxidizer and catalyst compositions, and introducing the mixture into the target container to form an exploding target just prior to using the exploding target as a target for a shooting exercise.
