  • Patent number: 11536551
    Abstract: A laser ignition assembly comprises first and second mounting surfaces opposed to each other. A central cavity is formed through the surfaces and sized to receive energetic material therein. A vertical solder bridge is formed between the surfaces and an edge emitting laser diode disposed between the surfaces. The laser diode is oriented such that a light fluence therefrom is directed in a radial direction into the central cavity. The surfaces can be circuit boards, e.g., copper clad, rigid circuit boards, and have an annular shape. The central cavity can be further defined by an interboard gap between the surfaces. The ignition assembly can fit within a primer cup of a munition.

  • Patent number: 10859358
    Abstract: An ignition system for energetics including artillery charges includes a radio frequency transmitter and a radio frequency igniter. The radio frequency igniter receives and converts radio frequency energy into heat or electrical energy for the purpose of igniting energetics, such as propellants or pyrotechnics. The radio frequency igniter may be applied to the exterior of the energetic container or may be integral to the container.

  • Patent number: 10627200
    Abstract: An ammunition cartridge for a gun is optically initiated by a mechanism wholly within the cartridge case itself. The case has as optical primer initiation means producing light fluence to ignite an optical sensitive mix, which ignited optical sensitive mix may in turn ignite into a flashtube, and which ignited flashtube may in turn ignite a bed of propellant in said cartridge. The optical primer initiation means may be an LED, a laser diode, a VCSEL, or some other light emitting device in general. The cartridge optically initiated primer package is so sized and made electrically and mechanically seamlessly physically compatible with current ammunition cartridges such that these new cartridges are completely interchangeable.

  • Patent number: 10107607
    Abstract: An ignition system for energetics including artillery charges includes a radio frequency transmitter and a radio frequency igniter. The radio frequency ignitor receives and converts radio frequency energy into heat or electrical energy for the purpose of igniting energetics, such as propellants or pyrotechnics. The radio frequency igniter may be applied to the exterior of the energetic container or may be integral to the container.

  • Publication number: 20130291755
    Abstract: A visible or invisible light-producing device in an inert target practice projectile creates visible and/or infrared light initiated by a deceleration sensitive triggering element when the projectile impacts a target. A visible signature is creating for recording the impact to provide training without the use of any pyrotechinc, or other hazardous materials being deposited on the impact area. The light producing device may be initiated by fuze electronics—prior to actual impact—to facilitate simulating an airburst projectile for training or testing purposes.
