  • Publication number: 20170166921
    Abstract: Compositions and methods for controlling pests are provided. The methods involve transforming organisms with a nucleic acid sequence encoding an insecticidal protein. In particular, the nucleic acid sequences are useful for preparing plants and microorganisms that possess insecticidal activity. Thus, transformed bacteria, plants, plant cells, plant tissues and seeds are provided. Compositions are insecticidal nucleic acids and proteins of bacterial species. The sequences find use in the construction of expression vectors for subsequent transformation into organisms of interest including plants, as probes for the isolation of other homologous (or partially homologous) genes. The pesticidal proteins find use in controlling, inhibiting growth or killing Lepidopteran, Coleopteran, Dipteran, fungal, Hemipteran and nematode pest populations and for producing compositions with insecticidal activity.

  • Patent number: 8433460
    Abstract: An onboard sensor suite generally includes two main components: a proximity sensor suite for measuring the projectile muzzle velocity; and a pressure sensor suite for measuring the projectile airspeed. The flight velocity of the projectile can then be estimated with a high degree of accuracy using either the muzzle velocity by itself or the airspeed by itself, or, in a preferred embodiment, by using both the muzzle velocity and the airspeed. The proximity sensor suite includes proximity sensors that are mounted along a projectile body; a wire harness; and an onboard computer or CPU. The pressure sensor suite includes a Pitot pressure transducer and two static pressure transducers that are mounted within the projectile body; a wire harness; and a CPU.

  • Patent number: 8109213
    Abstract: A single multipurpose ammunition projectile/warhead is provided, which has the capability of clearing a variety of different types of hardened targets. The single projectile of this invention may be used for breaching steel reinforced concrete walls; may be used against light armor targets; may be used for defeating bunkers; and may also be used for antipersonnel applications. Huge savings in time, money, inventory and logistics are realized through utilizing only this one multipurpose ammunition against all these types of targets. This multipurpose projectile, among other superb capabilities, is able to puncture an eight inch double steel reinforced concrete wall timed to then have its warhead explode into fragments. This allows fragmentation in a more effective, nearly ideal direction. The projectile warhead of made of extremely thick walled 300M steel; with the projectile center of gravity to be located equidistant between a pair of bourrelets, for increased stability.

  • Publication number: 20060288448
    Abstract: Compositions and methods for protecting a plant from an insect pest are provided. Nucleic acid molecules encoding insect protoxins or insect toxins modified to comprise at least one proteolytic activation site that is sensitive to an insect gut protease are provided. Cleavage of a modified insect protoxin at the proteolytic activation site by an insect gut protease produces an active insect toxin in the gut of the insect pest. Cleavage of a modified insect toxin of the invention at a proteolytic activation site results in the production of an active insect toxin in the insect gut that displays improved pesticidal activity relative to the insect toxin that lacks the proteolytic activation site. Methods of using the modified insect protoxin and modified insect toxin nucleic acid sequences and the polypeptides they encode to protect a plant from an insect pest are provided.
