  • Inertial delay fuse
    Patent number: 8584585
    Abstract: An inertial delay mechanism for use in an explosive projectile is provided. The delay mechanism consists of an inertial delay fuse that is precise, doesn't require sensitive primary explosives and doesn't utilize electronic circuitry. The inertial delay fuse includes a free sliding charge element that strikes an anvil located opposite to the sliding charge element. A delay gap is provided between the sliding charge element and the anvil. Upon impact, the sliding charge element slides forward and impacts the anvil, thereby inducing a shock wave in an initiator charge that subsequently results in detonation of main charges. The design is mechanically simple and robust enough to withstand severe g-loading forces that occur during firing and penetration of a projectile.

  • Method and apparatus for determining locations of a moving radar
    Patent number: 8587467
    Abstract: A method for determining locations of a moving emitter is disclosed. Initially, a set of emitter pulses is collected when a collector platform moves over a collection baseline. In addition, the time and location of the collection platform are recorded each time an emitter pulse is collected. A set of time-tagged pulse time-of-arrival (TOA) values is then generated by associating a recorded collection time value to each of the collected emitter pulses. Next, a set of time-tagged and position-tagged pulse TOA values is generated by associating a recorded collection location value to each of the time-tagged pulse TOA values. Finally, a set of location values and velocity values of a moving emitter is estimated based on the time-tagged and position-tagged pulse TOA values.
