  • Publication number: 20060283317
    Abstract: A projectile tracking system for acquiring and precisely tracking a projectile in flight in order to reveal the source from which the projectile was fired. The source is revealed by the back projection of a 3-dimensional track file. In preferred embodiments the system is installed on a vehicle, such as an un-manned blimp or other aircraft, road vehicle or ship, for locating and destroying small arms fire directed at the vehicle. A kill system may also be included on the vehicle to destroy the source of the projectile.

  • Patent number: 5796474
    Abstract: The present invention provides a projectile tracking system for acquiring and precisely tracking a projectile in flight in order to reveal the source from which the projectile was fired. The source is revealed by the back projection of a 3-dimensional track file. The system is particularly suited for tracking a bullet fired by a sniper and identifying the location of the sniper. Projectiles of interest are typically traveling at a substantial fraction of the speed of sound or even faster than the speed of sound and therefore become hot due to aerodynamic heating. A telescope focuses infrared light from a relatively large field of view on to an infrared focal plane array. In a projectile detection mode, the system searches for the infrared signature of the fast moving projectile. The telescope's field of view is steered in the azimuth by a step and stare mirror which is driven by an azimuth drive motor mounted on the frame.

  • Patent number: 4633103
    Abstract: A laser method of and apparatus for providing a wide variety of laser wavelenghts wherein a pump source of laser radiation is sequentially Strokes-shifted in two separate cells each containing a different molecular or atomic Raman active gas, wherein each cell is optimized to produce primarily first-Stokes radiation as by variation of focal length parameters and/or gas pressure, filter means are provided at the output of the first cell to reject the pump laser radiation and to pass the first-Strokes radiation of the first cell and further filter means are provided at the output of the second cell to reject the first-Stokes radiation of the first cell and pass the first-Stokes radiation of the second cell to provide a desired output laser radiation.

  • Patent number: 4229708
    Abstract: This invention is directed towards a scalable X-ray laser comprising means for providing an active medium of lithium-like atoms or ions, means for producing in the active medium a population of low density ions in an excited intermediate metastable state and a visible or near infrared laser to stimulate X-ray lasing by resonant or non-resonant antistokes Raman process to the ground state of the ions. The irradiation of the ions by the laser provides phased or traveling wave excitation which produces the desired directivity. Production of the metastable state is provided by directing energy from a suitable source, such as a high power short pulse laser beam, onto a target material and causing it to radiate as a black body, filtering this radiation to derive radiation in the soft X-ray region, and directing this filtered radiation into the lithium-like vapor.

  • Patent number: 4074277
    Abstract: An ink jet synchronization scheme, wherein the drop formation of respective streams in an ink jet array are synchronized acoustically by individual acoustic fiber inputs to each of the streams. The acoustic fibers are attached to grooves adjacent each of the nozzles, with acoustic isolation being provided between the fiber and the nozzle substrate to prevent direct excitation of the substrate. This prevents the occurrence of resonance within the nozzle plate. Alternatively, acoustic isolation is achieved by mounting the synchronization structure separate from the nozzle plate. For example, the acoustic fibers are attached to the charge electrode structure, or are attached to a support structure intermediate the nozzle plate and the charge electrode structure. The acoustic energy inputs to the fibers are independently controlled as is required for certain printing schemes or are made identical as is normally the case.

  • Patent number: 4047183
    Abstract: Method and apparatus is described for controlling the formation and shape droplets in an ink jet stream. The continuous portion of the stream is illuminated with a radiant energy source such as a laser. The surface wave profile produced by illuminating the stream is sensed to provide the fundamental and harmonic frequency components thereof. A perturbation drive signal, the amplitude and relative phase of which is a function of the sensed frequency components, is provided for controlling the formation and shape of the droplets.

  • Patent number: 4014029
    Abstract: A jet printer includes a nozzle plate having at least two rows of nozzles, with the nozzles in one row being laterally staggered with respect to the nozzles in another row. The jets emanating from the respective rows of nozzles are directed in non-parallel trajectories to form at least a portion of a single line of dots at a time on a printing medium, with the jets from a given row forming non-adjacent dots on the printing medium. In practice, the nozzle plate is comprised of a semiconductor substrate, for example silicon, with the exit aperture of each of the nozzles in at least one row being axially misaligned with respect to the longitudinal center axis of their respective entrance apertures, resulting in a non-normal jet trajectory with respect to the plane of the nozzle plate.
