  • Patent number: 6061035
    Abstract: A frequency-scanned end-fire phased-array antenna includes a board, a sinuous transmission line formed on the board, a plurality of end-fire antennas, and a plurality of couplers corresponding to the end-fire antennas, such that the transmission line is selectively coupled to the plurality of end-fire antennas via the plurality of couplers, for selectively coupling energy within the transmission line to the end-fire antennas. By varying the input frequency to the antenna over a narrow range, the direction of a main radiation beam emitted by the antenna can be scanned .+-.90 degrees from broadside. A single antenna board produces a frequency-scanned fan beam. Stacked antenna boards can produce a frequency-scanned pencil beam, or several independent frequency-scanned fan beams at different frequencies. The present antenna can operate in the microwave, millimeter-wave, terahertz, infrared, or optical frequency range.

  • Patent number: 6050195
    Abstract: A fuze self-neutralizing system is used for munitions having fuzes with sng-forced sliders (13) and stab detonators (19). The self-neutralizing components include an auxiliary battery (5), a auxiliary timing circuit (3) and a physical barrier (11) that prevents the firing pin (18) from contacting the stab detonator (19). Once the barrier (1) is in place, the munition can be handled with relative safety.

  • Patent number: 5956604
    Abstract: A partially ionized beam (PIB) deposition technique is used to heteroepitally deposit a thin film of CoGe.sub.2 (001) on GaAs (100) substrates 14. The resulting epitaxial arrangement is CoGe.sub.2 (001) GaAs (100). The best epitaxial layer is obtained with an ion energy 1100 eV to 1200 eV and with a substrate temperature of approximately 280.degree. Centigrade. The substrate wafers are treated only by immersion in HF:H.sub.2 O 1:10 immediately prior to deposition of the epitaxial layer. Contacts grown at these optimal conditions display ohmic behavior, while contacts grown at higher or lower substrate temperatures exhibit rectifying behavior. Epitaxial formation of a high melting point, low resistivity cobalt germanide phase results in the formation of a stable contact to n-GaAs.

  • Patent number: 5932834
    Abstract: The Auto-destruct fuze is a mechanism that provides a primary mode detona and a delayed auto-destruct/self-neutralize mode detonator function for a grenade or similar munition. The mechanics for the primary mode detonation is similar to the M223 fuze which the present invention is designed to replace. Operation of the auto-destruct/self-neutralize mode is based on the working principles of the Liquid Annular Orifice Device (LAOD). The LAOD is released from a locked position upon expulsion of the device from a storage container. The LAOD moves slowly under the urging of a spring and eventually releases a cleanup firing pin which activates a cleanup detonator to auto-destruct or self-neutralize the grenade.

  • Patent number: 5924799
    Abstract: A segmented pilot ball is assembled within a spherical bearing for procesg a self lubricating liner. The two-part pilot ball includes a major annularly shaped hollow segment with a smaller cutout portion. A minor segment has the shape of the cutout portion so that when the major and minor segments are assembled, the minor segment complements the major segment to define the spherical outer shape of the pilot ball. An inner plug is shaped to fit within the assembled major and minor segments to provide a compressive force and interior support to the pilot ball within the outer race of the bearing. The bearing is formed by applying uncured liner material to the inner surface of the outer race either before or while rotating the outer race, to evenly distribute the liner and to increase the rate of drying. The outer race is then rotated while heating, in order to reduce liner flow and to form a uniform coating.

  • Patent number: 5879309
    Abstract: A motion detection device for monitoring patient movement. The device includes a sensor adapted to generate a voltage from mechanical vibrations and a circuit in operable relationship with the voltage for generating an alarm upon detection of a predetermined signal. The circuit provides a fixed impedance to the sensor. A micro controller is used for analyzing the signal to select from first and second conditions by sensing activity within sequences of preselected time intervals. The first condition represents a medical condition and the second condition represents casual motion. A switch is used for setting a time interval and a total sampling time for the micro controller. An alarm signal generates an alarm upon detection by the microprocessor of a predetermined activity. The preferred sensor comprises a housing having an outer shell and a hollow spherical opening therein.

  • Patent number: 5874691
    Abstract: A collapsible training projectile includes a nose, a body and a tail. The dy has a forwardmost end secured to the nose, and a rearwardmost end secured to the tail. The body further includes one or more axial, longitudinal slots that extend radially through at least part of the body, such that when the projectile impacts with an object, the kinetic energy causes the body to plastically deform along the slots, thereby reducing the penetration energy of the projectile. In another embodiment, the projectile includes a wedge, a body and a tail. The forwardmost end of the body is secured to the wedge, and its rearwardmost end is secured to the tail.

  • Patent number: 5802755
    Abstract: A device that locks a threaded collar around a cylindrical gun barrel has a lunger extending in a radial direction through the collar. The plunger rides upon a series of ratchet teeth, disposed around the circumference of the gun barrel. The ratchet teeth include ramps and steps. As the collar is threaded onto the gun barrel, the plunger rides up the ramp of each ratchet tooth and drops into the step of the next ratchet tooth around the gun barrel. When in place, the plunger is pushed backwards against the wall of the ratchet tooth and arrests rotation of the collar in the unthreading direction. To remove the collar, the plunger is lifted clear of the ratchet tooth. With the plunger held clear of the step of the ratchet tooth, the threaded collar can be unthreaded.
