  • Patent number: 6967614
    Abstract: A projectile launch detection system utilizes a continuous wave radio frequency signal (CW/RF) to confirm muzzle exit. The projectile launch detection system can be used in smoothbore, fin-stabilized, non-air breathing projectiles. The gun tube appears as a waveguide to the projectile launch detection system during projectile launch. The projectile launch detection system transmits a CW/RF signal down the gun tube during launch of the projectile. A portion of the CW/RF signal is reflected back by an impedance mismatch at the boundary between the muzzle of the gun tube and free space. Upon exit by the projectile from the gun tube, an exit signature is detected that is defined by the impedance of the gun tube and by a ratio of the diameter of the gun tube to the frequency of the CW/RF signal. The projectile launch detection system processes the exit signature to detect a muzzle launch of the projectile from a specific gun tube.

    Abstract: A power indicating setter system monitors the power level of a fuze setter coil of a fuze setter system for a gun operable to fire inductively-fuzed shells. The fuze setter system transmits a carrier signal that induces magnetic field power in the fuze setter coil. The strength of the magnetic field power correlates to reliability of the fuze setter system to transmit fuzing data to the shells. The fuze setter coil induces a signal in an adjacent induction element. Circuitry, coupled to the induction element, operates to compare the signal to a calibrated signal produced by the circuitry. The circuitry, by a power indicator, functions to indicate to an operator when the value of the signal is greater than the calibrated value. The power indicator indicates during operation of the gun, thereby informing the operator of the reliability of the fuze setter system to transmit fuzing data to the shells.

  • Patent number: 6176168
    Abstract: Improved transmitter coil, improved fuze setter circuitry for adaptively tuning the fuze setter circuit for resonance and current difference circuitry for interpreting a fuze talkback message. The transmitter coil utilizes an “L” shaped coil cross section, with the wrapped coil portion being at right angles to the return coil portion, in order to increase the coupling efficiency between the fuze setter coil and the fuze receiver coil, as compared to the prior art “C” coil. The inventive “L” shaped cross section also eliminates counter magnetic field due to the return coil portion being at right angles to the wrapped coil portion. The fuze setter includes circuitry for adaptively tuning the resonant LC circuit for resonance by adjusting the capacitance in the LC circuit to maximize current in the LC circuit. The fuze setter utilizes a switched capacitor network circuit to tune the LC circuit for resonance.

  • Patent number: 6170377
    Abstract: A method for contactless inductive transmission of programming data to a programmable time fuse included in a shell for a single shot, semi-automatic, or fully automatic shell firing barrel weapon. While the shell is situated in a cartridge chamber of a barrel of the weapon, data is transmitted to the programmable time fuse from a programming device of the weapon via a transmitting coil arranged around the cartridge chamber of the barrel to a receiving coil arranged in the shell. At least a part of the barrel lying between the coils is replaced by a non-magnetic material and designed so that it does not form an electrically conductive short circuited layer that would prevent transmission between the coils.

  • Patent number: 5078051
    Abstract: An improved ammunition data transmission system includes alternately applied parallel sources of high frequency of alternating current (AC) voltage and direct current (DC) voltage. The high frequency AC voltage is applied first to provide updated data and to activate the electronic control package for the round in the projectile. the DC voltage then activates the electric primer system for igniting the propellant charge to fire the round. Both the electronics control package and the electric primer system are connected in parallel with the source of AC voltage and, in the preferred embodiment, the parallel connected circuitry contains a capacitor to prevent DC voltage from reaching the electronics control package and an inductor for preventing AC voltage from reaching the electric primer system.

  • Patent number: 5050574
    Abstract: A baseball pitching machine including a metal cart that rides on a plastic elliptical track wherein the metal cart carries a baseball and is controlled by a series of switches that command a rectangular-shaped electromagnet mounted on the plastic track and having an opening. The electromagnet is turned on via a switch and the metal car accelerates toward the electromagnet till it engages a projection mounted on the track which turns off the electromagnet. The momentum gained by the cart then carries the cart to a curve of the elliptical track where the baseball is projected as the cart goes around the curve of the track. After the cart protects the ball the metal cart proceeds along the track to the starting point where the cart is ready to reload with another baseball and the operation starts over with the switching on of the electromagnet.

  • Patent number: 5014591
    Abstract: A time delay mechanism force fuze wherein the mechanism comprising an encoder ring, having an inner surface with a predetermined mask pattern of lands and grooves, is locked by a spring lock exerting pressure in a radially outward motion, thus enhanced when the fuze is exposed to the influence of dynamic forces from a gun, is shown. The spring lock cooperates with a lock pin such that a radially inward deflection of the lock pin deflects the spring lock so that the encoder ring with a reaction surface is unlocked and can be fully rotated by a setting collar acting through a detent spring on the reaction surface. If the encoder ring is locked, the detent spring is deflected over the reaction surface of the encoder ring when the setting collar is rotated, thereby preventing the encoder ring from being changed. A plurality of actuators, which determines a digital word that represents a length of time for a time delay in a digital timing circuit for the fuze, is actuated by the predetermined mask pattern.
