  • Magnet position sensing system
    Patent number: 4422041
    Abstract: Magnetic position sensing for an object is disclosed wherein the analogue the distance between an object and a sensor is detected for indicating changes in object position in one, two, or three dimensions. An accurate, and continous output signal indicative of object position and incremental changes in that position are obtained. Additionally, magnetic sensing provides motion sensing of a support structure or velocity and acceleration sensing of an object.

  • Capacitive discharge firing mechanism
    Patent number: 4095508
    Abstract: A capacitive discharge firing mechanism for a lightweight portable rocket uncher in which the capacitive discharge firing mechanism includes means for interconnecting electrical circuits for supplying an electrical pulse to a rocket carried in the launcher for ignition of the rocket motor. The means for interconnecting electrical circuits includes three safety type means which prevent accidental actuation of the firing button for the electrical circuit.

  • Rear gate peep sight device
    Patent number: 4092899
    Abstract: A rear gate peep sight device built into discharge firing mechanism for a ghtweight portable rocket launcher by incorporating a rear peep into a cover for the firing mechanism. The rear peep is used with a front reticle mounted at one end of the rocket launch to aim or align the rocket launcher with a target. The cover is mounted to the firing mechanism and folds down to cover the firing mechanism safety and firing button.

  • Thermal battery firing mechanism
    Patent number: 4091710
    Abstract: A thermal battery firing mechanism for a lightweight portable rocket launr in which the thermal battery firing mechanism includes means for actuating a thermal battery for supplying an electrical pulse to a rocket carried in the launcher for ignition of the rocket motor. The means for actuating the thermal battery includes three safety type means which prevent accidental actuation of the firing button for the thermal battery.
