Abstract: A laser tracking processor is provided for integrating measured target-reflection signals used in directional control. The integration is performed to distinguish pulses reflected from the target against a noise background. The processor includes an optical detector, an accumulator, a correlator, a phase-lock loop and an integrator array. The optical detector receives the measured signals distributed among several guidance channels. The accumulator sums the measured signals as a combined signal for all the channels. The correlator temporally identifies an event that occurs to indicate a target-reflection pulse within the combined signal. The phase-lock loop synchronizes the event with a clock reference to produce a pulse window within which to search the combined signal for the pulses. The integrator array superimposes the measured signals within the pulse window for each channel to produce channel-specific integrated pulse signals.

Abstract: A switch circuit is provided for conditional communication within a magnetic-induction interface, including first and second control nodes, a data input and output nodes, a parallel circuit, and first and second control nodes. The parallel circuit includes a pair of legs, each leg connecting to the data input and data output nodes. Each leg has a connector to a condition. Each control node is connected to the corresponding connector. The condition is one of the interface is connected and the interface is disconnected. The parallel circuit enables communication between the data input and output nodes only in response to the condition being that the interface is disconnected. The pair of leg includes first and second legs. The first leg includes a first MOSFET and a first diode. The first MOSFET has a first source, a first gate and a first drain. The second leg includes a second MOSFET and a second diode. The second MOSFET has a second source, a second gate and a second drain.

Abstract: A firing circuit that is used for a lightweight launcher for propelling rets is disclosed. The firing circuit generates a pulse for firing the rocket launcher and comprises first and second capacitor banks. The first capacitor bank acts as low impedance energy source, in which power is developed to supply sufficient energy to initiate the rocket motor squib which, in turn, ignites the rocket motor of the rocket. The second capacitor bank acts as a high voltage, low impedance source whose energy is used to charge a capacitor internal to the rocket. The capacitor internal to the rocket, is part of the rocket warhead fuse. The capacitor internal to the fuse is used to initiate the detonator of the rocket warhead when the rocket terminates flight at target.
