Abstract: A ballistic optical camera trigger having an integrated circuit capable of onverting light to a proportional frequency, wherein the integrated circuit has a fast response time and a wide dynamic range which allows it to sense positive or negative changes in light fast enough to trigger without delay for high speed imaging without computational delays or jitter causing interference. The frequency output of the integrated circuit is tracked by a phase lock loop/voltage controlled oscillator to allow it to follow slow changes in light, but not fast changes in light caused by, for example, a projectile such as a bullet. The frequency output from the integrated circuit is provided to one input of a logic gate which receives at another input thereof, a shaped pulse from the phase lock loop/voltage controlled oscillator circuit, wherein the output of the logic gate is applied to a one-shot for outputting a trigger signal.

A bubble level is provided for vertical alignment of the mast.

Abstract: A method is provided for dispersing and/or disrupting an aligned jet from a haped charge round. A fluted shaped charge liner, typically used to compensate for spin effects on a coherent jet in a spin stabilized round is applied to a non-spinning round to produce a dispersed and/or disrupted jet pattern. The effect of disruption may also be altered by altering the subcalibration ratio (ratio of liner diameter to charge diameter). For a given liner diameter, an increase in charge diameter may result in increased dispersion of the jet. In addition, other types of spin compensated liners such as those using so-called metallurgical spin compensation, may be applied to a non-spinning round to produce dispersion and/or disruption of the jet. Moreover, the rate of spinning of the round (or the direction of spin) may be altered such that the spin compensated liner produces a dispersed jet pattern.

Abstract: A fire suppression system for a dumb waiter for carrying hazardous materi in a multiple story building includes an exhaust at the top of the shaft, a storage compartment for carbon dioxide gas above the topmost floor served by the dumb waiter, a first nozzle in the shaft near the top thereof, a second nozzle in the shaft near the bottom thereof, and conduits interconnecting the storage compartment and the nozzles. The system further includes vapor detectors in the shaft, each of which is adapted, upon detection of unsafe vapors in the shaft, to open the conduits to flow the carbon dioxide gas from the storage compartment to the nozzles and thence into the shaft above and below the dumb waiter, and to shut down operation of the exhaust.

Abstract: The jet of a shaped charge ammunition round may be disrupted and dispersed y altering the local charge to mass ratio within the shaped charge round. A shaped charge round typically produces a coherent jet suitable for penetrating thick armor or the like. However, such coherent jets may be unsuitable for damaging thinner targets. By placing a mass (or removing a mass) at a local portion of the shaped charge liner, the outer casing, or the explosive charge, the local charge to mass ratio may be altered, causing disruption of the coherent jet. A wire, wrapped around the charge liner in a spiral fashion, may be used to produce a substantially helical or spiral shaped jet which may be particularly applicable for damaging missiles or the like.

Abstract: A device for assessing an impact of a projectile with a target using optical radiation from the flash of the impact. The invention includes an optical radiation detector, which detects optical radiation from the impact flash using optical, electronic and optoelectronic devices. The optical radiation detector is situated on a tank firing the projectile at a target. Further included is an optical radiation augmenter, which is a pyrotechnic material, mountable on a projectile, for augmenting the flash of the projectile impact with the target. By analyzing the signatures of pyrotechnic materials using the optical radiation detector, one can easily identify which projectile impacted the target, determine a distance traveled by the projectile, and assess the projectile impact by ascertaining whether the projectile perforated the target.

Abstract: A digital sensor network scanner for use in monitoring resin flow and its re progress during a resin fabrication process in which a plurality of non-intersecting electrically conductive threads are arranged in a grid-like configuration with each sensor thread having a sensor input for a sensor data path so as to create a plurality of sensors is disclosed in which a first section of the scanner supplies time encoded pulses to the sensor input path. A second section of the sensor network scanner includes a plurality of detectors which are connected to the sensor data path as well as to a plurality of LEDs and which are also triggered by the same time encoded pulses applied to the sensor input path. When a sensor data path is in a conducting state, the applied time encoded pulses propagate down the sensor data path to the detector which, having simultaneously received a signal from both the network scanner and the sensor, illuminates the LED.

Abstract: A fully polarimetric broadband antenna for emitting and receiving non-dissive EMP signals has dipole elements orthogonally mounted on a ground plane which tilts the elements relative to the direction of wave propagation. The ground plane can be shaped into either a pyramid or cone, and the elements may be truncated cones or substantially discus-shaped. A single-pole-single-throw reed relay is mounted between dipole elements which are independently driven to provide horizontal and vertical polarizations. The antenna provides a response and pattern suitable for transmitting short EMP signals useful in radar and communications applications.

Abstract: A solder composition and method of soldering using composite solders comprising a solder alloy and intermetallic filler particles. The intermetallic filler particles are lead-free, have high strength, wet and disperse well in solder joints, remain uniformly distributed and resist degradation on long-term aging. When added to commercial bulk or paste solders, the intermetallic particles reduce the lead content of solder joints by consuming volume in lead-tin solder, and improve the mechanical properties of the solder by inhibiting localized shear deformation and interfering with crack growth.

Abstract: A movement and sound monitor and stimulator which is particularly useful for preventing death in human infants from sudden infant death syndrome is disclosed. The movement and sound monitor and stimulator has a base member which may be a fluid-filled sensing pad for supporting the infant or other animate object which is being monitored and a transducer positioned for detecting movement or acoustic activity (e.g., heartbeat, breathing) of the object on the base member to provide an output signal in response to forces applied thereto which are generated by such movement. A circuit is connected to monitor the output signal from the transducer and activates a stimulator which is operable to provide movement to the base member to stimulate movement in the object when output from the transducer to the circuit corresponds to no movement from the object. The transducer may be a pressure transducer in fluid communication with the fluid interior of the sensing pad.
