Abstract: A compact transportable electromagnetic pulse (EMP) generating system for generating and transmitting EMPs at a target vehicle to disrupt electronics controlling operation of the target vehicle. The system comprises a power conditioning unit for applying a high voltage signal to a pulse generator after safety and security interlocks have been satisfied and a user actuated command received by the conditioning unit from a system control unit. The system control unit also generates a fire control trigger pulse for actuating the pulse generator and a oscillator trigger unit. After a predetermined time delay the trigger unit actuates an oscillator primed by the output of the pulse generator to transmit a series of pulses to a radiating system via an impedance matching transmission line. The radiating system radiates the EMPs having characteristics which will disable electronics in a target vehicle.

Abstract: Apparatus for monitoring an engine of a vehicle having an ignition switch operable between on and off positions, a vehicle power supply, and an electrical load, including the engine, selectively connectable to the vehicle power supply via the ignition switch. A controllable switching device is disposed between the vehicle power supply and the ignition switch. A timer accumulates time when the ignition switch is in the on position and the vehicle is stationary. If the timer reaches a predetermined time value the controllable switching device is actuated to disconnect the vehicle power supply from the ignition switch, to turn off the engine, if running, as well as disconnecting the electrical load energized via the ignition switch, limiting engine idle time, reducing engine wear and emissions, and terminating any drain on the vehicle power supply in the event the engine is not running.

Abstract: The output signal of a CMOS power-on reset circuit changes state upon detecting a predetermined threshold of the power supply voltage during the start-up transient. During the power-up of the power supply voltage, the output signal of the power-on reset circuit ramps up with the power supply voltage until the latter reaches a first predetermined level whereat a control signal begins to track the increasing power supply voltage, less two diodes potentials. Upon reaching the turn-on potential of a transistor, the control signal activates an inverter to substantially reduce the output signal signifying that the power supply voltage level is sufficient for the operation of external circuitry. The output signal then disables the current flowing through the power-on reset circuit to save power consumption.

Abstract: An erectable sawhorse including a frame and a pair of leg assemblies moveably attached to the frame, each of which can be pivoted between a collapsed position against an upper rail of the frame and an erected position away from the frame. When both legs are erected, the sawhorse can be placed upright on a supporting surface and used. Each leg is pivotally attached to the frame by a mechanism which permits the leg to be first pivoted between the upper rail and the end of the frame and second pivoted about the frame end to the erected position. A guide track attached between the upper rail and the frame end acts between the frame and the leg assembly by guiding the leg assembly through its first and second pivots.

Abstract: The flame temperature of a fluid fuel fired burner (10) is reduced by mixing flue gas (35) with the combustion air supply (34) before introduction of the fuel and combustion take place. The NOX produced by the process of combustion is thereby reduced. The flue gas (35) may also be induced from the furnace remote from the flame zone of the burner (10) such that the flame is not disturbed. A venturi (21) may be used to induce the flue gas (35) from the furnace.

Abstract: A shearing device which uses an in-line design wherein bearings are aligned with the moving blade so that lever arm forces are not produced between the movable blade and a fixed blade. This provides for highly accurate and clean cuts of printed circuit boards. The fixed lower blade is vertically oriented to provide clearance on both front and back portions for placement of tooling means to hold printed circuit boards in the shear to minimize scrap cut from the boards. Additionally, the clearance provided by the vertically oriented lower blade allows for zero space cutting of the printed circuit boards adjacent components mounted on the printed circuit boards. An optical curtain is also used which is directly aligned with the movable upper blade so that obstructions can be detected directly in the path of movement of the upper blade.

Abstract: During scribing of a ceramic plate with a laser beam, ceramic particles rise from the workpiece in a direction of motion that is generally the same as that of the workpiece. The lens on a laser scriber is protected from abrasive contact with such particulates in the atmosphere by slipping the base of a housing over the circumference of the lens mount and forming a generally airtight seal between them. The housing is shaped like a frustum of a right circular cone, with the apex end thereof truncated and essentially rolled over to form an orifice through which the lens axis and laser beam pass. A plurality of streams of pressurized air are introduced into the housing near the midpoint of the frustum and the lens surface. The air streams are introduced tangent to the inner surface of the housing and angled downward for producing a vortex of air that is exhausted to the atmosphere through the orifice at a velocity and vorticity that inhibits particulates outside of the cover entering the orifice.
