Abstract: The present invention comprises an electronic Explosive Ordnance Disposal (EOD) circuit which is desirably used with fuzed explosive weapons, such as projectiles having a nominal mission time. After expiration of the mission time, if the explosive has not detonated, the inventive circuit controls the energy supplied to the fuze detonation circuit to a level that is less than a threshold level required by the fuze for detonation, thereby preventing subsequent detonation of the explosive.

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.

Abstract: High precision, non-contact sensors are disclosed which optically measure distances from the sensor head to the surface or surfaces under test. The modular design of the system allows a large selection of identically packaged sensor heads with differing ranges and resolutions. Built-in algorithms automatically adjust exposure time and process data to maximize accuracy for most applications. The sensor heads contain a laser diode source which features visible radiation as well as infrared radiation to faciltiate set-up and use of the system. A unique optical system focuses the laser beam on a detector array. That data is processed to determine distance for point range sensors and surface profile for line range sensors. High speed algorithms are employed for reducing the data from the imaging array in the sensor head to meaningful range data. To compensate for widely varying surfaces of the software can vary the exposure and laser power to yield a dynamic range of 10.sup.7.

Abstract: A laser based optically triggered sensor system is described which can function as a coordinate measuring machine (CMM) probe. With the sensor, a CMM can find the exact location of the surface of a test object without physically having to touch the object. The reflectivity of the laser beam is sensed by a detector pair. The ratio of light on the detector pair is sensed and used to indicate when the probe is in range for a measurement, out of range for the measurement, and when in range, whether the object being sensed is too far or too close from the trigger point of the probe. The system is a plug compatible replacement for existing contact trigger probes currently used on most CMM's.
