摘要： Digital logic comprising a high speed analog to digital converter, a high speed analog to digital converter, a digital multiplier, and an infinite impulse response filter and decimation circuit are used to digitize a magnetic signal that is subsequently processed by magnetic data processing algorithms. The high resolution digital to analog converter is directly incorporated in a feedback loop of a magnetometer sensor, and an expensive precision analog to digital converter is replaced by a less expensive, lower power digital to analog converter. The improvement provided by the present invention includes a high speed analog to digital converter coupled between the oscillator and a first input of a multiplier, and a second analog to digital converter that is coupled between the sense coil of the sensor and a second input of the multiplier. The output of the multiplier is coupled to an infinite impulse response filter and decimation circuit that produces the digital output signal from the magnetometer. The output of the infinite impulse response filter and decimation circuit is coupled by way of a digital to analog converter to the feedback coil of the sensor. Depending on the system requirements, the two analog to digital converters, the digital multiplier, and the infinite impulse response filter and decimation circuit may be implemented in one readily available microcontroller at low cost. This serves to reduce the number of components, complexity, and expense of the magnetometer.

摘要： A system for passively sensing low frequency (5 Hz to 50 kHz) EM emanations from vehicles and classifying them on that basis. A temporal frequency response is computed for the sensed EM emanations. Harmonic, non-harmonic and temporal features are extracted from the response and used to classify the vehicle. In the preferred embodiment, the temporal frequency response is displayed as a time, frequency and intensity plot, from which a technician visually extracts these features. The features can then be used either to determine a "signature" for classifying the vehicle or to determine specific characteristics which, in turn, can be used to classify the vehicle. Alternately, the feature extraction and classification can be performed by an automated classifier.

摘要： Digital logic and a high resolution digital to analog converter are used to adequately digitize a magnetic signal that is subsequently processed by magnetic data processing algorithms. The high resolution digital to analog converter is directly incorporated in a feedback loop of a magnetometer sensor, an expensive precision analog to digital converter is replaced by a less expensive, lower power digital to analog converter. The circuit improvement provided by the present invention includes an analog low pass filter coupled to the sensor, a digital logic circuit coupled to the analog low pass filter for providing an output signal from the magnetometer and a feedback output signal, and the digital to analog converter coupled between the digital logic circuit and a feedback coil of the sensor for coupling the feedback output signal thereto. The digital logic circuit includes an analog to digital converter, an adder having a first input coupled to the analog to digital converter, and an accumulator coupled between an output of the adder and a second input of the adder. The digital logic circuitry processes the error signal from the analog multiplier, eliminates high frequency components, and digitizes the result. Thus, a low resolution analog to digital converter, having a resolution of only a few bits, may be used.

摘要： Processing methods and apparatus that process magnetometer data derived from an array of magnetometer sensors and outputs both the position and velocity of a magnetic dipole. In the method and apparatus, (a) a set of actual magnetic field measurements of a magnetic dipole is collected using the array of magnetic sensors. Then (b), a trajectory for the magnetic dipole is hypothesized. Then (c), a set of estimated magnetic field measurements is determined that would be formed by a magnetic dipole moving along the hypothesized trajectory. Then (d), the actual magnetic field measurements are compared with the estimated magnetic field measurements. Then (e), based on the comparison, a new trajectory for the magnetic dipole is hypothesized. Steps (c) through (e) are repeated until agreement between the actual magnetic field measurements and the estimated magnetic field measurements is deemed sufficiently close. The trajectory is displayed for viewing on a display.

摘要： A fault tolerant integrated circuit employs triple redundant storage of data and continuous voting to protect the data from Single Event Upset, or SEU. The integrated circuit includes three or more registers and a majority voter. The three registers are connected in series to each other with the output of the first register being connected to the input of the second register and the output of the second register being connected to the input of the third register. The majority voter is connected to the output of each register and generates a signal corresponding to the majority of all of the register outputs. The output of the majority voter is connected to the input of the first register, thereby correcting any incorrect data stored in the registers.

摘要： Self leveling apparatus that includes a frame, a device that is to be leveled, and a leveling mechanism such as a double ring gimbal having an inner gimbal ring and an outer gimbal ring. The outer gimbal ring is secured to the frame and the inner gimbal ring is secured to the device and to the outer ring. The inner ring comprises a viscous or preloaded bearing that allows the device to swing around an inner ring axle to thereby level itself in that axis and prevent spurious movement of the device. The outer gimbal ring and inner gimbal ring are attached by outer axles that comprise a viscous or preloaded bearing that allow the inner gimbal ring to swing around the outer axles thereby level the inner gimbal ring in that axis and prevent spurious movement of the device. A disclosed embodiment of the invention includes a magnetometer sensor that is coupled to signal processing and telemetry electronics and a power source that are leveled to keep axes of the sensor oriented along horizontal and vertical axes.

摘要： An apparatus for testing hybrid substrates having a large number of networks and pads. The apparatus includes a DC power supply and a vacuum chamber. The vacuum chamber is equipped with a hot-filament electron source, and this electron source is electrically connected to the negative terminal of the DC power supply. The vacuum chamber is also equipped with a movable probe for making electrical connections from the positive terminal of the DC power supply to any one of the pads on the substrate. A small amount of phosphor of a type that glows when bombarded by electrons is placed on each pad of the substrate to be tested. The substrate is placed in the vacuum chamber for testing. The probe is brought into contact with one of the pads on the substrate, and a voltage in the order of 100 volts is applied between the electron source and the probe. Pads that are electrically connected to the probed pad act as anodes, thus attracting the electrons from the electron source, and are identified visually by the glow of the phosphor.
