  • Inspection method using penetrant and dielectrometer
    Patent number: 6781387
    Abstract: Described is an inspection method for detecting defects in dielectic test materials using a penetrant material and a dielectric sensor. The penetrant material provides differing dielectric properties from test material and improves the dielectric contrast between defects substantially filled by the penetrant and the test material. The penetrant can be a liquid, such as water, or a powder, as long as it provides a substantially different complex permittivity than the test material.

  • Segmented field dielectrometer
    Publication number: 20030080744
    Abstract: A dielectrometer with a sensor face that carries an excitation electrode driven with a varying voltage. At least two sensing electrodes and a guard electrode are also carried by the sensor face. The sensing electrodes are adapted for single or multiple penetration depth measurements into a test material. The guard electrode surrounds the sensing electrodes and is at about the same voltage as the sensing electrodes.

  • Magnetometer with waveform shaping
    Patent number: 6144206
    Abstract: A detection apparatus discriminates between metallic mines and other buried objects by detecting the depth of the object, the size, the shape and the orientation of the object and the electrical properties of the object. A magnetometer sensor detects objects containing metal located below the surface of the ground. This apparatus has a plurality of parallel, spaced linear conductor sets disposed in proximity to the ground. The conductor sets have varying numbers of individual conductors. An electromagnetic field is imposed in the ground with a dominant spatial wavelength through the conductor elements. A resulting electromagnetic response of the object in the ground to the imposed magnetic field is sensed.
