Electrical impedance tomography (EIT) is a technology developed to image the electrical conductivity distribution of a conductive medium. The technology is of interest because of its low cost and also because the measurement of the electrical conductivity brings direct information about the composition of the conductive medium. Because the ground is conductive to a certain extent, the technolog...
Optical magnetometers measure magnetic fields with extremely high precision and without cryogenics. However, at geomagnetic fields, important for applications from landmine removal to archaeology, they suffer from nonlinear Zeeman splitting, leading to systematic dependence on sensor orientation. We present experimental results on a method of eliminating this systematic error, using the hexadec...
This paper presents a new approach to the detection of anti-personnel landmines which is based on the physical detection of landmines using a sharpened probe in a fashion similar to that employed by human deminers. The axial force applied to the probe is sensed as the probe is driven into the ground (at 30 degrees to the horizontal in order to avoid initiating the landmine), and the force infor...
Physical factors When 16 years old, he was knocked out in a landmine explosion. Both arms were fractured and he had abdominal and chest injuries. At 21 years he suffered from pulmonary tuberculosis. He was treated with a phrenic nerve crush and with surgical pneumothoraces which were corrected in 1949. He has since suffered from chronic bronchitis each winter. Physical examination revealed the ...
