摘要： An apparatus for determining the direction to and position of a buried conductor carrying an AC signal. The apparatus employs a unique antenna unit (34) having upper and lower sensors (50,52), each sensor having two orthogonal solenoid coils (54,56,58,60). The signals from these coils, which are representative of the magnetic flux therethrough, are processed to yield corresponding digital values. The numbers are combined in a novel formula to yield a value which has been empirically found to be indicative of lateral position. An appropriate display (40,74) is controlled by the microprocessor (64) according to the sign and magnitude of the positional value.

摘要： A method and system for determining the location of a first insulated conductor (10) and a plurality of similar branch conductors (28,38) that are branches of the first conductor, but without ohmic contact being made with the first conductors. A passive marker (16) having a resonant circuit that includes an inductor and capacitor is provided for each of the branch conductors and is positioned to be inductively coupled to the first conductor and the associated branch conductor. The first conductor (10) is a part of a closed loop circuit and each branch conductor is a part of separate closed loop circuits. An alternating signal (14) applied to any one of the closed loop circuits is inductively transmitted to each of the other closed loops that is inductively coupled to a passive marker having a resonant frequency equal to the frequency of the alternating signal. Flow of alternating signals in the closed loops and passive markers cause a detectable electromagnetic signal to be produced to identify the location of the first conductor, branch conductors and passive markers when conducting the alternating signals.

摘要： Method and apparatus to determine the trace and depth of metallic conductors (6) located beneath ground level. The substance of the method is that ferrite antennas (16, 16') are matched to coupled parallel oscillating circuits the capacitive element of which provides resonance frequencies equal to the (cp +- 1)-th, preferably (cp-1)-th and cp - th, or (2c +- 1)-th, preferably (2c-1)-th and 2c-th upper harmonic of the basic frequency of the alternating current, where c is a properly selected integer higher than 1, the value of p is 1, 2, 3 or 6 as required, while cp is an even number, thereafter the trace of the conductor (6) is localized by detecting the vertical component (5) of the magnetic field at an upper/lower level and the horizontal component (4) at a lower/upper level, on the basis of the ratio of the two components the trace is approximated to a certain extent, then in order to measure the depth (4) of said conductor (6) the horizontal component (4) of the magnetic field is detected both at the upper and the lower level and the depth (4) is determined by the known formula. The apparatus comprises an upper and a lower ferrite antenna (16, 16') at least one of which can be rotated in the vertical plane. By means of the method and apparatus provided by the present invention the trace and depth of conductors conducting an alternating current can be determined with a high selectivity and accuracy.

摘要： An apparatus to measure the distance to a concealed conductive object, radiating an electromagnetic signal, has two sensors, each adapted to receive the signal and to produce an output voltage proportional to the amount of signal received. Amplifier means amplify the output voltage. Automatic gain control means automatically controls the gain to the amplifier means such that the gain of the amplification of one of the output voltages is the same as the gain of the amplification of the other output voltage. Computing means calculate the distance based upon the two amplified output voltages. Display means display the calculated value.

摘要： The apparent electrical resistivities of various parts of a marine bottom (3) are determined by supplying an alternating electrical current to a pair of current supply electrodes and measuring potential differences between pairs of measuring locations. The locations are on a straight line on the marine bottom. There is a fixed ratio between the distance between the locations of each pair and the distance between said pair and the pair of current supply locations. Adjoining pairs of measuring locations have a measuring location in common. A flexible cable (1) for taking these measurements is described. The determined resistivities are subsequently compared with calculated resistivities to determine the compositions and thicknesses of the soil layers (4,5) of the marine bottom.
