摘要： A metal detector 20 includes a detection signal acquisition unit 31, a threshold value setting and updating unit 32, and a determination unit 33. The detection signal acquisition unit 31 acquires a detection signal that changes according to the detection strength for a rebar W1 contained in concrete W, on the surface of the concrete W. The threshold value setting and updating unit 32 sets a threshold value in order to determine the presence or absence of the rebar W1 on the basis of the maximum value and/or the minimum value included in the acquisition results for the detection signal acquired by the detection signal acquisition unit 31. The determination unit 33 determines the presence or absence of the rebar W1 by using the threshold value set in the threshold value setting and updating unit 32.

摘要： A solution for evaluating a medium using electrical signals is described. A plurality of electrical signals having different frequencies are transmitted through the medium and signal data corresponding to the electrical signals after having traveled through the medium is acquired. A complex impedance and a complex permittivity and/or complex conductivity can be calculated for the medium. A set of characteristics of the medium can be computed using mixing models and/or known information of the medium. A level of one or more attributes of the medium can be determined from the characteristics using nonparametric Bayesian inference. One particular application is directed to determining a nitrate level of soil.

摘要： It may be difficult to determine the location of objects underwater, especially when they are buried below a seabed. A system for detecting conductive objects underwater may include a long conductive cable in electric communication with a signal generator. When the cable is positioned proximate to the conductive object, its signal may induce a current and a detectible secondary magnetic field in the conductive object. A sensor, preferably positioned distally from any portion of the conductive cable, may detect the secondary magnetic field and thereby determine the location of the conductive object. A method of detecting and mapping the location of a buried underwater pipeline comprising a conductive material may include: sending a predetermined current through a conductive cable attached to a first water vehicle; inducing an induced current in the pipeline; and detecting the location of at least a portion of the pipeline by a sensor attached to a second water vehicle.
