A foreign matter detection device is mounted on a non-contact power supply system that supplies power in a non-contact manner from a power supply unit to a power reception unit. The foreign matter detection device includes a magnetic field sensor and a magnetic field generation unit. The magnetic field sensor detects an amount of magnetic flux that changes due to foreign matter existing between the power supply unit and the power reception unit. The magnetic field generation unit is provided separately from the power supply unit and the power reception unit, includes a magnetic field generation coil unit, and generates a magnetic field for driving the magnetic field sensor.

A detector assembly includes scintillators configured to generate a light signal in response to an impinging backscatter signal, where the scintillators are arranged in a first pattern, a plurality of first detectors, where each first detector is coupled to a scintillator and configured to receive a first portion of a light signal from that scintillator, and where the first detectors are arranged in a second pattern aligned with the first pattern, a plurality of second detectors, where each second detector is disposed adjacent a scintillator and configured to receive a second portion of the light signal from that scintillator, and where the plurality of second detectors is arranged in a third pattern, and a scintillator collimator including a plurality of openings and configured to selectively receive the backscatter signal, where the detector assembly is configured to provide depth resolution, azimuthal resolution, a defect type, a defect size, or combinations thereof.

A detector/sensor/locator device for objects and materials of interest comprises a Faraday cage for containing or suspending a sample object or material of interest. The object or material of interest under principles of quantum theory emits electromagnetic radiation having a unique electromagnetic signature. The Faraday cage may have a cone-shape for channeling emitted electromagnetic waves upward to a barrel having mounted therein an L-shaped antenna element which may be free to rotate horizontally about the barrel or fixed in parallel with a second antenna element of similar length extending from a side of the barrel. The first and second antennae elements cooperate to detect, sense the presence of and locate a target object, the free-to-rotate antenna element capable of pointing in the direction of the target object or material. A magnetometer may be attached to an antenna element and monitored for electromagnetic field strength and/or an oscilloscope may be utilized to display signals taken from antennae coils associated with the barrel. Two magnets may be attached to the antenna elements to enhance the magnetic field. A very low frequency wave may be used to enhance (modulate) the electromagnetic wave radiation generated by the object or material of interest in comparison with a like received electromagnetic wave of unique signature of the object/material of interest.
