摘要： A metal detector in a cover of a container, including a first winding; an inner winding with a surface area that is less than that of the first winding; and an outer winding with a surface area that is greater than that of the first winding. The inner winding is connected in series with the outer winding such that a magnetic coupling between (a) the first winding and (b) the inner and outer windings connected in series is substantially zero. Shapes, locations and numbers of turns of the inner winding and the outer winding are selected such that the metal detector is less sensitive to a metal object outside the outer winding than inside the outer winding.

摘要： An exemplary method of indicating a condition of grout within a post-tensioned tendon involves positioning a magnet and a metallic sensing plate in close proximity to an outer surface of the post-tensioned tendon; rotating the magnet and the metallic sensing plate around the outer surface of the post-tensioned tendon; measuring an amount of magnetic forces applied to the magnet during rotation of the magnet around the post-tensioned tendon; measuring an impedance between the metallic sensing plate and metallic strands within the post-tensioned tendon during rotation of the metallic sensing plate around the post-tensioned tendon; and generating an image of a cross-section of the post-tensioned tendon indicating one or more grout conditions in spatial proximity to the metallic strands within the post-tensioned tendon based on measurement data using the magnet and the metallic sensing plate.

摘要： An apparatus and a method provide an output signal indicative of a speed of rotation and/or a direction of movement of a ferromagnetic object. The sensor includes at least one magnetic field sensing element configured to generate a magnetic field signal in response to a magnetic field associated with an object. The sensor includes a detector configured to generate a detector signal having edges occurring in response to a comparison of the magnetic field signal and the threshold signal. The sensor includes an output circuit configured to generate an output signal having a first format when a characteristic of the magnetic field signal is within a first range and having a second format different than the first format when the characteristic of the magnetic field signal is within a second range, different than the first range.

摘要： Disclosed herein are a method for providing a parameter for coil design and an apparatus for the same. The method includes receiving a magnetic field parameter value for an arbitrary coil from a user; determining whether there is a constraint on each of an electrical parameter group and a geometric parameter group; when it is determined that there is a constraint on any one of the two groups, setting a parameter range for a second parameter group on which there is no constraint based on a fixed parameter set of a first parameter group on which there is a constraint; and selecting a final parameter set of the second parameter group for satisfying the magnetic field parameter value within the parameter range and outputting parameter values of the fixed parameter set and the final parameter set to the user.

摘要： Magnetic sensor system including an assembly comprising first, second, and third scalar point-sensor magnetometers being fixedly mounted with respect to one another such that the position of each magnetometer's axis is invariable with respect to the other magnetometers' axes. When the sensor assembly is in operation, each magnetometer's axis forms an angle with ambient magnetic field lines. Each magnetometer has an operating range defined with respect to a range of values of the angle formed by its axis and the ambient magnetic field. The magnetometers are positioned such that at least one of magnetometers is within its operating range at any point in time. Each magnetometer has an output signal. Computer processor determines which of the output signals is to be used any particular point in time in the sensing of local variations in the ambient magnetic field. Method of operation of the magnetic sensor system/assembly is disclosed.
