  • Patent number: 11131695
    Abstract: The present disclosure is concerned with measuring the amount of electrical energy consumed even when the electric meter has been tampered with. Electric meters may be fraudulently tampered with by connecting a bypass element, such as a conductive wire or cable, across the terminals of the meter in order to bypass the electric meter. This means that only part of the consumed electrical current passes through the electric meter for measurement, resulting in some of the consumed electrical energy not being measured and therefore not being billed for. However, in the present invention a technique has been developed to enable the electric meter to determine the amount of electrical current that bypasses the meter and therefore measure the amount electrical energy consumed even when the electric meter has been tampered with.

An external magnetic field and a bias magnetic field supply the magnetic flux. The bias circuit generates a bias current for biasing the SQIF at an operating point. The coil generates the bias magnetic field through the SQIF from the bias current of the bias circuit. The bias magnetic field provides nullifying feedback to the SQIF that counterbalances a low-frequency portion of the external magnetic field, such that the output voltage of the SQIF detects a high-frequency portion of the external magnetic field. The circuit can be a receiver with the output voltage of the SQIF detecting an electromagnetic signal while the receiver is moving with changing orientation relative to the Earth's magnetic field.

A magnetic permeable member includes a closed portion and an opened portion. Thus, when the large current flows through a bus bar, the magnetic field is less likely to be strong at the opened portion, thus the large current is easily detectable by a magnetic field detection element arranged at the opened portion. When the small current flows through the bus bar, the magnetic field is more likely to be strong at the closed portion, thus the small current is easily detectable by a magnetic field detection element arranged at the closed portion. Consequently, the magnetic field detection elements can be commonalized to reduce the cost, while allowing the detection of the current in a wide range.

  • Patent number: 10672266
    Abstract: A system and method are disclosed for using magnetic signatures at predetermined positions along a roadway to monitor traffic travelling along the roadway by comparing the predetermined magnetic signatures with magnetic signatures being dynamically and continuously measured by each vehicle as they travel along the roadway. Magnetometers incorporated into mobile devices or otherwise incorporated within the vehicle measure magnetic signatures for comparison to the predetermined magnetic signatures that form a connection graph or database of points that correspond to possible paths along a roadway. When a magnetic signature match is made, the system recognizes that the vehicle has passed a particular point on a roadway and forwards that information to the appropriate entity for further processing, analysis, or toll assessment.

  • Patent number: 10641843
    Abstract: The invention relates to a circuit or microchip for the detection of poor sources of (or very weak) electrical and/or magnetic fields. In one embodiment a device of the present invention includes a microchip consisting of a plate with a plurality of cells, each cell includes a crystal suspended in a semiconducting polymer and piece of metal wire. The cell is insulated by another polymer. A voltage is applied to parallel wires running on each side of the cell, thus inducing a first (or static, or initial) voltage when measured from the cell to the wire. Changes in magnetic or electrical fields are detected by noting a change in voltage from the cell, which is caused by the crystal changing orientation due to the change in the field the circuit is subjected to.

  • Patent number: 10620276
    Abstract: A magnetic detection device that is reduced in size and thickness, but also accurate, includes a substrate and an element disposed on the substrate and including a magneto-sensitive wire sensing an external magnetic field component in an extending direction and a detection coil looping around the magneto-sensitive wire. The magnetic detection device further includes a magnetic field deflector deflecting an external magnetic field around the magneto-sensitive wire, and having a nonmagnetic material core part and a soft magnetic material shell part covering an outer side of at least part of the core part. The magnetic field deflector has a hollow, rather than solid, structure of soft magnetic material. The soft magnetic material volume is therefore significantly smaller, and the hysteresis caused in the magnetic field deflector is remarkably reduced. With the magnetic detection device, the magnetic field component orthogonal to the substrate is also detected with higher accuracy.

  • Patent number: 10565332
    Abstract: In an approach for providing simulation results of an interaction between a transducer head and a magnetic medium, a computer identifies a first raster scan of a sample via a scanning probe microscope. The computer generates a topography image based on the first raster scan of the sample. The computer identifies one or more reference features within the created topography image. The computer calculates an average height based on the one or more reference features. The computer determines a lift distance associated with a probe of the scanning probe microscope. The computer defines a uniform plane based on the calculated average height and the determined lift distance. The computer performs a second raster scan of the sample based on the defined uniform plane. The computer generates a fly-height image based on the second raster scan. The computer provides simulation results based at least in part on the second raster scan.
