  • Patent number: 10527686
    Abstract: A method and system are provided for performing magnetic anomaly sensing. Each of two magnetometers generates magnetic field measurements. The magnetometers define a one-dimensional gradiometer having a baseline between them. A difference value is generated using the magnetic field measurements. The magnetometers are independently moved to maintain the baseline when the difference value is unchanging. Detection of a magnetic anomaly by a first magnetometer is indicated when the difference value deviates. The second magnetometer is then maneuvered until the magnetic field measurements generated thereby are indicative of detection of the magnetic anomaly by the second magnetometer. When this occurs, an adjusted baseline is defined between the magnetometers. At least one of the magnetometers is maneuvered to position the adjusted baseline in each of three orthogonal dimensions.

  • Patent number: 10523199
    Abstract: Inductive Proximity Sensors are non-contact sensing devices used in manufacturing processes to sense metal targets. In practice, it is common for objects to contact the sensor causing the sensor to malfunction. An inductive sensor with improved durability is required. An inductive proximity sensor includes an exterior housing, an interior sensing coil and electronic circuit, and a connector. The Exterior housing is produced from one piece of metal bar, bored from one end to the tip of the other end, leaving the cylindrical tube open only on one end. The Exterior Housing is produced with an Inside Dimension that is smaller than previous proximity sensors and places the coil and electronic circuit further away from the Outside Dimension of the Exterior Housing. The interior sensing coil and electronic circuit are protected by the thick casing of the Exterior housing to improve structural rigidity and the longevity of operation in manufacturing processes.
