  • Contactless magnetic linear position sensor
    Patent number: 9448087
    Abstract: In a position sensor, two field sensors are placed along a line parallel to the movement to be detected. Two magnets are placed at an angle to each other to generate a magnetic field such that their position is a linear or approximately linear function of the difference between the outputs of the sensors.
    Type: Grant
    Filed: October 10, 2011
    Date of Patent: September 20, 2016
    Assignee: METHODE ELECTRONICS, INC.
    Inventors: Azizur Rahaman, Seong-Jae Lee
  • System and method for determining the state of health of electrochemical battery cells
    Patent number: 9395418
    Abstract: A system and method for determining the state of health of a battery. In particular, the present invention is related to a system and method for determining the state of health of an electrochemical battery cell by obtaining state of charge measurements for the battery cell, and using the state of charge measurements to calculate the state of health of the battery cell, wherein the state of charge measurements are based on the magnetic susceptibility of the battery cell. The system includes a sensing device for measuring the magnetic susceptibility of the battery cell, and a computing device for performing the steps of the disclosed method.
