  • Publication number: 20210311138
    Abstract: A magnetic position sensor comprises a first magnetic rod including a first end and a second end, and a second magnetic rod including a third end and a fourth end, the first end and the third end at a first distance, the second end and the fourth end at a second distance greater than the first distance. The magnetic position sensor further includes a magnet configured to travel relative to the first magnetic rod and the second magnetic rod along a first axis, and one or more magnetic sensors communicatively coupled to the magnet.

  • Publication number: 20190331507
    Abstract: A multi-turn sensor can include first and second shafts having respective rotational axes that are approximately perpendicular to each other, a first magnet provided at an end of the first shaft, and a second magnet provided at an end of the second shaft. The multi-turn sensor can further include a first magnetic sensor provided adjacent the first magnet to allow non-contacting sensing of angular position of the first shaft as the first shaft rotates, and a second magnetic sensor provided adjacent the second magnet to allow non-contacting sensing of angular position of the second shaft as the second shaft rotates. The multi-turn sensor can further include a gear mechanism configured to couple the first shaft and the second shaft, such that the rotation of the first shaft results in the rotation of the second shaft.

  • Publication number: 20190265748
    Abstract: A joystick can include a shaft having an axis, a manipulating portion, and a sensing end with a magnet mounted thereto. The joystick can further include a movement mechanism configured to allow the manipulating portion of the shaft to be moved in three dimensions with respect to the axis of the shaft. The movement of the manipulating portion results in corresponding movement of the magnet that can be sensed in a non-contacting manner by a magnetic sensor positioned relative to the magnet.

  • Patent number: 9927262
    Abstract: High-resolution multi-turn sensing apparatus and methods. A method can be implemented to sense a rotational position of a shaft having a longitudinal axis. Such a method can include determining a turn number of the shaft with a first magnet arranged in a non-contact manner with a first magnetic sensor to allow measurement of a linear position of the first magnet relative to the first magnetic sensor. The linear position can be representative of a turn number of the shaft. The method can further include determining an angular position of the shaft within a given turn with a second magnet positioned at an end of the shaft along the longitudinal axis and arranged relative to a second magnetic sensor. The method can further include combining the turn number with the angular position to generate one or more output signals representative of a measured rotational position of the shaft.

  • Patent number: 9518840
    Abstract: Disclosed are systems and methods for effectively sensing rotational position of an object. In certain embodiments, a rotational position sensor can include a shaft configured to couple with the rotating object. The shaft can be configured to couple with a magnet carrier such that rotation of the shaft yields translational motion of the carrier. A magnet mounted to the carrier also moves longitudinally with respect to the axis of the shaft, and relative to a magnetic field sensor configured to detect the magnet's longitudinal position. The detected longitudinal position can be in a range corresponding to a rotational range of the shaft, where the rotational range can be greater than one turn. In certain embodiments, the rotational position sensor can include a programmable capability to facilitate ease and flexibility in calibration and use in a wide range of applications.

  • Publication number: 20150160042
    Abstract: Devices and methods related to high-resolution multi-turn sensors. In some embodiments, a position sensing device can include a shaft having a longitudinal axis, and a first sensor having a magnet and a magnetic sensor. The magnet can be coupled to the shaft, and the magnetic sensor can be positioned relative to the magnet such that the first sensor allows measurement of an angular position of the magnet relative to the magnetic sensor to thereby allow determination of the corresponding angular position of the shaft within a given turn of the shaft. The position sensing device can further include a second sensor coupled to the shaft and configured to allow measurement of a turn-number of the shaft. The second sensor can include one or more of different types sensing functionalities to yield an output representative of the turn-number of the shaft.
