  • Patent number: 9638756
    Abstract: A system and method for estimating the residual fatigue life of a load cell includes storing, in a memory, fatigue life reference data associated with a test load cell. A predetermined number of data storage bins are provided. Each data storage bin is representative of a predefined value range of peak loads. Peak loads applied to an in-service load cell are detected, and each is stored in an appropriate one of the data storage bins. A number of load cycles of the in-service load cell are calculated based on the detected peak loads stored in each of the data storage bins. An estimate of the residual life of the in-service load cell is calculated from the fatigue life reference data and the calculated number of load cycles of the in-service load cell.

  • Publication number: 20160320206
    Abstract: A position sensor includes a rotor configured to be coupled to the rotatable element for rotation therewith, a non-rotationally mounted stator, a magnet non-rotationally disposed adjacent to the stator and spaced apart from the rotor, a first magnetic sensor non-rotationally mounted between the stator and the rotor, and a second magnetic sensor non-rotationally mounted between the stator and the rotor. The rotor is constructed at least partially of a magnetically permeable material and including a first rotor pole. The stator is spaced apart from the rotor and includes a first stator pole and a second stator pole, which are spaced radially apart from each other. The first magnetic sensor is disposed adjacent the first stator pole and radially offset from the second stator pole, and the second magnetic sensor is disposed adjacent the second main pole and radially offset from the first stator pole.

  • Patent number: 9417098
    Abstract: A position sensor for sensing whether a rotatable element is in at least a first rotational position or a second rotational position is provided. A rotor is configured to be coupled to the rotatable element for rotation therewith, and is constructed at least partially of a magnetically permeable material and includes a first rotor pole. A stator is non-rotationally mounted, is constructed at least partially of a magnetically permeable material, is spaced apart from the rotor, and comprises a first main pole and a first stealer pole. The first main pole and the first stealer pole are spaced radially apart from each other. A magnet is non-rotationally disposed adjacent to the stator and is spaced apart from the rotor. A first magnetic sensor is non-rotationally mounted between the stator and the rotor, is disposed adjacent the first main pole, and is radially offset from the first stealer pole.
