  • Publication number: 20180172421
    Abstract: Different approaches for providing increased redundancy in determining a position of a rotating member, for example, a motor shaft, with galvanically isolated sensors. In one aspect, two separate on-axis sensing chips are positioned in line with one another on a PCB but each on opposite sides or surfaces of the PCB. Respective sensing surfaces are essentially parallel to one another. Advantageously, greater electrical isolation is provided by placing the two sensors on opposite sides of the PCB.

  • Publication number: 20180170417
    Abstract: A method of operating a payload-carrying vehicle having two laterally disposed wheels positioned along a central axis is described. The method includes measuring a force applied by a user to the hand truck, where the measured force comprising a direction and a magnitude, and providing torque to each wheel to cause each wheel to rotate in a respective direction as a function of the measured magnitude and direction. The amount of torque provided to each wheel in response to the force from the user is such that the magnitude of measured force applied by the user is not greater than a predetermined threshold value.

  • Patent number: 7979179
    Abstract: An apparatus and method for a pitch state estimator is provided. The pitch state estimator generates a pitch state signal for establishing the orientation used in the control of a ground-traversing vehicle. The vehicle has a support for supporting a load which is preferably a human passenger. In one embodiment, the pitch state estimator includes a pitch sensor connected to the vehicle producing a pitch signal representing an estimate of a pitch angle of the vehicle. The pitch angle is associated with a coordinate system referenced to gravity. The pitch state estimator also includes at least one inertial reference sensor connected to the vehicle producing an inertial orientation signal with respect to the vehicle. Further included is a state estimator module for receiving the pitch signal and the inertial orientation signal and calculating a pitch state signal from the inertial orientation signal and the pitch signal sensor.
