  • Publication number: 20180018895
    Abstract: Described embodiments include a self-propelled vehicle, method, and system. The self-propelled vehicle includes an autonomous driving system configured to dynamically determine maneuvers operating the vehicle along a route in an automated mode without continuous input from a human driver. The vehicle includes an input device configured to receive a real-time request for a specific dynamic maneuver by the vehicle operating along the route from the human driver. The vehicle includes a decision circuit configured to select a real-time dynamic maneuver by arbitrating between (i) the received real-time request for the specific dynamic maneuver from the human driver and (ii) a real-time determination relative to the specific dynamic maneuver received from the autonomous driving system. The vehicle includes an implementation circuit configured to output the selected real-time dynamic maneuver to an operations system of the vehicle.

  • Publication number: 20170271945
    Abstract: A BLDC motor for driving a cross flow fan in an air-conditioning application has an external rotor and an internal stator. The stator is a salient pole stator with insulated pole teeth and conductor coils. The inner diameter of the stator supports a single bearing. An electronic PCBA for control of the BLDC motor is optionally attached to the stator, all of which is encapsulated in a thermoset resin. The rotor comprises permanent magnet component(s) and a rotor frame. The rotor frame includes a stub axle that engages with the bearing element and features to provide torsional or rotational compliance between the rotor magnets and the fan. A level of compliance is provided between the bearing element and the stator to allow for angular misalignment between the rotational axis of the fan and the stator.
