    摘要: A control system for a motor including a rotor comprises a sensorless sensor module that includes a saliency-based estimator module that generates a first rotor position signal based on saliency and a back electromotive force (emf) estimator module that generates a second rotor position signal based on back emf. A selector selects the first rotor position signal for rotor speeds below a first rotor speed and the second rotor position signal for rotor speeds above the first rotor speed. A rotor position sensor senses a position of the rotor and generates a third rotor position signal. A fault detection module senses faults in the rotor position sensor and outputs the third rotor position signal when a fault is not detected and one of the first and second rotor position signals when the fault is detected. An indirect field oriented control (IFOC) system controls the motor based on a selected one of the first, second and third rotor position signals.

    摘要: A method for transacting intellectual property includes the steps of licensing an IP right corresponding to an IP asset to a licensee according to an agreement; receiving a payment from the licensee for the IP right according to terms of the agreement; and if a call or put option provision in the agreement is exercised, then receiving payment of the strike price and transferring ownership of the IP asset to the licensee. The call option provision provides the licensee the right to purchase the IP asset at a predetermined strike price within a specified time period. The put option provision provides the IP owner a right to sell the IP asset at a predetermined strike price.

    摘要: A vehicular wheel assembly includes a first bearing component configured to be coupled to a frame of a vehicle, a second bearing component rotatably coupled to the first bearing component, and a brake mechanism coupled to the second bearing component. The motor includes a stator and a rotor. The stator is coupled to the first bearing component and the rotor is coupled to the second bearing component such that rotation of the rotor relative to the stator causes the second bearing component to rotate relative to the first bearing component. The brake mechanism is between the motor and the frame and is configured to slow the rotation of the second bearing component and the rotor.
