Abstract: In some implementations, a device may obtain event data relating to events involving one or more entities and one or more individuals, where the one or more entities are associated with entity categories. The device may determine, based on origin locations of the one or more individuals and locations of the one or more entities, distances between the origin locations of the one or more individuals and the locations of the one or more entities, the distances indicating travel distances of the one or more individuals to perform exchanges in the entity categories associated with the one or more entities. The device may determine, based on the event data and the distances, that a geographic area is associated with an opportunity for an entity category. The device may transmit a notification indicating the opportunity for the entity category in the geographic area.

Abstract: Methods and apparatus are provided for startup of a permanent magnet alternating current (AC) motor. The method comprises the steps of detecting startup of the permanent magnet AC motor; detecting a mechanical oscillation of the permanent magnet AC motor when startup of the permanent magnet AC motor is detected; and, in response to detection of the mechanical oscillation of the permanent magnet AC motor when startup is detected, suppressing the mechanical oscillation of the permanent magnet AC motor.

Abstract: A stator assembly for use with an electric motor includes, but is not limited to, a stator core having an inner surface and a plurality of open slots defined in the inner surface. The stator assembly also includes a winding having multiple conductors. The winding is coupled to the stator core such that a predetermined quantity of conductors is disposed within each open slot. The winding is configured to control a magnitude of a torque ripple produced by operation of the electric motor.

Abstract: Methods and apparatus are provided for stator assembly for use with an electric motor assembly. The stator assembly includes, but is not limited to a stator core that has an inner surface and a plurality of stator slots defined in the inner surface. A fractional slot winding having a plurality of conductors is coupled to the stator core. Each stator slot contains a group of the conductors arranged in a radially adjacent configuration. The groups of conductors in each of the stator slots together form a plurality of concentric rings of conductors. The conductors in each mixed group are arranged such that conductors carrying differing phases of electric current are arranged in a radially alternating configuration.

Abstract: According to an example embodiment, a method is provided for limiting an operational temperature of a motor. The method includes generating a maximum allowable current I*S(max) for a motor based on a temperature difference between a temperature reference T* of a power inverter module and a semiconductor device temperature T of the power inverter module. The method further includes generating a maximum allowable torque T*e(max) based on the maximum allowable current I*S(max) and a maximum allowable flux ?*S(max), and using the maximum allowable torque T*e(max) to limit the torque command T*e in order to suppress the semiconductor device temperature T to below the temperature reference T*.

Abstract: 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.

Abstract: 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.

Abstract: 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.
