Patents by Inventor Dillon J. Thomasson

Dillon J. Thomasson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Electric motor with bar wound stator and end turn cooling
    Patent number: 11923739
    Abstract: An electric motor includes an end turn ring and a cooling structure that is in a thermally conductive relationship with the end turn ring.
    Type: Grant
    Filed: May 31, 2022
    Date of Patent: March 5, 2024
    Assignee: APPLE INC.
    Inventors: Dillon J. Thomasson, Kan Zhou, Rui Guan, Yateendra B. Deshpande, William M. Price
  • Propulsion System
    Publication number: 20230286386
    Abstract: A propulsion system includes a first portion and a second portion that are independently controlled from one another. The first portion includes a first inverter and a first electric motor. The second portion includes a second inverter, a second electric motor, and a second disconnect link. A control system is configured to detect a fault in the first portion, the second portion, or combinations thereof, and determine a response to the fault. In one example, on detection of the fault in the second portion, the second disconnect link is disengaged to reduce electromagnetic drag torque by the second electric motor.

  • Vehicle deceleration system
    Patent number: 11498561
    Abstract: A vehicle includes a control system, a sensing system that senses an environment of the vehicle, and a propulsion system, a braking system, and a steering system that are operated by the control system to navigate the vehicle according to the sensing system and without direct human control. The propulsion system and the braking system are operated by the control system to cooperatively decelerate the vehicle. The braking system includes an inboard friction brake that is associated with one or more wheels of the vehicle and does not form unsprung mass of the vehicle.

  • Converter employing differing switch types in parallel
    Patent number: 11251622
    Abstract: Aspects of the present disclosure involve an inverter employing switches of different types in parallel. In one example, an apparatus includes a voltage-source converter that may have a plurality of switch positions collectively coupled to convert an input to an output. At least one switch position may include a first switch of a first switch type and a second switch of a second switch type different from the first switch type. Also, the first and second switches may be coupled in parallel. The converter may also include a switch control circuit to generate, for each of the at least one of the switch positions, a first control signal to operate the first switch of the switch position, and a second control signal to operate the second switch of the switch position.
