Patents by Inventor Anastasios ARVANITIS

Anastasios ARVANITIS 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).

  • Methods of reducing vibrations for electric motors
    Patent number: 12199532
    Abstract: A method of controlling an electric motor includes pulsing the electric motor and phase shifting the modulation frequency. Pulsing the electric motor at the modulation frequency propels a vehicle to increase efficiency of the electric motor. Phase shifting the modulation frequency includes phase shifting between 0 degrees and 180 degrees to reduce vibrations induced in the vehicle.

  • Universal cloud data ingestion for stream processing
    Patent number: 12095794
    Abstract: An example method includes accessing, by a data platform via a network, data from one or more cloud environments; identifying, by the data platform and in the data, first data associated with a first entity and a first data type and second data associated with a second entity and a second data type; mapping, by the data platform and based on the first entity and the first data type, the first data to a first data stream of a data streaming platform; mapping, by the data platform and based on the second entity and the second data type, the second data to a second data stream of the data streaming platform, the second data stream different from the first data stream of the data streaming platform; and generating, based on the first data stream, a graph representing activity associated with the first entity in the one or more cloud environments.

  • Noise, vibration and harshness reduction in a skip fire engine control system
    Patent number: 11555461
    Abstract: A variety of methods and arrangements for reducing noise, vibration and harshness (NVH) in a skip fire engine control system are described. In one aspect, a firing sequence is used to operate the engine in a skip fire manner. A smoothing torque is determined that is applied to a powertrain by an energy storage/release device. The smoothing torque is arranged to at least partially cancel out variation in torque generated by the skip fire firing sequence. Various methods, powertrain controllers, arrangements and computer software related to the above operations are also described.
