Patents by Inventor Bryan Thomas Siegel

Bryan Thomas Siegel 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).

  • System and method for efficiently operating multiple flywheels
    Patent number: 9141095
    Abstract: A flywheel assembly may include first and second flywheels having respective first and second flywheel parasitic load profiles. Operating speeds of the first and second flywheels may be selected based at least in part on the first and second flywheel parasitic loads. The operating speeds may be determined such that an aggregate of the first and second flywheel parasitic loads is minimized, thereby increasing the efficiency of the flywheel assembly.
    Type: Grant
    Filed: August 9, 2012
    Date of Patent: September 22, 2015
    Assignee: Caterpillar Inc.
    Inventors: Bryan Thomas Siegel, Evan Earl Jacobson, Timothy Michael O'Donnell
  • Prediction control strategy for hybrid machinery
    Patent number: 9139188
    Abstract: A computing system may provide guidance to a vehicle with hybrid power systems on how to efficiently engage the hybrid systems and the primary power source on a given plan. As a result, additional efficiency may be obtained.

  • Hybrid engine assembly and method
    Patent number: 9050968
    Abstract: A hybrid engine assembly may include an engine having a crankshaft, a supplemental shaft mechanically coupled to the crankshaft, a flywheel energy storage assembly, and an auxiliary device. A flywheel clutch may selectively couple the flywheel assembly to the crankshaft. The assembly may be selectively operated in an engine restart mode by directly coupling the flywheel energy storage assembly to the crankshaft prior to starting the engine, and in an auxiliary power mode by directly coupling the flywheel energy storage assembly to the auxiliary device.
