Patent number: 11760228Abstract: Disclosed herein is an electric power and thermal management system in which, when a shaft is rotated due to an operation of a power part, generation of electric power and a circulation of a fluid are performed together so that the generation of the electric power and a circulation structure of oil are integrated, and thus a layout can be reduced, and a structure can be simplified. In addition, in a state in which the generation of the electric power and the circulation structure of the oil are integrated, a circulation amount of the oil is adjusted according to an angle of an inclined plate constituting a pumping mechanism so that an oversupply of the oil to parts through which the oil is circulated can be prevented.Type: GrantFiled: August 3, 2022Date of Patent: September 19, 2023Assignees: Hyundai Motor Company, Kia CorporationInventor: Gwi Taek Kim

Patent number: 11725515Abstract: The disclosure provides rotary machines that include, in one embodiment, a shaft defining a central axis A, the shaft having a first end and a second end. The shaft can have a first gearbox disposed thereon defining one or more cavities therein. At least one contour is slidably received into an arcuate cavity in an exterior surface of the gearbox. The contour has a convex outer surface that cooperates with an inwardly facing curved surface of a housing to form a working volume. A gearbox mechanism consisting of gears, crankshafts, bearings and connecting rod creates an oscillatory motion 2 times per revolution such that the contour can navigate about the arcuate cavity without contacting the cavity at a high rate of rotating speed. Thus, said working volume can expand and compresses twice per rotatable shaft revolution.Type: GrantFiled: May 31, 2022Date of Patent: August 15, 2023Assignee: Lumenium LLCInventors: William Anderson, William Lukaczyk

Patent number: 11723172Abstract: Fan assemblies are disclosed. Fan assemblies include an impeller with asymmetric design. For example, an impeller may include a first set of blades with one geometry and second set of fan blades with another geometry. This enables a dual-inlet centrifugal fan to generate different air flow performance characteristics for the air entering one fan inlet compared to the air entering the other fan inlet. The impeller, with different fan blade configurations, can better handle air flow entering the fan assembly through different inlets, particularly when the air flow conditions differ through the inlets due to impeding structures (e.g., motor, struts, etc.). As a result, air flow distribution from air leaving the impeller, including the locations associated with the different fan blade configurations, is relatively uniform. Beneficially, when air flow distribution uniformity increases, the fan assembly operates more efficiently, as air flow pressure losses due to flow separation are mitigated.Type: GrantFiled: September 23, 2021Date of Patent: August 8, 2023Assignee: APPLE INC.Inventors: Anthony Joseph Aiello, Brett W. Degner, Jesse T. Dybenko, Arash Naghib Lahouti, Eric R. Prather
