Patent number: 11159074Abstract: Embodiments of cooling a motor controlling using a motor are disclosed. In some embodiments, a system includes an electric motor including at least one rotor with integrated features positioned and configured to pull air into and through the electric motor. The system also includes at least one motor controller each comprising a heat sink positioned in an air intake path from a source of air to the electric motor. A method of manufacturing the system includes arranging at least one motor controller and at least one electric motor, coupling the at least one motor controller and at least one electric motor via a flexible duct, and adapting the arrangement of the at least one motor controller and the at least one electric motor to passively provide cooling via airflow through the at least one motor controller and at least one electric motor in proportion to a load on the at least one electric motor.Type: GrantFiled: February 28, 2020Date of Patent: October 26, 2021Assignee: Wisk Aero LLCInventors: Geoffrey Alan Long, Justin Char, Nathan Elliot Frank, Robert Wayne Moore, Diederik Marius, Michael John Burgart

Patent number: 10998778Abstract: Embodiments of a modular motor assembly are disclosed. In some embodiments, a motor comprises a plurality of modular magnetic units, where each of the modular magnetic units includes at least one rotor and at least one stator. The motor further comprises a plurality of structural segments each adapted to support a stator of a corresponding one of the modular magnetic units, where each of the structural segments interlocks with a next structural segment to form a stack. A method of manufacturing a motor includes arranging a selected number of modular magnetic units, coupling the selected number of modular magnetic units to a shaft, coupling the selected number of modular magnetic units to respective structural segments, and forming electrical connections to apply three-phase voltage to stator windings of the modular magnetic units.Type: GrantFiled: July 31, 2019Date of Patent: May 4, 2021Assignee: WISK AERO LLCInventors: Geoffrey Alan Long, Justin Char, Robert Wayne Moore, Laura Weeks Shane, Diederik Marius

Publication number: 20060051727Abstract: A method on a computing device is provided for enhancing the memory and cognitive ability of an older adult by requiring the adult to spatially match pairs of graphically presented response buttons that are associated with aurally presented stimuli which is processed by the computing device. An adult is presented with a grid of response buttons that have been paired with aural stimuli. As the adult selects a response button, its processed aural stimuli is presented. The adult is required to remember which response button is associated with which aural stimuli, and sequentially select response buttons having the same aural stimuli. As the adult sequentially selects response buttons having the same aural stimuli, the response button pair is removed. The number of response buttons presented in a trial, and the amount of processing applied to the stimuli adapts to the adults success or failure in completing trials.Type: ApplicationFiled: October 6, 2005Publication date: March 9, 2006Applicants: Neuroscience Solutions CorporationInventors: Daniel Goldman, Joseph Hardy, Henry Mahncke, Michael Merzenich, Jeffrey Zimman, Justin Char, Daniel Harrington
