Patent number: 11686223Abstract: A system includes an electric generator, a power electronics system, a first heat exchanger, and a second heat exchanger. The electric generator includes a turbine wheel, a rotor, and a stator. The turbine wheel is configured to receive process gas and rotate in response to expansion of the process gas flowing through the electric generator. The rotor is configured to rotate with the turbine wheel. The electric generator is configured to generate electrical power upon rotation of the rotor within the stator. The power electronics system is configured to receive the electrical power from the electric generator and convert the electrical power to specified power characteristics. A heat transfer fluid receives waste heat from the power electronics system through the first heat exchanger. The heat transfer fluid transfers the received waste heat to the process gas through the second heat exchanger.Type: GrantFiled: April 7, 2022Date of Patent: June 27, 2023Assignee: Sapphire Technologies, Inc.Inventors: Jeremy Liu, James Ryan Yates

Publication number: 20220389831Abstract: An impeller is configured to be rotated by a flowing fluid. A fluid stator includes a fixed ring parallel to a plane of rotation of the impeller. The fixed ring has a center in-line with a center of rotation of the impeller. A rotatable ring is rotatable relative to, and parallel to, the fixed ring. The rotatable ring has a center in-line with a center of rotation of the impeller. Stator vanes extend between the fixed ring and the rotatable ring. The stator vanes define an inlet cross sectional area upstream of the impeller. The cross sectional area is dependent upon a relative position of the fixed ring and the rotatable ring. An actuator is configured to rotate the rotatable ring. An electric rotor is coupled to, and configured to rotate in unison with, the impeller. An electric stator encircles the electric rotor. The electric stator includes coil windings.Type: ApplicationFiled: June 8, 2021Publication date: December 8, 2022Inventors: Jeremy Liu, Archie A.T. Andonian, Freddie Sarhan, John Stout, James Ryan Yates

Patent number: 9623811Abstract: A deployable camera system for a vehicle includes a body defining a cavity therein, and a camera including a housing having an exterior surface. The camera is reversibly transitionable between a stowed position in which the camera is recessed into the cavity and the exterior surface is substantially flush with the body, and a deployed position wherein the camera protrudes from the cavity and the exterior surface is not substantially flush with the body. The deployable camera system includes a first shape memory alloy element transitionable between a first state and a second state in response to a first thermal activation signal.Type: GrantFiled: January 30, 2014Date of Patent: April 18, 2017Assignees: GM Global Technology Operations LLC, DYNALLOY, INC.Inventors: Paul W. Alexander, Debbie E Nachtegall, Nancy L. Johnson, Scott R. Webb, James Ryan Yates, James Holbrook Brown, Aragorn Zolno

Patent number: 8864392Abstract: A camera system includes a body defining a cavity therein, and a camera attached to the body within the cavity and including a lens. The camera system also includes a shape memory alloy transitionable between a first state and a second state in response to a thermal activation signal, and a wiper configured for wiping debris from the lens. The wiper is attached to the camera and is actuatable by the shape memory alloy. The shape memory alloy transitions between the first state and the second state to actuate the wiper so that the wiper contacts and translates across the lens and thereby wipes debris from the lens.Type: GrantFiled: February 7, 2013Date of Patent: October 21, 2014Assignee: GM Global Technology Operations LLCInventors: Paul W. Alexander, Alan L. Browne, Nancy L. Johnson, James Holbrook Brown, James Ryan Yates, Brian W. Bowling, James Q. La, Aragorn Zolno

Patent number: 8844281Abstract: A heat engine includes a first rotatable pulley and a second rotatable pulley spaced from the first rotatable pulley. A shape memory alloy (SMA) element is disposed about respective portions of the pulleys at an SMA pulley ratio. The SMA element includes a first wire, a second wire, and a matrix joining the first wire and the second wire. The first wire and the second wire are in contact with the pulleys, but the matrix is not in contact with the pulleys. A timing cable is disposed about respective portions of the pulleys at a timing pulley ratio, which is different than the SMA pulley ratio. The SMA element converts a thermal energy gradient between the hot region and the cold region into mechanical energy.Type: GrantFiled: December 30, 2011Date of Patent: September 30, 2014Assignees: GM Global Technology Operations LLC, Dynalloy, Inc, The Regents of the University of MichiganInventors: Alan L. Browne, Nancy L. Johnson, John Andrew Shaw, Christopher Burton Churchill, Andrew C. Keefe, Geoffrey P. McKnight, Paul W. Alexander, Guillermo A. Herrera, James Ryan Yates, Jeffrey W. Brown
