Patent number: 7980074Abstract: Active material actuator assemblies are provided that enable simplified control systems and faster actuator cycle times. A movable member is provided that has multiple active material components operatively connected to it. The active material components are separately selectively activatable for moving the movable member. Movement of the movable member via activation of a first of the active material components triggers activation of the second active material component to further move the movable member. Alternatively or in addition, previously activated active material components are protected from undesired stretching during activation of another active material component or, when desired, an active material component may be reset via activation of another of the active material components in order to prepare it for subsequent activation.Type: GrantFiled: August 9, 2006Date of Patent: July 19, 2011Assignee: GM Global Technology Operations LLCInventors: Xiujie Gao, Alan L. Browne, Nancy L. Johnson, Ukpai I. Ukpai

Patent number: 7685859Abstract: A crimping apparatus and method are provided that enable secure crimping of objects to one another even when the objects are subject to thermal or stress cycling. Specifically, an apparatus for crimping a work-piece includes a die pair with a first die that defines a first groove characterized by a first cross-sectional shape as well as a second die opposing the first die. The second die defines a second groove characterized by a second cross-sectional shape different than the first cross-sectional shape. When the dies are moved together for crimping the work-piece, the first and second grooves are aligned to define a die cavity with a compound cross-sectional shape for crimping the work-piece.Type: GrantFiled: February 6, 2007Date of Patent: March 30, 2010Assignee: GM Global Technology Operations, Inc.Inventors: Ukpai I.

Patent number: 7648118Abstract: A flow-regulating valve has at least one active material component that may be passively activated (e.g., in response to changes in surrounding temperature) to control fluid flow through the valve. Additionally, an actuator, which may be of any type, such as a solenoid or even another active material component, actuates due to active activation, such as resistive heating in response to a sensor/control signal, which could be due to external conditions (such as existence of high acceleration) or internal conditions (such as change in fluid temperature) to provide an active level of control of fluid flow through the valve. The flow-regulating valve may be used in an oil level control system of a transmission to ensure adequate oil availability during various operating conditions while minimizing the adverse effects such as spin and windage losses. Similar applications can be made in other fluid flow or fluid level control systems.Type: GrantFiled: February 1, 2007Date of Patent: January 19, 2010Assignee: GM Global Technology Operations, Inc.Inventors: Ukpai I.
