Patent number: 7901524Abstract: Apparatus and associated methods for actuating variable stiffness material (VSM) structures and achieving deformation of the structures. The apparatus and the associated methods use internal embedded actuation elements and/or externally attached elements to the VSM structures to achieve the desired deformation. In particular, the actuation can be changed due to the variable stiffness nature of the materials. That is, the invention provides the ability to control the deformation of structures using local stiffness control over subregions of the component in addition to or in substitution for actuation. Furthermore, the invention exploits the variable stiffness properties of the VSM structures to enable new functionalities impossible to realize with conventional constant stiffness materials.Type: GrantFiled: February 3, 2006Date of Patent: March 8, 2011Assignee: HRL Laboratories, LLCInventors: Geoffrey McKnight, Bill Barvosa-Carter, Chris Henry, Andrew Keefe, Richard Ross, Guillermo Herrera

Patent number: 7298017Abstract: In one embodiment, a solid state actuator is provided having a solid state lithium storage material and a solid state volume changing material having a metal capable of changing volume in response to lithium insertion and removal. A solid state lithium ion transport material is located between the lithium storage material and the volume changing material. A pair of electrodes are connected so as to be capable of providing an actuation voltage across the lithium storage material and the volume changing material. In some embodiments, the volume changing material has active material particles comprised of metal contained in an inactive matrix. The active material particles may be aligned so that when the active material particles expand the volume changing material expands substantially in one direction. In some embodiments the volume changing material is a metal alloy and the lithium transport material is a high stiffness material. In some embodiments, multiple actuators are stacked, interleaved, or pillared.Type: GrantFiled: August 28, 2004Date of Patent: November 20, 2007Assignee: HRL Laboratories, LLCInventors: Ping Liu, Cameron Massey, Leslie Momoda, Geoffrey McKnight, William Barvosa-Carter, Alan Jacobsen

Publication number: 20060267376Abstract: An airflow control device comprises a body and an active material in operative communication with the body. The active material, such as shape memory material, is operative to change at least one attribute in response to an activation signal. The active material can change its shape, dimensions and/or stiffness producing a change in at least one feature of the airflow control device such as shape, dimension, location, orientation, and/or stiffness to control vehicle airflow to better suit changes in driving conditions such as weather, ground clearance and speed, while reducing maintenance and the level of failure modes. As such, the device reduces vehicle damage due to inadequate ground clearance, while increasing vehicle stability and fuel economy. An activation device, controller and sensors may be employed to further control the change in at least one feature of the airflow control device such as shape, dimension, location, orientation, and/or stiffness of the device.Type: ApplicationFiled: November 5, 2004Publication date: November 30, 2006Inventors: Geoffrey McKnight, Cameron Massey, Guillermo Herrera, William Barvosa-Carter, Nancy Johnson, Alan Browne
