  • Position control actuator system
    Patent number: 7246489
    Abstract: A position control actuator system includes a control element and first and second actuators. The first and second actuators are each comprised of magneto-active twinned material. The first actuator is configured to extend and drive the control element in a first direction when the first actuator is subjected to a magnetic field. The second actuator is configured to extend and drive the control element in a second direction when the second actuator is subjected to a magnetic field. A magnetic field source subsystem is configured to extend the first actuator to drive the control element in the first direction, and extend the second actuator to drive the control element in the second direction.

  • Method and apparatus for determining electrical properties of structures
    Patent number: 7167009
    Abstract: A method and apparatus for determining an electrical property of a structure. The method involves creating a model of an electrical property of a structure and measuring the electrical property of the structure between at least two of a plurality of locations. The method also involves determining the electrical property of at least a portion of the structure based on the model and the measurement of the electrical property between the at least two of the plurality of locations.
