Patent number: 8347747Abstract: A method for providing torque to assist in moving a component of a mobile platform. Biasing forces may be applied to opposing portions of a torque transferring member that enable the torque transferring member to be maintained in a position of equilibrium. A torque may be applied to one of the component and the torque transferring member such that the biasing forces cooperatively exert a torque on the torque transferring member to assist in moving the torque transferring member out from the position of equilibrium. Motion of the torque transferring member out from the position of equilibrium may be used to assist in moving the component.Type: GrantFiled: January 7, 2009Date of Patent: January 8, 2013Assignee: The Boeing CompanyInventors: Dan J.

Patent number: 7872397Abstract: An energy conversion apparatus having a pair of flexible beams that are supported at first ends thereof from a base. The beams each include at least one piezoelectric material layer. Second ends of each of the beams are operatively coupled to rigid links. The rigid links are in turn operatively coupled to a working element that may form, in one application, a drive member for a motor, or in a second application form a valve element for an electronic fuel injection system, or in a third application form a piston for a fluid pump. The working element is free to move linearly in a path generally parallel to the longitudinal axes of the flexible beams. As electrical signals are applied to and removed from the piezoelectric material layer(s) of each flexible beam, the beams flex repeatedly and uniformly over their full lengths. This causes a linear movement of the working element that can be used to help form a rotational motor output or a linearly moving fluid control element.Type: GrantFiled: February 27, 2007Date of Patent: January 18, 2011Assignee: The Boeing CompanyInventors: Dan J. Clingman, Lynn M. Gravatt

Patent number: 7834301Abstract: A method is disclosed for controlling a flight trajectory of a spinning projectile. In one aspect the method may involve supporting a nose of the projectile in a manner permitting the nose to be wobbled. At least one electrically responsive component may be coupled at a first end to the nose and at a second end to a base portion of the projectile. An angular position of the nose of the projectile may be sensed as the projectile flies through an atmosphere after being fired from a weapon. An electrical signal is controllably applied to the electrically responsive component, in relation to the sensed angular position of the nose, to control an attitude of the nose during flight of the projectile.Type: GrantFiled: April 30, 2008Date of Patent: November 16, 2010Assignee: The Boeing CompanyInventor: Dan J.

Patent number: 7741757Abstract: An energy harvester apparatus that includes a piezoelectric beam having opposing first and second ends, with the first end being fixedly supported to a support structure. A negative spring force subsystem has a first end fixedly secured against movement, and a second end secured to the second end of said piezoelectric beam. The negative spring force subsystem includes a linkage system and a biasing element operably associated with the linkage system for applying an adjustable, negative spring force to the piezoelectric beam to soften the piezoelectric beam. The negative spring force subsystem is adjusted to flex the beam sufficiently to overcome the inherent stiffness of the beam such that two stable positions for the beam are created. The beam is therefore able to oscillate between the two stable positions in an over center fashion in response to a low magnitude vibration signal. In various embodiments the system is implemented to provide an input drive signal to control various types of external devices.Type: GrantFiled: November 13, 2007Date of Patent: June 22, 2010Assignee: The Boeing CompanyInventors: Dan J.

Patent number: 7737608Abstract: A piezoelectric drive motor especially well adapted for use with flow control systems on commercial aircraft, military aircraft and spacecraft. In one embodiment, the apparatus includes a support structure that supports a piezoelectric beam. A biasing element, for example a coil spring, is coupled between a free end of the piezoelectric beam and the support structure. The spring exerts a compressive force on the beam and serves to amplify its displacement when electric signals applied to piezoelectric layers on the beam cause deflection of the beam between two stable positions. The drive motor operates over a wider band of drive frequencies than conventional piezoelectric beams and is also suitable for use as a sensor and in a wide variety of actuator applications.Type: GrantFiled: May 15, 2006Date of Patent: June 15, 2010Assignee: The Boeing CompanyInventors: Robert T Ruggeri, Dan J Clingman

Patent number: 7732994Abstract: A non-linear power generator system that may include a flexible beam for receiving a mechanical input, the flexible beam being supported in a bowed configuration; an electrically responsive member supported adjacent one end of the flexible beam so as to be under a compressive force exerted by the flexible beam; and the flexible beam being adapted to move towards a flattened shape from the bowed shape in response to the mechanical input, to transmit the mechanical input to the electrically responsive member, to cause a compression of the electrically responsive member that results in an electrical output signal being generated by the electrically responsive member.Type: GrantFiled: September 3, 2008Date of Patent: June 8, 2010Assignee: The Boeing CompanyInventors: Dan J.
