Publication number: 20050134152Abstract: In accordance with one embodiment of the present application, a piezoelectric diaphragm structure includes a diaphragm, with a piezoelectric material located on the diaphragm. The piezoelectric material is being poled in a radial direction to the piezoelectric material, wherein the poling direction is in-plane with the piezoelectric material. An inter-digitated electrode grid is positioned on a first surface of the piezoelectric material, the inter-digitated electrode grid including a plurality of electrodes configured to selectively receive positive and negative voltage. The application of the positive and negative voltages generate electric fields in the piezoelectric material, at least a portion of which are in-plane with the piezoelectric material, resulting in an actuation of the piezoelectric material, causing a length change of the piezoelectric material in the Radial direction.Type: ApplicationFiled: December 18, 2003Publication date: June 23, 2005Inventors: Meng Lean, Steven Buhler, John Fitch, Karl Littau

Patent number: 4988021Abstract: A collapsible clothes hanger molded in one piece of a flexible material has a pair of hanger arms which are moved from a collapsed position to an extended position by one hand exerting s squeezing force on the flexible connections between the pair of hanger arms and a pair of flexible links that extend between the hanger arms and a center support member. The bendable links, whose motion is restricted by the center support member, fold upon themselves and draw the hanger arms upward into the extended position. The squeezing force which moves the hanger arms into the extended position lies in a horizontal plane so that the hand of the user can remain in a natural position during extension of the arms to a desired garment-supporting position. The hanger of a preferred embodiment is automatically locked in the extended position once this position is reached. The lock is released by again a single hand exerting a squeezing force, also in a horizontal plane, so that the hanger arms may move the collapsed position.Type: GrantFiled: August 28, 1989Date of Patent: January 29, 1991Assignee: Michael E.
