Patents by Inventor Edward Arthur Hill

Edward Arthur Hill has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6677695
    Abstract: A movable microelectromechanical mirror structure for a microelectromechanical structure (MEMS) has an actuator (electrodes) for the moving mirror. The electrodes are situated at a predetermined angle to the horizontal thus improving the relationship between force applied on the mirror and the gap between the mirror and the electrodes. The angular electrode placement is achieved by the provision of a deformable electrode support member mounted on the substrate, with at least one of the electrodes mounted on the electrode support member, and a deforming element mounted against the deformable electrode support member such as to permanently maintain the deformable electrode support member in a deformed state.
    Type: Grant

  • Patent number: 6229684
    Abstract: A variable capacitor having low loss and a correspondingly high Q is provided. In addition to a substrate, the variable capacitor includes at least one substrate electrode and a substrate capacitor plate that are disposed upon the substrate and formed of a low electrical resistance material, such as HTS material or a thick metal layer. The variable capacitor also includes a bimorph member extending outwardly from the substrate and over the at least one substrate electrode. The bimorph member includes first and second layers formed of materials having different coefficients of thermal expansion. The first and second layers of the bimorph member define at least one bimorph electrode and a bimorph capacitor plate such that the establishment of a voltage differential between the substrate electrode and the bimorph electrode moves the bimorph member relative to the substrate electrode, thereby altering the interelectrode spacing as well as the distance between the capacitor plates.
