  • Patent number: 8710717
    Abstract: Methods are provided for creating a metal or other electrically-conductive member extending from an air-backed cavity of a piezoelectric ultrasonic transducer (pMUT) apparatus defining such an air-backed cavity, through a substrate layer disposed adjacent to the transducer device of the pMUT device, and into electrically-conductive engagement with a first electrode of the pMUT device, such that the electrically-conductive member provides an electrically-conductive engagement between the first electrode and a conformal electrically-conductive layer deposited in the air-backed cavity of the pMUT device. Associated apparatuses are also provided.

  • Patent number: 7449821
    Abstract: A piezoelectric micromachined ultrasonic transducer comprising a substrate and a first dielectric film formed on the substrate. An opening having a sidewall is formed through the substrate and first dielectric film. A bottom electrode is formed on the first dielectric film spanning the opening. A piezoelectric element is formed on the bottom electrode. A second dielectric film surrounds the piezoelectric element. A conformal insulating film is formed on the sidewall of the opening. A conformal conductive film is formed in contact with the bottom electrode and on the sidewall of the opening, wherein an open cavity is maintained in the opening. A top electrode is formed in contact with the piezoelectric element.

  • Patent number: 6924921
    Abstract: A three dimensional photonic crystal and layer-by-layer processes of fabricating the photonic crystal. A substrate is exposed to a plurality of first microspheres made of a first material, the first material being of a type that will bond to the templated substrate and form a self-passivated layer of first microspheres to produce a first layer. The first layer is exposed to a plurality of second microspheres made of a second material, the second material being of a type that will bond to the first layer and form a self-passivated layer of second microspheres. This layering of alternating first and second microspheres can be repeated as desired to build a three dimensional photonic crystal of desired geometry. Charged polymers such as polyelectrolyte coatings can be used to create the bonds.

  • Patent number: 6680788
    Abstract: A scanning apparatus adapted to track or other wise communicate with a remote object is provided, comprising a plurality of individually actuatable laser devices, each laser device emitting a laser beam. The scanning apparatus further comprises a moveable lens member disposed adjacent to the output ports such that the laser beams are directed therethrough, the lens member being moveable and cooperable with the laser devices such that each laser beam is directed in a different direction after passing through the lens member. The scanning apparatus is further configured to provide laser beam agility by selectively actuating individual laser devices so as to coarsely track the remote object and to provide laser beam steerability by moving the lens member with respect to an actuated laser device so as to finely track the remote object. An associated method is also provided.
