Filed:

Oct 23, 2000

Appl. No.:

09/694835

Inventors:

Philip A. Deane - Durham NC
Joseph Mancusi - Durham NC
Mark W. Roberson - Cary NC

Assignee:

MCNC - Research Triangle Park NC

International Classification:

H01G 501

US Classification:

361278, 361277, 361292, 3612982, 361291

Abstract:

A microelectromechanical system (MEMS) tunable capacitor having low loss and a corresponding high Q is provided. The tunable capacitor includes a first substrate having a first capacitor plate disposed thereon. A fixed pivot structure is disposed on the first surface of the first substrate, proximate the first capacitor plate. The fixed pivot structure as a point of attachment for a flexible membrane that extends outward from the fixed pivot and generally overlies the first capacitor plate. A second substrate is attached to the underside of the flexible membrane and a second capacitor plate is disposed thereon such that the first and second capacitor plates face one another in a spaced apart relationship. A MEMS actuator is operably in contact with the flexible membrane for the purpose of providing an actuation force to the flexible membrane, thereby varying the capacitance between the first and second capacitor plates. In one advantageous embodiment of the invention the first and second capacitor plates are formed of an HTS material and the first and second substrates may be formed of a low signal loss material that is compatible with the HTS materials.

US Classification:

359210, 359204, 372 20, 372 50

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.

International Classification:

H01P005/00

US Classification:

333 24R, 333109, 333116

Abstract:

Three dimensional electronic and optical coupling devices that are capable of providing high speed coupling over a large frequency range while limiting the amount of space consumption in the communications network. An optical or electrical coupling device comprises a first substrate and a second substrate adjacent to the first substrate having one or more optical waveguides or microstrips formed thereon. The substrates will have disposed thereon conductive microstrips and/or dielectric elements. The one or more optical waveguides or microstrips formed on the first substrate correspond to at least one optical waveguides or microstrips formed on the second substrate so as to facilitate optical coupling between the corresponding waveguides. Precise spacing between the substrates and precise spacing between the optical waveguides or microstrips facilitate the requisite optical/RF coupling.
