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:

361/784000

Abstract:

An electronic memory module, on the order of 1 Gigabyte or more, which is compact, results in minimum transmission delay, and which may be incorporated into existing computer systems. The electronic module for use in memory arrays includes a module substrate, a plurality of daughter boards edge-mounted to the module substrate, wherein each daughter board of the plurality of daughter boards includes a front face and a back face opposite the front face, and at least one memory chip mounted to the front face of each daughter board of the plurality of daughter boards, such that the at least one memory chip is in electrical communication with the module substrate. A method of constructing the memory module having a high data bus bandwidth includes providing a plurality of daughter boards, wherein each daughter board has a front face and a back face opposite the front face, mounting at least one memory chip on the front face of each daughter board of the plurality of daughter boards, and edge-mounting the plurality of daughter boards, to a module substrate, such that the memory chips are in electrical communication with the module substrate thereby forming a memory module.

US Classification:

702/065000, 702/188000

Abstract:

An electromagnetic emission source identification apparatus is provided, the identification apparatus comprising a sensor device, a data transmitter, and a computer device. The sensor device is configured to sense an electromagnetic emission from a source, wherein the electromagnetic emission is sensed by the sensor device as corresponding sensed emission data. The data transmitter is in communication with the sensor device and is configured to transmit the sensed emission data from the sensor device. The computer device is configured to be in communication with the data transmitter. The computer device is further configured to process digital emission data, the digital emission data corresponding to the sensed emission data, so as to determine an identification indicator, an operational characteristic indicator, and/or an accessory characteristic indicator corresponding to the source. The processed digital emission data for the source is then compared to the corresponding identification indicator, operational characteristic indicator, and/or accessory characteristic indicator of each of a plurality known sources in a database operably engaged with the computer device so as to determine a best-match known source corresponding to the source. Associated methods as well as an associated computer device and computer software program product are also provided.

International Classification:

E21B 47/12

US Classification:

1662551

Abstract:

An apparatus and method may operate to mount one or more communication assemblies relative to the exterior of a casing being placed in a borehole. Two communication assemblies can be placed in longitudinally spaced relation to one another along the casing, wherein each communication assembly is configured to obtain data from RFID tags in one or more azimuthally oriented regions of the annulus surrounding the casing, and to interrogate RFID tags in a first fluid in the borehole. Additional apparatus, systems, and methods are disclosed.

International Classification:

E21B 47/12
G06K 19/077

US Classification:

3408548, 235492

Abstract:

A radio frequency identification (RFID) tag can include a die attached to an inductive-capacitive (LC) circuit including a capacitive element coupled to an inductive element. The LC circuit can have a resonant frequency that varies according to properties of fluid proximate the RFID tag. The RFID tag can further include a coating material disposed around the die to form an outer surface of the RFID tag. The coating material may have a thickness over a portion of the LC circuit, to permit a conductivity property of a fluid proximate the outer surface to affect the resonant frequency of the LC circuit such that the resonant frequency shifts to a second resonant frequency. Additional apparatus, systems, and methods are disclosed.
