US Patent:

6650636, Nov 18, 2003

Filed:

Oct 20, 1999

Appl. No.:

09/421961

Inventors:

Steven H. Bradshaw - Escondido CA
Bruce L. Carneal - Del Mar CA
Karl E. Moerder - Poway CA
Michael J. Theiss-Aird - Carlsbad CA

Assignee:

Tachyon, Inc. - San Diego CA

International Classification:

H04L 1266

US Classification:

370352, 370474, 370522, 725 63

Abstract:

Transmission of TCP/IP data over a satellite link from a hub station to a plurality of remote units. The data, transmitted over the satellite link, uses the digital video broadcast (DVB) protocol. A field in the DVB header is used to indicate the location of the start of a new TCP/IP data packet within the DVB data. Use of a field in the DVB header to indicate the location of the start of a new TCP/IP data packet supports variable location of TCP/IP data within a DVB frame, and therefore more efficient use of the DVB bandwidth.

Appl. No.:

09/407645

Inventors:

Bruce L. Carneal - Del Mar CA, US
Min Zhu - San Diego CA, US
Steven H. Bradshaw - Escondido CA, US

Assignee:

Tachyon, Inc. - San Diego CA

International Classification:

H04Q 7/38

US Classification:

370329, 370330, 370343, 370478, 370480, 455450, 455509

Abstract:

A system and method for allocating one or more portions of the frequency spectrum among a plurality of radio frequency (RF) transmitters and/or receivers. The system comprises a hub station that dynamically allocates the frequency spectrum in response to demand of the plurality of RF transmitters and/or receivers. Based on the demand, the hub station analyzes the state of performance of one or more groups of RF transmitters and/or receivers, and optimizes utilization of the assigned frequency spectrum.

Assignee:

The Boeing Company - Chicago IL

International Classification:

H01R 12/00

US Classification:

439 63, 439581, 333260

Abstract:

An electrical interconnect system includes a first circuit board that includes at least one via, and a conductor configured to transmit an electrical current therethrough. The conductor includes a first signal contact extending from a conductor first end, and a dielectric cylinder configured to receive the conductor therethrough. The dielectric cylinder includes a first bellows element extending from a first end of the dielectric cylinder that is positioned adjacent to the first signal contact. The first bellows element and the dielectric cylinder are configured to form a substantially continuous outer conductor, wherein the conductor and the first bellows are configured to electrically interface to the via and maintain connection thereto using a biasing force.

H01Q 1/50

US Classification:

343787

Abstract:

The present invention relates to active electronically scanned array antennas. A thin, low cost design is provided by coupling electromagnetic energy into periodically driven long slots () using circulators with integrated probes (). The long slots () are formed as grooves () in a conductive base plate (), each groove () bracketed on both sides by conductive strips (). The circulators with integrated probes () are installed between the conductive strips () and the base plate (), to reduce fabrication costs of the machined parts and to facilitate the making of connections between the circulators and the antenna electronics. The probes () protrude partway into the slots () and provide coupling to waves propagating in free space.
