US Patent:

20130308732, Nov 21, 2013

Filed:

May 21, 2013

Appl. No.:

13/899529

Inventors:

Robert Holland - Moorestown NJ, US
Paul Dourbal - Princeton Junction NJ, US
Yanhua Deng - Gainesville FL, US
Paul Prucnal - Princeton NJ, US
Andrew McCandless - Baton Rouge LA, US

International Classification:

H04B 1/10

US Classification:

375346

Abstract:

An interference cancellation system (ICS) may be used with a communication system to prevent or minimize interference from one or more sources. The ICS may receive radio frequency (RF) signals comprised of one or more signals of interest (SOI) and multiple interfering signals. An interference estimation processor (IEP) may be used to estimate the one or more interfering signals. The interfering signals may be estimated using spatial and/or time diversity, which may be combined with statistical methods. The estimated interfering signals may be sent to the ICS, which may use the estimated interference signal to cancel the interference and output the SOI.

International Classification:

H04K 3/00

US Classification:

398 39

Abstract:

An interference cancellation system (ICS) may be used with a communication system to prevent or minimize interference from one or more sources. The ICS may receive radio RF signals comprised of one or more signals of interest (SOI) and multiple interfering signals. The ICS may use a sample of the interfering signals to cancel the interfering signals from the SOI. The multiple interfering signals may be converted into a single optical signal for cancellation. One or more optical cancellation paths may be used for interference cancellation. Each optical cancellation path may include an optical attenuator and/or an optical delay to achieve phase shifts and/or delays for interference cancellation.

International Classification:

H04B 1/10

US Classification:

455 631

Abstract:

Systems and methods for cancelling interference from a received signal in order to properly detect a signal of interest are disclosed. A combined signal of interest plus interference signal may be received. A copy or sample of the interference signal may be determined. The interference signal and the combined signal of interest plus interference signal may be converted to the optical domain. The interference signal may be optically phase shifted by −180 degrees, which may result in an optically inverted interference signal. The optically inverted interference signal may be variably optically attenuated and/or variably optically time delayed, for example based on a detected output power of an optical subsystem of the interference cancellation system. As a result, interference cancellation of the interference signal from the combined signal of interest plus interference signal may be achieved, resulting in 50 dB or more of cancellation of the interference signal.

Appl. No.:

9/276178

Inventors:

Reinhard H. Witt - Wyncote PA
Robert M. Holland - Linfield PA

Assignee:

PQ Corporation - Berwyn PA

International Classification:

B07B 122

US Classification:

209303

Abstract:

A particle size classifier in which feed material composed of product and overs moves downwardly through a separator unit by the action of negative pressures created by a first air blower associated with the collection of product and a second air blower associated with the collection of overs. As the feed material moves downwardly, the product and the overs are separated with the product passing from within a screen unit to outside the screen unit and the screen unit preventing passage of the overs. Blowback air, applied to the screen unit from the outside cleans the cylindrical screen unit to permit continued passage of product through the screen unit.

Assignee:

Mobil Oil Corporation - New York NY

International Classification:

C07C 300
C07C 303

US Classification:

585415

Abstract:

The economics and thermal efficiency of an olefin-to-gasoline-conversion process utilizing catalyst beds is improved by separating the effluent product from the beds into a gas in a liquid phase, cooling the gas phase to form additional liquid and heat exchanging the liquid with the overhead gas from the separator.
