US Patent:

6937669, Aug 30, 2005

Filed:

Dec 3, 2002

Appl. No.:

10/308831

Inventors:

Andrew T. Tomerlin - Coral Springs FL, US
Asad Ullah Aman - Roselle IL, US
Robert V. Stephens - Bartlett IL, US

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04L025/49

US Classification:

375297, 4551143

Abstract:

A predistortion linear power amplifier utilizes several predistortion computation engines to receive a first carrier signal. The predistortion computation engines also receive input from a predistortion algorithm engine. The predistortion algorithm engine receives its data from a predistortion amplifier sensor that monitors the operating characteristics of the amplifier and also from a feedback control circuit that provides frequency correlated input and feedback data. The processed data from the predistortion algorithm engine is then input into the predistortion computation engine along with the carrier signal. An output combiner circuit takes the output of each predistortion computation engine and generates a single correction estimate, which is then input into the nonlinear amplifier for producing a substantially linear output signal.

Abstract:

A laser-designated target simulator for testing laser-guided munitions and in particular the laser-seeking heads thereof. In one embodiment, the simulator includes: (1) a laser light source configured to provide laser light, (2) a waveguide configured to receive the laser light via an end thereof, (3) a baffle structure having a plurality of cavities associated therewith and (4) an actuator coupled to the laser light source and the end and configured to establish a distance therebetween, an intensity of the laser light entering the end being a function of the distance and a number of cavities interposing the laser light source and the end.

International Classification:

A63B 53/04

US Classification:

473345

Abstract:

A hollow golf club incorporating a stress reducing feature having a shield serving to lessen the visual impact of the stress reducing feature, reduce the likelihood of debris from entering the stress reducing feature, and reduce the likelihood of damage to the stress reducing feature, while adding rigidity to a portion of the stress reducing feature and still allowing the stress reducing feature to selectively increase the deflection of the face.

International Classification:

G06F 1900

US Classification:

702 16

Abstract:

A method of seismic analysis is disclosed for identifying subterranean features that in one embodiment uses a coherence analysis for improved seismic data interpretation such as improved accuracy of variables for use in velocity models. The method may be used while analyzing seismic data to produce an earth model wherein the analysis is preferably applied at each level for the model. In another embodiment of the present invention, the coherence analysis is applied as a function of the seismic processing sequence to improve the variables associated therewith. With respect to a subterranean location of interest, azimuth ordered gathers may be used to identify subterranean features such as fault/fracture patterns. In another embodiment, offset ordered coherence analysis is used to form an optimum stack at the subterranean location of interest. In another embodiment of the invention, factors such as P, S, G, and fluid factor are derived from coherence data from which instantaneous envelope gathers are computed and divided into angle gathers.
