20150200455 | ANTENNA FEED - An antenna feed and methods are disclosed. The antenna feed is for generating signals for an antenna array for transmitting a transmission beam having one of a plurality of different tilt angles, the antenna feed comprises: a digital signal processor operable to receive an input broadband signal and to generate, in response to a requested tilt angle, a plurality N of output broadband signals, each having an associated phase and amplitude; a plurality N of transmission signal generators, each operable to receive one of the plurality N of output broadband signals and to generate a corresponding plurality N of first RF signals; a feed network operable to receive the plurality N of first RF signals and to generate a plurality P of second RF signals, each of the plurality P of second RF signals having an associated amplitude and phase, the plurality P of second RF signals being used to generate a plurality M of third RF signals, where P is no less than M, each third RF signal having an associated phase and amplitude for supplying to a corresponding antenna of a plurality M of antennas of the antenna array to transmit the transmission beam with the requested tilt angle. By increasing the number of signals generated within the feed network, which are utilized to generate the third RF signals for supplying to the antenna, the range of possible tilt angles is increased as are the possible range of beam patterns in order to satisfy the coverage and capacity requirements. | 07-16-2015 |

20150071037 | METHOD FOR DETERMINING A LITHOLOGY MAP - The present invention relates to a method for determining a lithology map. The method comprises receiving a geophysical attribute image comprising a plurality of points associated with geophysical attribute value, and receiving first information data representing a plurality of zones in the image, each point of the image being contained in a zone. For at least one point of the image, computing a uniform value associated with said point based on the geophysical attribute value and distributions values of the geophysical attribute values. The method further comprises receiving second information data representing geological probability value for a plurality of facies associated with the points of the image, and for at least one point of the image, determining a facies in the plurality facies based on the computed uniform value and the geological probabilities associated with said point. | 03-12-2015 |
