| 20080297093 | Systems and Methods for Reduction of Cross Coupling in Proximate Signal Lines - Various systems and methods for reducing cross coupling in proximate signals are disclosed. As one example, a system for reducing cross-coupling in adjacent signals that includes an active slew rate limiter circuit is disclosed. The active slew rate limiter circuit is operable to receive an input signal, and to provide an output signal based on the input signal with a controlled slew rate. In some cases, such systems may be included within a storage device that includes a read head. In such cases, the systems may operate to assure a substantially constant power dissipation within the read head. | 12-04-2008 |

| 20100172417 | MOTION ESTIMATION TECHNIQUE FOR DIGITAL VIDEO ENCODING APPLICATIONS - The present invention provides an improved motion estimation encoder for digital video encoding applications. In one example embodiment, the improved encoder receives a raw image in the form of a current frame and estimates the macroblock motion vector with respect to a reference frame. The encoder then performs an initial local search around an initial motion vector candidate derived from spatio-temporal neighboring macroblock parameters. The encoder then compares the user-defined complexity scalable sum of absolute difference between the original and the associated reference macroblock against an adaptive threshold value for motion estimation convergence. The encoder introduces a global full search around a candidate from a coarser level, in case an initial local search fails. The encoder then selects an inter encoding mode for coding the current macroblock, when the first local search is successful, otherwise the encoder selects the inter or intra encoding mode for encoding the current macroblock by comparing variances of the original and difference macroblocks. | 07-08-2010 |

| 20130137446 | DYNAMIC REORGANIZATION OF CELL STRUCTURES IN WIRELESS NETWORKS - Dynamic reorganization of cell structures in wireless networks. The present invention relates to wireless communications and, more particularly, to energy usage of wireless equipments in wireless communications. Currently there are mechanisms in use that can selectively turn of carriers in a BTS depending on the traffic load. But due to the fixed costs of operating the base station even when there are no active users, turning off entire BTS will give more energy savings than simply reducing capacity by turning off carriers at low load. Embodiments herein detect a change in demand on the network and re-organize the cellular network by selectively turning off BTSs and appropriately increasing the coverage area of other BTSs, and arrive at a configuration that optimizes the energy consumption of the cellular network as a whole. | 05-30-2013 |
