Publication number: 20130223012Abstract: Heat dissipation in vertically arrayed host device configurations can be improved through inclusion of heat sinks having split-stream fin architectures. The split-stream fin architecture includes two or more sets of angled fins separated by a central conduit, which allows for more efficient inflow and/or expulsion of convection cooling air over the heat sink. The split-stream fin arrangement may include inwardly angled fins in order to draw convection cooling air inwards from horizontal inlets, in which case warm exhaust is expelled through the central conduit. Conversely, the split-stream fin arrangement may include outwardly angled fins, which draw convection cooling air from the central conduit, and expel warm air through horizontal exhausts. The split-stream fin arrangements function well when host devices are configured horizontally, which allows for more flexible host device configurations.Type: ApplicationFiled: February 23, 2013Publication date: August 29, 2013Applicant: FUTUREWEI TECHNOLOGIES, INC.Inventor: FutureWei Technologies, Inc.

Publication number: 20130188712Abstract: Error drift during compressed domain watermarking can be reduced by embedding watermarking symbols in macroblocks that have relatively low influence on pixel values of other macroblocks during video decompression. This influence may be quantified using compression influence values (CIVs), which may be computed/assigned based on prediction dependency relationships amongst the various macroblocks in a sequence of frames. To wit, high CIVs are assigned to macroblocks that heavily influence the pixel values of other macroblocks during intra-frame/inter-frame prediction, while low CIVs are assigned to macroblocks that have little influence over the pixel values of other macroblocks. Macroblocks having the lowest CIVs may be selected for embedding compressed domain watermarking bits/symbols. Alternatively, macroblocks having high CIVs may be excluded from a pool of candidate macroblocks that are eligible for carrying embedded compressed domain watermarking bits/symbols.Type: ApplicationFiled: January 24, 2013Publication date: July 25, 2013Applicant: FUTUREWEI TECHNOLOGIES, INC.Inventor: FutureWei Technologies, Inc.
