    摘要: In a method for error correcting a data signal that is transmitted via a channel and contains data blocks with associated error checking information, the data signal is first equalized, with calculated soft-bit information. In a subsequent step, the error checking information is evaluated with respect to the data block. If the evaluation of the error checking information shows that a single bit error is present in one message bit, the single bit error is corrected only when a condition that is dependent on the soft-bit information is satisfied.

    摘要: A robot system includes a primary robot frame including a computerized control module providing control commands for the robot system, the primary robot frame including an outer perimeter. The robot system further includes a plurality of submodules, each submodule capable of being selectively docked with the primary robot frame, the submodules each providing different functionality to the robot system. The submodules, when docked with the primary robot frame, fit within the outer perimeter, enabling the robot system to operate in a closed mode, wherein all movement of the robot system is based upon the outer perimeter.

    摘要: The application provides a method for partitioning a watermark image with western language characters, comprising: partitioning a western language characters image along rows and columns to form a plurality of character image blocks; identifying valid character image blocks from the formed character image blocks; counting sizes of the valid character image blocks to determine if the image corresponds to a document with a large font size or a document with a small font size; dividing words in the image into a plurality of groups, wherein each divided group in the document with large font size has different numbers of words from that with small font size; and dividing equally the divided word groups into multiple portions corresponding to watermark image blocks. The application further provides a device for partitioning a watermark image with western language characters. The operability of watermark embedding process can be ensured through the above technical solution.
