This patent was taken from the Google Patents database. The OCR that Google originates has been edited.
There are 3 formats available: .pdf (original), .txt (clean text), and .brf (braille file). .brf is a file format used by the blind. See the "all files HTTP" link to access all three.
During the editing process, a diligent attempt has been made to correctly discern every reference character set forth in the patent, and the majority by far are correct. However, because the OCR process is not entirely accurate, there may be some reference characters that are inconsistent or incorrect.
In the .txt and .brf formats of these patents, the assignee is not always identified.
