Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

 Appl.No 11510273 Applicant NOVELO MANUEL R G Inventor Novelo Manuel Rafael Gutierrez

In order to obtain three-dimensional images from a digital video stream, certain modifications have been made to the current MPEG2 coders; software and hardware changes in different parts of the coding process are made. In effect, the structures and the video_sequence of the video data stream are modified to include the necessary flags to identify at the bit level the TDVision® technology image type.

Changes have been made to current MPEG2 coders by making software and hardware changes in different parts of the coding process with the aim of obtaining three-dimensional images in a digital video stream. The video sequence structures of the video data stream are modified in order to include the necessary flags that identify the type of TDVision® technology image at bit level. Software modifications are made in the processes relating to the heading of the video sequence, modification of the identification flags, modification of data fields, modification of image fields. An electronic comparison between left channel and right channel images is carried out in the hardware. The difference is processed as a B-type image, namely an error correction is carried out. The result is stored in the buffer memory with the TDVision® technology identifier. During information coding, a DSP is used, wherein said DSP performs the processes of predicting, comparing, quantifying and applies the DCT function in order to form the compacted MPEG2-compatible video stream.

 Appl.No 201210499295.2 Applicant ZTE CORPORATION. Inventor GUO YONG
The invention discloses a method for sending user data in a passive optical network (PON). The method comprises the following steps: a transmission convergence (TC) layer of a sending end encapsulates user data into a multi-frame; and a physical medium dependent (PMD) layer of the sending end performs frequency division multiplexing (FDM) modulation on the multi-frame and sends the FDM modulated multi-frame to a receiving end through an optical fiber. The invention further discloses a method for receiving user data in a PON, a system for sending and receiving user data in a PON, and a piece of equipment. According to the scheme of the invention, user data transmission of any granularity can be realized.
