Publication number: 20120071348Abstract: The present invention provides for rapid and large scale evaluation of expression of, or function of, nucleotide sequences in plants. The invention comprises three specific components which provide for fast and large scale evaluation of nucleotide sequences. The first component includes delivery in either a single event a library of different engineered vectors or a single engineered vector for a single target nucleotide sequence comprising sequences the function of which is desired to be known in plant cells. Surprisingly, applicants have discovered that, the introduction of multiple vectors to plant cells predominantly results in individual transgenic plants which contain only a single transformation event. The second feature of the invention involves a highly transformable, fast cycling and/or miniature size plant and the final step involves mass scale analysis of T0 plants for various phenotypes and plasmid rescue to identify the nucleotide sequence present in a particular phenotype.Type: ApplicationFiled: March 28, 2011Publication date: March 22, 2012Applicant: PIONEER HI BRED INTERNATIONAL INCInventors: MARC C.

Publication number: 20110109758Abstract: This disclosure describes techniques for improving functionalities of a back-end device, e.g., a video encoder, using parameters detected by a front-end device, e.g., a video camera. The techniques may involve detecting a scene change in a captured frame, based on one or more parameters of auto exposure (AE), auto white balance (AWB), and auto focus (AF) functions. If a scene change is detected in a captured frame, a video processing device, which may be a stand-alone device, or may be integrated into one of the front-end or back-end devices, provides an indication of the scene change. The video encoder interprets the signal as a trigger to encode the frame indicated as the frame where a scene change occurred as a reference I frame.Type: ApplicationFiled: May 5, 2010Publication date: May 12, 2011Applicant: QUALCOMM IncorporatedInventors: Liang Liang, Szepo R.
