20100220197Assisted Video Creation Utilizing a Camera - The invention allows for persons to create motion photo videos or MPVs from photographs, video segments, personal narratives or animation by use of templates. Templates are created for specific songs, may be created or further modified by any person. MPVs are novel because they very quickly and inexpensively enable users to select a song and accompanying pre-made template and create a high-quality synchronized custom music video using their own hand-selected visual material. These custom videos can be shared by users with friends or can be published on the Internet and can be easily modified by swapping visual material or updating templates. Additionally, image capture devices may be employed to assist the user in capture, composition, and selection of images to be placed in pre-defined template bins, resulting in instant high-quality director-assisted video creation.09-02-2010
20100223128Software-based Method for Assisted Video Creation - The invention allows for a first set of persons to create and modify templates that contain visual effects, synchronization information, and possibly director assistance. These templates are utilized by a second set of persons to generate personalized motion photo videos from photographs, video segments, personal narratives or animation. Motion photo videos are a novel because they very quickly and inexpensively allow (1) persons to create and modify templates which are synchronized to music and may be easily populated with content by others, and (2) persons to select a song and associated pre-made template and create a high-quality synchronized custom video using hand-selected visual material to populate the template with included direction and without any required editing. Populated material in template can be further modified by additional persons instantly generate new, modified motion photo videos.09-02-2010

20090029866Libraries of oligomers labeled with different tags - A method of making a set of labelled compounds by the use of a preferably particulate support, comprises dividing the support into lots, performing a different chemical reaction on each lot of the support, e.g. to couple a chemical moiety to that lot of the support, tagging a fraction of each lot of the support with a different label, and combining the said lots of the support. The steps are repeated several times, preferably to build up oligomer molecules carrying labels which identify the nature and position of a monomer unit of the oligomer, and which are releasable from the support. Preferred labels, which are releasable from the compounds by cleavage to provide charged groups for analysis by mass spectrometry, are groups of the trityl (trimethylphenyl) family. Also claimed are libraries of these labels and their use in assays and nucleic acid analysis methods.01-29-2009

The data processor includes an interleaver memory which reads-in the predetermined number of data symbols for mapping onto the OFDM sub-carrier signals. The interleaver memory reads-out the data symbols on to the OFDM sub-carriers to effect the mapping, the read-out being in a different order than the read-in, the order being determined from a set of addresses, with the effect that the data symbols are interleaved on to the sub-carrier signals. The set of addresses are generated from an address generator which comprises a linear feedback shift register and a permutation circuit.
