  • Microrna molecules
    Patent number: 7838662
    Abstract: In Caenorhabditis elegans, lin-4 and let-7 enclode 22- and 21-nucleotide RNAs, respectively, that function as key regulators of developmental timing. Because the appearance of these short RNAs is regulated during development, they are also referred to as “small temporal RNAs” (stRNAs). We show that many more 21- and 22-nt expressed RNAs, termed microRNAs, (miRNAs), exist in invertebrates and vertebrates, and that some of these novel RNAs, similar to let-7 stRAN, are also highly conserved. This suggests that sequence-specific post-transcriptional regulatory mechanisms mediated by small RNAs are more general than previously appreciated.

  • Device for homogenizing radiation by means of irregular microlens arrays
    Patent number: 7839573
    Abstract: A device for the homogenization of radiation, preferably light, using chirped microlens arrays (cMLA) from the established regular microlens arrays (rMLA), chirped microlens arrays are an arrangement of non-identical lenses in one array. Non-identical means that the lens parameters of the lenses of the array, such as e.g. the radius of curvature, the free diameter, vertex position, and others, can vary from lens to lens or cell to cell. The parameters of each lens or cell can be determined by functions (analytically, numerically), the functions preferably being dependent upon the position of the cell or the lens in the array.

    Abstract: An electro-optic display comprises, in order, a backplane comprising a plurality of pixel electrodes; a layer of a solid electro-optic medium; a main adhesive layer; and at least one of a light-transmissive protective layer and a light-transmissive electrically-conductive layer. The electro-optic layer may be in direct contact with the backplane or separated therefrom by a thin auxiliary layer of adhesive. The main adhesive layer may be colored to provide a color filter array. An inverted front plane laminate useful in forming such a display comprises the same layers except that the backplane is replaced by a release sheet. The display combines good low temperature performance and good resolution at higher temperatures.
