  • Patent number: 8995793
    Abstract: In some approaches, super-resolution of static and moving objects can be performed. Results of moving object super-resolution may be improved by means of performing image co-registration. The quality of images of moving objects in an automated form may be improved. A sequence of images may be processed wherein objects can be detected and tracked in succeeding frames. A small region around a tracked object may be extracted in each frame. These regions may be co-registered to each other using frequency domain techniques. A set of co-registered images may be used to perform super-resolution of the tracked object. Also described are image processing systems and articles of manufacture having a machine readable storage medium and executable program instructions.

  • Patent number: 8946378
    Abstract: Conducting polymer systems for hole injection or transport layer applications including a composition comprising: a water soluble or water dispersible regioregular polythiophene comprising (i) at least one organic substituent, and (ii) at least one sulfonate substituent comprising sulfonate sulfur bonding directly to the polythiophene backbone. The polythiophene can be water soluble, water dispersible, or water swellable. They can be self-doped. The organic substituent can be an alkoxy substituent, or an alkyl substituent. OLED, PLED, SMOLED, PV, and ESD applications can be used.

  • Publication number: 20070065590
    Abstract: Latent doping is provided wherein a conducting polymer is mixed with a dopant in solution without the doping reaction occurring unless solvent is removed. Regioregular polythiophenes are a particularly important embodiment. A composition comprising (i) at least one polymer comprising conjugation in the polymer backbone, (ii) at least one dopant for the polymer, (iii) at least one solvent for the polymer and latent dopant, wherein the polymer, the latent dopant, and the solvent are formulated so that the latent dopant does not substantially dope the polymer when formulated, but does substantially react with the polymer when the solvent is removed. Formulation of the composition can comprise adjusting the order of mixing, the amounts of the components, and the temperature. Methods of formulating the compositions and methods of using the compositions are also provided. OLED, PLED, photovoltaic, and other organic electronic devices can be fabricated.
