  • Patent number: 9032463
    Abstract: A method and apparatus for providing content in a broadcast system is provided. Upon receipt of a request for synchronization from a mobile terminal, a set-top box creates a recommended content list based on user information received from the mobile terminal and delivers the recommended content list to the mobile terminal. The set-top box receives from the mobile terminal a content list, selected from the recommended content list and included in a Personal Information Management System (PIMS) updated using the recommended content list. The set-top box determines whether a user of the mobile terminal intends to view content from the received content list at a start time of the content. Upon receipt of view acceptance information from the mobile terminal, the set-top box sends a request for the content to a service provider at the start time, receives the requested content from the service provider, and provides the received content to the mobile terminal.

  • Patent number: 8922857
    Abstract: Optical solenoid beams, diffractionless solutions of the Helmholtz equation whose diffraction -limited in-plane intensity peak spirals around the optical axis, and whose wavefronts carry an independent helical pitch. The solenoid beams have the noteworthy property of being able to exert forces on illuminated objects that are directed opposite to the direction of the light's propagation. Optical solenoid beams therefore act as true tractor beams that are capable of transporting material back toward their source.

  • Publication number: 20140333935
    Abstract: In-line holography to create images of a specimen, such as one or more particles dispersed in a transparent medium. Analyzing these images with results from light scattering theory yields the particles' sizes with nanometer resolution, their refractive indexes to within one part in a thousand, and their three dimensional positions with nanometer resolution. This procedure can rapidly and directly characterize mechanical, optical and chemical properties of the specimen and its medium.

  • Patent number: 8331019
    Abstract: A method and system for performing three-dimensional holographic microscopy of an optically trapped one dimensional structure. The method and system use an inverted optical microscope, a laser source which generates a trapping laser beam wherein the laser beam is focused by an objective lens into a plurality of optical traps. The method and system also use a collimated laser at an imaging wavelength to illuminate the structure created by the optical traps. Imaging light scattered by the optically tapped structure forms normalized intensity holograms that are imaged by a video camera and analyzed by optical formalisms to determine light field to reconstruct 3-D images for analysis and evaluation.
