  • Patent number: 10853776
    Abstract: A cloud wallet system may receive an indication from a third party system that a user has checked-in at a merchant. The cloud wallet system then determines whether the merchant has an account with the cloud wallet system so that a point-of-sale (POS) purchase can be processed via the user check-in. If the merchant has an account with the cloud wallet system, a user profile corresponding to the user is sent to the merchant and a point-of-sale transaction based on a third party user check-in may be processed by the merchant through the cloud wallet system.

  • Patent number: 8128242
    Abstract: A method of manufacturing a semiconductor device able to reduce the number of manufacturing steps and attain the rationalization of a manufacturing line is disclosed. The semiconductor device is a high-frequency module assembled by mounting chip parts (22) and semiconductor pellets (21) onto each of wiring substrates (2) formed on a matrix substrate (27) after inspection. A defect mark (2e) is affixed to a wiring substrate (2) as a block judged to be defective in the inspection of the matrix substrate (27), then in a series of subsequent assembling steps the defect mark (e) is recognized and the assembling work for the wiring substrate (2) with the defect mark (2e) thereon is omitted to attain the rationalization of a manufacturing line.

  • Patent number: 7324282
    Abstract: The present invention relates to a system of applying optical gradient forces to form a plurality of optical traps to manipulate small particles. The system includes a light source for generating a focused beam of light which is directed along an optical axis though a phase patterning optical element having a variable optical surface and which has a virtual lens encoded thereon. The optical element produces a plurality of beamlets that are coverged at a position between the optical element and a single transfer lens, and directed through the transfer lens to overlap at the back aperture of a focusing lens. The focusing lens coverges the beamlets to form a plurality of optical traps in the working focal region where particles to be examined, manipulated, or measured, are disposed.

  • Publication number: 20070084993
    Abstract: A method and system for generating modulated optical vortices. Optical vortices can be used for a variety of applications, such as applying controlled torque or controlled force patterns to objects from a few nanometers to hundreds of micrometers in size. Numerous optical modes of optical vortices can be created to meet virtually any desired need in manipulating of objects. Furthermore, one can modify the wavefront of a beam of light in a specific way to create a new type of optical trap useful for manipulating mesoscopic materials. When the modified beam is brought to a focus, the resulting optical trap exerts forces transverse to the optical axis that can be used to transport mesoscopic matter such as nanoclusters, colloidal particles, and biological cells.

  • Publication number: 20060240591
    Abstract: A system and method for manipulating and processing nanowires in solution with arrays of holographic optical traps. The system and method of the present invention is capable of creating hundreds of individually controlled optical traps with the ability to manipulate objects in three dimensions. Individual nanowires with cross-sections as small as 20 nm and lengths exceeding 20 ?m are capable of being isolated, translated, rotated and deposited onto a substrate with holographic optical trap arrays under conditions where single traps have no discernible influence. Spatially localized photothermal and photochemical processes induced by the well-focused traps can also be used to melt localized domains on individual nanowires and to fuse nanowire junctions.

  • Publication number: 20060163463
    Abstract: A method and apparatus for selecting a specific fraction from a heterogeneous fluid-borne sample using optical gradient forces in a microfluidic or fluidic system are presented. Samples may range in size from a few nanometers to at least tens of micrometers, may be dispersed in any fluid medium, and may be sorted on the basis of size, shape, optical characteristics, charge, and other physical properties. The selection process involves passive transport through optical intensity field driven by flowing fluid, and so offers several advantages over competing techniques. These include continuous rather than batch-mode operation, continuous and dynamic tunability, operation over a wide range of samples, compactness, and low cost.

  • Publication number: 20060056807
    Abstract: Systems and methods for encoding information in the topology of superpositions of helical modes of light, and retrieving information from each of the superposed modes individually or in parallel. These methods can be applied to beams of light that already carry information through other channels, such as amplitude modulation or wavelength dispersive multiplexing, enabling such beams to be multiplexed and subsequently demultiplexed. The systems and methods of the present invention increase the number of data channels carried by a factor of the number of superposed helical modes.
