  • UV curable transfix layer printing systems and methods for digital offset printing
    Patent number: 9193142
    Abstract: The disclosed systems and methods provide an ink-based digital printing system for printing high quality images on a wide latitude of image receiving media. The disclosed systems and methods employ a UV curable base (transfix) layer deposited on an intermediate image transfer member that is then at least partially cured prior to an aqueous ink being deposited on the base layer to form a digital image thereon. Once the images are formed on the base layer, a drying device is optionally used to reduce a water content of the aqueous ink images on the base layer prior to transfer of the images to an image receiving media substrate. At transfer, the images and at least a portion of the base layer are transferred to the image receiving media substrate, the images being sandwiched between the portion of the base layer and the image receiving media substrate.

    Abstract: A computer system for accessing remote content stored outside of a local network from within the local network comprises a relay proxy and a plurality of applications. The relay proxy receives a first request from a first application and a second request from a second application, the first and second requests identifying first and second remote content items respectively. The relay proxy forwards the first and second requests to a proxy server that manages network traffic entering and leaving the local network. The relay proxy receives responses to the first and second requests, with the response to the first request including the first remote content item and the response to the second request including the second remote content item. The relay proxy forwards the first and second remote content items to the first and second applications respectively.

  • SHARED VIRTUAL REALITY
    Publication number: 20150279081
    Abstract: An immersive three dimensional (3-D) virtual reality sharing system is disclosed. The system comprises a content controller configured to determine the physical locations of a reference point and boundary in a physical space and map them to a corresponding point and boundary in a virtual world. The physical location and orientation of a user device relative to the reference point and boundary are used to determine a corresponding location and orientation in the 3-D virtual world. A representation of a portion of the 3-D virtual world corresponding to the determined location and orientation is rendered at the user device. As the user device is moved in the physical world, a corresponding updated location in the 3-D virtual world is determined, and the rendered representation updated. Thus, the user device acts as a window into the 3-D virtual world.

  • Mapping positions of devices using audio
    Publication number: 20150219755
    Abstract: Disclosed are methods and systems for determining distance between two or more mobile devices utilizing a sound emitted from each device such as a chirp. Each device may determine or receive an indication of a time reference for each instance the device emits or detects a chirp. Utilizing the time reference data, the distance between the two or more devices may be determined assuming the sound travels at a constant speed of 340.29 m/s. Techniques for disambiguating orientation of the devices relative to one another rare also disclosed.

  • MAGNETIC MIXING FOR CONTINUOUS LATEX PREPARATION
    Publication number: 20150131405
    Abstract: A mixing process and system for mixing fluid such as a latex can include a first fluid and a second fluid that are combined to form, for example, a latex precursor. A plurality of magnetic particles are dispensed within the precursor. The precursor is dispensed within a mixing zone that may include a mixing tube. Two or more opposing electromagnets are activated out of phase (i.e., out of sync) to affect a travel path of the magnetic particles to form a turbulence within the precursor to provide an effective mixing of the precursor to form a material such as latex. The magnetic particles may be removed from the material, for example by filtering, or may remain within the material during use.
