Publication number: 20150092370Abstract: A method for applying a protective coating to selected portions of a substrate is disclosed. The method includes applying a mask to or forming a mask on at least one portion of the substrate that is not to be covered with the protective coating. The mask may be selectively formed by applying a flowable material to the substrate. Alternatively, the mask may be formed from a preformed film. With the mask in place, the protective coating may be applied to the substrate and the mask. A portion of the protective coating that overlies the mask may be delineated from other portions of the protective coating; for example, by cutting, weakening or removing material from the protective coating at locations at or adjacent to the perimeter of the mask. The portion of the protective coating that overlies the mask, and the mask, may then be removed from the substrate.Type: ApplicationFiled: December 10, 2014Publication date: April 2, 2015Inventors: David James Astle, Tyler Christensen Child, Vimal Kumar Kasagani, Cameron LaMar Loose, Blake LeRoy Stevens, Max Ernest Sorenson

Publication number: 20140355429Abstract: A dynamic spectrum arbitrage (DSA) system may include a dynamic spectrum policy controller (DPC) and a dynamic spectrum controller (DSC) that together dynamically manage the allocation and use of resources (e.g., spectrum resources) across different networks. A dynamic spectrum arbitrage application part (DSAAP) protocol/component/module may allow, facilitate, support, or augment communications between the DSC and DPC so as to improve the efficiency and speed of the DSA system. The DSAAP may allow the DPC and/or DSC components to better pool resources across the different networks, better monitor traffic and resource usage in the various networks, to more efficiently communicate bids and bidding information, to quickly and efficiently register and deregister components, and better perform backoff operations.Type: ApplicationFiled: May 26, 2014Publication date: December 4, 2014Applicant: Rivada Networks, LLCInventors: Clint Smith, Nageswara Rao Deekshitha Devisetti, Samuel Smith, Purnima Surampudi, Nithin Nellikunnu, Sony Mohanty, Geetha C.

Publication number: 20140358759Abstract: A dynamic spectrum arbitrage (DSA) system may include a dynamic spectrum policy controller (DPC) and a dynamic spectrum controller (DSC) that together dynamically manage the allocation and use of resources (e.g., spectrum resources) across different networks. The DSC and DPC may be configured communicate using a DSAAP protocol, component, or communication message. For example, the DSC may be configured to receive a list of resources that are available for bidding via a communication link to DPC using a DSAAP protocol, generate a bid request message to bid on a resource in the received list of resources, and send the bid request message to the DPC. The DPC may receive the bid request message from the DSC, determine whether the bid request message is valid, determine whether the DSC is a winner bidder, and sending a bid won message to the DSC via the communication link using a DSAAP protocol.Type: ApplicationFiled: May 26, 2014Publication date: December 4, 2014Applicant: Rivada Networks, LLCInventors: Clint Smith, Nageswara Rao Deekshitha Devisetti, Samuel Smith, Purnima Surampudi, Nithin Nellikunnu, Sony Mohanty, Geetha C.
