  • Patent number: 10626457
    Abstract: Arrays of integrated optical devices and their methods for production are provided. The devices include an integrated bandpass filter layer that comprises at least two multi-cavity filter elements with different central bandpass wavelengths. The device arrays are useful in the analysis of highly multiplexed optical reactions in large numbers at high densities, including biochemical reactions, such as nucleic acid sequencing reactions. The devices provide for the efficient and reliable coupling of optical excitation energy from an optical source to the optical reactions. Optical signals emitted from the reactions can thus be measured with high sensitivity and discrimination. The device arrays are well suited for miniaturization and high throughput.

  • Patent number: 10534795
    Abstract: Examples describe mechanisms for maintaining consistent subscriber data on geo-redundant subscriber databases. In an example, a request to perform an operation related to subscriber data may be received on a subscriber database, wherein the subscriber database may be a geo-redundant deployment of a separate subscriber database. The connectivity status of a synchronization link between the subscriber database and the separate subscriber database may be determined. In response to the determination that the connectivity status of the synchronization link between the subscriber database and the separate subscriber database is disconnected, the request to perform the operation related to the subscriber data on the subscriber database may be denied.

  • Patent number: 10531272
    Abstract: A mechanism for consistent public land mobile network (PLMN) specific supplementary services across different PLMNs or different service areas/regions of a PLMN is provided. A visited PLMN in which a subscriber unit is receiving or is attempting to receive service may be identified. Home PLMN specific supplementary services provisioned for the subscriber unit may be mapped to visited PLMN specific supplementary service codes set forth in the visited PLMN. These visited PLMN specific supplementary service codes may be used to replace the home PLMN specific supplementary service codes and transmitted to the visited PLMN using outgoing Mobile Application Part messages.

  • Publication number: 20190239063
    Abstract: In some examples, a system includes a storage to store a repository of user information, and a processor to receive, from a requester device, a request for a first information element relating to a user entity, and in response to a determination that the requester device supports a feature that enables the requester device to request multiple different information elements relating to the user entity in one request, send, in a response message that is responsive to the received request, the first information element and a second information element, the second information element not indicated as being requested by the received request.

  • Patent number: 9754836
    Abstract: Disclosed are packaging methods for the fabrication of analytical device packages and fabricated analytical device packages. The methods include providing a sensor wafer and mounting individual plates or a plate wafer on the sensor wafer. The sensor wafer includes sensor chips with aperture regions and is treated with selective depositions, either prior to or during the fabrication of the analytical device packages, to produce different surface characteristics at different portions of the aperture regions. Before dicing the sensor wafer, openings of the individual plates or the plate wafer are covered by a protective layer to protect surface characteristics at different portions of the aperture regions. A fabricated analytical device package includes a sensor chip with different surface characteristics, a plate, a packaging substrate and an optional cover.

  • Patent number: 9689800
    Abstract: Processes for making high multiplex arrays for use in analyzing discrete reactions at ultra high multiplex with reduced optical noise, and increased system flexibility. The high multiplex arrays include substrates having integrated optical components that increase multiplex capability by one or more of increasing density of reaction regions, improving transmission of light to or collection of light from discrete reactions regions. Integrated optical components include reflective optical elements which re-direct illumination light and light emitted from the discrete regions to more efficiently collect emitted light. Particularly preferred applications include single molecule reaction analysis, such as polymerase mediated template dependent nucleic acid synthesis and sequence determination.
