  • Patent number: 10640825
    Abstract: An analytical assembly within a unified device structure for integration into an analytical system. The analytical assembly is scalable and includes a plurality of analytical devices, each of which includes a reaction cell, an optical sensor, and at least one optical element positioned in optical communication with both the reaction cell and the sensor and which delivers optical signals from the cell to the sensor. Additional elements are optionally integrated into the analytical assembly. Methods for forming and operating the analytical system are also disclosed.

  • 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: 20190184166
    Abstract: Systems, methods, and devices for neuromodulation are described herein. For example, a method for modulating inflammatory processes of a subject is described. The method can include stimulating the subject's vagus nerve to activate an efferent pathway, and stimulating the subject's vagus nerve to inhibit neural activity. Pairing activation of the efferent pathway and inhibition of neural activity can enhance an anti-inflammatory response of the subject.
