  • Patent number: 10558191
    Abstract: Systems and methods are provided to facilitate receipt of tag requests from one or more interfaces, based upon which a single tagset is compiled at a controller comprising all the requested tags for a given update rate, whereupon the single compiled tagset is subsequently forwarded to the one or more interfaces. A controller generates a superset of tags associated with an industrial process. Each interface can request a copy of the superset, from which the required tags are selected. The controller receives the requested tags from all of the interfaces and combines the requested tags into a single tagset, for a given update rate, comprising the various parameters associated with the tags. At the selected update rate, the tagset is forwarded to the interfaces. A masterset can be utilized to identify the sequence of tags in a tagset and check code can ensure continuity of the tags in the tagset.

  • Patent number: 10472735
    Abstract: There is herein described a method of making a single crystal wavelength conversion element from a polycrystalline wavelength conversion element, a single crystal wavelength conversion element, and a light source containing same. By making the single crystal wavelength conversion element from a polycrystalline wavelength conversion element, the method provides greater flexibility in creating single crystal wavelength conversion elements as compared to melt grown methods for forming single crystals. Advantages may include higher activator contents, forming more complex shapes without machining, providing a wider range of possible activator gradients and higher growth rates at lower temperatures.

  • Publication number: 20190258954
    Abstract: In general, embodiments of the present invention provide systems, methods and computer readable media for automated dynamic data quality assessment. One aspect of the subject matter described in this specification includes the actions of receiving a data quality job including a new data sample; and, if the new data sample is determined to be added to a reservoir of data samples, sending a quality verification request to an oracle; receiving a new data sample quality estimate from the oracle; and adding the new data sample and estimate to the reservoir. A second aspect of the subject matter includes the actions of receiving, from a predictive model, a judgment associated with a new data sample; analyzing the new data sample based in part on the judgment to determine whether to send a new data sample quality verification request to an oracle; and, if a new data sample quality estimate is received from the oracle, determining whether to add the new data sample and the judgment to the reservoir.
