  • Patent number: 10545492
    Abstract: An industrial data indexing system facilitates discovery and indexing of plant-wide data residing on multiple different data platforms. The indexing system automatically inventories industrial devices and other data sources located throughout a plant, and identifies available data items on each data source. The indexing system indexes the discovered data items in a federated data model that can subsequently be searched to locate data items or tags of interest. The federated data model records references to data items found on different types of data sources, including but not limited to industrial controller programs, human-machine interface applications, data historians, device documentation stores, inventory tracking systems, and other such data sources. The search system also caches selected portions of the data model to a user's personal device to allow these portion of the model to be accessed locally on the user's device without being online with the higher level indexing system.

  • Patent number: 10313281
    Abstract: An automated industrial notification platform creates a link between a given industrial asset and one or more people or support entities qualified to provide support for the asset. An industrial device or machine stores electronic expert tag information that records and catalogs one or more support people or entities to be notified in response to detection of various types of performance or maintenance issues. The tag can include the experts' identities, contact information, roles relative to the industrial asset, event priorities, and other relevant information. Since the tag is stored in a memory location of the industrial asset, the tag travels with the asset so that experts are globally associated with the asset regardless of the asset's location. Notification components integrated with the industrial asset detect conditions that may require expert assistance, and send an automated notification to one or more experts identified by the tag information.

  • Patent number: 8754625
    Abstract: A converter according to one embodiment converts an AC voltage to a regulated output current provided to a DC load of a Z-type configuration. A filter capacitor is provided to average current flowing through the load. The converter includes a rectifier network for rectifying the AC voltage and for providing a rectified voltage, and a smoothing capacitor for smoothing the rectified voltage. The converter includes a hysteretic current mode controller which controls a switching transistor based on sensed voltage and sensed current provided through an inductor coupled in series with the load. The transistor is turned on when current reaches a low valley level and is turned off when the current reaches a peak level. Operation toggles in this manner while a sensed voltage is above a predetermined level. A valley fill network may be provided to keep sensed voltage from falling below the predetermined minimum level.

  • Patent number: 8569963
    Abstract: A converter system including a cascade boost converter and inverting buck converter and controller for converting a rectified AC voltage to a DC output current. The system uses inductors and is configured to use a common reference voltage. The controller is configured to control switching of the converters in an independent manner to decouple operation from each other. For example, control pulses for the boost converter may be wider than pulses for the buck converter. The controller may control the boost converter based on constant on-time control and may control the inverting buck converter based on peak current control. The rectified AC voltage may be an AC conductive angle modulated voltage, where the controller may inhibit switching of the inverted buck converter at a dimming frequency having a duty cycle based on a phase angle of the AC conductive angle modulated voltage.
