Abstract: An apparatus for extended horizon scheduling that includes a time-sequence interpretation circuit, a target interpretation circuit, a horizon target analysis circuit, and a promotive action provisioning circuit. The time-sequence interpretation circuit interprets time-sequence data, the target interpretation circuit interprets target data, and the time-sequence trend analysis circuit extracts a trend from the time-sequence data. The horizon target analysis circuit: determines whether the extracted trend furthers or impedes a target defined, in part, by the target data, and responsive to a determination that the extracted trend impedes the target, generates a promotive action command value structured to trigger an adjustment to the time-sequence data. The adjustment is structured to mitigate the extracted trend from impeding the target. The promotive action provisioning circuit transmits the promotive action command value.

Abstract: An analysis instrument may perform analytical operations on an analyte that is combined with multiple reagents prior to being introduced into a flow cell. The instrument may include a nozzle sipper that aspirates reagents from a recipient, along with an analyte. The reagents may be directed to a volume and may be repeatedly moved into and out of the volume by cycling of a pump.

Abstract: An industrial information hub (IDH) serves as a single industrial ecosystem platform where multiple participants can deliver repeatable and standardized services relevant to their core competencies. The IIH system is centered around the development of an ecosystem that creates and delivers value to users—including industrial enterprises, OEMs, system integrators, vendors, etc.—through the aggregation of digital content and domain expertise. The IIH system serves as a trusted information broker between the ecosystem and the OT environments of plant facilities, and provides a platform for connecting assets, contextualizing asset data and providing secure access to the ecosystem. Additionally, the IIH system provides tools and support to OEMs and other subject matter experts, allowing those experts to enable their digital assets for use in the ecosystem. The IIH system reduces the cost and risks for digital transformation of industrial assets.
