Abstract: An activity smoothener circuit is provided to control rates of change in processing activity to limit di/dt in activity areas of an IC to mitigate voltage droops or overshoots. Controlling the rate of change of activity prevents or reduces instances of a di/dt exceeding a programmed maximum that is based on physical limits of the IC and/or a package. In examples, the activity smoothener circuit includes a hierarchy of smoothening circuits controlling activity in areas down to individual circuit blocks (tiles) including execution circuits. An indication of a desired level of activity is provided to a parent smoothening circuit and the parent smoothening circuit responds with indications of actual activity allowed to occur. At each level of hierarchy, the activity smoothener circuit may use algorithms to generate indications of actual activity based on indications of desired activity and di/dt limits. Di/dt limits and current minimums and maximums are controlled.

Abstract: A sample ratio mismatch (SRM) analyzer receives data from an online controlled experiment (OCE) and provides information to help determine a root cause of an SRM. The SRM analyzer may identify one or more segments in the data that include an SRM and may determine whether a triggered scorecard of the OCE includes an SRM. The data may include one or more scorecards. The SRM analyzer may determine whether each scorecard has an SRM. The SRM analyzer may test a difference in proportion of users assigned to treatment between a last scorecard without an SRM and a first scorecard with an SRM. If the difference in proportion is statistically meaningful, the SRM analyzer may determine that the SRM arose after the last scorecard. If the difference in proportions is not statistically meaningful, the SRM analyzer may determine that the SRM existed from a beginning of the OCE.

Abstract: A sunshade device and management system for mitigating the effects of climate change to help reduce the risk of extinction of plants, animals, and humans. The sunshade device has a canopy, which will collapse when lifted into the atmosphere by lifting devices, and open when the lifting devices are turned down or off, to provide shade. The canopy is preferably formed of a flexible lightweight solar panel film containing solar cells, which charge a battery power system which operates electrically powered propeller-driven lifting devices attached to a central portion of the canopy. The sunshade management device controls the lifting devices to manage the sunshade device elevation, angle and geolocation. The sunshade management device is provided with artificial intelligence and machine learning whereby it is able to make determinations regarding sunshade device takeoff and shutdown, and positioning of the elevation and angle of the canopy relative to the ground below, to maximize the shade effects of the canopy.

In response to detecting a load imbalance based on the first performance metric and the second performance metric, the technique further includes moving the NAS file server from the first storage node to the second storage node and hosting the set of volumes that belong to the NAS file server from the second storage node.

Each identified relevant instance of the content is analyzed based on the one or more classifiers of the domain-specific template to identify one or more additional relevant instances of the content. The one or more identified additional relevant instances of the content are added to the contextual protocol package.

Abstract: Methods and systems are described for maintaining hygienic conditions in automatic teller machines by detecting whether or not a user is not in compliance with a hygienic standard. If a user is not in compliance, then the automatic teller machine may execute a hygienic action to cleanse the automatic teller machine. For example, the hygienic action may comprise automatically cleansing the automatic teller machine, disabling the automatic teller machine from service, transmitting a sanitation service request to an automatic teller machine provide, and/or initiating an alternative control scheme (e.g., voice controls, gesture-based controls, etc.) for the automatic teller machine.
