Abstract: A method for a redox flow battery may include, interrupting cycling of the redox flow battery, including charging the redox flow battery to a threshold charge condition, draining positive and negative electrolyte from the redox flow battery, circulating a wash solution through the redox flow battery, and returning the positive and negative electrolyte to the redox flow battery, and resuming cycling of the redox flow battery. In this way, contamination of the redox flow battery system can be reduced, thereby prolonging the life and increasing performance of the redox flow battery system.

Abstract: Systems and methods are provided for evaluating performance of a heat exchanger, such as a condenser, using rules-based logic. A plurality of sensors can measure various operating properties of the heat exchanger and transmit corresponding measurement information to a controller. The controller can (i) evaluate the measurement information for a plurality of rules in which each rule considers an operating parameter of the heat exchanger that is based on the measurement information to provide a set of operating values; compare the set of operating values to a rules matrix in which each of a plurality of possible diagnoses for the heat exchanger are associated with a corresponding set of predetermined values from a set of the plurality of rules; and (iii) based on the comparison, determine at least one likely diagnosis for the heat exchanger from among the plurality of possible diagnoses.

Abstract: A system may use sensor data from a facility to generate tentative values associated with an event, such as the identification of an item removed from a shelf of the facility. A confidence value associated with each of the tentative values may be less than a confidence threshold. In response, inquiry data seeking confirmation of a tentative value from an associate is generated and sent to one or more associates in the facility. Responses from the associates are collected to determine a selection of one of the tentative values. The selected tentative value is designated as output data for the system. Thereafter, the output data and the original sensor data are designated as training data, which can then be used to train or update machine learning systems. Subsequent use of the updated machine learning systems can yield more accurate results.

Abstract: A system and method for automated laser ablation includes an end effector for performing laser ablation at a location with restricted access. The systems and methods of the present disclosure specifically provide for a miniature laser end effector which may be inserted through a port or bore in order to ablate the surface of an internal component of a complex assembly. In several embodiments of the present subject matter, the end effector is mounted on a machine and coupled to a laser system.

Abstract: The present disclosure relates to a recloser control that provides autosynchronization of a microgrid to an area electric power system (EPS). For example, a recloser control may include an output connector that is communicatively coupled to a recloser at a point of common coupling (PCC) between the area EPS and the microgrid. The recloser control may include a processor that acquires a first set of measurements indicating electrical characteristics of the area EPS and acquires a second set of measurements indicating electrical characteristics of the microgrid. The recloser control may send synchronization signals to one or more distributed energy resource (DER) controllers to synchronize one or more DERs to the area EPS based on the first set of measurements and the second set of measurements.

Abstract: Described are systems and techniques configured to provide a user interface for an unauthenticated user of a materials handling facility. A transient profile indicative of one or more user preferences may be created and associated with the unauthenticated user. As the unauthenticated user interacts with the facility, preferences may be determined and included in the transient profile. Subsequent operation of the facility may take into account the transient profile. As the unauthenticated user moves throughout the facility, the transient profile may “follow” them, providing an ongoing user experience. Should the unauthenticated user later be authenticated, the transient preferences may be incorporated into a persistent profile.

Abstract: Functionality of sensors on a shelf or other inventory location is tested by encouraging an interaction and determining if the output from the sensors on the shelf is consistent with the interaction. An interaction at the shelf can include, for example, a user adding or removing an item from the shelf. To encourage this type of interaction with the shelf or items therein, an announcement may be generated and presented to a user. The announcement may comprise an advertisement with some type of incentive for the user to add or remove an item from the shelf. Upon verifying such an interaction, sensor data before and after the interaction can be compared to generate diagnostic data for the sensor, which can indicate whether the sensor is operational or malfunctioning.

The recloser control may determine frequency (F) and a rate of change of frequency (ROCOF) based on the received measurements. The recloser control may detect islanding of a microgrid in the electric power delivery system based at least in part on F and ROCOF. The recloser control may send a signal to the recloser to trip the recloser based on the islanding of the microgrid.
