Abstract: A system may automatically conduct hygiene cycles for a confined space such an interior space of a box suitable for storing and/or carrying packaged food. The system may include a hygiene device that can be attached to the box to conduct the hygiene cycles. The system may also automatically collect information related to the hygiene cycles and transmit the collected information to a network.

Abstract: The present disclosure provides a short-process high-performance forming method of a high-strength aluminum alloy, and use thereof. In the present disclosure, pre-hardening treatment is conducted on an obtained W-temper aluminum alloy sheet blank after a solution treatment and quenching, to obtain a pre-hardened aluminum alloy sheet blank for batch supply. The pre-hardened aluminum alloy sheet blank is subjected to plastic forming, to obtain a component with satisfactory performances. After the pre-hardening treatment, a high-strength aluminum alloy sheet blank forms a GPII zone that is completely coherent with a matrix, and has a room-temperature formability exceeding that off traditional soft sheet blank. Moreover, the GPII zones interact with dislocations during the forming, resulting in planar slips. In this way, large-scale dynamic recovery is more effectively suppressed, thus enhancing a work hardening ability of a formed component.

Abstract: Hydrocarbon exploration and extraction can be facilitated using machine-learning models. For example, a system described herein can receive seismic data indicating locations of geological bodies in a target area of a subterranean formation. The system can provide the seismic data as input to a trained machine-learning model for determining whether the target area of the subterranean formation includes one or more types of geological bodies. The system can receive an output from the trained machine-learning model indicating whether or not the target area of the subterranean formation includes the one or more types of geological bodies. The system can then execute one or more processing operations for facilitating hydrocarbon exploration or extraction based on the seismic data and the output from the trained machine-learning model.

Abstract: Embodiments of the present application provide a method and device for identifying a new master battery pack. The method includes a first battery pack detecting that a master battery pack is removed from a battery cabinet of a power cabinet. The method may detect that a new battery pack is not connected to the battery cabinet within a time period after the master battery pack is removed. The time period indicates a longest time that the power cabinet continues to operate in its current configuration after the master battery pack is removed. The method may identify the new master battery pack and new slave battery packs according to the sorted result when the new battery pack is not connected to the battery cabinet within the time period. The new master battery pack may be automatically identified according to its identifier, eliminating manual configuration by a user, and improving configuration efficiency.

Abstract: Embodiments of the present application provide a method and device for identifying a master and slave battery packs. The method includes a first battery pack obtaining, after it is connected to a battery cabinet, its identifier, and obtaining identifiers of other battery packs in the battery cabinet through a communication bus. The total number of the battery packs is N, where N is a positive integer. The method may sort the identifiers of the first battery pack and of the other battery pack to obtain a sorted result. The method may identify the master battery pack and slave battery packs among the first battery pack and the other battery packs according to the sorted result. Each of the battery packs connected to a battery cabinet may automatically identify the master battery pack and slave battery packs according to their identifiers, eliminating manual configuration by a user, and improving configuration efficiency.
