Abstract: This application relates to an image acquisition method performed by a computer device. The method includes: displaying a mapping pattern corresponding to a key area of a target part of a target object in response to a pattern display operation triggered by the target object; changing a display state of the currently displayed mapping pattern when a relative position of the target part relative to an image acquisition element changes; and acquiring a key area image of the target part contactlessly by using the image acquisition element when the currently displayed mapping pattern matches a preset recognition pattern.

Abstract: Implementations of the disclosed technologies pre-fetch search results. Implementations receive first input from a search session of a user device, where the first input includes at least a portion of a search term but does not initiate a search. Implementations determine context data associated with the first input, determine that a combination of the first input and the context data satisfies a pre-fetch threshold, determine intent data based on at least a portion of the context data, generate a search query based on the first input and the intent data, and pre-fetch a first subset of search results based on the search query. In response to a second input received subsequent to the first input, where the second input contains an initiate search signal, implementations initiate rendering of the pre-fetched first subset of search results in the search session at the user device.

Abstract: An effective capacity estimation method and system for super capacitor energy storage systems are provided. The method includes: establishing a nonlinear electrical model of supercapacitor cell and an equivalent electrical model of a supercapacitor system; obtaining the first test data by charging the supercapacitor cell; based on the first test data, setting the initial value of parameters of the nonlinear electrical model of the supercapacitor cell by a preset algorithm; using a least-square method to identify the parameters of the nonlinear electrical model of the supercapacitor cell; obtaining electrical parameters of the equivalent electrical model of the supercapacitor system except the connection resistance parameters, carrying out a charging test of the supercapacitor system to obtain the connection resistance parameters, and estimating an effective capacity of the supercapacitor energy storage system based on the equivalent electrical model of the supercapacitor system after parameter identification.

Abstract: Provided is a fermentation fungal substance of Astragalus membranaceus/Paecilomyces cicadae and its use. The fermentation fungal substance is obtained by solid fermentation with Astragalus membranaceus powder as a fermentation substrate and Paecilomyces cicadae as a fermentation strain. The fermentation fungal substance of Astragalus membranaceus/Paecilomyces cicadae in the present disclosure plays a significant role in treating hyperuricemia and/or hypertriglyceridemia.

Abstract: A multi-user uplink and downlink beam alignment method for asymmetric millimeter wave large-scale MIMO includes constructing an all-digital multi-directional beam for multiple-direction probing; performing multiple rounds of downlink beam training from the base station to the UE; controlling the UE to perform a beam decision according to the receiving signals, and determining a target downlink sending-receiving beam pair; performing data processing on the receiving signals to generate training data for predicting an uplink sending narrow beam, and performing training on a preset neural network; performing online real-time signal detection based on the trained network parameters and the receiving signals to predict a target uplink sending narrow beam; and controlling the UE to feedback an index of a target downlink sending narrow beam to the base station, and widening the target downlink sending narrow beam into a target uplink receiving beam according to the feedback index.

Abstract: A safety gate for selectively covering socket holes of an electrical outlet comprises an upper slide plate comprising an upper space with an upper recessed platform on a first side and an upper slant on an opposed side. A lower slide plate comprises a lower space with a lower slant on a first side and a lower recessed platform on an opposed side. The upper and lower spaces allow load plug pins to pass through, and the intervals of the spaces correspond to the interval of load plug pins. The upper slide plate is stacked with the lower slide plate to overlap the upper recessed platform with the lower slant and the upper slant with the lower recessed platform. The upper slide plate slides relative to the lower slide plate. Load plug pins slide along the inclined slopes of the upper and lower slants to slidingly displace the upper and lower slide plates a distance that is no less than the thickness of a pin.
