  • Publication number: 20240061740
    Abstract: A computer-implemented method for locating root causes is provided. The method includes detecting a trigger point from entity metrics data and key performance indicator (KPI) data, generating a learned causal graph by fusing a state-invariant causal graph with a state-dependent causal graph, and locating the root causes by employing a random walk-based technique to estimate a probability score for each of the entity metrics data by starting from a KPI node.

  • Publication number: 20240061739
    Abstract: A computer-implemented method for identifying root cause failure and fault events is provided. The method includes detecting a trigger point, converting, via an encoder, previous system state data, new batch data in a next system state, and a causal graph to system state-invariant embeddings and system state-dependent embeddings, generating a learned causal graph, via a graph generation layer, by integrating state-invariant and state-dependent information, and predicting, by a prediction layer, future time-series data on the learned causal graph.

  • Publication number: 20190179847
    Abstract: Provided are a slide show control method and an apparatus. The method includes: displaying (S102) a control interface in a slide show interface, receiving (S104) a switch instruction acting on a thumbnail, and in response to the switch instruction, obtaining (S106) the slide page corresponding to the thumbnail on which the switch instruction acts and switching the slide page currently displayed in the slide show interface to the slide page corresponding to the thumbnail on which the switch instruction acts. With the control interface displayed in the slide show interface, after the user inputs the switch instruction on the thumbnail in the control interface, the slide page currently displayed in the slide show interface can be automatically switched to the slide page corresponding to the thumbnail on which the switch instruction acts. And even when a touch device is used to present the slides, the page switch can be done in the show state, which simplifies the user's operation.

  • Patent number: 10082689
    Abstract: A liquid crystal display includes a glass substrate and a driver chip. The liquid crystal display further includes a testing line formed in the glass substrate and extending close to an edge of the glass substrate. The driver chip includes an input pin and an output pin, and two ends of the testing line are separately connected to the input pin and the output pin to form a closed loop. Whether the glass substrate has a crack is determined by measuring whether the testing line is in a closed circuit. The present invention further provides an electronic apparatus and a liquid crystal display testing method. In the present invention, whether a glass substrate has a crack is determined by detecting whether a testing line is in a closed circuit, so as to implement automatic detection without disassembling, thereby increasing detection efficiency.

  • Patent number: 9050817
    Abstract: A storage device includes an interface unit, a storage unit, a detection unit and a control unit. When the detection unit detects a preset trigger condition and the total surplus of the recording material is greater than the capacity of the recording material, the control unit effects the updating of the total surplus of the recording material stored in the storage unit and the erasing of the surplus of the erasable recording material or the consumption amount of the erasable recording material as a calculation value. When the total surplus of the recording material is less than or equal to the capacity of the recording material, the control unit will not actively update the total surplus of the recording material or the consumption amount of the recording material in the storage unit. Provided is a consumption container, which can better manage the data in the storage device.
