Abstract: An automatic uncoupled charging device includes a control system, a power system, a charging system, and an auxiliary system. The control system is equipped with a programmable circuit to control a screw speed. Explosives are charged into a container through manual handling or flowing from a mixed explosive vehicle. Explosive bags with different diameters are installed at the bottom of a discharge port. The device is set to start with one click, and the screw drives the explosive into the bag, achieving uncoupled charging. An automatic uncoupled charging method applying to the automatic uncoupled charging device not only reduces labor intensity, achieves fast charging, improves labor efficiency, but also achieves the goal of “mechanization reducing personnel”, further advancing towards the essential safety of blasting construction.

Abstract: The present disclosure provides a method and a device for inspecting a defect of a liquid crystal panel.

Abstract: Systems, methods, and non-transitory computer readable media can obtain a first event stream including one or more events of a first type, where each event of the first type is associated with a timestamp. A second event stream including one or more events of a second type can be obtained, where each event of the second type is associated with a timestamp. The first event stream and the second event stream can be merged to generate information associated with a metric relating to a system, based on the timestamps associated with the one or more events of the first type and the timestamps associated with the one or more events of the second type.

Abstract: Techniques for estimating user attention on a website or application are provided. First activity data for a first user of a website or an application may be identified. The first activity data may indicate activities of the first user on the website or the application. A first predetermined period of inactivity may be detected in the first activity data. A response triggering event may be initiated after the first predetermined period of inactivity. An indication of a user response to the response triggering event may be monitored for. Whether the first user is passively present on the website or the application may be determined based on the monitoring for the indication of the user response.
