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: In a method for displaying virtual buttons, a plurality of virtual buttons in a virtual scene is displayed. Each virtual button of the plurality of virtual buttons is displayed in one of an inactive form, a selectable form, and an activated form. Each virtual button is configured to trigger a virtual character to perform an interaction operation on an interaction object of the respective virtual button. In response to a determination that an initial condition associated with a virtual button of the plurality of virtual buttons being satisfied, the virtual button is switched from the inactive form to the selectable form. In response to a determination that the virtual button is triggered, the virtual button is switched from the selectable form to the activated form. In response to the virtual button being in the activated form, the virtual character is controlled to perform the interaction operation on the interaction object.

Abstract: This application provides an interaction method in a virtual scene performed by an electronic device. The method includes: displaying a plurality of interaction objects and at least one interaction control in a virtual scene; controlling, in response to a press operation for a first interaction control, the first interaction control to be in a pressed state; controlling, in response to a selection operation for a first interaction object that is triggered based on the first interaction control in the pressed state, the first interaction object to be in a selected state; and performing, in response to a release operation for the press operation, an interaction operation associated with the first interaction control for the first interaction object.

Abstract: An image forming system includes an image forming apparatus and a host terminal connected to the image forming apparatus via a communication line. The image forming apparatus includes a receiving unit, a web page unit, a memory unit, a printing control unit, and a printing unit. The receiving unit receives printing data. The web page unit forms web page information for setting, for each identification information, printing setting information used for printing the printing data. The memory unit stores the printing setting information. The printing control unit controls printing of the printing data based on the printing setting information. The printing unit prints the printing data. The image forming apparatus is capable of printing without installing any printer driver on the side of the host terminal.
