Abstract: This application discloses a method of performing an attack operation in a game by a computing device. The computing device determines a target range corresponding to a first attack operation performed by a first controlled object; determines a target attack object from to-be-attacked objects according to attribute values of the to-be-attacked objects in a case that there are the to-be-attacked objects in the target range, the to-be-attacked objects belonging to a second group, and the attribute value of the to-be-attacked object including: a reduced health value of the to-be-attacked object after the first attack operation is performed on the to-be-attacked object, and/or, a reduced health value of an object in the first group after a second attack operation of the to-be-attacked object is performed on the object; and then controls the first controlled object to perform the first attack operation on the target attack object in the virtual scene.

Abstract: Big data health service method and system based on remote fundus screening are provided. The method includes steps of: acquiring information to be analyzed sent by remote terminal agency; pre-interpreting information to be analyzed, and judging whether information to be analyzed is qualified; extracting characteristic data from information to be analyzed if it is qualified, and forming structured quantitative index; sorting and analyzing characteristic data and quantitative index according to knowledge calculation model to obtain analysis conclusion; and storing information to be analyzed, characteristic data, quantitative index, and analysis conclusion into pre-designed database.

Abstract: An LED based lighting method and a lighting fixture thereof includes multiple LEDs mounted on an LED lamp stand and arranged in array; a convex lens is disposed to a front of each LED; depending on the quantity of LEDs, the area to be illuminated is classified into multiples illuminated units with each corresponding to one LED; convex lenses of different focusing angles of beam of light are selected in case of a fixed focal length or the focal length of each lens device is adjusted so to select or regulate for a proper LED illuminating angle; no dark area exists and the brightness of the area illuminated is very consistent since the spot created by the LED illuminating beam of light after focusing by the convex lens over the area to be illuminated merely covers its corresponding illuminated unit; all the LEDs are mounted on the LED lamp stand properly spaced at intervals and a housing of each LED is totally exposed in the air to skip heat radiation device for lowering production cost, and making the LED stree
