Abstract: An active control method and device for large deformation of a deep thin-bedded surrounding rock, the active control method includes: drill holes in the surrounding rock of a tunnel against a tunnel face, add the active control device containing a sleeve, a high-strength prestressed anchor bolt, a resin anchoring agent and a grouting device into drill holes, apply a preload to the anchor bolt when the resin anchoring agent has a certain strength, and carry out lag grouting in the surrounding rock through the grouting device after stress adjustment, and the high-strength prestressed anchor bolt and the grouting device are inserted in the sleeve with holes on the side. The active control device or method of the invention can effectively reduce the fracture depth and degree of a thin-bedded soft rock in deep engineering, and effectively inhibit the occurrence of large deformation disasters.

Abstract: A control method and a controller are provided. The method includes: controlling an electronic device to connect to a wireless access point corresponding to a first channel based on a first preset rule; controlling the electronic device to connect to a wireless access point corresponding to the first channel or a wireless access point corresponding to a second channel based on a second preset rule; where the first preset rule is different from the second preset rule, and the frequency of the first channel is higher than the frequency of the second channel.

Abstract: A touch sensitive apparatus, a mobile terminal and a terminal device are described. The touch sensitive apparatus includes a main body of the touch sensitive apparatus and an antenna built inside of the main body.

Abstract: A tool for measuring depths of countersunk holes includes a worktable (1), a measuring member (30), and a display device (50). The worktable includes a measuring plate (10) defining four adjusting screw holes (17) in four comers thereof, and four adjusting rods (28) adjustably attached in the adjusting screw holes below the measuring plate. The adjusting rods are adjusted so that the measuring plate can be level. The measuring member is generally cylindrical, and includes a cylindrical head (32) having a conical tip (34). The display device includes a vertical central shaft (58), and a bearing sleeve (60) surrounding a bottom of the central shaft. The central shaft can move vertically through the bearing sleeve. The display device further includes a cylindrical body (52) having a display (54) showing a height value of a top face of the central shaft, and a zeroing button (56).
