Abstract: A device and method for preparing a fully granular cigarette/filter rod, and a prepared fully granular cigarette/filter rod are disclosed. In certain embodiments, negative pressure is used to adhere granular material onto a mesh-type conveyor belt. The granular material is preliminarily formed into fully granular cigarette/filter rod material by means of a pre-forming apparatus; the fully granular cigarette/filter rod material, traveling with the mesh-type conveyor belt, enters into a forming cavity, and undergoes heating and humidifying treatment, and a continuous solid porous substance is formed; the continuous solid porous substance is moved into the cooling/drying cavity, drying and cooling treatment are performed under the action of negative pressure, and a fully granular cigarette/filter rod with strong adhesion, porosity, permeability, and appropriate moisture is obtained.

Abstract: A method including establishing a communication connection of a first Internet of Things device with a trusted device; acquiring a first communication key, the first communication key being provided to the first Internet of Things device and/or a second Internet of Things device via the trusted device; performing, on the basis of the first communication key, encrypted communication with the second Internet of Things device, thereby ensuring that the first Internet of Things device and the second Internet of Things device are capable of acquiring the first communication key, and performing encrypted communication on the basis of the first communication key, thus enhancing the security and reliability of communication between the first Internet of Things device and the second Internet of Things device.

Abstract: Identity authentication method, system, and computing device are disclosed. The method includes: an identity authentication method is provided, which includes: a first device establishing a communication connection with a second device, and obtaining encrypted information through the Internet, where the first device is a device that is allowed to access the Internet, and the second device is a device that is not allowed to access the Internet; the first device encrypting identity information of an account that is logged into the second device by using the encrypted information, and sending the encrypted identity information to the second device; and the first device receiving a verification result that is returned by the second device, wherein the second device verifies the encrypted identity information based on verification information.

Abstract: The present disclosure provides a shift register unit, a gate electrode drive circuit and a display apparatus, which relates to a technical field of display. The shift register unit includes an input reset module, a pull up module, a control module and a pull down module. By inputting a high level into the second signal input end of the input reset module in the touch scan to maintain the level at the pull up control node, the electrical leak effects at the pull up control node may be avoided efficiently. In this way, the defects of insufficient charging rate of the row pixels may be avoided and the dark lines or bad bright lines may be suppressed.
