Abstract: The present disclosure provides a terminal and a method for managing launch of an application of the terminal. The method includes: receiving a first indication from a user, wherein the first indication indicates that the launch of the application needs to be banned; in response to the first indication, setting the application to a launch-restricted state, wherein the launch-restricted state means that the application is prohibited from being launched by itself or by other applications; receiving a second indication from a user, wherein the second indication indicates that the launch-restricted state needs to be removed; and in response to the second indication, setting the application to a launch-allowable state, wherein the launch-allowable state means that the application is allowed to be launched by itself or by other applications.

Abstract: An adjustable tray system is provided. The adjustable tray system may include a working table and a support member, where the support member may attach the working table with a supporting structure. The adjustable tray system may also include at least one adjustment mechanism. The adjustment mechanism may couple the working table with the support member such that an angle is formed between the support member and the working table. The adjustment mechanism may also allow angular adjustment of the working table such that the working table pivots about a rotation point of the adjustment mechanism. The adjustable tray system may be used in conjunction with a height adjustment platform, such as for an adjustable keyboard tray of a height adjustable desk.

Abstract: A height adjustment mechanism is provided. The height adjustment mechanism includes a lifting arm, a driving mechanism configured to drive and lock the lifting arm, and a control switch configured to control the driving mechanism; the driving mechanism is coupled to the lifting arm, and an angle is formed between the driving mechanism and the lifting arm. A height adjustment platform and method is also provided. The height adjustment platform includes a first working table, a bottom bracket, a lifting arm, a driving mechanism configured to drive and lock the lifting arm, and a control switch configured to control the driving mechanism; two opposite ends of the lifting arms are separately coupled to the first working table and the bottom bracket, the driving mechanism is coupled to the lifting arm, and the angle is formed between the driving mechanism and the lifting arm.

Abstract: This invention provides a modular locker shelf with firm structure. It is easy to be assembled and disassembled. This locker shelf includes two side frames, a top shelf board and a bottom shelf board between two side frames; it also includes at least one middle side frame between top shelf board and bottom shelf board and one or more middle shelf board, which can be disassembled and connected with the side frame and middle side frame. The top shelf board and bottom shelf board can be disassembled and connected with two side frames. The space of the locker shelf can be flexibly changed according to needs, and can be placed in the locker to improve the organizing function of the storage. This shelf is easy for assembling and dissembling and it is also convenient for transport. As a result, it is beneficial to expanding the use of shelf.

Abstract: This invention provides a shelf with simple structures. It can be easily assembled and disassembled. The shelf includes a stand column, a main frame, a side frame and a metal bracket. The main frame and the side frame are connected to the stand column by metal bracket to make a shelf with two tiers or more. The stand column is connected to the metal bracket along with a setup of convex circle for the fixation. The shelf of this invention is firm and steady, easy to assemble and disassemble with high loading capacity. The shelf serves as a storage device with simple structure; moreover it is convenient for the transport, thus can be widely used in office supplies.
