Abstract: A double-sided composite spectacle lens and an inject mold therefor are provided. One surface of the spectacle lens is an aspherical surface, and the other surface is a designed aspherical surface used to inhibit astigmatism, and a spectacle lens formed by combining the two surfaces has two areas with different functions: optimizing optical performance, and thinning for aesthetics. By controlling the reduction of diopter and optimizing astigmatism on one surface, and inversely offsetting astigmatism on the other surface, the degree of astigmatism of the spectacle lens formed by combining the two surfaces is significantly lower than a diopter variation, and the degree of oblique astigmatism is significantly reduced. The aesthetic thinning effects of reducing the edge or center thickness of the double-sided composite spectacle lens are significantly enhanced by accelerating reduction of the diopter on one surface and changing from reducing to increasing the diopter on the other surface.

Abstract: A computer startup method, a startup apparatus, a state transition method, and a state transition apparatus are described. When the computer is in a suspend-to-RAM (STR) state, the power consumption is a first power consumption. When the computer transitions from the suspend-to-disk (STD) state to the startup state, the time consumption is a first time consumption. The state transition method includes, when the computer is in the startup state, obtaining a first power state transition command to instruct the computer to transition from the startup state to a specific state; and to respond to the first power state transition command, making the computer to be in the specific state.

Abstract: Methods and electronic devices for adjusting an operating frequency of a memory are disclosed. The method includes: transmitting to the memory a first command that instructs the memory to hold the data information in the memory; transmitting to the memory controller a second command that adjusts the first frequency of the memory controller to a second frequency; and transmitting to the memory a third command that instructs the memory to exchange the data information according to the second frequency of the memory controller. According to the disclosure, it is possible to dynamically adjust the frequency of the memory during operation, avoiding the need of the user to turn off and then turn on the electronic device to adjust the frequency of the memory.

Abstract: An information processing method, system and an electronic device are provided according to the embodiments of the disclosure, and applied to an electronic device having at least a first panel, with a first surface of the first panel being provided with a display unit and at least one image acquisition apparatus, where the at least one image acquisition apparatus is positioned below the display unit in the case that the first panel stands on a plane. After an image for a to-be-recognized object and the plane is acquired by the image acquisition apparatus, whether the object contacts the plane is determined based on the acquired image, and information about position change on the object is detected in the case that it is determined that the object contacts the plane.
