Abstract: In example implementations, an apparatus is provided. The apparatus includes a plurality of ports, a magnetic field sensor, a magnetic port cover, and a processor. A subset of ports of the plurality of ports are deactivated and covered with the magnetic port cover. The magnetic field sensor is coupled to each one of the plurality of ports. The processor is communicatively coupled to the magnetic field sensor. The processor is to detect removal of the magnetic port cover from a deactivated port of the subset of ports that are deactivated via a signal from the magnetic field sensor of the deactivated port and generate notification in response to the magnetic port cover being removed to notify a user to replace the magnetic port cover on the deactivated port.

Abstract: An encoding method is provided. The encoding method comprises: encoding a first portion of target data to generate a first two dimensional code; encoding a second portion of the target data by the encoding unit generate a second two dimensional code; generating a three dimensional model according to the first two dimensional code, wherein the three dimensional model includes a plurality of three dimensional modules, the three dimensional modules are arranged along a first direction and a second direction, and a height in a third direction of the three dimensional modules is determined according to the first codes; coloring the three dimensional modules according to the second two dimensional code, respectively, to generate a colored three dimensional model, wherein a color of the three dimensional modules of the colored three dimensional model is determined according to the second codes.

Abstract: A method for adjusting the working frequency of a chip is provided. The method detects a frequency adjustment range of a graphic chip when a system is booted. Then, an application program in full screen mode is executed, and a control hot key is enabled. Afterwards, an input of the control hot key is received to display a user interface. Finally, an input frequency inputted from the user interface is received, and the working frequency of the graphic chip is adjusted according to the input frequency in the frequency adjustment range. Therefore, even though the application program is executed in full screen mode, the working frequency of the graphic chip can still be adjusted according to requirements in any time, which is convenient for the user.

Abstract: A management method of shader clock includes providing a management interface under an operation system environment for receiving an input of a user. When a frequency value to be set of a shader clock input by the user is received, the management method of the present invention can obtain a plurality of parameter values according to the input of the user and respectively write the parameter values into corresponding shader clock registers so as to dynamically set the frequency of the shader clock.
