Abstract: A prediction method for selecting a target object for use in an electronic device is provided. The method includes the steps of: (A) displaying a plurality of objects and a cursor on a display of the electronic device; (B) obtaining moving speed, a moving vector, and a cursor position of the cursor as well as a plurality of object positions of the objects; (C) in response to the cursor position and the object positions satisfying a predetermined condition, determining whether a previously selected object exists; (D) in response to the previously selected object existing and the moving speed of the cursor being greater than a speed threshold, selecting the object with the shortest distance to the cursor as the target object by referencing the previously selected object and referring to the motion vector.

Abstract: A verifying method for software authorization under an offline environment is disclosed. The method includes: executing an application software in an electronic device; obtaining a serial number to input to the application software; decrypting the serial number to at least retrieve a requested using term, and a hard-drive identification time information of a hard-drive of the electronic device recorded at the time the serial number being applied; obtaining a power-on time of the hard-drive of the electronic device; computing a using time of the application software in the electronic device according to the hard-drive identification time information and the power-on time; determining whether an authorization to the application software is expired according to the using time and the requested using term; and disabling the application software if the authorization to the application software is expired.

Abstract: An energy management method is provided. The energy management method comprises the steps of retrieving load information from at least one load and retrieving energy-supplying information from an energy supply system having a grid power source, a renewable energy generation module and an energy storage module to instantly calculate first and second energy thresholds. When an energy production of the renewable energy generation module is smaller than the second energy threshold, the grid power source or the energy storage module is controlled to supply energy to the load. When the energy production is between the first and the second energy thresholds, the renewable energy generation module is controlled to supply energy to the load. When the energy production is larger than the first energy threshold, the renewable energy generation module is controlled to supply energy to the load and charge the energy storage module.
