  • Publication number: 20150287387
    Abstract: An electronic device and an operation mode switching method thereof are described. The operation mode switching method is applied to an electronic device that includes a display unit, and the electronic device has a first operation mode and a second operation mode. The display unit has a first light-transmittance in the first operation mode and a second light-transmittance in the second operation mode such that the first high light-transmittance is higher than the second light-transmittance. The method includes detecting to obtain a trigger event; judging whether or not the trigger event satisfies a predefined condition to get a judgment result and, when the judgment result indicates that the trigger event satisfies the predefined condition, generating a switching instruction, and according to the switching instruction, switching the electronic device between the first operation mode and the second operation mode.

  • Publication number: 20140240224
    Abstract: A display method and an electronic device are described. The display method is applied in an electronic device that includes a display unit and at least one sensing unit. The method includes obtaining first sensing data by a first sensing unit; determining first display information according to the first sensing data; judging whether a predetermined condition is met or not to obtain a judgment result; and selecting a first mode or a second mode to be used to determine a display position of the first display information on the display unit according to the judgment result, wherein the first mode is different from the second mode; and displaying the first display information at the display position.

  • Patent number: 8488512
    Abstract: The present invention discloses a resource scheduling method for multi-hop relay wireless network comprising: for each of a base station and relay stations, acquiring the minimal resource requirement of each of connections to all MSSs which are covered by said station and have direct signal transmission with said station, and then summing up the acquired resource requirement to obtain the minimal resource requirement of said station; and acquiring interference status between the relay stations, using different partition strategies to classify the relay stations into different independent sets, each of which can occupy the same resource, according to the minimal resource requirement of the base station and the relay stations as well as the interference status between the relay stations, and determining and comparing the total resource requirement under each of the partition strategies to obtain an optimized partition strategy for resource reuse scheduling.
