  • Patent number: 9888441
    Abstract: A method for managing power usage is perform at a mobile terminal having one or more processors and memory storing programs executed by the one or more processors. The mobile terminal collects its operating environment information while the mobile terminal is in a first operating mode. The mobile terminal compares the collected operating environment information with a plurality of power usage switch conditions, each power usage switch condition having an associated operating mode, to determine whether the collected operating environment information matches one of the plurality of power usage switch conditions. When this happens, the mobile terminal determines its current working status and switches from the first operating mode to the second operating mode when there is no conflict between the mobile terminal's current working status and the second operating mode associated with the matched power usage switch condition.

  • Patent number: 9882816
    Abstract: The present disclosure provides a communication method that a base station configures different CSI-RS ports with different periodicity based on UE requirement (e.g. mobility) to reduce CSI-RS overhead. And another method is to transmit partial CSI-RS ports in a cyclic shifted manner to further reduce the overhead. In addition, cyclic shifted transmission of split CSI-RS port groups are proposed to reduce the potential big difference of interference onto different CSI-RS port groups.

  • Publication number: 20170219859
    Abstract: A display may have a backlight unit that provides backlight illumination. The backlight unit may include a light guide that distributes light throughout the display and an electrically adjustable lens array. The lens array may have lenses such as liquid lenses or liquid crystal lenses. By adjusting the lenses in the lens array, the angles of rays of backlight from the backlight unit may be adjusted to adjust the angle-of-view of the display. The angle-of-view of the display may also be adjusted using an electrically controllable filter layer. The electrically controllable filter layer may have a liquid crystal layer or a polymer dispersed liquid crystal layer that can be controlled using electrodes. When the electrodes apply signals to the electrically controllable filter layer, portions of the filter layer change to a dark or translucent state and restrict the angle-of-view of the display.
