Patent number: 9412320Abstract: A method and apparatus for adjusting display backlight and an associated computer program product are provided. The method is applied to an electronic device. The method includes the steps of: utilizing at least one light sensor of the electronic device to detect ambient light; and performing a plurality of detection operations to selectively control the electronic device to enter a specific mode to adjust brightness level of a backlight module of a display panel of the electronic device. The detection operations includes: detecting whether the ambient light is less than a predetermined ambient brightness threshold value for a time period; and detecting whether a length of the time period reaches a predetermined time threshold value. For example, the specific mode can be a low-light mode, which is suitable for a user who has stayed in the dark for a time period (e.g. tens of minutes, or one or more hours).Type: GrantFiled: August 23, 2013Date of Patent: August 9, 2016Assignee: HTC CorporationInventors: Po-Ting Chen, Cheng-Hao Chin

Patent number: 8756615Abstract: A method and an electronic device for synchronizing information of dual operating systems and a recording medium are provided. The method is used for synchronizing information of a first operating system and a second operating system when an electronic device is switching from a first operating system to a second operating system. First, the second operating system sends an information requesting message to a controller of the electronic device when the first operating system is switched to the second operating system. The controller checks if the first operating system operates in a work mode. If the first operating system operates in the work mode, the controller forwards the information requesting message to the first operating system, so as to obtain the information of the first operating system. Finally, the second system synchronizes the information recorded therein according to the obtained information.Type: GrantFiled: April 5, 2012Date of Patent: June 17, 2014Assignee: HTC CorporationInventors: Cheng-Hao Chin, Chien-Liang Lin, Shin-Yun Lin

Patent number: 8682277Abstract: A controlling method and a controlling system for a handheld communication device are provided. In the present method, a tilting state of the handheld communication device is detected by using a G-sensor when a notice is activated. Then, whether the tilting state is changed from a face up state to a face down state is determined. The handheld communication device is controlled to perform a function when the tilting state is confirmed to be changed from the face up state to the face down state. Accordingly, the handheld communication device may be controlled to perform a function timely according to the positioned state of the device without going through complicated procedures, so as to provide a more intuitive and convenient way to control the handheld communication device.Type: GrantFiled: July 3, 2012Date of Patent: March 25, 2014Assignee: HTC CorporationInventors: Hok-Sum Horace Luke, Chih-Hua Wang, Ying-Huang Wu, Yi-Lin Chen, Hsiang-Yuan Peng, Yuan-Mao Tsui, Cheng-Hao Chin
