Publication number: 20120098844Abstract: A refresh rate adjustment method automatically adjusts a refresh rate of a monitor connected to a computer to a default refresh rate, in response that a detected keystroke signal is a predefined keystroke signal. The method further detects a refresh rate range that is supported by the monitor, detects a new refresh rate input signal from the input device, and determines if the new refresh rate falls within the refresh rate range that is supported by the monitor. If the new refresh rate falls within the refresh rate range that is supported by the monitor, the method automatically adjusts the refresh rate of the monitor with the new refresh rate. Otherwise, the method prompts a user to input the new refresh rate again by displaying a dialog box on the monitor.Type: ApplicationFiled: June 29, 2011Publication date: April 26, 2012Applicants: HON HAI PRECISION INDUSTRY CO., LTD., HONG FU JIN PRECISION INDUSTRY (ShenZhen) CO., LTD.Inventors: MING-JING SONG, YAN LI, DE-HUA DANG

Publication number: 20120049651Abstract: A power switch control device includes a control chip connected to power switches distributed in a room, and a microcontroller connected to the control chip. When a person gets through an entry/exit door of the room, both of a first sensor fixed to an interior surface of the door and a second sensor fixed to an exterior surface of the door sense the person. By comparing record times of the two sensors, the microcontroller can determine whether the person enters or exits the room. If the person enters the room and a count value is changed to one from zero, the microcontroller sends a power-on command to the control chip to switch the power switches on. If the person exits the room and the count value is changed to zero from one, the microcontroller sends a power-off command to the control chip to switch the power switches off.Type: ApplicationFiled: December 24, 2010Publication date: March 1, 2012Applicants: HON HAI PRECISION INDUSTRY CO., LTD., HONG FU JIN PRECISION INDUSTRY (ShenZhen) CO., LTD.Inventors: XIANG YU, DE-HUA DANG, GE-XIN ZENG
