Therefore, the waiting time spent on selecting operation system in the prior art is eliminated. | 11-27-2008 |
| 20080294295 | PREHEATING CONTROL SYSTEM OF INFORMATION PROCESSING DEVICE AND CONTROL METHOD THEREOF - A preheating control system of an information processing device and a control method thereof are described. The system includes a temperature sensing module, a first controller, a heating module, and a second controller. After receiving a power ON signal, the first controller shifts to a primary control mode and determines whether temperature of the hard disk satisfies an operating temperature scope or not. When the temperature does not satisfy the operating temperature scope, the heating module is used to heat the hard disk. When the temperature satisfies the operating temperature scope, the first controller shifts to a secondary control mode and activates the second controller to execute a boot program of the information processing device, thereby improving system stability. | 11-27-2008 |
| 20080291641 | LOCKABLE DOOR ASSEMBLY OF AN ELECTRONIC DEVICE - A lockable door assembly of an electronic device is used to cover and seal an opening of a housing of the electronic device. The lockable door assembly includes a door, a first sliding member, and a second sliding member. The door is pivoted to the housing to cover the opening. The first sliding member is movably disposed on the door for being engaged with a rib formed on the housing, so as to stop the door from rotating. The second sliding member is movably disposed on the door, and the sliding paths of the second sliding member and the first sliding member are intersected. The second sliding member is used for being inserted into a nick of the first sliding member to prevent the first sliding member from moving, thereby a double secure mechanism is achieved and the thickness of the lockable door is reduced. | 11-27-2008 |
| 20080291139 | METHOD OF DYNAMICALLY ADJUSTING SCREEN BRIGHTNESS - A method of dynamically adjusting screen brightness is adapted for a screen to adjust the screen brightness. First, an original ambient light level and an original brightness adjustment factor are determined. Then, a relationship curve of an ambient light level and a brightness adjustment factor is determined. The current ambient light level is continuously monitored and compared with the original ambient light level to determine if the current ambient light level is equal to the original ambient light level. If not equal, a brightness adjustment factor corresponding to the current ambient light level is obtained based on the relationship curve, and the screen brightness is adjusted based on the brightness adjustment factor. The obtained screen brightness and the corresponding brightness adjustment factor are set to be the original screen brightness and the original brightness adjustment factor, and thus the background brightness is monitored again and the screen brightness is adjusted. | 11-27-2008 |
| 20080290258 | AUXILIARY INPUT METHOD FOR ELECTRONIC DEVICE - An auxiliary input method for an electronic device displays a virtual keyboard input interface optionally on a screen of the electronic device according to an external ambient brightness state of the electronic device, so as to assist the users to input data. The method includes sensing current ambient brightness to obtain an ambient brightness value; comparing the ambient brightness value with a preset brightness value; if the ambient brightness value is lower than the preset brightness value, calculating a duration in which the ambient brightness value is lower than the preset brightness value; comparing the duration with the preset time; if the duration reaches the preset time, displaying the virtual keyboard input interface on the screen of the electronic device, thereby improving the operation convenience of the electronic device. | 11-27-2008 |
| 20080198087 | DUAL-BAND ANTENNA - A dual-band antenna is provided, which includes a signal resonance unit, a grounding unit, a connection unit, and a signal line. The grounding unit is disposed opposite to the signal resonance unit. The connection unit has a first connection element and a second connection element, wherein one end of the first connection element is connected to the signal resonance unit and the other end of the first connection element is connected to the grounding unit, while one end of the second connection element is connected to one side of the first connection element. The signal line has a signal feeding end and a circuit connection end, wherein the signal feeding end is electrically connected to the second connection element, and the circuit connection end is electrically connected to a wireless circuit device. | 08-21-2008 |
