| 20090049327 | COMPUTER SYSTEM WITH ADJUSTABLE DATA TRANSMISSION RATE - A computer system has an adjustable data transmission rate between a CPU and a core logic chip thereof. In the computer system, the CPU has a power state adjustable in response to a power management control signal issued by the core logic chip. For adjusting data transmission rate between the CPU and the core logic chip, a change of an asserted time of the power management control signal from a first time period to a second time period is first determined to obtain an index value. The data transmission rate is increased or decreased according to the index value. | 02-19-2009 |
| 20100275045 | POWER MANAGEMENT METHOD AND RELATED CHIPSET AND COMPUTER SYSTEM - A power management method for use in a computer system having a processor, a power management module and a phase lock loop circuit (PLL) is provided. The power management module is coupled to a plurality of peripheral modules and the computer system and the processor are capable of being operated in a working state and power saving states. The method includes the following. When the computer system is operated in the working state and the processor is entered into a lowest power consumption state among the power saving states, states of the peripheral modules are detected to determine whether a specific condition has been matched. If the specific condition is matched, the processor is directed to a control state to control the PLL according to a control state configuration. | 10-28-2010 |
| 20100281277 | COMPUTER SYSTEM AND STAND-BY MODE MANAGEMENT MODULE AND STAND-BY MODE MANAGEMENT METHOD USING THE SAME - A stand-by mode management module applied in a computer system having a BIOS (basic input/output system), a graphic module and a display module is provided. The computer system is operated in a working state and at least one stand-by state. The module includes a timer and an interrupt generation unit. The timer starts a count period when detecting that the computer system is idle. The interrupt generation unit generates an interrupt request to the BIOS to request the computer system to prepare to enter to a specific state when the count period is reached. When the specific state is entered, the computer system enters the stand-by state, a PLL (phase lock loop) of the display module keeps turning on, and PLLs other than the PLL of the display module are turned off and the graphic module acquires a frame stored in a fixed area of a storing unit and displays the acquired frame on the display module. | 11-04-2010 |

| 20090123142 | METHOD FOR MEASURING SUBJECT DISTANCE - An exemplary method for measuring a distance from a subject to a camera includes the following operations: focusing on the subject using the imaging system; illuminating an area on the subject using auxiliary light; capturing an image of the subject, the image having an illumination portion corresponding to the illuminated area; measuring the area of the illumination portion of the image; and calculating the subject distance based on the measured area. | 05-14-2009 |
| 20100259640 | DIGITAL IMAGE CAPTURE DEVICE AND DIGITAL IMAGE PROCESSING METHOD THEREOF - An image capture device includes an image capture unit, a switching unit, a calculation unit, a comparison unit, and a display unit. The image capture unit captures consecutive images. The switching unit switches to a playback mode. The calculation unit calculates each of gradient values between adjacent pixels within each the image and cumulates a total value composed of the gradient values of the image. The comparison unit compares different total values corresponding to different images to determine the image having a maximum total value. The display unit displays the acquired image. | 10-14-2010 |
| 20100272368 | IMAGE PREVIEWING SYSTEM CAPABLE OF AUTOMATICALLY MAGNIFYING FACE PORTION IN IMAGE AND MAGNIFYING METHOD THEREOF - An image previewing system includes a display unit, a face portion recognition unit, a selecting unit, a comparing unit and a magnifying unit. The display unit comprises a screen configured to show an image. The face portion recognition unit is configured to recognize any human face contained in the image and determine face portions in the image if human face(s) exists in the image. The selecting unit is configured to select one of the face portions in the image. The comparing unit is configured to compare the number of image pixels of the selected face portion with the resolution of the screen of the display unit and generate a result. According to the result, the magnifying unit configured to magnify the selected face portion and display the magnified face portion on the screen. | 10-28-2010 |

| 20090055669 | METHOD, COMPUTER SYSTEM AND CONTROL DEVICE FOR REDUCING POWER CONSUMPTION - A computer system is provided. In one embodiment, the computer system includes a memory, a peripheral device, a central processing unit (CPU), and a peripheral device controller. The CPU stores information about the data transmission in a descriptor in the memory when data transmission between the CPU and the peripheral device is required. The peripheral device controller reads the descriptor from the memory at an access frequency, records whether the descriptor read from the memory requests for data transmission as a recording result, and adjusts the access frequency according to the recording result. | 02-26-2009 |
| 20090256682 | PRODUCT MANAGING SYSTEM AND METHOD USING RFID TECHNOLOGY - A product managing system and method using RFID technology is provided. The product managing system includes an RFID tag, an RFID reader, and a server. The RFID tag is set on a product for providing a tag ID, an object type and attribute, and an event content. The RFID reader reads the RFID tag. The server obtains various information provided by the RFID tag set on the product from the RFID reader, determines the product ID according to the tag ID, determines a class of the product and whether the product is correctly combined with another product according to the object type and attribute, and determines whether a processing procedure of the product is correctly conducted according to the event content. The server finally determines whether the product is normal according to the aforementioned determinations. | 10-15-2009 |
| 20090300376 | CONTROL METHOD AND COMPUTER SYSTEM FOR ADVANCED CONFIGURATION AND POWER INTERFACE - Provided is a control method for an advanced configuration and power interface (ACPI) in a computer system. The computer system comprises a processor and a bus master, wherein the processor, as defined by the ACPI specification, has a first state (C | 12-03-2009 |
