| 20090174258 | Built-in uninterruptible power supply system and electronic device using the same - A built-in uninterruptible power supply system and an electronic device using the same are provided. The built-in uninterruptible power supply system supplies power to an electronic component of an electronic device. The built-in uninterruptible power supply system includes a power supply, a power storage, a power supply switch and a power display. The power supply switch electrically couples the power supply with the power storage. The power supply switch switches to transmit a first power or a second power to the electronic component. The power display is disposed in the casing and electrically coupled with the power storage for displaying a storage power of the power storage. When the external power source stops supplying power to the power supply, the power supply switch switches to transmit the second power from the power storage to the electronic component. | 07-09-2009 |
| 20090199221 | EJECTING MECHANISM CAPABLE OF PREVENTING ACCIDENTAL TOUCH AND DISK DRIVE USING THE SAME - An ejecting mechanism capable of preventing an accidental touch is disposed in a housing having a tray and used for ejecting the tray out of the housing. The ejecting mechanism includes a tray ejecting button and a front cover. The front cover is disposed at the housing and located at the ejecting direction of the tray. The front cover has a sliding key including a pressing body and a triggering body connected to one end of the pressing body. When the pressing body drives the triggering body to slide until the triggering body aligns to the tray ejecting button, the pressing body is capable of being forced to drive one end of the triggering body to trigger the tray ejecting button to eject the tray. | 08-06-2009 |
| 20100102979 | LAPTOP COMPUTER WITH HARDWARE SECURITY PROTECTION - A laptop computer with hardware security protection includes a lid near the image capture module. The lid can move to shield the image capture module to avoid the image captured by the image capture module transmitting to another computer. Therefore, the hardware security protection is achieved by the real lid to prevent the hacker attacking and increase the security protection. | 04-29-2010 |
| 20100134329 | Keyboard Module for Avoiding Accidental Operation - A keyboard module for avoiding accidental operation keyboard module includes a key unit. The key unit has a pressing portion and a contacting portion. The pressing portion abutted the casing for the key unit not being pressed down. The pressing portion can be raised up to form a pressing distance relative to the casing via a push element controlled by a controlling switch to provide the pressing function. Therefore, the keyboard module can effectively prevent the users accidentally striking unnecessary keys during their operations or when the computer is in a power saving mode. | 06-03-2010 |
| 20100236005 | DUMMY CARD CLEANING DEVICE - The invention provides a dummy card cleaning device. The dummy card cleaning device is stored in a card slot of an electronic device to be brought along with the electronic device, so as to provide an immediate and convenient use when cleaning the electronic device. The dummy card cleaning device includes a body having a shape of dummy card, and a brush or a bristle connected to the body. The brush may be stored in an indentation of the body, or slidably, pivotally connected to the body. | 09-23-2010 |
| 20100246874 | FOLDABLE ELECTRONIC DEVICE - A foldable electronic device includes a first body, a second body, a pivot element and a loudspeaker. The pivot element is pivotally connected between the first body and the second body, and the loudspeaker is disposed in the pivot element and is capable of protruding out of a side of the pivot element. | 09-30-2010 |

| 20090100234 | Data Access System and Data Access Method - A data access system and a data access method achieving effects of power saving and access synchronization during data access are provided. The data access system includes a data processing unit, a bridge device and a memory device. The data processing unit sends an access request signal to initiate data access of at least one unit data. The access of unit data is completed within a plurality of clock cycles of a reference clock signal. The bridge device generates an access signal according to the access request signal, the reference clock signal and a leading time. A pulse of the access signal is determined by the leading time within the clock cycles. The memory device executes the access of the unit data according to the access signal. | 04-16-2009 |
| 20090100245 | Device and method for memory addressing - An addressing device and method is provided to enable an electronic system having a less addressing capability to address a memory device having a larger storage space, thereby reducing the manufacture cost of the electronic system. The addressing device includes an address decoder and an address translator. The address decoder receives a first access address belonging to a smaller address space, and determines whether to map the first access address to the larger storage space of the memory device. The address translator is coupled to the address decoder. When the first access address is mapped to the storage space of the memory device, the address translator translates the first access address into a second access address of the larger storage space according to an adjustable base address. | 04-16-2009 |
