Abstract:
A storage device for refreshing pages of a flash memory comprises a flash memory, an ECC detector and a controller. The flash memory has a plurality of pages, and each page comprises a data area for storing data and a spare area for storing error correction code (ECC) corresponding to the data. The ECC detector is used to get the number of error bits of each page. The controller coupled to the ECC detector is used for storing data and ECC in a first page to a second page when a number of used bytes of the ECC stored in a spare area of the first page exceeds a first predetermined value. A number of used bytes of the ECC stored in a spare area of the second page is less than the first predetermined value. The second page is a blank page.

Abstract:
A dynamic power management system for USB hub and method thereof are described. The dynamic power management system includes a host device, a power unit and a hub device. A power management module disposed in the hub device dynamically adjusts the power-supplying statuses of ports in the hub device and further reduces the cost of power transformer externally connected to the hub device.
Abstract:
An electronic apparatus having switching unit is described. The electronic apparatus includes a first peripheral device, a second peripheral device and a switching unit. The first peripheral device communicates with the host unit. The second peripheral device communicates with the host unit and the first peripheral device, respectively. The switching unit switches to the host unit and the first peripheral device for allowing the host unit to access the first peripheral device via a first path. The switching unit switches to the host unit and the second peripheral device for allowing the host unit to access the second peripheral device via a second path. The switching unit switches to the first peripheral device and the second peripheral device for allowing the first peripheral device to access the second peripheral device via a third path.

Abstract:
A multi-streaming web camera controlling system and controlling methodology are capable of providing an original video data stream and at least one compressed video data stream for displaying demands of local host and for requested video data format(s) by remote hosts, respectively. The host can selectively display the original video data stream and transmit the compressed video data stream(s) through the Internet directly in order to satisfy the video requirements of both the local host and remote hosts. The multi-streaming web camera controlling system and controlling methodology can reduce the consuming system resource of the host for processing a video data stream. Therefore, the multi-streaming web camera controlling system and controlling methodology are capable of decreasing the cost of the host and improving the performance for processing video data stream with improved quality.
Abstract:
A paper-shaped non-volatile storage device includes a top paper layer, a bottom paper layer and a flexible printed circuit board packaged between the top paper layer and the bottom paper layer. The flexible printed circuit board comprises a data-transmitting interface, a non-volatile memory controller and at least one non-volatile memory disposed thereon. Therefore, the paper-shaped non-volatile storage device features as both of traditional paper and traditional non-volatile storage devices, such as instantly writing, manually binding, and outwardly visible content as provided by the traditional paper sheets, and digital information storage, repeatable editing and rapid search capability as provided by the traditional non-volatile storage devices.
Abstract:
The proposed invention discloses a card reader controlling apparatus based on Secure Digital (SD) protocol, which comprises a high-speed bus interface, at least one SD host, at least one SD connection interface and SDIO connection interface (SD/SDIO interface), at least one bridge, and at least one other specific memory card connecting interface. The card reader controlling apparatus according to the proposed invention is capable of directly accessing data from/to an input/output device compatible with the SDIO connection interface (e.g. an SD card) or one other specific memory card via the high-speed bus interface. Thus, multiple format conversions performed by other peripheral bus interfaces (such as an USB interface) as the prior art can be by-passed or eliminated.
