| 20090180415 | METHOD, APPARATUS AND COMPUTER READABLE MEDIUM FOR REDUCING POWER-CONSUMPTION OF WIRELESS NETWORK DEVICE - A method, an apparatus, and a computer-readable medium to reduce power consumption of a wireless network device, the method including: receiving a packet; and determining whether to transmit the received packet to a host based on a state of the host and a packet transmission standard set for the host. Accordingly, it is possible to extend a period of use of a wireless portable terminal using an Internet protocol (IP)-based wireless network. | 07-16-2009 |
| 20090181713 | METHOD AND APPARATUS FOR CONTROLLING POWER SOURCE OF TERMINAL DEVICE FOR COMMUNICATING WITH WIRELESS WIDE AREA NETWORK - A method of controlling a power source of a terminal device for communicating with a wireless wide area network, the method including: receiving a data packet; determines whether only some components of the terminal device are to be used to process the received data packet or whether an entirety of the terminal device is to be used to process the received data packet; and based on the determination result, waking up the some components of the terminal device or the entirety of the terminal device from a sleep mode to an awake mode so as to process the received data packet. | 07-16-2009 |
| 20090275345 | APPARATUS AND METHOD FOR PROVIDING LOCATION INFORMATION AND APPARATUS FOR SUPPORTING LOCATION BASED SERVICE AND METHOD FOR USING LOCATION BASED SERVICE - A location information providing apparatus to provide a location thereof, the location information providing apparatus including: a storage unit to store location information regarding the location of the location information providing apparatus; and a transmitter to transmit the location information. Therefore, precise location information can be provided. In addition, a location-based service can be performed in a simple way because there is no need to consider a handoff depending on a movement of a location-based service supporting apparatus, and a service area can be expanded abroad because a wired network is not required. Also, various opportunities using the location-based service can be realized. | 11-05-2009 |

| 20080288698 | CARD READER CONTROLLING APPARATUS BASED ON SECURE DIGITAL PROTOCOL - 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. | 11-20-2008 |
| 20090132757 | STORAGE SYSTEM FOR IMPROVING EFFICIENCY IN ACCESSING FLASH MEMORY AND METHOD FOR THE SAME - A storage system for improving efficiency in accessing flash memory and method for the same are disclosed. The present invention provides a cache unit for temporarily storing data prior to writing in the flash memory or reading from the flash memory. In reading process, after data stored in a flash memory is accessed by a host, the cache unit holds the data. Upon subsequent read requests to read the same data, the data is cached accordingly, thereby shortening a preparation time for reading the data from the flash memory. In writing process, a host requests write a series of requests to write data into the flash memory, the data is gathered and is stored in the cache unit until the cache unit is full. A cluster of data in the cache unit is accordingly written into the flash memory, so that a preparation time for writing the data into the flash memory is also shortened. | 05-21-2009 |
| 20100180050 | COMMUNICATION SYSTEM CAPATIBLE TO UNIVERSAL SERIAL BUS (USB) AND METHOD THEREOF - A communication system compatible to universal serial bus (USB) and method thereof are described. The communication system includes a client electronic device and a remote electronic device. The client electronic device establishes a communication link to the peripheral device connected to the remote electronic device. The client electronic device has a virtual host controller unit and a client application program module. The virtual host controller unit receives the control command and stores the control command. The client application program module sends the control command. The remote electronic device has a remote application program module and a physical host controller unit. The remote application program module analyzes the control command from the client application program module. The physical host controller unit performs the analyzed control command. The peripheral device based on the universal serial bus (USB) generates response data corresponding to the analyzed control command and the peripheral device based on the universal serial bus (USB) transmits the response data back to the device driver of the client electronic device. | 07-15-2010 |
| 20110016261 | PARALLEL PROCESSING ARCHITECTURE OF FLASH MEMORY AND METHOD THEREOF - A parallel processing architecture of flash memory and method thereof are described. A processing unit classifies a plurality of commands to generate a first command group and a second command group respectively. The processing unit executes the first command group and the second command group. A first control unit performs the first command group to access the data stored in the first memory unit, and a second control unit simultaneously performs the second command group to access the data stored in the second memory unit for processing the data stored in the first and the second memory units in parallel. | 01-20-2011 |
