| 20090121867 | INDOOR LOCATION SYSTEM HAVING SENSOR AND METHOD FOR CHECKING LOCATION USING THE SAME - An indoor location system having a sensor and a method for checking an indoor location using the indoor location system are disclosed. The method includes: calculating a current location coordinate by using nodes; calculating a first movement distance by comparing the current location coordinate and a stored previous location coordinate; calculating a second movement distance through a sensor; and storing the current location coordinate instead of the previous location coordinate when the distance between the first movement distance and the second movement distance is smaller than a predetermined threshold value. Accordingly, an accurate location of an object can be recognized indoors and an error can be prevented from being caused when the location of the object is recognized. | 05-14-2009 |
| 20090150962 | SYSTEM AND METHOD FOR DATA TRANSMISSION IN DLNA NETWORK ENVIRONMENT - A system and method for data transmission in a DLNA network environment are disclosed. The data transmission system includes a content creation unit creating at least one content, a content correlation check unit checking a created content to classify the created content by category and a conversion content creation unit extracting header information and body information of the classified content and converting the extracted information into preset type information. | 06-11-2009 |
| 20090174549 | APPARATUS AND METHOD FOR TRACKING INDOOR TARGET USING WIRELESS DISTANCE MEASURING TECHNOLOGY - A method and system for sensorless tracking of an indoor target using a wireless distance measuring technology. A location tracking apparatus is initially moved, and then it is determined whether or not an initial traveling direction of the location tracking apparatus is forward or backward with respect to the target. A minimum distance between the location tracking apparatus and the target during the movement is determined, the minimum distance is stored, and the location tracking apparatus is moved to a location corresponding to the minimum distance, where it is determined whether the location tracking apparatus is directed forward or backward with respect to the target at the location corresponding to the minimum distance. The location tracking apparatus is then moved to the target. | 07-09-2009 |
| 20090177971 | METHOD AND APPARATUS FOR CONTROLLING DLNA DEVICE IN DLNA NETWORK - Disclosed is a method for controlling a Digital Living Network Alliance (DLNA) device in a DLNA network, the method including the steps of: discovering the DLNA device performing communication with a Universal Plug and Play (UPnP) protocol based format in the DLNA network; converting description provided from the discovered DLNA device into a web-message in order to create a DLNA device list within a corresponding network where the discovered DLNA device is positioned as a web-page; creating the DLNA device list as the web-page, based on the converted web-message, and displaying the DLNA device list; selecting a certain DLNA device from the displayed DLNA device list, and executing/controlling content of the selected DLNA device. | 07-09-2009 |
| 20090204362 | INDOOR LOCATION DETERMINATION SYSTEM AND METHOD - Disclosed are a system and a method for an indoor location determination using a matrix pencil. The system comprises a transmitter node that creates and transmits a transmission packet having a plurality of same symbols. A receiver node receives the transmission packet, calculates a delay time by using the symbols in the transmission packet and a matrix pencil algorithm, and calculates a distance between the transmitter node and the receiver node by using the delay time. The delay time estimation using the matrix pencil can reduce an error ratio and therefore can estimate more exactly the distance between the nodes. | 08-13-2009 |
| 20090207070 | METHOD AND APPARATUS FOR MEASURING DISTANCE IN A WIRELESS ENVIRONMENT - A method and apparatus for measuring a distance in a wireless environment are provided, in which a first device transmits a distance measurement signal to a second device and receives at least one response signal for the distance measurement signal from the second device, matches the received response signal with a reference signal to detect an earliest response signal, and calculates a time taken from the transmission of the distance measurement signal to the second device and the reception of the response signal from the second device using a peak value of the matched reference signal. | 08-20-2009 |
| 20090209268 | LOCATION SENSING SYSTEM AND METHOD FOR MOBILE COMMUNICATION SYSTEM - A location sensing system and method for a mobile communication system is provided for maintaining location sensing service with the support of mobile nodes when there is an insufficient number of anchor nodes for reference points. A location sensing method for a mobile communication system includes discovering, at a source mobile node, anchor nodes in a vicinity; discovering, when a number of discovered anchor nodes is less than a predetermined number of reference nodes required for location sensing, neighboring mobile nodes; selecting at least one of neighboring mobile nodes as a reference mobile node; and computing a location of the source mobile node in cooperation with the predetermined number of reference nodes including the discovered anchor nodes and the reference mobile node. | 08-20-2009 |
| 20090222422 | METHOD, APPARATUS, AND SYSTEM FOR DATA TRANSMISSION BASED ON DLNA NETWORK - The present invention relates to a method, apparatus, and system for data transmission based on a DLNA (Digital Living Network Alliance) network that classifies contents files which are stored in a DMS according to a support of the DLNA network to make a contents list. Support is provided to convert a file attribute of a selected file into a file attribute which can be applied to the DLNA network to generate, in case a user selects a non-supported file which is not applied to the DLNA network. The invention outputs the selected file to a display unit, captures the outputted image to convert into a file which can be applied to the DLNA network. | 09-03-2009 |
| 20100228758 | DIGITAL LIVING NETWORK ALLIANCE SYSTEM AND METHOD FOR PROVIDING CONTENT THEREIN - A Digital Living Network Alliance (DLNA) system and method of providing content therein are provided. A legacy media player displays a content list for content stored in the legacy media player or in an add-in server, and when a content item is selected from the list, the legacy media player determines whether the content item is reproducible by a registered digital media renderer. If the selected content item is reproducible by the registered digital media renderer, the legacy media player transmits a reproducing request for the selected content item, and the corresponding digital media renderer receives and reproduces the selected content. | 09-09-2010 |
| 20110047231 | APPARATUS AND METHOD FOR STORING CONTENT FLIP LIST OF DIGITAL MEDIA SERVER USING USER INPUT FEEDBACK - Provided is a method for storing a content flip list of a digital media server using user input feedback. The method includes receiving a content request message from a user and transmitting the received request message to a media server, converting information received as a response to the request message into a page format, defining the converted information as a current page, and receiving and storing previous and next pages of the current page, and outputting the received current page through an output part. | 02-24-2011 |
