20090140843 | METHOD FOR PROVIDING RADIO FREQUENCY IDENTIFICATION APPLICATION INTERFACE AND SYSTEM THEREOF - The present invention relates to an RFID application interface method and a system thereof. In the present invention, an RFID middleware system changes a control request input from a user or an RFID application system according to a communication protocol of an RFID device to be controlled, and sends it to the RFID device. Also, when the user or the RFID application system inputs a data process policy that is common to various RFID devices of a logical RFID device group, the RFID middleware system generates data process rules that are suitable for communication capability and data processing capability of each RFID device based on the data process policy and provides an interface that allows processing of data by a corresponding RFID device. In addition, the RFID middle system defines a procedural flow of at least one of services and at least one of tasks that constitute an RFID business process and provides an interface to support interconnection and cooperation of services that are included in the RFID business process. | 06-04-2009 |
20100013638 | APPARATUS AND METHOD FOR MANAGING PRODUCT DISTRIBUTION USING SECURITY TAG - Provided is a method and apparatus for managing a product distribution. The product distribution management method may include: reading a security key of a product from a security tag attached to the product; transferring the read security key to a security server; receiving, from the security server, first authentication information that is encrypted using the security key; receiving, from the security tag, second authentication information that is encrypted using the security key; and determining whether the security tag is duplicated, based on the first authentication information and the second authentication information. | 01-21-2010 |
20100214067 | APPARATUS AND METHOD FOR LOCATING RFID TAG - Provided are a Radio Frequency Identification (RFID) tag and apparatus and method for locating a RFID tag without comparing arrival times of blink signals transmitted from the RFID tag in order to quickly trace a location of the RFID tag. The RFID tag includes a tag ID generator configured to generate a tag ID of the RFID tag, a blink generator configured to generate a plurality of sub-blink signals that form the blink signal, a sub-blink ID generator configured to generate sub-blink IDs for the generated sub-blink signals, a sub-blink ID inserter configured to insert the generated sub-blink IDs into the sub-blink signals, and a transmitter configured to transmit the blink signal having the tag ID and the sub-blink IDs. | 08-26-2010 |
20110095869 | METHOD AND APPARATUS FOR REAL TIME LOCATION TRACKING USING RFID - Proposed are a method and apparatus for real-time location tracking using Radio Frequency Identification (RFID), the apparatus including: a first reception information receiver to receive first reception information of a tag signal from a plurality of RFID readers that receives the tag signal from an RFID tag; a reader group generator to select, from the plurality of RFID readers, at least three RFID readers based on the first reception information and generate an RFID reader group including the selected at least three RFID readers; and a location calculator to calculate a location of the RFID tag based on first reception information that is received from the at least three RFID readers included in the RFID reader group. | 04-28-2011 |
20110122926 | APPARATUS AND METHOD FOR GENERATING PSEUDO NOISE CODE - An apparatus and method of generating a pseudo noise (PN) code is provided. The apparatus for generating the PN code includes: a memory device unit including a plurality of memory devices; an exclusive-OR (XOR) operation unit receiving output values of at least two memory devices among output values of the plurality of memory devices to output an XOR operation value with respect to the received output values; and a PN code generation unit generating the PN code based on an output value of the XOR operation unit. | 05-26-2011 |
20120032844 | REAL-TIME LOCATION TRACKING APPARATUS AND METHOD USING GLOBAL POSITIONING SYSTEM (GPS) SIGNAL RELAY TAG - Real-time location tracking apparatus and method using a global positioning system (GPS) signal relay tag is provided. Here, a tag may receive a GPS signal and transmit the received GPS signal to a reader, and the reader may calculate a location of the tag, and thereby a real-time location tracking service may be provided. | 02-09-2012 |
20120086599 | SYSTEM AND METHOD FOR INDOOR LOCATION TRACKING USING PSEUDO GPS SIGNAL TRANMSITTER - To track the location of a terminal in an indoor space by using a pseudo GPS signal transmitter, a GPS signal sent from an artificial satellite is received, and a clock signal of the artificial satellite is extracted from the received GPS signal to perform synchronization with the artificial satellite. Once synchronization with the artificial satellite is performed, a pseudo GPS signal is generated, and the transmission time of the pseudo GPS signal is controlled. The GPS signal is sent to the terminal located in the indoor space by a plurality of transmitting antennas based on the controlled transmission time, thereby enabling the terminal located in the indoor space to track its location. | 04-12-2012 |
20130087610 | TOTAL HISTORY MANAGEMENT SYSTEM AND METHOD USING RADIO FREQUENCY IDENTIFICATION (RFID) TAG AND BARCODE - Provided is a total history management system and method using a radio frequency indentification (RFID) tag and a barcode, which may efficiently manage individual products using a barcode and an RFID tag that may provide environmental information for management of the individual products. | 04-11-2013 |
