Abstract: The present disclosure relates to an apparatus for controlling a virtual machine in a device. The apparatus comprises a virtualization requesting part and a controlling part. The virtualization requesting part is configured to transmit a first instruction word for controlling the virtual machine to an independent virtualization apparatus. The controlling part is configured to execute an operation corresponding to a second instruction word received from the virtualization apparatus.

Abstract: A device carries out virtualization technology. An apparatus and a method in which an operating system or a program migrates a virtual machine during implementing in the device to a different type of device. The apparatus for migrating the virtual machine in the device may comprise an input unit for requesting the migration of the virtual machine, a display for displaying the migration process of the virtual machine, a virtualization processing unit for creating the virtual machine to run an application corresponding to a plural of operating system and for collecting the data related to the application run through the virtual machine and a controller for transmitting the data related to the application run through the virtual machine to a peripheral device using a different instruction set architecture.

Abstract: Disclosed herein is an ontology-based Electronic Product Code (EPC) automatic conversion method and system. The ontology-based EPC automatic conversion method includes the steps of arranging existing Radio Frequency Identification (RFID) EPC ontology information and newly added EPC ontology information, converting tag data collected from an RFID reader into binary data so as to perform header information extraction and Uniform Resource Name (URN) conversion, extracting the header information of an EPC from the binary data output as a result of the conversion, initializing the ontology properties so as to utilize the EPC ontology, extracting a corresponding code system of the ontology by performing comparison with the header information of the tag data converted into the binary data, extracting the ontology properties from the corresponding code system of the ontology, and performing automatic conversion into URN-type data on the basis of information about the extracted ontology properties.

Abstract: Disclosed herein is a Radio Frequency Identification (RFID) middleware-based sensor data stream processing system and method. The RFID middleware-based sensor data stream processing system of the present invention includes one or more sensors for measuring and collecting surrounding environmental information, sensor nodes for transmitting data collected by the sensors or receiving sensor management commands, a master node for transmitting or receiving data to or from the sensor nodes and for configuring the data received from the one or more sensors into data having a specific protocol structure applied in common to the sensors, and RFID middleware for receiving the sensor data from the master node, converting the sensor data into data of an Electronic Product Code (EPC), and converting the EPC data into data of a Uniform Resource Name (URN) code.
