Abstract:
Two-way broadcast service providing system and method including a media transmission apparatus are provided. The media transmission apparatus includes a data communication interface that receives participant media from at least one participant terminal via a communication network, a media conversion unit that converts the participant media received through the data communication interface in accordance with a broadcast media standard, and a broadcast interface that transmits the participant media converted through the media conversion unit to a broadcast apparatus so that the participant media is included in broadcast contents.
Abstract:
An imaging sensor includes at least one fiber Bragg grating for filtering an image from a subject for wavelength bands, and an imaging device for converting an image transmitted through the fiber Bragg grating into a digital signal.
Abstract:
Provided is a micro robot position detection device. The device includes a micro robot position detection unit that uses a micro robot control parameter to filter a reflected signal of an ultra wide-band impulse radar signal emitted to a micro robot to extract, as a micro robot signal, a natural oscillating frequency signal generated when the micro robot is driven through control of external electromagnetic field, and analyzes the micro robot signal based on a transmission and reception parameter of the ultra wide-band impulse radar signal to calculate position information for the micro robot. Also, the device may further include an image matching unit that receives position information for the micro robot and performs position correction on the received position information based on pre-stored reference image data and the image data.
Abstract:
There are provided a method for setting a sensor node and setting security in a sensor network, and a sensor network system including the same. A setting apparatus scans a near field communication apparatus included in the sensor node to obtain information on the sensor node. The information on the sensor node is transmitted to a gateway, and the gateway connects the sensor node to the sensor network using the received information on the sensor node.
Abstract:
Provided is a method of supporting CoAP-based sensor data transmission between a sensor data collector in a sensor node relay and one or more 6LoWPAN-unsupported sensor nodes. The method includes receiving a CoAP sensor data request message from the sensor data collector, transmitting a CoAP sensor data request message to a corresponding 6LoWPAN-unsupported sensor node by analyzing the received CoAP sensor data request message, and responding to the sensor data collector by creating a CoAP sensor data response message including sensor data received from one or more of the 6LoWPAN-unsupported sensor nodes.
Abstract:
A control device is provided which controls wireless communication linkage between communication devices. The control device includes a communication unit configured to perform wireless communication with first and second communication devices; a user interface unit configured to generate a communication unit active signal according to a control of a user; and a control unit configured to activate the communication unit in response to the communication unit active signal. The communication unit receives communication linkage information for communication linkage between the first and second communication devices from the first communication device and sends the communication linkage information to the second communication device.
