Abstract:
PURPOSE: A multi-hop resource reservation method on the wireless sensor network is provided to minimize overhead in a multi-hop reservation process by giving payload of a control packet for efficient multi-hop resource reservation. CONSTITUTION: A source node transmits an MSRQ(Multi-hop Slot Reservation reQuest) message about a relay node(S700). A destination node receives a relayed MSRQ message through the relay node(S710). The MSRQ message includes a plurality of slot information. The destination node generates an MSRP(Multi-hop Slot Reservation rePly) message(S720). The destination node transmits the MSRP message to the source node through the relay node.
Abstract:
PURPOSE: A magnetic resonance induction type wireless power transmission apparatus is provided to prevent the waste of energy by cutting off power supply when sensing foreign materials. CONSTITUTION: A power converting unit of a wireless power transmission apparatus comprises an oscillator(121) which creates a signal with a fixed frequency, a power amp(122), a matching network(123), and a current sensor(124) which is connected between the matching network and a transmission antenna(110) and measures current transferred from the matching network to the transmission antenna to sense current changes.
Abstract:
PURPOSE: A routing route establishment method and computer readable recording medium are provided to establish one or more routing routes through the transmission route of a participation request message and the reception route of a node address. CONSTITUTION: A new node transmits cluster participation request messages to a cluster head of specific cluster(S716). The cluster head allocates a node address within a cluster for the new cluster by responding to the cluster participation request message(S740). The cluster transmits the node address to the new node. The new node participates in the specific cluster by using the received node address(S746). The transmission route of the participation request message or the reception route of the node address is established as the routing route(S770).
Abstract:
PURPOSE: An automatic motion sequence diagram generating device is provided to efficiently determine problems by indicating a mutual cooperation process as a sequence diagram during the development of a component based program or debugging. CONSTITUTION: A component information storage(310) receives and stores the type of component information from an application program or a framework. A component log storage(320) stores the operation log and time information between the component and the application program or between the components. A sequence diagram generator(330) automatically generates a sequence diagram script and displays the same, based on the component information and a motion log information.
Abstract:
PURPOSE: A beam forming array antenna control system and a beam forming method using the same are provided to implement beam forming communication by controlling the number of antenna arrays. CONSTITUTION: A beam radiation control part(110) controls beam radiation for beam searching to each sector region so that the initial beam is transmitted from signal transmission units of predetermined two antennas. A beam receiving part(120) receives response beams corresponding to the beam radiated from the signal transmission unit of each antenna to the sector region. A sector selection part(130) detects a sector corresponding to the response beam having the largest intensity among the response beams received in the beam receiving part and transmits information on the sector to the beam radiation control part, thereby radiating a beam to the optimized sector.
Abstract:
PURPOSE: A pitch estimating system of a time-frequency combining area using salience and a method thereof are provided to estimate a pitch using salience of a frequency domain. CONSTITUTION: An autocorrelator(110) calculates an autocorrelated value of a time domain about a voiced sound signal. A salience detector(120) detects salience of a frequency domain about the voiced sound signal. A pitch estimator(130) applies a first weighted value to the salience and the autocorrelated value in the time domain. The pitch estimator combines the autocorrelated value with the salience. The pitch estimator estimates an index of the maximum peak of the combined signal as a pitch.
Abstract:
PURPOSE: An audio processing apparatus and a method thereof are provided to decode audio files of a multi-layer structure by decoding audio files of a single-layer structure. CONSTITUTION: A header of audio files is analyzed. The kind of audio data includes in the audio files is recognized(S210). An essential header is recognized with reference to prestored core-layer data which is included in the audio files(S230). The recognized essential header is generated(S240). The core-layer data is separated from the multi-layer data(S250).
Abstract:
PURPOSE: A robot designing apparatus and a method thereof using a pop-up primitive mode are provided to easily design a joint part which connects each component of a robot. CONSTITUTION: An input unit(10) inputs a selection signal of a user. A component design unit(41) designs a first component of a robot according to the selection signal of the user through the input unit. The component design unit designs a second component in a pop-up mode. A joint design unit(43) selects a connection mode of a joint, an operation range, or an eccentricity range according to the selection signal of the user.
Abstract:
PURPOSE: A sunlight and LED combination lighting system and an operating method thereof are provided to implement proper illumination in a desirable space by integrating sunlight illumination and LED illumination. CONSTITUTION: A light collecting unit(10) collects sunlight. A light connecting unit(20) connects the collected light to an optical fiber. A light transmitting unit(30) is connected to a light connecting unit. The light transmitting unit transmits the collected light to a preset space. A lighting unit(100) includes a sunlight illuminator and an LED illuminator. The LED illuminator emits light with the controlled brightness.
