Abstract:
A beacon scheduling method of a router by a coordinator in a network system that includes the coordinator and at least one router, includes receiving an allocation request signal of a time period in which a beacon of the router is transmitted; determining the time period to be allocated to the router based on information relating to a time period allocation state; and transmitting information relating to the determined time period to the router. The beacon slots can be efficiently allocated and managed when the ZR joins or leaves the network. Therefore, it is possible to effectively prevent the beacon collisions between ZRs over the network.
Abstract:
A juice extraction module for a juicer is provided, which includes a container formed with a juice discharge port, a sieve positioned inside of the container, a screw positioned inside of the sieve to extract juice from a material, and a lid coupled to a top end of the container and formed with a input port through which the material is input. The juice extraction module includes a crushing portion formed on a top end of the screw to be narrowed upward, the crushing portion having a crushing blade formed thereon; and a crushing processing portion connected to the input port and formed in a bottom of the lid to be concave for accommodating the crushing portion.

Abstract:
A method and apparatus for detecting a radar signal is provided. The method includes collecting a plurality of pulses based on a reference time or a reference pulse collection count, classifying the plurality of pulses into groups based on similarity of pulse widths, classifying the groups into a short-pulse type and a long-pulse type and calculate the number of groups in each type, and determining whether a radar signal exists based on a number of groups in each type.
Abstract:
Disclosed herein is a method for fabricating a three-dimensional ultrafine conducting polymer wire having a high aspect ratio by local chemical polymerization using a micropipette. The fabricating method includes the steps of: (a) disposing a lower end of the micropipette, filled with an aqueous monomer solution corresponding to a conducting polymer, over a surface of a substrate at an alignment point at which the ultrafine conducting polymer wire is to be formed; (b) bringing the lower end of the micropipette into contact with the surface of the substrate at the alignment point; (c) drawing the micropipette away from the surface of the substrate by a predetermined distance to form a meniscus of the aqueous monomer solution between the lower end of the micropipette and the surface of the substrate; and (d) moving the micropipette in a growth direction of the ultrafine conducting polymer wire at a constant speed such that the meniscus is grown into the ultrafine conducting polymer wire having a high aspect ratio by a polymerization reaction of the meniscus with oxygen in the air.
Abstract:
Discussed are a diagnostic cartridge and a control method for the diagnostic cartridge. The cartridge includes a sample port through which a sample is injected, a first chamber moving the sample injected from the sample port, a second chamber moving a substrate solution, a first membrane formed at a distal end of the first chamber to function as a valve for preventing other substances from being injected into the first chamber after the sample is completely moved, and a second membrane formed at a distal end of the second chamber to function as a valve for preventing other substances from being injected into the first chamber after the substrate solution is completely moved.
Abstract:
Disclosed is a micro-fluidic system including a lower substrate, an upper substrate formed opposite to the lower substrate and formed with an air injection path, and a micro-fluidic device interposed between the upper and lower substrates, wherein the micro-fluidic chamber includes a fluid chamber filled with a fluid and the fluidic chamber is physically connected to the air injection path.
Abstract:
A liquid crystal display device having an improved electrostatic discharge structure includes: a liquid crystal panel on which an image is formed; a light emitting diode (LED) unit for irradiating a backlight to the liquid crystal panel; a chassis in which the liquid crystal panel and the LED unit are installed; a LED circuit board including a LED chip that is installed to electrically contact the chassis and to control the LED unit; and a main circuit board connected to the liquid crystal panel and the LED circuit board. A grounding line is connected to the main circuit board and is formed on the LED circuit board. Accordingly, the static electricity that has flowed from the outside through the chassis 10 may be immediately discharged through the grounding line, and electronic components in the liquid crystal display device may be protected from the static electricity.
Abstract:
A communication apparatus includes an antenna which receives data frames from transmitters; at least one correlator, each of which is associated with a single identification code and detects a frame corresponding to the identification code from the data frames; and a reserved correlator which detects an acknowledge (ACK) frame from the transmitters corresponding to at least one correlator.
Abstract:
In a communicating system including a base node, at least one adjacent node, and a start node transmitting data requested by the base node via the adjacent node or to the base node, data requested to the start node is transmitted by measuring a power required for data transmission between the nodes forming the communication system, selecting a path one by one depending on a minimum power consumption required for the data transmission from the base node to the start node using the measured power, and transmitting the requested data using the selected path.
