Abstract: Disclosed is an apparatus and method for injecting liquid-drops of particle mixture liquid including a mixture of biological particles, affecting magnetic field, and having only positive particles, which are combined with magnetic responsive material, separated by magnetic force, and having negative particles, which are not combined with magnetic responsive material, precipitated by gravity.

Abstract: A capacitor structure includes: a first electrode configured to include a plurality of openings; a second electrode formed in each center of the openings; and a dielectric layer formed to surround the second electrode and fill the openings of the first electrode.

Abstract: A microchannel chip and a dilution method using the same capable of continuously diluting the diverse concentrations of solution by one time fluid injection using the microfluid technology are provided. The microchannels are formed in a plastic chip using the microfluid technology, and a width, a sectional area, or a length of the microchannel is regulated so that the flow rate of a diluted solution (e.g., buffer solution) and a sample (e.g., chemicals or medicament) is controlled. The diluted solution and the specimen are mixed in the mixing channel according to the flow rate, thereby diluting the sample. Such a diluted solution is mixed again with a diluted solution, carrying out the dilution. With the repeated dilution processes, continuously diluted solution is obtained.

Abstract: A communicating method between two processors in a decentralized multi-node exchange system comprising a central processing module for controlling the system by processing events related to a call process, and a signal processing module having a common memory, for transmitting/receiving a signal message generated in the exchange system to/from the central processing module through the common memory. In order to transmit a message through the common memory, the message is transmitted to a message transmitting buffer when the message transmitting buffer is emptied, and an interrupt is generated to a counterpart receiving the message when the transmitting buffer is not emptied. Meanwhile, in order to receive a message, the number of receiving messages is set during a period of time when the interrupt is received or when it is set to receive a message, and a message corresponding to the number of the receiving message is read from the common memory.

Abstract: A data communication method between a master system and multiple slave systems using a serial input/output interface. The master system connects a communication path to a corresponding slave system, and transmits a message and simultaneously receives a message from the slave system during an assigned communication time. When the transmission of the message ends, the master system transmits a final message and when a final acknowledgement message is received, performs a service for the next slave system. Meanwhile, the slave system receives a message transmitted by the connection of the communication path and simultaneously transmits a message to the master system. Further, when a final message is received, the slave system transmits a final acknowledgement message to the master system. Thus, the effective communication between point-to-multipoint can be achieved.
