20140158805 | RETRACTOR PRETENSIONER OF SEAT BELT FOR VEHICLE - Disclosed herein is a retractor pretensioner of a vehicle seat belt. The retractor pretensioner of the present invention may prevent an overshoot phenomenon in which residual pressure of gas impedes reverse rotation of a spool when the pretensioner operates as a load limiter. The pretensioner includes a spool around which the seat belt is wound and wherein the spool is rotatably installed in a frame to rotate the spool relative to the frame by gas pressure transmitted from a gas generator to the spool. In addition, the pretensioner includes a valve shaft that is installed in the spool, wherein the valve shaft operates as a rotating shaft of the gas generator with respect to the frame when the gas generator is not operated and as a valve, through which the gas is discharged out of the spool, when the gas generator is operated. | 06-12-2014 |

20100248634 | METHOD OF CYCLIC DELAY DIVERSITY WITH THE OPTIMAL CYCLIC DELAY VALUE, AND TRANSMITTER PERFORMING THE SAME - Disclosed are an apparatus and method of determining an optimal cyclic delay value. The method of determining the optimal cyclic delay value includes determining a Signal-to-Interference and Noise Ratio (SINR) function depending on a diversity order; determining a channel estimation error variance function; and determining an SINR being required for a system according to the SINR function and the channel estimation error variance function. | 09-30-2010 |
20120184232 | METHOD FOR SELECTING SOURCE TRANSMIT ANTENNA IN COOPERATIVE MIMO COMMUNICATION SYSTEM - Disclosed is a method for selecting a source transmit antenna in a cooperative multiple-input and multiple-output (MIMO) communication system including a source node, a relay node and a destination node. The method includes determining a source transmit antenna selection metric such that a source-destination channel, a source-relay channel and a relay-destination channel are related to one another, and selecting a positive integer number of antennas such that the source transmit antenna selection metric is maximized. | 07-19-2012 |
20130114805 | ENCRYPTION SYSTEM USING DISCRETE CHAOS FUNCTION - Provided is an encryption system, which includes: an encryption round calculation unit for encrypting a plain text; and a substitution unit provided at the encryption round calculation unit and having a plurality of S-boxes defined by a discrete chaos function using each of a plurality of key values as a parameter and performing a substitution calculation process to each of words of the plain text divided by the number of the plurality of key values. Since a discrete chaos function becomes a standard for an S-box design and an encryption calculation operation is performed by a plurality of S-boxes, the encryption system may be applied to a system having a small computational complexity. | 05-09-2013 |
