| 20110082617 | IMPACT SIGNAL PROCESSOR FOR FRONT IMPACT ACCELERATION SENSOR - The present invention features an impact signal processor. In preferred aspects, the impact signal processor comprises a first speed signal detection unit detecting a first speed signal of a vehicle using acceleration sensor data provided from an ACU (Airbag Control Unit) sensor, a second speed signal detection unit detecting a second speed signal of the vehicle using acceleration sensor data provided from a FIS (Front Impact Sensor) sensor, a phase lead unit, and a front impact speed estimation unit. | 04-07-2011 |
| 20110068299 | METHOD OF FABRICATING NANO COMPOSITE POWDER CONSISTING OF CARBON NANOTUBE AND METAL - The present invention features in preferred aspects a method of fabricating nano composite powder consisting of carbon nanotubes and metal matrix powder is disclosed. The method includes a low-speed milling process of milling and mixing the carbon nanotubes and the metal matrix powder, and a high-speed milling process of milling the carbon nanotubes and the metal matrix powder which are homogenously mixed in the low-speed milling process to homogenously disperse the carbon nanotubes in the metal matrix powder. In certain preferred aspects, the method can prevent damage of the carbon nanotube and can homogenously disperse the carbon nanotubes in the metal matrix. | 03-24-2011 |
| 20100286442 | NOVEL METHOD FOR PREPARING PREGABALIN - The present invention relates to a method for preparing pregabalin ((S)-3-(aminomethyl)-5-methylhexanoic acid which is useful for the prevention and treatment of seizure disorders, pins, and psychiatric disorders. According to the present invention, pregabalin can be prepared in a high enantiomeric excess of 99% or more, without an additional step of separating or purifying its enantiomer. | 11-11-2010 |
| 20100235703 | COMMUNICATION METHOD USING CODE PACKET IN WIRELESS NETWORK - The present invention, in preferred aspects, provides a communication method using a network coding packet in a wireless network, with reduced occurrence of negative acknowledgements, between a access point and plural mobile terminals. In preferred embodiments of the present invention, a communication method using a network coding packet in a wireless network comprises: (a) transmitting plural downlink multicast packets, each containing serial numbers of packets, to the first and second mobile terminals sequentially; (b) receiving a first negative acknowledgement from the first mobile terminal; (c) receiving a second negative acknowledgement from the first mobile terminal or the second negative acknowledgement skipping the first negative acknowledgement on occurrence of the first packet error at the second mobile terminal; and (d) transmitting a restoration packet containing exclusive OR packet of all errored packets in the restoration period defined in reference to the second negative acknowledgement from the first and second mobile terminals. | 09-16-2010 |
