Patent number: 8003815Abstract: The present invention provides a method of preparing a cross-condensed compound of an amino-acid derivative and (aminoalkyl)trialkoxysilane using microwave, including: irradiating and heating an amino-acid derivative and (aminoalkyl)trialkoxysilane in a microwave reactor to obtain a reaction product (step 1); and refining the reaction product obtained in the step 1 by removing an unreacted solid material from the reaction product and then leaving the reaction product at room temperature under vacuum to remove excess (aminoalkyl)trialkoxysilane therefrom (step 2). According to the method, since a cross-condensation reaction is performed using microwave, unlike a conventional condensation reaction, economic efficiency is increased due to no catalyst, short reaction time and no solvent. Further, the yield and selectivity of products is increased, and the condensation reaction can be environment-friendly performed because a solvent which can badly influence the environment may not be used.Type: GrantFiled: February 22, 2008Date of Patent: August 23, 2011Assignee: Inha-Industry Partnership InstituteInventors: Ik Mo Lee, Dong Hwan Lee, Ho Sub Kim, Sang Eon Park

Patent number: 7990310Abstract: Disclosed herein is an Ultra-WideBand (UWB) ranging method using a narrowband interference suppression waveform. A transmission signal is transmitted to a target object. The transmission signal, reflected from the target object, is received. A template signal is generated by combining the narrowband interference suppression waveform and a channel estimation signal together. A correlation output signal is generated by convoluting the template signal and the received signal. A distance is calculated using a time delay when the correlation output signal has the maximum value thereof. The narrowband interference suppression waveform is any one of two waveforms that are expressed by the following Equation: wr1(t)=g(t??1/2)+g(t+?1/2) wr2(t)=g(t??2/2)?g(t+?2/2) where g(t) is a basic UWB pulse waveform, ?1=(N+1/2)f1, ?2=(N)/f1, N is an integer, and fi is the center frequency of a narrowband interference signal.Type: GrantFiled: April 10, 2008Date of Patent: August 2, 2011Assignees: Inha-Industry Partnership Institute, Samsung Electronics Co., Ltd.Inventors: Kyoung Seop Kwak, Weihua Zhang, Wooshik Kang
