Publication number: 20140152489Abstract: A method of reusing a frequency by allocating two orthogonal signal waveforms to the same frequency band is as follows. Two high-frequency ocean surface radars can be operated in the same frequency band without mutual interference by allocating a signal having an up-chirped LFM waveform and a signal having a down-chirped LFM waveform, having the same frequency band, to the two radars by employing an orthogonal characteristic between the two signals. Furthermore, a plurality of radars located within a distance within which interference is possible can be operated without mutual interference by combining and allocating two orthogonal signals and a plurality of frequency bands.Type: ApplicationFiled: April 25, 2013Publication date: June 5, 2014Applicants: Hannam University Institute for Industry-Academia Cooperation, Electronics and Telecommunications Research InstituteInventors: Electronics and Telecommunications Research Isntitute, Hannam University Institute for Industry-Academia Cooperation

Patent number: 7157402Abstract: The present invention provides a bimodal porous carbon capsule with a hollow core and a mesoporous shell structure, which can be employed as an electrocatalyst support for a fuel cell; electrocatalysts for the fuel cell using the bimodal porous carbon capsule, and a method of preparing the same. The electrocatalyst according to the present invention has higher catalysis activity as compared with the Pt—Ru or Pt catalyst supported by the conventional carbon black, so that the performance of the fuel cell is enhanced, and it can be easily prepared in an aqueous solution state. According to the present invention, the porous carbon support employed as the support for the catalyst has excellent conductivity and a high surface area, so that the loaded catalyst can be prepared with a smaller amount than that of the conventional carbon black.Type: GrantFiled: August 6, 2004Date of Patent: January 2, 2007Assignee: Hannam UniversityInventors: Jong Sung Yu, Geun Seok Chai, Suk Bon Yoon
