20140210118 | POLYMER OR POLYMER COMPOSITE MEMBRANE HAVING THROUGH-THICKNESS MICROPORES, AND METHOD FOR PREPARING SAME - A polymer or polymer composite membrane having through-thickness micropores and a method of preparing the same are provided. More particularly, a polymer or polymer composite membrane having a pore structure such that micropores are aligned in a mesh structure in the thickness direction of the polymer or polymer composite membrane due to unidirectional freezing in the thickness direction of a solvent. The membrane has through-thickness micropores, and thus has improved permeability in the thickness direction and superior uniformity in size of the micropores and wall thickness between the micropores. For these reasons, the membrane can be used for a porous membrane substrate, microfiltration membrane, etc. | 07-31-2014 |
20110252129 | APPARATUS AND METHOD FOR REGISTERING NODE AND SEARCHING FOR FLOATING INTERNET PROTOCOL ADDRESS USING DISTRIBUTED NETWORK - A method of registering a new node in a network and a method of searching for a floating Internet Protocol (IP) address through a distributed network are provided. The method of searching for the floating IP address may include receiving, by a representative node of a head network ring, from an external node, a message comprising an Identification (ID) of a target node, determining whether the ID of the target node is registered in the head network ring, based on a ring information table, and transferring the message to a representative node of a child ring having an address range of the target node among child rings, when the ID of the target node is not registered in the head network ring. | 10-13-2011 |
