20110138224 | METHOD AND SYSTEM FOR TRACEPOINT-BASED FAULT DIAGNOSIS AND RECOVERY - A system for tracepoint-based fault diagnosis and recovery includes: a system state tracing model unit for storing state tracing models which are obtained by a modeling technique and are required for fault diagnosis and recovery; a state diagnosis unit for determining whether or not an action event is executable with reference to the state tracing models when the action event is received from a specific tracepoint among multiple tracepoints which exist in each of components within an operating system of the system, and generating a fault recovery command when it is determined that the action is not executable, that is, a fault has occurred; and a fault recovery unit for performing a fault recovery processing based on the state tracing models in response to the generated fault recovery command. | 06-09-2011 |
20130022866 | CARBON-COATED LITHIUM IRON PHOSPHATE OF OLIVINE CRYSTAL STRUCTURE AND LITHIUM SECONDARY BATTERY USING THE SAME - Disclosed is lithium iron phosphate having an olivine crystal structure, wherein the lithium iron phosphate has a composition represented by the following Formula 1 and carbon (C) is coated on the particle surface of the lithium iron phosphate containing a predetermined amount of sulfur (S). | 01-24-2013 |
20130029226 | LITHIUM IRON PHOSPHATE OF OLIVINE CRYSTAL STRUCTURE AND LITHIUM SECONDARY BATTERY USING THE SAME - Disclosed is lithium iron phosphate having an olivine crystal structure wherein carbon (C) is coated on particle surfaces of the lithium iron phosphate, wherein, when a powder of the lithium iron phosphate is dispersed in water, water is removed from the resulting dispersion and the resulting lithium iron phosphate residue is quantitatively analyzed, a ratio of the carbon-released lithium iron phosphate with respect to the total weight of the carbon-coated lithium iron phosphate is 0.005% by weight or less. Advantageously, the olivine-type lithium iron phosphate is not readily separated through uniform thin film coating on the surface of the lithium iron phosphate and exhibits superior conductivity and density, since carbon is coated on particle surfaces of lithium iron phosphate in a state in which the amount of carbon released in water is considerably small. | 01-31-2013 |
