20100296097 | SCANNING OPTICAL MEASUREMENT APPARATUS HAVING SUPER RESOLUTION - Provided is a scanning optical measurement apparatus having super resolution. The scanning optical measurement apparatus includes: a light source; a first lens, which focuses light irradiated from the light source; a first pin hole, which is disposed next to the first lens; a second lens, which diverges light that passed through the first pin hole; a scanning unit, which scans light that passed through the second lens; a first beam splitter, which is disposed between the second lens and the scanning unit; an object lens, which focuses light that passed through the scanning unit on the subject; a slide, where the subject is placed; an optical probe, which reflects the light that passed through the subject after being irradiated from the light source; a second beam splitter, which is disposed between the scanning unit and the object lens; a first optical detector, which detects the light that passed through the first beam splitter after being reflected from the subject and the optical probe; a second pin hole, which is disposed between the first beam splitter and the first optical detector; and a second optical detector, which detects light that passed through the second beam splitter after being reflected from the subject and the optical probe. | 11-25-2010 |

20140149078 | PERFORMANCE MEASUREMENT UNIT, PROCESSOR CORE INCLUDING THE SAME AND PROCESS PROFILING METHOD - A performance measurement unit includes an event counter configured to record a counter value indicating a number of events occurring in a processor core, and a shadowed event counter configured to copy the counter value recorded in the event counter to the shadowed event counter. The performance measurement unit is configured to determine a number of effective events occurring in the processor core using the event counter and the shadowed event counter. Effective events correspond to events occurring when a selected process is executed. | 05-29-2014 |
20140149968 | DYNAMIC LIBRARY PROFILING METHOD AND DYNAMIC LIBRARY PROFILING SYSTEM - A dynamic library profiling method and a dynamic library profiling system including writing a first break point instruction at a start address of a dynamic library function, recording a first event count value that is a process performance management unit (PMU) count when a target process executes the first break point instruction, writing a second break point instruction to a return address of the dynamic library function, and calculating a PMU count generated in a processor core while the dynamic library function is executed, by comparing the recorded first event count value with a second event count value that is a process PMU count when the target process executes the second break point instruction, wherein the process PMU count is a cumulative value of PMU counts generated in the processor core while the target process is executed. | 05-29-2014 |

20140233599 | NANOLASER GENERATOR USING GRAPHENE ELECTRODE AND METHOD FOR MANUFACTURING THE SAME - The present disclosure relates to a nanolaser generator using a transparent graphene electrode, a method for manufacturing the same, and a single nanopillar LED using the same. The nanolaser generator includes a microdisk resonator, a protruding dielectric ring provided to surround a boundary surface of the microdisk resonator, an external dielectric ring provided at an outer side of the microdisk resonator, and a transparent graphene electrode provided at upper surfaces of the microdisk resonator, the protruding dielectric ring and the external dielectric ring. Therefore, the processes required for generating a nanolaser may be reduced by half in comparison to a general technique, and a nanolaser may be generated just with a micro current. | 08-21-2014 |
