Abstract: A method of generating a fuse configuration for trimming a circuit includes evaluating characteristics, corresponding to each of a plurality of fuse configurations, of the circuit trimmed based on the plurality of fuse configurations respectively, selecting at least one fuse configuration from among the plurality of fuse configurations, based on a result of the evaluating the characteristics of the circuit, calculating a contribution information by calculating a degree of influence of fuse data of each of the plurality of fuse configurations to the characteristics of the circuit, based on the plurality of fuse configurations and the characteristics, and generating at least one new fuse configuration, based on the selected at least one fuse configuration and the contribution information.

Abstract: A composition for surface treatment includes fluorosilicic acid (H2SiF6) and hydrofluoric acid (HF), and/or a surface treatment method using the same. The composition may be used to treat (e.g., etch) a substrate such as glass or the like.

Abstract: A parking management system including a rail is described. A camera module takes images of a parking area, has a chargeable battery, and moves along the rail using a motor and wheels. A charging and AP module charges the camera module, receives image information from the camera module, and is movable using a motor, a running rail and gears. A server processes the image information received from the charging and AP module. A computer is connected to the server, and contains management software which executes a parking situation search using a database of the server. The camera takes images from the parking area while moving along the rail, and is positioned on the charging rail so as to be charged from the charging and AP module.
