Abstract: A storage device includes a printed circuit board (PCB) with attached semiconductor chips, each including a memory, and with at least one wire coupling the semiconductor chips. The storage device includes a case including a first case surrounding a top portion of the printed circuit board and a second case surrounding a bottom portion of the printed circuit board. A sidewall of the first case and a protrusion of the second case form a concavo-convex structure. The sidewall of the first case and the protrusion of the second case cover a side of the printed circuit board.

Abstract: Provided are an apparatus for manufacturing a textile grid with increased adhesion and a method thereof capable of integrating the textile grid with a concrete structure by increasing the adhesion of the textile grid when the concrete structure is built, repaired, or reinforced, increasing structural safety and durability of the concrete structure, increasing a working speed by coating a surface of the textile grid with an abrasive material powder that is a surface coating material in an automatic series of processes immediately after the textile grid is manufactured, and increasing coating performance by automatically inspecting and adjusting the amount of the coating material applied to the surface of the textile grid using a camera.

Abstract: An emergency power diagnosis system measures the exact value of impedance voltage (Vis) from an AC actual waveform (VSM) includes circuits and software operable to measure the effective resistance of battery internal impedance to determine the expected life of a battery string. The system is configured to determine the cause of aging progress in advance and determine by unmanned monitoring the real-time status of emergency power system at a remote site.

Abstract: This invention measures the exact value of impedance voltage (Vis) from AC actual waveform (VSM) which includes ripple noise voltage, and suggests the inventive circuits and softwares capable of acquiring the effective resistance of battery internal impedance and the operational algorithm of the diagnosis for the expected life of battery string. In accordance with a series of functional operations and the execution of the program in MPU, this diagnostic system can find the cause of aging progress in advance and settle by unmanned monitoring the healthiness of emergency power system always in real time at remote site.
