This study focuses on a three-dimensional measurement system of components on a printed-circuit-board (PCB). Most existing methods for automatic optical inspection face the problem of light reflecting on components. We herein propose a new method to restore the reflection area of components with the aim of measuring their shape accurately. This method use a pattern projection system along with an algorithm for restoring the components’ reflection area. For efficient restoration of the restore reflection area, the reflection regions are first identified through pixel resolution, wherein, saturated pixels represent the reflection regions. Then, the PCB components are tilted slightly using solder. These characteristics are used to, obtain the rotation matrix of a component, and its reflection area is restored. The performance of the proposed method is evaluated through a series of experiments, whose. results demonstrate its effectiveness.

This paper presents a distributed estimation scheme for determining the geometric center of multiple targets by a group of agents in 2-dimensional space. These agents have the knowledge of bearing measurements to a part of the targets and communicate with each other. Specifically, we utilize a continuous-time dynamics with strong coupling among agents to process local information. This approach allows us to assign the equilibrium point of the dynamics describing collective behavior of the agents to the geometric center of the targets. The benefits of this approach include: (i) no initialization process is required and (ii) global information, such as the numbers of targets and agents, is not required. These properties make the proposed estimation method suitable for plug-and-play operation.

If the movement of the hand is dataized, it can be applied and used in various fields such as operating drones, vehicles, and the prosthetic arms. In this study, hand movements were recognized using electromyography sensors, inertial sensors and pressure sensors and used for mouse control that can be universally applied in various fields. A device is capable of implementing four functions: left-click, right-click, cursor movement, and wheel scroll was designed and developed. The data obtained through the sensors were stabilized through a low-pass filter and then linked to a PC through Bluetooth communication for the mouse functions and accuracy. Accuracy of functions is 96% for left-click, 70% for drag, 76% for right-click, 79% for wheel scroll. Accuracy of right-click is upgraded by changing electromyography sensor to pressure sensor.
