Abstract

Many incidents happen in football matches such as injury, fight between team and ball out of game as whistle is blow. The worst case is where the ball exploded as the ball kick simultaneously from two opposite directions. To reduce problem in football matches and ensure the quality of the football match specification, this project is proposed a conveyor system for football quality checking, focusing on the ball size and weight measurement. In the conveyor system, a conveyor belt is introduced as a medium for conveying the ball, sensors to check the football specification and microcontroller to read the sensor input and produce output in term of motor control and measurement display. The conveyor system is made for checking the FIFA standard ball specification and it was built portably for easily carry and used in sport shop. The system could operate automatically, thus reducing to the need for worker. This project is expected to reduce injury in football match and also ensure the quality of the ball is guaranteed. For a standard football size measurement, the ball weight shows almost similar to the standard specification with 20g differences.

Abstract

This paper presents study on optimizing RF signal detection and alert system for restricted area. Nowadays, mobile phone utilization is very common among youngsters. Despite of being very useful for educational purpose, it turns into a noteworthy issue while being smuggled into restricted area, such as examination hall and used as a cheating tool. To overcome this problem, an advancement on the detection and alert system of active mobile phone was proposed by implementing RF signal detection system optimization using multi-band dipole antenna and alert system utilizing LED and camera. The system demonstrated higher sensitivity to 3G signal followed by GSM and Wi-Fi with the decrease in voltage value across the LED when distinguishing 3G, GSM and Wi-Fi signal with the estimation of 2.316 V, 1.162 V and 1.054 V respectively. The alert system was improved by activating LED and camera instead of buzzer in displaying the region of the active mobile phone. The camera was able to effectively capture the conceivable cheating area when active mobile phone is present. The images of the potential cheating region can be recovered from the computer. This framework can assist the invigilators with being cautioned to the potential regions of cheating using mobile phone.

Abstract

This paper presents a study on bending and rotational properties of two-chambers soft actuator for underwater application. Previous study demonstrated the actuator characteristics required to optimize the bending performance and its potential to perform underwater because of the actuator material. However, there is less study of the actuator performance underwater as well as how the actuator tips rotating during actuator bending motion. In this paper, three tests have been proposed which are comparisons of bending angle simulation and experiment in air environment, bending angle performance in air and underwater environment as well as rotational angle of actuator tip in air environment. The bending angle of soft actuator is measured based on displacement in horizontal and vertical axis and for rotational angle, gyro sensor has been used. Based on the analysis, it is proven that the fabricated soft actuator performs almost similar trend to the simulation. It is also demonstrated that the actuator performs almost double bending motion underwater environment compared to in air environment at the same pressure, and the actuator is able to rotate 90ยบ in air environment with the supplied pressure 52 kPa.
