In this paper, we propose a wireless battery charging system which the power transfer position can be automatically moved to the optimal charging placement. The proposed charging system is based on the electromagnetic inductive power transfer technique which is a short distance power transfer system. As a result, we have successfully finished the implementation of the proposed wireless battery charging...
This paper proposes an in-vehicle power line communication (PLC) system which provides an in-vehicle communication for the video and vehicle messages transmission as a reliable alternative networking medium. The proposed in-vehicle PLC system adopts an existing in-vehicle 12-V battery power system, which means we don't need an external DC power supply for in-vehicle communication equipment to achieve...
This paper proposes a wireless router based on Zigbee networks for home automation systems applications, which is capable of smart devices monitoring, controlling, and enabling.

Then this smart device can be monitored and controlled. Moreover,...
This paper proposes a LoRa-based LPWAN vehicle diagnostic system, called i-car system, for driving safety. The proposed i-car system consists of a remote diagnostic system, a LoRa gateway, and a cloud platform. The remote diagnostic system in a vehicle includes a LoRa module, an Arduino (Uno), and an OBD-II bridge. The OBD-II Bridge can read some vehicle information to detect whether is abnormal (like...
This paper proposes a cargo management system, named i-Logistics, which consists of an electronic tape (e-tape), a QR code scan APP, an in-vehicle infotainment system (a vehicular telematics device), and a cloud-based platform. The dedicated Polyvinylidene fluoride (PVDF) sensors are mounted on the electronic tape for monitoring cargos. The QR code scan APP is used to burn a matching dedicated ID...
In this paper, we propose a low-cost Zigbee network based multi-application sensor, which is capable of door open/close and water leakage detection for smart homes. The proposed multi-application sensor consists of a MCU, a tamper switch for anti-theft, and a water-leak switch for detecting water leakage or a reed switch for opening/closing door. We design a unique firmware program executing on the...
In this paper, we develop and put into practice an automatic optical inspection (AOI) system based on machine vision to check the holes on a printed circuit board (PCB). We incorporate the hardware and software. For the hardware part, we combine a PC, the three-axis positioning system, a lighting device, and charge-coupled device cameras. For the software part, we utilize image registration, image...
The Network Management Center needs to be highly intelligent to control the network devices for Quality of Service (QoS) assurance. To make sure the traffic of the call and the data as well as the satisfaction from the customers, we develop a decision support (DS) mechanism for the 4G mobile networking with QoS awareness. In this study, real experimental results are explored from the WiMAX equipment...
This paper proposes a drowsiness-fatigue-detection (DFD) system for improving road safety, which consists of a wearable smart glasses, an in-vehicle infotainment system (a vehicular telematics device), an automotive diagnostic bridge, and a cloud-based platform, etc. The proposed DFD system can real-time detect driver's state for drowsiness or fatigue. When detecting drowsiness or fatigue situation...
Being able automatically recognize the driving style is a very important and challenging task with many practical applications, including insurance. Note that hand labelling of the driving trajectories represents a very timeconsuming task. To overcome this problem, we can reduce thousands of variable-length trajectories to the traditional rectangular format, using quantile-based technique. After that...
This paper proposes a multi-protocol automotive gateway, which supports three popular communication protocols, CAN bus, Wi-Fi, and RS-232. The proposed gateway is implemented on an embedded Linux system ported to an ARM development board. A dedicated application is designed to deal with the information exchange among the ports of the gateway. An ACL is implemented to control the permission of data...
In this paper, a web-based online cooperation training scheme, which utilizes the google online services and applications as students' collaborative learning environment training materials for vocational high school's project-based learning courses is presented. As a result, students can learn how to collaborate a project by google on-line services that can be more efficient achievement in all project...
Today, there is an increase in the number of elderly people who want to start using computers and the Internet. However, elderly people are hindered by limited education, limited knowledge of digital information, words they do not know, and not knowing how to use the computer keyboard and mouse. The setbacks and frustration they face in learning to use the computer causes them to feel computer anxiety...
A multichannel wireless mesh network is composed of wireless routers with multiple radio interfaces operating on non-overlapping channels. It provides a network backbone to support multi-hop connectivity between wireless users and the Internet gateways. However, robustness is a critical issue in such networks because wireless links could be prone to error. Simulation results show that the proposed...
This paper presents an adaptive residential renewable energy management scheme considering end-users' life style to optimize electricity consumption including renewable resources in the smart homes. The proposed scheme generates smart residential power schedules dynamically according to the real-time stock of renewable resources and user-specific life style in home energy management. Experimental...
This paper presents an emergency assistance system for helping deaf-mute people or elderly singletons, called iHelp, which is a real-time emergence reporting mobile devices application software in smart phone. The proposed system not only assists deal-mute people or elderly singletons in the shortest possible time to report, the report also uses SMS intimate to achieve offline report.
This paper proposes an intelligent vehicular telematics platform, which consists of an in-vehicle device connecting the CAN bus with an ODB-II bridge construction, and a mobile application software on smartphone for vehicle driving safety. The proposed platform can real-time monitor vehicular information (such as vehicle engine speed, oxygen, speed per hour, and water temperature), which can efficiently...
This paper proposes a hybrid infrastructure construction of multi-functions digital public address (PA) system, which consists of wired and wireless communications architecture.
