Abstract :-

The main goal of this project is to develop and implement a prototype optical transmission system supporting point-to-point communication link. A free space laser link and a plastic fiber link have been designed and implemented in this present work. Both links have been tested with two data source systems: “PC as a host” and “PIC as a host” by asynchronous serial transmission.

Just up to the maximum speed of serial port that can be offered, 115200 bps, has been tested and is reliable at distances of 30 feet. As a result of this work, wireless laser system was designed and can be used as a direct link between adjacent buildings whereas plastic fiber link in short range communication network architecture without EMI, impossible direct interception and the transmission can be detected by no instrument. Any information in all types of files and any images can successfully transfer by Hyper Terminal and self-developed software through those links.

4. Design of the Temperature Control System of Solar Cell Lamination Machine.

Abstract :-

The temperature control is the key step in the laminating process of solar cell lamination machine. The traditional controlling method is PLC temperature control. The method being used has some shortages such as high price, low control precision, and so on. In order to improve the control precision and its performanceprice ratio, a new control system taking the double microcontroller (MCU) as its core is introduced in this paper. Based upon the system, the expert PID was designed to adjust the requirements of the temperature control. The method can adjust the temperature parameters and establish an accurate laminating temperature under the condition of changing temperature and different control targets. The practical operation results show that the controller has a better robustness and a higher control precision. In addition, it can adapt to an external changing condition, and has a strong anti-jamming capability.

Abstract :-

This paper presents a new approach of maximizing energy harvesting in photovoltaic (PV) systems using bisection search theorem (BST). The fundamental of the BST and its application into maximum power point tracker (MPPT) in PV systems are described.

8. Adding New Functions to the Remote Airfield Lighting System.

Abstract :-

There are many remote airfields that are not connected to the power grid. Providing adequate lighting to these airfields is necessary and challenging. The Federal Aviation Administration (FAA) has sponsored a research project, Remote Airfield Lighting Systems (RALS), through the Center for General Aviation Research (CGAR). The findings from the RALS research specified a light that had low power needs and a color/intensity to meet the requirements for airfield identification and landing. To make these lights more appropriate to wide spread applications, the research team is conducting an exemplary operational test. In this paper, we discuss the new functions added to these lights for the operational test, including both automatically/remotely switching on/off the lights and smart charging of the batteries using solar panels under the control of a microcontroller. In addition, we consider future new functions such as low cost pilot controlled lighting as well as wireless networking for health monitoring and controlling of the lighting system. These new functions can greatly improve the convenience of the usage of RALS while vkeeping the same low cost.

Abstract :-

The localization problem consists in estimating the position of the nodes within the network. This is a crucial issue for location-dependant applications. This paper presents an implementation of a localization scheme based only on the received signal strength (SS) in a Zigbee-based sensor network. This is done by taking advantage of the inherent radio communication capability present in each node. The algorithm is intended for an outdoor environment. It is based in a model, which infers distance between neighboring nodes using the SS. A coordinate system is then derived employing a multidimensional scaling (MDS) technique. The signal power level variability due to ground reflection is approached using Lloyd Effect (from optics) and incorporated in the model.

In recent years, the home environment has seen a rapid introduction of network enabled digital technology. This technology offers new and exciting opportunities to increase the connectivity of devices within the home for the purpose of home automation. Moreover, with the rapid expansion of the Internet, there is the added potential for the remote control and monitoring of such network enabled devices.

Abstract :-

We have designed and implemented a wearable ZigBee-based guidance system in which a main controller collects ultrasound and GPS signals from sensors attached to subcontrollers and provides appropriate directions to a blind person. The signals from the different sources need to be handled separately, which reduces the effective sampling rate, and may impact the quality of the guidance provided. To address this, we propose a new scheduling scheme that interleaves the two signals without collision, based on the on-line estimation of signal handling times. Experimental results show that this scheme increases a sampling rate by up to 71% compared with the simple scheme1.

23.A 2g-rfid-based e-healthcare system.

Abstract :-

Radio frequency identification technology has received an increasing amount of attention in the past few years as an important emerging technology. However, the intrinsically passive features of existing RFID systems, to which we refer as firstgeneration RFID systems, render their adaptation to real-world dynamics in order to efficiently comply with up-to-date application specific requirements difficult. To address this challenging issue, we propose an evolution to second-generation RFID systems characterized by the introduction of encoded rules that are dynamically stored in RFID tags. This novel approach facilitates the systems’ operation to perform actions on demand for different objects in different situations, and enables improved scalability. Based on 2G-RFID-Sys, we propose a novel e-healthcare management system, and explain how it can be employed to leverage the effectiveness of existing ones. It is foreseeable that the flexibility and scalability of 2G-RFIDSys will support more automatic and intelligent applications in the future
