In this research, we have designed, developed implemented a wireless sensor networks based smart home for safe, sound and secured living environment for any inhabitant especially elderly living alone. We have explored a methodology for the development of efficient electronic real time data processing system to recognize the behaviour of an elderly person. The ability to determine the wellness of an elderly person living alone in their own home using a robust, flexible and data driven artificially intelligent system has been investigated. A framework integrating temporal and spatial contextual information for determining the wellness of an elderly person has been modelled. A novel behaviour detection process based on the observed sensor data in performing essential daily activities has been designed and developed.

The electrical power grid is often referred to as one of the most complex man- made systems on Earth. Its importance to all aspects of our daily lives, economic stability, and national security cannot be overstated, and the need for an updated, secure, resilient, and smarter power grid infrastructure is increasingly recognized and supported by policy makers and market forces.

Identification is pervasive nowadays in daily life due to many complicated activities such as bank and library card reading, asset tracking, toll collecting, restricted access to sensitive data and procedures and target identification. This kind of task can be realized by passwords, bio- metric data such as fingerprints, barcode, optical character recognition, smart cards and radar. Radiofrequencyidentification(RFID)isatechniquetoidentifyobjectsbyusingradiosystems. It is a contactless, usually short distance, wireless data transmission and reception technique for identification of objects. An RFID system consists of two components: the tag (also called transponder) and the reader (also called interrogator).

Radio frequency identification (RFID) is gaining in popularity, especially as we find ourselves in this communications age and headed towards a ubiquitous computing world. Automatic identification systems become an important aspect not just in today’s technology but also as part of our daily life. We need RFID in our cars, transportation systems, access points, and even simple transactions; we also acknowledge the need for RFID in our logistics systems, healthcare, and tracking and locating applications.

If the space around us could adapt to our needs and intentions, then our lives would be much simpler. We would have to spend less time on our daily chores, we would be more productive and, hopefully, we would live in a less worrisome and, most likely, more secure world

Computer science as an academic discipline began in the 1960’s. Emphasis was on programming languages, compilers, operating systems, and the mathematical theory that supported these areas. Courses in theoretical computer science covered finite automata, regular expressions, context-free languages, and computability. In the 1970’s, the study of algorithms was added as an important component of theory. The emphasis was on making computers useful. Today, a fundamental change is taking place and the focus is more on a wealth of applications. There are many reasons for this change. The merging of computing and communications has played an important role. The enhanced ability to observe, collect, and store data in the natural sciences, in commerce, and in other fields calls for a change in our understanding of data and how to handle it in the modern setting. The emergence of the web and social networks as central aspects of daily life presents both opportunities and challenges for theory.

隨著電磁閥在工業和日常應用的增多,其功耗越來越被人們所重視。通過對電磁閥驅動電路的研究,設計一套電磁閥節能驅動電路。不僅提高了電磁閥的響應時間,更重要的是降低了功耗,使電磁閥由工作在大電流狀態下,變成大電流啟動小電流維持的工作狀態。減少了由電流過大引起的電磁閥線圈過熱,增加了電磁閥的安全性。The power consumption of an electromagnetic valve is drawing increasingly more attentiori as it is widely used in industrial production and daily life. In this study, an energy - saving driving circuit of electromagnetic valves was designed. It can make an electromagnetic valve to start with a high current while work with a low current; thereby the power consumption can be reduced. Besides, it can shorten the response time of an electromagnetic valve and improve the security of the valve.

隨著科技的發展，人們在日常生活中使用的電器越來越多，電子設備的電磁兼容性（EMC）也越來越重要。所以，人們對電子設備的電磁兼容性的要求也越來越嚴格，越來越規范。而在市場競爭中，如何降低成本、減少設備體積，是各電子設備制造廠家重點研究的課題。通過對開關電源的EMI濾波電路的類別和相應的技術特點進行分析，設計出一種既能提高性能，又能降低成本的濾波電路。With the development of technology, appliances people use in their daily lives, more and more electronic devices electromagnetic compatibility （ EMC ） has become increasingly important. So, people electromagnetic compatibility requirements of electronic devices have become increasingly stringent, more and more standardized. The competition in the market, how to reduce costs, reduce equipment size, is the subject of the electronic equipment manufacturer focused on research. Through the technical characteristics of the respective category and the EMI filter circuit switching power supply is analyzed both designed to improve a performance of the filter circuit can reduce the cost.
