1. Abstract The Passive Optical Networks (PON) is the network which is most popular in fiber network access systems. The abstract states the actual concept of Passive optical Network it's importance. It also implies the Definition and explanation of ONT(Optical Network Terminal), ONU, FTTH-BPON and FTTH-GEPON systems in FTTx premises. 2. Objectives The key objectives of the lab are : • Learning Fiber to the home - BPON and Fiber to the home - GEPON systems. • To process the layer 2…

A number of caries detection devices are available in the market today. Each of these is based on a certain underlying physical principle such as X- Rays, Visible light, Laser light, Electrical current and Ultrasound (Pretty, I. 2006). The four basic characteristics that need to be looked at for comparing devices are explained below. 1. Reliability Reliability ensures a procedure that is consistent, stable and dependable with minimal error on repeated measurement of the same variable (Pretty,…

In Intra-body communication the transmission medium used is human body, which has made much attention in personal area network(PAN).Since the signals pass through human body, the noise or the disturbances that interrups,obstructs,or the limits that effect the performance and interference is less to wireless technologies because the data is largely contained /transmitted with help of human skin. The characteristics of intra body communication are superior to those of other radio-based network…

advances in technology, have contributed to both a need and a means to create user friendly smart home devices. (Smart metering, 2015) Wireless sensor technology and handheld smart devices such as phones and tablets have become the platform on which this new wave of technology has been based. In combination…

In today’s world sensors especially optical sensors have many emerging applications beginning from the medical diagnostics to detect the pollution in the environment. Because of these wide range of applications the challenges faced to design, proper functioning and maintenance of an optical sensor requires immense knowledge of optical, material, and environmental properties that could affect sensor performance in all aspects. The wavelength range of the laser, interactions between the signal…

invented for monitoring health condition of an individual. This is fitted in the body of a person Wire Sensor Network or WSN is possible due improvement of sensor technology as well as computer miniaturization. As the data related to patients are stored in a WBAN it is imperative that security of the data must be maintained. Body Area Network is a system comprising of wireless network of sensors to monitor health designed for delivering personalized health-care. Acquiring communications inside…

account, then the sensors, Wi-Fi or GPRS, the location and finally the serial port. To minimize battery consumption, I did not use the GPS antenna to detect and acquire automatically the location. I manually added the location of the device in the codes using latitude and longitude coordinates. The Eco-Smart Can device will try to update the collected data to Internet on the Ubidots…

ECE-669c INDEPENDENT SUDY ON FIBER OPTIC SENSORS Mr. Prasanna M.Thawale School of Computer science and Engineering, California State University Northridge, Northridge-91324. Independent Study On Fiber Optic Sensors  Overview: Term: Fall-2014 Guide: Prof. Nagwa Bekir Topic: Fiber Optic Sensors .  Introduction: Fiber optic sensor since their emergence have been a sector of keen interest for researchers because of their specific and exclusive characteristics thus resulting into the…

(LCA) [5], [6], [7]: LCA, was one of the initial clustering algorithms evolved. It was primarily developed for wired sensors, but later applied in wireless sensor networks. In LCA, a unique ID number is allotted to each node and has two means of becoming a cluster head. The first way is that if the node has the greatest ID number in the set including all neighbor nodes and the node itself. The second way is to assume that none of its neighbors are cluster heads, then it becomes a cluster head.…

vehicles and other automobiles with vertically mounted rear window screens that are prone to dust accumulation. Modern automobiles are now being equipped with rain sensing wipers that detect the presence and quantity of rain by utilizing a rain sensor. This sensor automatically controls the speed of the wiper blades according to the amount of rain experienced. There is a variety of wiper blades in the market. The thing to keep in mind when shopping for a wiper blade is that it…
