Car Safety Features.

About 8 million cars are made in India every year and the market is growing like never before, the increased buying of cars has led to increased road traffic and road accidents too. India has a nasty distinction of having highest (in number) road accidents leading to over 130,000 deaths a year. While there are several factors for the road accidents, it is good to have a car that has security features loaded. Modern day cars as in these days come stuffed with safety and standard comforting features, thanks to the growth of the car industry over the years. If you are going to install safety features on your car then certain measures like bonding to an insurance company can offer you some benefits and discounts, for these features add to safety of the car, your eventual premium might come down or you have a chance to avail of a waiver as a bonus and thereof. In reality it is the role played by the insurance companies to up the security features in the cars. Some of the latest safety features available for the latest car models are:- airbags, active head resistance, car safety belts, anti lock brake system(ABS), tyre pressure monitor system, built in or child safety seats for children. All of them are very useful for the safety. The air bags are one of the important safety features. It has undoubtedly become a must-have security feature for the cars. Designed for critical

Electronic Combination Lock - create a secure lock to protect a property from intruders.

Electronics Coursework Electronic Combination Lock Aim: * The aim of this project is too create a secure lock to protect a property from intruders. To do this I have researched how to construct an electronic combination lock. During this project I will create a lock that is a great deal more secure than a standard mechanical lock, the reasoning behind this is that an experienced locksmith can open a mechanical lock without any trouble. On the other hand an electronic lock will seem a lot more of an obstacle to open as you have to input 4 switches in the correct order to open the lock successfully increasing the security highly. Research: * I have researched some factory made electronic locks to compare with the design that I will make. Of course my project will be much simpler than some of the combination locks that I have found on the Internet. (http://www.quasarelectronics.com/3029.htm). * One of the factors of the circuits that I need to consider is what the input would be (for example a keypad or simply switches.) I have decided that a keypad as an input is too complicated to build effectively and fault finding will be very difficult, because of this I will include 4 switches as the input to make the circuit simpler and easier to build, and fault find if there are any problems after construction. * The second factor that I will consider is the amount of active

Solar Power

Since the U.S. is at war in the Middle East to protect its foreign oil interests, we have seen a rapid fluctuation in oil prices, first 35$, and 70$, and in recent days 115$` (Matthew Knight, CNN). As China, India and other nations rapidly increase their demand for fossil fuels; future fighting over energy looms large. In the meantime, power plants that burn coal, oil and natural gas, as well as vehicles everywhere, continue to pour millions of tons of greenhouse gases into the atmosphere annually, threatening the planet. Scientists, engineers, economists and politicians have proposed various steps that could slightly reduce fossil-fuel use and emissions. These steps are not enough. The U.S. needs a system to free itself from fossil fuels. My analysis is that a massive switch to solar power is the logical answer. Solar energy's potential is off the chart. The energy in sunlight striking the earth for 40 minutes is equivalent to global energy consumption for a year. (Solar Southwest), and this shows the practicality of solar energy, but there are many other steps needed to successfully achieve this goal. If we are to convert the country to solar power, massive amounts of land would have to be covered with photovoltaic panels and solar heating troughs. A direct-current transmission backbone would also have to be constructed to send that energy efficiently across the nation. The

Building a Computer Based Measurement System

BUILDING A COMPUTER BASED LABORTARY MEASUREMENT SYSTEM Introduction: Electric systems are made up of three main parts: input, processor and output. The input is the part that would convert the input signal to a voltage, so therefore changes the form which information is presented in. the electrical signal is then passed into the processing block, which process the input information, however the signal coming out of the processing block is still an electrical signal but it has been changed, which point to it being processed. The last part of an electric system the output responds to the processed electrical signal and changes it in the form of light, heat, sound. In electric systems the input and output use devices which convert signals from one form to another. Theses are called transducers. Transducers can be divided into input transducers and output transducers. Input transducers are devices convert physical quantity such as light and temperature levels into a voltage or some other electrical quantity. A light independent resistor is responds to changes in light intensity by changing its resistance. The change in a resistance can be used in a simple circuit to produce a changing voltage. Output transducers change electronic signal back to some form of physical quantity e.g. loud speakers converts an electronic system into changes in air pressure producing sound. Electronic

Developing a Fridge Add-On

Research To help me with my design I need to find out information about - 555 timer- what does it do? What is it made from? What do the pins do? How will it go in my circuit? LDR What does it do? How does it work? How is it powered? "Anyone who uses a refrigerator will be able to use this product. This product is something useful which anybody can benefit from it is a product that can be of assistance to you in everyday life." It will be used in the kitchen inside a refrigerator so the circuitry will have to be concealed within a casing. This is because the refrigerator operates below room temperature and therefore the circuitry must be able to operate under these conditions. The casing is a vital part of the product because in a refrigerator many things can easily damage the circuitry. To operate this product there must be a power supply and the only thing, which could be used and concealed completely, is a battery. The battery though must be easily accessible for maintenance purposes. The best material to construct the casing from would definitely be some type of plastic and this has to be waterproof and easy to clean. The plastic would have to blend in with the interior, not making its presence too obvious. I would say that this specific product should not be too expensive to produce and easily applied. The product is odourless and silent when not in use

Electronics in Society

Electronics in Society Electronics has had a great impact on modern society. Throughout this essay i shall be studying the general development of electronics in modern society. I shall begin by describing some of the different areas of society which have been affected by electronics. Areas of Society that have been Affected by Electronics The home entertainment industry has had a massive impact over the recent years as many new forms of entertainment have been introduced, For example Digital versatile Discs (DVD) and Mini Disks have only recently entered the home. The effects that electronics has had on this industry have been somewhat entirely positive, as without electronics the entire industry would cease to exist. All current media forms are electronic, ranging from the video cassette player, the portable CD player or the home DVD player. These devices have made huge impacts on modern society, as for social aspects more and more people stay in to enjoy these forms of entertainment each year, however this is ultimately leading to a more unfit society and overweight future generations. However the ability to enjoy a cinema-like atmosphere in your own home with technologies such as 'Dolby Surround Sound' widescreen televisions and crystal clear picture quality is highly convenient and enjoyable as a whole. In the manufacturing industry electronics has made a massive

"Morning General could you knock next time." "Sorry Sir." "At ease! How may I help?" "Thank you sir. I just heard someone shouting I thought there was a problem" "No, no problem, you should know by now that we shout in the army. You may leave." "Thank you sir!" "Now Melvin nothing will happen, it will be ok. Don't worry." "Sorry sergeant I just get nervous. You know how it is" "How many times! Call me Tony." "Sorry." "You can go now, remember tell no-one." "Y-y-y-es s-sir." "For heavens sake stop shaking man!" Melvin goes home and gathers the things that he needs. Tony is talking to a good friend on the phone. "Hi Joe. I was thinking of installing some security round here. A few things have been going missing and I was wondering what kind of security they have over there because it looks like it's not very heavily guarded." "That's what they want people to think, but its got all these hi-tech gizmos." "Really! Like what?" "Well I can't tell you, it's against the rules." "Come on, I have been your friend for 10 years now." "True. Well they only have two security systems." "Only two?" "Wait for it. They have a battery sensor."

Page 1 - Target Market for my nightlight.

The target market is for both children and parents/guardians of the child. The child’s automatic night light will be made for the use of little children (of both genders) aged between 2-5 years olds, which therefore must appeal to them and be a product which is both enjoyable for them and safe. However, the night light must also attract the attention of parents/guardians, as they will be buying the product, and so costs must also be moderately low as the product will be aimed and brought by middle-class citizens, earning around £25,000 in a household yearly and so they will have disposable income and will be able to spend £5-£10 on a night light for their child. These parents/guardians will be working either full-time or part-time and will also be family orientated. The child’s night will also be portable and so the parents may enjoy going on holiday with the children. The child’s night light will be used whenever light is needed to brighten up a dark area, this is likely to be during night-time before a child is going to sleep or when a child wakes up during the middle of the night needing to go to the toilet. Therefore, the product, will be beneficial for night time trips to the bathroom as there will be no need for the child to fumble around for the light switch and no longer will the child feel scared to go to the bathroom in the middle of the night. The night

Finding the Spring Constant of a Copper Spring Using a Potential Divider

Finding the Spring Constant of a Copper Spring Using a Potential Divider .0 Aim To undertake an experiment to assess the behaviour of a potential divider as a sensor. 2.0 Objectives * Build and test a sensor. * Explore the characteristics of the sensor. * Calibrate the sensor. 3.0 Introduction The system, which I am using to find the constant of a spring, could be used for quality control in industries where springs are made. Potential dividers are used in strain gauges in buildings to calibrate subsides. The potential divider in the circuit is going to be used as a position sensor. A potential divider is simply two resistors, across which a voltage is applied, with the output being taken from the junction of the resistors. If a single variable resistor is used for R1 and R2, then the output voltage can be varied, and this is the basis of the volume control. 4.0 Method A potential divider will be placed in the middle of a 25cm long ruler at 12.5cm. A hole needs to be drilled through the centre on the ruler at 12.5cm to attach and hold the potential divider. To the left-hand side of the ruler a small hole will be used to thread some wire through to produce a pivot. At the opposite end of the ruler two holes will be drilled. The hole at the top right will be drilled to hook the spring onto, then at the bottom right to attach the weights to. Two clamp stands will hold

Build a sensor that detects air flow using an incandescent lamp to detect the air flow.

Aim: The aim this project is to build a sensor that detects air flow using an incandescent lamp to detect the air flow. An LED will also be included in the circuit and as the air flow increase the brightness of this LED will also increase. A voltmeter will be connected in parallel to the Led to detect the changes in voltage as the airflow changes. Introduction: The circuit will use an incandescent lamp to detect the airflow. The glass around the bulb will have to be cracked, this will expose the filament. The glass will be cracked by wrapping it round in masking tape and cracking, therefore the glass can be removed without damaging the filament. With the filament exposed to the air, a constant current source is used to slightly heat the filament. As it is heated, the resistance increases. As the air flows over the filament it is cooled down and therefore lowering the resistance. An LED which is connected in the circuit detects these changes, as the resistance decreases the LED gets brighter. A voltmeter is connected in Parallel to measure the changes in voltage giving us estimation on the airflow. There will also be a potentiometer connected to the circuit; this will allow you to vary the sensitivity to resistance of the LED. Plan: The circuit will be supplied with 12volts. I will be using a board were you have to push the components into the holes, this will
