Bluetooth technology: What are the issues?
Title Bluetooth technology: What are the issues? Done By Sharif El-Sharif A. Presentation of the Issue When you use computers, entertainment systems or telephones, the various pieces and parts of the systems make up a community of electronic devices. These devices communicate with each other using a variety of wires, cables, radio signals and infrared light beams, and an even greater variety of connectors, plugs and protocols. Bluetooth technology offers a completely different way to form the connections. Bluetooth is wireless and automatic, and has a number of interesting features that can simplify our daily lives. Bluetooth wireless technology revolutionizes the personal connectivity market by providing freedom from wired connections - enabling links between mobile computers, mobile phones, portable handheld devices, and connectivity to the Internet. B. The IT Background of the Issue Bluetooth conceived initially by Ericsson, before being adopted by a myriad of other companies, Bluetooth is a standard for a small, cheap radio chip to be plugged into computers, printers, mobile phones, etc. A Bluetooth chip is designed to replace cables by taking the information normally carried by the cable, and transmitting it at a special frequency to a receiver Bluetooth chip, which will then give the information received to the computer, phone, whatever. Bluetooth
Future Technologies
Special Topic: Future technologies Prognoses of the future technical development Nobody really can say in which direction our science goes. There are so many different subjects that can revolutionise the whole world. Here are some examples of these future technologies: Gene engineering: The scientists think that they will have completely decoded the DNA (Desoxy Ribo Nuclein Acid) of humans in 50 years. After that we will be able to create a human with all the attitudes we want to give him. (more intelligent or good looking, for example). Today we are able to clone an organism and force bacteria to produce medicine. It sounds simply you just put the gene (building plan) for the enzyme (medicine) into the DNA of a bacterium and you let this bacterium multiply itself. After a certain time you have millions of bacterias which produce the medicine you want. Fusion energy: This technology can change society completely. We would have unlimited energy for the whole world. The sun is the best example. It has been burning for billions of years just with the help of fusion energy. With further researches perhaps it will be possible to replicate any atomic element, connection, molecule and material we want. Robots: Today many people could not imagine working without their computer. This computer technology is the base of Robots, Computers that can walk and talk. Today we
Ultrasounds and why they are helpful to humans
EXTENDED ESSAY Ultrasounds and why they are helpful to humans Ivan La Bruna D #0261-011 American School of Milan IB Extended Essay May 2003 Word Count: 3770 Abstract Ultrasounds are sound waves that exceed the limit of human hearing. In latin ultrasound means that it goes beyond a boundary, in this case the sound wave goes over our hearing capacities. The study of sound waves could be considered ancient study because sound was always an interest of the people. This is why people created many musical instruments in different areas, the most curious thing is that the shapes differ from location and also produce different sounds. Without these studies on sound scientists or explorers probably would have not reached the level of wave reproduction there is in modern times. In the past sound waves were reproduced with wind and string instruments while in modern days scientists are able to create a sound wave with specific requirements. What will be discussed in this essay will be an explanation on what aer ultrasounds and why they are applied to society. Ultrasounds are used mainly in the medical environment but also in detecting the distance of objects, on submarines, and other uses which will be discussed. The good thing about ultrasounds is that they are not very expensive and for this reason it has expanded more and more. For example ultrasounds are used in the
The changes being brought by computers have fundamentally changed the shape of working life. The biggest problem is that it has created an underclass that has fallen out of the bottom of the job market.
Before the industrial revolution nearly everyone worked in agriculture. Communication was by word of mouth or paper. When the industrial revolution came, life became more complicated. People started to work in factories and the factories needed offices to deal with administration. The amount of paperwork needed to trade started to increase. As time went on, technology was used to develop machines such as the typewriter and telephone and eventually, the computer. We are now in an 'information age' and our society is very dependant on information storage and communication. What is the effect of new technology and the consequences of it on the work organisation is the topic that I will dicuss. New technologies will make it easier for companies to manage and out source services. Hollywood is a prime example where a team of individuals, firms and skills is assembled to make every film. Out sourcing is not necessarily the correct approach or solution but it becomes easier to manage with new technologies. While work can be decentralised a reverse effect of new technology is to increase the power of the centre Technological change can also change corporate culture. For many people work is a place to go and a place to enjoy a significant part of their social life. The future will see work as something to be done independently of location. This can lead to the curse of accessibility,
Robots.- the concept of a robot this project is concerned with, the history of robots in industry, a more detailed study on the robots market and the nations that use them, the current status of the industry, and possible future trends.
Robots. Robots are needed in industry. They bring many benefits to workers as well as company owners by taking care of difficult and dangerous jobs and by being cost effective. They constitute another tool in manufacturing sites that contain, for example, advanced assembly lines. The concept of a robot goes back as far as the Egyptians time. Early ideas about the use of robots presented problems in terms of their functions to society and the way in which they affected the opportunities of skilled workers. However, robots managed to stay in industry for good. Presently, single purpose systems, like welding or palletizing robots, are dominating the market. At the beginning of 1998, analysts estimated the robotics industry at $8 billion worldwide. Further developments in the robotics field will be driven by the development in related industries such as the industry of sensors and the industry of chips. Future customers will probably ask for robots with more autonomous capabilities. This idea is driving robot-manufacturing companies to consider new developmental areas in the field of robotics. In general, the sections below will basically explore, in order, the concept of a robot this project is concerned with, the history of robots in industry, a more detailed study on the robots market and the nations that use them, the current status of the industry, and possible future
HEALTH AND SAFETY
HEALTH AND SAFETY The Health and Safety at Work Act 1974 "brought together a range of legislation covering health and safety since the first act was introduced in 1802" (Moonie et al, 1994:232). Although the act emphasises the responsibility of the employer on health and safety care workers must also have an awareness and understanding of their health and safety responsibilities in relation to relevant legislation such as * The Health and Safety at Work Act, 1974 * The Management of Health and Safety at Work Regulations, 1999 * Control of Substances Hazardous to Health Regulations (COSHH), 2002 * Reporting of Injuries, Diseases and Dangerous Occurrences * Manual Handling Regulations, 1992 (amended 2002) * Health and Safety First Aid Regulations, 1981 Important ethical issues arise with the exercise of the above duties through the Codes of Practice and the Human Rights Act 1998. The Codes of Practice help classify the quality of care clients can expect if they receive care services and they can be used as a source for measuring the quality of care provided. Issues arise because they involve questions of the restriction of liberty and adjudication by health and social care workers, between the sometimes competing interests and wishes of individuals and their families and communities. The Health and Safety at Work Act, 1974 is comprehensive and recognises that
How do graphic designers give images meaning and how is symbolism achieved?
Graphics How do graphic designers give images meaning and how is symbolism achieved? In this piece of work I shall be talking about how graphic designers give images meaning and how they achieve symbolism. I am aiming to find out what is the definition of 'meaning' and 'symbolism' and find how graphic designers achieve these. My plan in this essay is to define 'meaning' and 'symbolism', with questions like, "What is the definition of meaning?" and "What does symbolism mean?" Afterwards I shall proceed to then use 3 pieces of work from chosen graphic designers that show these subjects and explain how they express them. Firstly, before I go in depth about certain pieces of work, I think it is important to know the definitions of 'meaning' and 'symbolism'. The word meaning is defined as "Something that is conveyed or signified; sense or significance" In terms of graphic design, the designers produce a piece work to show a meaning to their style of work. The word symbolism is defined as "Symbolism is the applied use of symbols and it is a representation that carries a particular meaning". For this piece of work I shall be looking at 3 designers and their work and shall be going to into great analysis. This analysis will include questions like, "who is its target audience?" and "what is the purpose of the image?" I find that a main source of meaning and symbolism in graphic
Design of a flash light. Even though this device is so simple but in this design there are four major problems:
A Poor Design: Flashlight A flashlight consists of a battery, a switch, and a lamp. Simply the switch (user control) and the battery are the inputs of this system and the light, and some heat, are the outputs. This circuit is then placed inside a case and a reflector is mounted at the back of the lamp to direct the light into the object. Figure1: Flash light shown from 4 different angles. The cubic shape of the flashlight makes it uncomfortable to carry. . The Problem: Even though this device is so simple but in this design there are four major problems: * Cubic shape of the flashlight * Poor choice of On/Off switch * Flat Reflecting mirror * Non-rechargeable and non-standard battery Shape: Maybe the most important characteristic that every flashlight must have is to be comfortable in hand. Most Flashlights are in the shape of a cylinder such that fingers can wrap around it easily. In this design however, the cubic shape of it makes it hard to hold in hand. Also, the head of the flashlight where the light is located is angled upward without any logical reason, whereas it would have been better if the light was pointing downward. Switch: The part that causes the most frustration in this design is the on/off switch. Unfortunately the switch doesn't stay on and your thumb must maintain constant pressure on the switch to hold it up; otherwise it will turn off. After a
Devlopment evaluation of my bedside table.
Development Evaluation Product Design Specification Criteria My Evaluative Comments My Client's Evaluative Comments PURPOSE: The purpose of the bedside table is allow somewhere for essential items to be stored and accessed at ease i.e. medicines, tablets etc. Also somewhere to store regular house hold items i.e. telephones, perfume bottles, books etc The chosen design accommodates somewhere for essential house holds items to be stored and accessed at ease because of the lightweight design and other features such as the pulling drawers make it easy to access items also the lightweight design would make the product relatively easy to move around the room. Product appears that essential items can be stored and accessed at ease FUNCTION & PERFORMANCE: > Suitable for the use of people aged 55 and over, as this is the target market I am designing for. > The height of the bedside table should be 635mm as this half way between the two most popular ranges I found from my research, a further 80mm should be added on to this height as is height of a standard bed plus the thickness of one standard pillow, so items do not get knocked off when arms are stretched out in bed, so the overall height of bedside table should be 715mm. > The width of table from side to side should be 500mm as this is approximately the correct range of space my target market would have left on
Food is a concern to both manufactures and consumers. Explain how a food manufacturer and local authorities can ensure that food poisoning risks are reduced.
Food is a concern to both manufactures and consumers. Explain how a food manufacturer and local authorities can ensure that food poisoning risks are reduced. The term food poisoning actually means disease resulting from ingestion of food contaminated with a toxin produced by a micro organism. The most common types of food according to nhsdirect.com are Campylobacter, E.Coli and salmonella. These are caught from foods such as contaminated water, raw chicken, milk and eggs. According to the Food Standards Agency, it is estimated that up to 5.5 million people in the UK are affected from food poisoning each year. There are many possible ways of preventing this on both the consumers and the manufacturer's part. It is more the manufacturer's responsibility to ensure that their food that is being produced does not become contaminated. One of the most important factors a manufacturer can do to prevent food poisoning is to train their staff properly. It is important that the staff are capable of cleaning thoroughly the equipment used throughout the production of the food. A basic food hygiene certificate is now expected when handling food. It would also be a good idea for the manufacturer to employ supervisors to ensure that the other staff are doing the correct jobs in the correct ways. They can also ensure that the equipment is being used and working in an appropriate way.
