Embedded Computers in Household Appliances


An embedded computer is a single chip that contains all of the elements that are essential for any computer such as RAM, ROM, CPU, Input, Output and Clock. Another term often used for an embedded computer is a 'micro controller'. This is because the main purpose of an embedded computer is to control something. A lot of things have an embedded computer in it such as
Plasma television.









A Plasma televisdion is a high definition (HDTV) alternative to the standard cathode ray televisions sold today. A plasma television provides sharp images and vibrant colors, especially when used in conjunction with high definition broadcasts. Quite often a plasma TV is designed in a 16:9 ratio for wide screen movie formats, as opposed to the box-like 4:3 ratio of standard televisions. A plasma television such as Philips and Sony are not cheap, however. Units start at $1,000 BND and can be as high as $15,000 BND or more.
The very first prototype for a plasma display monitor was invented in July 1964 at the University of Illinois by professors Donald Bitzer and Gene Slottow, and then graduate student Robert Willson. However, it was not until after the advent of digital and other technologies that successful plasma televisions became possible.

Effects that robots have brought to the Working Enviorment

A robot is a virtual or mechanical artificial agent. In practice, it is usually an electo-mechanical system which, by its appearance or movements, conveys a sense that it has intent or agency of its own. Robot also have a lot of advantages, but that doesn't mean robot have no disadvantages here are some of them:
The Advantages of Industrial Robots
1.Quality:
Robots have the capacity to dramatically improve product quality. Applications are performed with precision and high repeatability every time. This level of consistency can be hard to achieve any other way.
2.Production:
With robots, throughput speeds increase, which directly impacts production. Because robots have the ability to work at a constant speed without pausing for breaks, sleep, vacations, they have the potential to produce more than a human worker.
3.Safety:
Robots increase workplace safety. Workers are moved to supervisory roles, so they no longer have to perform dangerous applications in hazardous settings.
4.Savings:
Greater worker safety leads to financial savings. There are fewer healthcare and insurance concerns for employers. Robots also offer untiring performance which saves valuable time. Their movements are always exact, so less material is wasted.
The Disadvantages of Industrial Robots:
1.Expense:
The initial investment of robots is significant, especially when business owners are limiting their purchases to new robotic equipment. The cost of automation should be calculated in light of a business' greater financial budget. Regular maintenance needs can have a financial toll as well.
2.ROI:
Incorporating industrial robots does not guarantee results. Without planning, companies can have difficulty achieving their goals.
3.Expertise:
Employees will require training in programming and interacting with the new robotic equipment. This normally takestime and financial output.
4.Safety:
Robots may protect workers from some hazards, but in the meantime, their very presence can create other safety problems. These new dangers must be taken into consideration.
