Two domestic mechatronics systems
• Freezer
• Television
Types of freezer
• Regular freezer
• Deep freezer
Importance of freezer
• Deep freezer is just a term for a style of freezer, in that's it's generally dedicated as a freezer without a refrigerator section.
• It may also be called `deep' because the freezer box is usually deep so that it can hold quite a bit of product.
• Most deep freezers tend to have the opening in the top and can be a few feet wide and usually a bit longer, and around 2 1/2 to 3' deep. Of course, there's various makes and models from which to choose.
Identification process
• Regardless of what you are freezing or chilling, you will need refrigeration. And refrigeration is a purchased product.
• Refrigeration can be mechanically produced (in which case you are buying electrical power and transforming that power into refrigeration).
• First, this section has been created for the food processor that is looking for basic information about food freezing and cryogenics
• Alternatively, refrigeration can be purchased as a pre-cooled substance, such as liquid nitrogen (LN2) or liquid carbon dioxide (LCO2) and maintained in storage tanks. Freezing systems that use either of these refrigerants are generally referred to as being cryogenic* freezing systems
Working fields
• There are many reasons why processors freeze their food products.
• Increasing shelf life, stabilizing the product, lengthening lines of distribution and satisfying customer convenience are just a few reasons why the frozen sections of our supermarkets continue to expand.
• At CES we know that when choosing a method to freeze his product, the producer must consider the economics of freezing, the impact on his processing operations, and the expectations and concerns of his customers. We are here to help you evaluate the facts so that you can find the right solution.
Reliability
Product Market Life:
Food products, especially new entries into the marketplace, have varied degrees of success and market life. Sometimes a leased cryogenic system is a low-risk means of introducing a new product to the market place, and is then converted to a mechanical system once the capital can be justified by known sales volume.
Turn-Up Capacity:
Since processor needs can change so rapidly, a major consideration should be the ability of a freezing system to grow with a business

Television
Importance of television
• Tele visions playing an important role in our day to day life. It is really hard to imagine our life without TV, since most of us watch TV to get fun and entertainment.
• A lot of Television addicts are also available in this world and they are spending most of their times in watching TV.
• TV is the best way to get the recent news and information, as well as we have lot of entertainment shows in TV.
• News contains both positive and negative things, whatever it is, we gain a lot of information from TV.
Identification process
• Television or TV is a telecommunication medium used for transmitting sound with moving images in monochrome (black-and-white) or in colour, and in two or three dimensions.
• Progressive scanning (alternatively referred to as no interlaced scanning) is a way of displaying, storing, or transmitting moving images in which all the lines of each frame are drawn in sequence.
• This is in contrast to interlaced video used in traditional analog television systems where only the odd lines, then the even lines of each frame (each image called a video field) are drawn alternately, so that only half the number of actual image frames are used to produce video
• A plasma display panel (PDP) is a type of flat panel display common to large TV displays 30 inches (76 cm) or larger.
• They are called "plasma" displays because the technology utilizes small cells containing electrically charged ionized gases, or what are in essence chambers more commonly known as fluorescent lamp.
Woking fields
• In every homes
• Police control rooms
• Media stations
• Industries
• Schools
• Videogame centres
Reliability or satisfactory
• Our HDTV vendors received better-than-average marks on two of our four reliability measures
• Both LG and Panasonic won kudos for "any significant problems" and "overall satisfaction with reliability.
• Magnavox drew praise for its record on "problem on arrival" and "severe problem"; and Sharp distinguished itself on "any significant problem" and "severe problem."
• Relatively few manufacturers got tagged with worse-than-average grades on our reliability measures, but Mitsubishi ran the table with negatives–a sign that it needs to re-examine its quality assurance processes.
Task 2
Cnc machine
Computer numerical control
• CNC is the short form for Computer Numerical control. We have seen that the NC machine works as per the program of instructions fed into the controller unit of the machine.
• The CNC machine comprises of the mini computer or the microcomputer that acts as the controller unit of the machine. While, In the NC machine the programs fed into the punch cards, in CNC machines the program of instructions is fed directly into the computer via a small board similar to the traditional keyboard.
• In CNC machine the program is stored in the memory of the computer. The programmer can easily write the codes, and edit the programs as per the requirements.
• These programs can be used for different parts, and they don’t have to be repeated again and again.
• Compared to the NC machine, the CNC machine offers greater additional flexibility and computational capability. New systems can be incorporated into the CNC controller simply by reprogramming the unit. Because, of its capacity and the flexibility the CNC machines are called as “soft-wired" NC
Specific operational
• The cnc machine is reduce the work of the labours
• Production rate of the industries will be high
• The work will be accurate and perfect
• Time consumption will be reduce
Development of cnc machine
• The first cnc machine was built in the 1950, based on existing tools that were modified with motors that moved the controls to follow points fed into the system on punched tape.
• These early servomechanisms were rapidly augmented with analogue and digital computers, creating the modern CNC machine tools that have revolutionized the machining processes.
• After 1960 American companies was developed the cnc machines
• In 1975 the Japanese companies are involved to develop and manufactures the cnc machine lower cost comparing to American companies
• Germen companies also involved to manufacture and use the cnc machines for the production
• Now days, cnc machines are mostly useful for all the industries. Because It was useful to increase the production rate of the company
• And it will reduce the labour cost
