A Smart TV adjusts the colour modes and contrast for every new frame. A Smart Air Conditioner adjusts the flow of air according to the room temperature. All these are nothing but miracles of technology. Every day we are witnessing tremendous growth in technology, which thereby affects all the aspects of our life. Nowadays, it is not just the mobile phones and digital cameras that come with latest technology, even washing machines have embraced newer techniques of washing.
The latest washing machines integrates state-of-the-art technologies, making the life of a home maker simpler and enjoyable. Washing clothes is no longer a gruelling job; it’s an experience in itself, with features like fuzzy logic, sixth sense, etc. The ‘Fuzzy Logic’ feature is making waves in the washing machine market.
What’s all this fuss about ‘Fuzzy Logic’?
The basic difference between a human being and a machine is that a human can think on its own whereas a machine cannot. This theory no longer holds good and ‘Fuzzy Logic’ is the proof. Fuzzy logic resembles human decision making with an ability to generate precise solutions from certain given information. It follows a set of fuzzy rules, just like the “if…….then” statement in a computer. For instance, ‘if’ the load is more ‘then’ set the water level to ‘high’.
Lotfi A. Zadeh, a professor of UC Berkeley in California observed that a conventional computer was unable to manipulate data representing vague human ideas. This paved the way to the discovery of ‘Fuzzy Logic’. It is a class of Mathematics that helps machines to reach a conclusion based on certain information. It uses the human approach to problem solving, with the only difference that it turns up with a decision much promptly than people do, and resolve problems that cannot be handled using conventional mathematics.
We learn through our experiences in life. Fuzzy logic can also be applied the same way. Japan is the leading country using this technology. They use this technology in everything – from cameras to industrial process control.
A powerful and effective technology
Washing Machines with fuzzy logic employ sensor technology to incessantly monitor varying conditions inside the machine, then accordingly adjust itself to ensure unsurpassed wash results using as little energy and water as possible. There is no universal pattern for fuzzy logic, hence different machines will do different things, but a common fuzzy logic will control the water intake, the main wash, water temperature, wash time, rinse performance and spin speed.
There are sophisticated machines that even weigh the load, advise you on how much detergent to be put in, assess material type and water hardness, and check if the detergent is a powder or a liquid. A few of them also learn from past experience, judiciously memorising programmes and adjusting them to minimise running costs.
Different manufactures might use different terms for this feature. Whatever be the term, Fuzzy Logic is here to give you the optimum cleaning performance using minimum water and energy. Quite a lot of machines with Fuzzy Logic earn ‘AA’ or ‘AAA’ grades for energy efficiency.
