Just In Time : Todays Requirement

Guys, I might think that all you come across the words like QMS, TPM, EMS, FIFO, OHSAS, KAIZEN and KANBAN, etc. We are dealing with such systems while working with an organization. Each system has it's unique identity and only one effectiveness pertaining to the Quality and Productivity.

Here I am going to furnish one more unique system known as JIT (Just In Time).

Just-in-time, opened up by Taiichi Ohno in Japan at Toyota car assembly plant in the early 1970s, is a manufacturing organization philosophy. JIT cuts waste by supplying parts only when the assembly process requires them. At the heart of JIT lies the KANBAN, the Japanese word for card. This KANBAN card is sent to the warehouse to recorder a standard quantity of parts as and when they have been used up in the assembly/manufacturing process. JIT requires precision, as the right parts must arrive “just-in-time” at the right position (work station at the assembly line). It is used primarily for high-volume repetitive flow manufacturing processes.

Historically, the JIT philosophy bobbed up of two other things:

1. Japan’s wish to improve the quality of its production. At that time, Japanese companies had a bad reputation as far as quality of manufacturing and car manufacturing in particular was concerned.

2. Kaizen, also a Japanese method of continuous improvement.

The Just-in-time framework regards inventories as a poor excuse for bad planning, inflexibility, wrong machinery, quality problems, etc. The target of JIT is to speed up customer response while minimizing inventories at the same time. Inventories help to response quickly to changing customer demands, but in such a manner as could not be otherwise cost money and increase the needed working capital.

Typical attention areas of JIT implementations include:

1. Inventory reduction
2. Smaller production lots and batch sizes
3. Quality control
4. Complexity reduction an transparency
5. Flat organization structure and delegation
6. Waste minimization

Through the arrival of Internet and Supply Chain Planning software, companies have in the mean time extended Just-in-time manufacturing externally, by demanding from their suppliers to deliver inventory to the factory only when it’s needed for assembly, making JIT manufacturing, ordering an delivery processes ever speedier, more flexible and more efficient. In this way Integrated Supply Networks (Demand Networks) or Electronic Supply Chains are being formed. Just-in-time is sometimes referred to as ‘Lean Production’.

So, anywhere you are working with an organizations, if you come across the JIT system, please work upon the philosophy based on "Just In Time".

How to prevent your PEN drive from VIRUS

Guys, viruses are true enemies of our systems. Doesn't matter it may be the human (you have to just think over it). Many of your PC/laptop's normally gets virus because of Pen Drives or USB devices (even PC's who are not connected to network). Some Virus like Ravmon Virus , Heap41a worm which are not detected by anti virus normally spreads mostly by the Pen Drives . In such a case what can you do to prevent your PC from getting infected with Virus that spreads through USB devices or Pen Drives?

You can protect your PC by just following the simple steps below . It won't take much time.

1. Connect your Pen Drive or USB drive to your computer.

2. Now a interlocutory window will pop up and asking you to choose among the options as shown in the figure. Don't choose any of them, Just simply click Cancel.

Remember the following when using your mobile phone

Dear guys, please consider the following tips when using your mobile phone.

It is not only the choice of phone, but how you use it that is important when you want to control the amount of radiation you are exposed to. Here. You will find a few simple tips that can considerably reduce radiation and therefore also health risks.

Use a handsfree set.

The further away from your body the phone is, the less radiation you are exposed to. Using a hands-free set is the easiest way to radically reduce the amount of radiation you are exposed to if you use a mobile phone.

Hold it at the bottom.

By covering large areas of the phone with your hand, you reduce its ability to send and receive signals. The phone then increases its power and transmits stronger radiation to compensate this. So hold the phone as far down as possible, so it can operate at low power.

Get in the Best Position.

You can see the signal reception strength in the display. When reception is good, the phone reduces power and radiation. If reception is poor, the phone uses maximum power and radiation.

Use a regular phone if possible.

If you have a regular phone, then make calls with it. The amount of radiation is directly connected to the length of time you talk on the mobile phone.

Don't talk too long.

The radiation you are exposed to is directly related to the time you spend talking on your phone. For longer calls it is safer (and cheaper) to call from a regular phone.

Hazardous areas of use.

Do not use a mobile phone when driving a car. Stop at a safe place and talk.
Do not use your mobile phone in places where there is a lot of electrical equipment, such as hospitals and aircraft.
Do not bathe with your mobile phone.
Do not let small children talk on your mobile phone for long periods. They are more susceptible than adults.

Mobile Phone Ethics.

Show consideration to those around you when you have your phone with you.
Your colleagues may not be as keen on your phone as you are.
Turn off your phone when you are in public places such as movie theatres and cafe.
Make a habit of turning it off? it is good for you too.

Remember the following when using your mobile phone.

A mobile phone can be of great use when you really need it. Just remember:
Use a hands-free set
Hold it at the bottom
Get in the best position
Use a regular phone if possible
Don’t talk too long
Mobile phones are not suitable for use everywhere
Show consideration to those around you.
The lighter side of ‘Mobile mayhem’ follows...

A software helps to restore speech in a paralysed man

Guys, it is a new software who have helped to restore speech in a paralyzed man. This new software decodes the signals from a neural implant and voices them through a synthesiser.

Guys, it is a group of US-based scientists have provided a paralysed American man a chance to speak again, thanks to an electrode implanted in his stroke stricken brain.

Erik Ramsey, 24, was left 'almost totally paralysed' when he suffered a brain-stem stroke after a car accident years ago, however his mental faculties remained intact. In 2004, Phillip Kennedy's team at Neural Signals - a bioresearch firm based in Georgia, USA - implanted an electrode in his speech-motor cortex, hoping that the signal from Ramsey's cortex could help in restoring his speech. But this proved to be easier said than done.

However, another team led by Frank Guenther at Boston University was working on a similar problem at the time. Studying brain scans of healthy patients showed that brain signals don't code for words, but instead control the position of the lips, tongue, jaw and larynx to produce basic sounds.

Guenther's team then developed software that could identify and translate the patterns of brain activity during speech.

However, Klaus-Robert Muller at the Technical University of Berlin believes the technique might not be apt for fully 'locked-in' patients, who can't control any muscles. If you have completely locked-in patient, then the brain may begin to degrade because they are not able to control anything. Those patient might be completely unable to brain-control interface.

Guys, it is the development of Dr. Philip Kennedy and colleagues. The Doctors team developed a software that translates thoughts to a synthesiser via a neural implant, helping disabled patients communicate. What an Idea?
