Movie watching is one of the best ways to get ourselves entertained. It is cheap and is a good pass time. In 1950’s people use to watch movies in a movie theater which was backward. The ventilation was not proper, the chairs were uncomfortable, the sound effects were horrible, the picture quality was poor and It was a black & white cinema with a stereo type content.However, with the introduction of a colored TV and a VCR (Video Cassette Recorder) the experience of watching a movie has got improved. With these 2 devices people could sit back home and enjoy their favorite movie with their families, friends, relatives etc.

Role of Instrumentation in Industry.
Instrument plays a big role in industry. Now almost in every industries automation system introduced. So during running time of plant we have to set some control in input and output and also during processing. These all are done in auto now a days.
So we have to measure some parameters like level, pressure, flow and temperature.
While automation system is running we look all these parameters carefully so that production are not hampered, otherwise we may face to a big lproblem or loss.
Temparature-
First we can discuss about temparature measurement. In various industries various temperature measurements needed. In small industry low temperature measured and in heavy industry high temperature measured like in steel plant. For low temperature we use RTD (Resistance temperature detectors). It may be two or three probe system. The difference between two wires (one positive and one negative) creates some Voltage and through a transmitter we can convert it to a digital reading.
Pressure-
Pressure is an important part of any industry. We all know that high pressure can make a explosion and in low pressure system will not work properly. So we have to measure pressure to look and control. Generally two tapping points are used to measure with two impulse lines. One is connected with the line on which we want to measure and other is opened to air. Thus a differential created and through transmitter we can measure it. Here transmitter works as a converter from differential to voltage or current.We may use some pressure gauge but all are pneumetic.
Flow-
Transmitter-
Flow is also important to measure. How much volume or quantity is needed, the flow measurement detects it. In industry water is needed, gas, raw materials are also needed. So we have to measure flow. here also a transmitter is used like pressure measurement. But the difference is two impulse lines are connected with directly to the line. An orifice or ventury system is used to create a differential. The amount of differential will vary and we can measure the flow with the help of Transmitter.
Level-
Level is also an important part which indicates the stock and water level in tank etc.
If we count the stock in number then no problem but how can we say that how much stock is needed to continue the production automatically. So level measurement is also important. This measurement is quite tough though different methods are applied to measure. Normally two lines are tapped and we may say one as low line is connected in the lower part and high line is connected with open place. Thus a differential is created and the measurement is taken.
One more thing is important that is calibration and maintenance .We need some reference to measure any thing. So we have to calibrate all instruments and put some range in it.
Smartphones are very useful these days and with it one can do his/her work on the move. Browsing, Office apps, image/video editing, games and tons of other options bridges the gap between a computer and a cell phone. But the villain is the battery life. Users often gets their batteries drained within hours. With some precautions and setting one can increase the battery life. Some of the most important things are listed below.
Avoid Wallpaper and Screen and huge themes
It’s true that many of us give great importance to wallpapers. Some even browse the web hours to find a cool wallpaper to impress others. But the fact is that this doesn’t impress the battery! It’s better to avoid wallpapers and screen savers. Even if you are using a wallpaper make sure the size of the file is not huge. Also go for simple themes - may be the default one. All these factors will increase the performance of your phone. With Android there are live wallpapers and other such stuff which are very cool but they may eat your battery fast.
Turn off the Wi-Fi & Bluetooth & 3G
Well, some people doesn’t bother to turn off their Wi-Fi and bluetooth after using them. So the phone will be searching for networks and devices all the time, even when the user don’t want them. This will cost you a great deal of battery life. So you’d better turn’em off. It is also not secure to let other devices and networks find your device. Though 3G helps you to browse the web much faster, it is not a good option for your battery. It’s better you rely on other simpler internet options rather than 3G when you’re away from the charger.
Close the applications after using them
Most people, knowingly or unknowingly, open applications and return to th Home screen without closing the application. So there may be dozens of apps running on the background. I your iPhone, just double tap the home button and a list of active apps will pop up touch and hold the icons of these apps until you see a close icon on them and close the ones you are not using. Running too many apps at the same time will increase the work load of your device and it may affect your battery life.
Turn off special features like motion sensor, gravitation sensor, touch vibrate etc.
Turn off the above mentioned features. Features like auto rotate might be cool but it also consumes more charge. Some cell phones have a feature which vibrates the phones when we uses the touch screen. All these thing affects the battery life.
Use Flight mode on the move and avoid Vibration mode
When you’re on the move your network coverage may come and go in times. Your phone, as it moves, leaves from one tower for network coverage to another. These processes will drain a lot of battery charge within less time. So it’s better to turn your phone to Flight mode when you travel and turn off the flight mode whenever necessary. Also, the vibration profile will use considerably more battery charge, it’s better to avoid them.
Turn off keypad tones, decrease the screen brightness etc.
There are so many other simple options one can do to lower the battery consumption. You can turn off key tones, lower the screen brightness, dim the screen faster when phone is not in use, decrease the ring volume etc. to increase the battery life.
Apps to protect and increase your battery’s performance.
In Android and iOS, there many useful applications which are designed for the effective use of battery. They’ll manage the processes in favor to the battery. So try such apps.
Only install the apps you need
Some people have a habit of installing loads and loads of apps. They won’t even use these apps but they keep on adding new apps and they don’t remove the apps they don’t use. The best thing to do is to install only the apps you want and avoid the rest.
Take extra batteries, backup chargers etc. while you travel
The best way to avoid battery issues while traveling is to take one or two extra, fully charged, batteries. Also there are so many backup chargers, solar chargers etc. are available in the market. Purchase some of them, be sure to purchase such accessories from reliable brands otherwise it may harm your battery in the long run.
Keep these thing in mind when you are about to start a journey. And it will surely bring you a - Happy Journey!
The history of bowling dates back thousands of years. It is believed by many that a passion for hitting a bowling pin with an object actually struck humanity sometime in the Stone Age. This passion has never gone away, as evidenced by the worldwide popularity of the sport.
As man evolved, so too did the game and its trademark bowling pin design. Whereas the first pins likely were made of stone or another crude material, the pins of today have come a long way. Modern pins are precise creations typically made of wood. Each one is uniform in design specification down to the thickness of the necks and the height they stand.
The history of bowling marched forward from the Stone Age into actual royal courts. The first mention of the game in written history involves English King Edward III who, in 1366, actually banned the game to force his soldiers to focus more on their archery practice. From Edward's court, the game moved on to the time of King Henry VIII. It was in Henry's time the game became one enjoyed greatly by nobility.
In Colonial America, the game made an appearance and was often associated with gambling. The bowling pin count in this earlier form of the game involved nine pins, rather than the 10 of today.
The game enjoyed widespread popularity that stuck following the invention of the automatic bowling pin spotter in the 1940s. This little creation revolutionized the game and made it much easier for frames to be reset. The game has become so popular, in fact, that bowling pin set ups can now be found in almost every country in the world, with an estimated 95 million fans across the globe.
The standard bowling pin of today has come a long way, as well. Rather than stone or crude wood, a typical American bowling pin is made out of fine maple wood. This type of pin is created using a lathe to form the shape. Once this is done, the wood is coated with plastic and then covered with gloss. The idea is to create a uniform set up that is fairly standard from alley to alley.
The American bowling pin is a pretty strict creation. The standards set by the American Bowling Congress call for very stringent specifications. A standard bowling pin stands precisely 15 inches in height and is not more than 4.75 inches wide at its fattest point. They weigh in at less than four pounds a piece.
Although the standard American bowling pin is what is found in most alleys, there are other options out there in pins. The games played with them are a bit different, but they still revolve around the same concept of bowling to knock them down. Other types of pins used in bowling games include the candlepin, the duckpin and the set up for five-pins.
Bowling is a sport that has been enjoyed by people through the ages. From the days before recorded history to the modern, computerized alleys of today, the heart of the game has always involved a bowling pin in one form or fashion.
