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.
Soldering is the process of joining two or more similar or dissimilar metals by melting another metal having low melting point. The materials and tools that are required in the process of soldering are solder, flux, knife, blade, and soldering iron and nose plier.
Soldering fluxes
In order to make the surfaces accept the solder readily, the component terminals should be free from oxides and other obstructing films. Soldering fluxes are used to clean the oxide from the surface of the metal .The leads should be cleaned chemically or by scrapping using a blade or a knife .Small amount of lead should be coated on the cleaned portion of the leads and the bit of the soldering iron. This process is called tinning. Zinc chloride; ammonium chloride and rosin are the most commonly used fluxes.
Solder
Solder is used for joining tow or more metals below their melting point. The popularly used solder are the alloys of tin (60%) and lead (40%) that melts at 370 degrees Fahrenheit and solidifies when it cools .Most of the solder wires are flux cored type. When such solder wires are used, extra soldering flux is not required.
Soldering tools
Soldering iron is the most important tool used for soldering. It is used to melt the solder and apply at the joints in the circuit. It operates in 230V mains supply. The power ratings of the soldering iron are 10W, 25W, 35W, 65W and 125W etc.The iron bar at the tip of it gets heated up within a few minutes .Soldering gun is a gun shaped soldering tool used especially when more heat is required .Its trigger is a switch that controls the ac voltage to the circuit.
Desoldering
It is the removal of solder from the previously soldered joints. Desolder pump is a commonly used device for this purpose. When the solder melts by the action of the soldering iron, a trigger on the desolder pump should be activated to create a vacuum. This vacuum pulls the solder into the tube.
Soldering rules
There are various rules for the soldering process. They include the following-
- Select the proper soldering iron for the work.
- Tin the bit before soldering.
- Keep the tinned bits always clean from oxide formed while soldering.
- Do not over heat the PCB and devices.
- Do not use excess solder or flux.
- Clean the surfaces of the leads to be joined using a blade.
Procedure for soldering
The procedure that is involved in soldering process is as follows-
- Make a lay-out of the components in the circuit. Plug in the chord of soldering iron into the mains supply to get it heated up.
- Clean the component leads, using a blade or a knife and bend them according to the needs. Apply a little flux on the leads. Take a little solder on soldering iron and apply the molten solder on the leads. Care must be taken to avoid the components heated up.
- Mount the components on the PCB, apply flux on the joints and solder the joints. Soldering must be done in minimum time to avoid dry-soldering and heating up of the components.
- Wash the residues using water and brush.
- Desolder the soldered circuit, if necessary, using soldering iron and the desolder pump.
Computer is a machine which works accurately and very fast. With this we can solve all complicated problems in short time with accuracy. Human beings cannot do repeatedly work with the same efficiency but computer can do the same work with no of times and any length with same accuracy. In computer we can store lot of data and programmes in it we can save data and display whenever we want.
The main parts of computer are:
C.P.U (Central Processing Unit)
Monitor
Key board
Mouse
Working of computer:
Computer works on the principle of Input---Process---Output
The data and instructions given to the computer is through input devices this is processed in C.P.U and results will be displayed to us through the output devices.
Input Devices:
Input devices are keyboard, Scanner, Microphone, Web camera and Mouse e.t.c
Keyboard: We give the instructions to the computer by typing the data through this keyboard.
Mouse: This is used to select item on the monitor and gives instructions.
Scanner: We can scan and save the pictures in the computer.
Microphone: This is used to record the sound.
Web Camera: This is used to record the scenes.
Processing:
Analyzing the data instructions and giving results is known as Processing.
This analyzing is done in the C.P.U it reads the instructions and processes the data. This is having three units namely Control unit, Memory unit and Arithmetic Logic unit. When instructions are given to computer by input devices these are analyzed by control unit as these are stored temporarily in memory unit. These analyzed signals are sent to arithmetic unit which finds solutions for mathematical problems. After finding solutions results are sent through output devices.
Output Devices:
Output devices are Monitor, Printer and Speakers.
Monitor: This is used to see the data, graphs, Pictures etc this looks like a Television.
Printer: This is used to print the data on the paper.
Speaker: This is used to emits sound from input devices.
Uses of Computer:
Communication has becmoe fast because of computers and satellites. We can work speed, accuracy and store data in it.
