Smart phone is the attraction of many people because of its multi features and applications. But the most important problem is severe battery drain and it needs many time charging in a day. Apple, BlackBerry, Samsung and other global brands have come up with powerful mobile operating systems such as Google’s Android, Nokia’s Symbian, Apple’s iOS, etc, that allows users to play games, listen to mp3s, snap pictures, have access to the Net and even stream videos. This causes severe battery drain due to the running of many applications in the phone along with power use for signal capturing. This problem is severe when travelling so we have to carry one back up device also. But we can manage the situation. Follow the 10 tips to keep the Smartphone alive.
Mobile phone battery is a high efficient Lithium Ion or Lithium Polymer battery that can deliver much power for long time. In an ordinary Mobile phone, a fully charged battery can power up to 3 or 4 days. But in Smart phones, the battery drains too fast because many applications are running simultaneously. To extend the life of battery we need to know some facts about the charging because the most important cause of battery breakdown is improper charging.
Bluetooth is the miniature wireless transmitter and receiver used as an interface to access LANs, PSTN, Mobile network and portable handheld devices. Bluetooth can communicate with the Bluetooth enabled devices through a short range network called ”Piconets”. When the Bluetooth enabled device enters the proximity of the piconet, it establishes connection with the Bluetooth. It is very useful for hands free communication in hand held devices. The technology of Bluetooth was named after Harald Blaatand Bluetooth II, the king of Denmark.
Mobile phone battery requires only two pins for charging, then why there is a third pin? The question is definitely a curiosity generating one. The third pin called BSI pin performs very important functions and act as an interface between the Mobile phone and the Battery. When the battery is removed, without switching off the Mobile phone, the BSI circuit is first interrupted which convey the information to the processor to shut down all communications to prevent damage. To communicate with the BSI, the battery pack also has a BSI pin. BSI stands for Battery Status Indicator or Battery System Indicator.
Human personality is reflected in the way of behavior, daily activities and doing competitive works. Human personality can be classified into Type A, Type B and Type AB personalities according to researchers. Type A behavior (TAB) or personalities have something to do with being competitive and most of them are workaholics. Type B personalities on the other hand are generally patient, relaxed, easy-going . AB personalities have mixed profile and cannot be clearly categorized as either Type A or Type B.
Not always, but only when handled carelessly. Shock induced muscle tetany is the most important effect of current on the muscles. If a person touches the energized conductor, fore arm muscles contracts forcefully and fingers bend. So the person involuntarily holds the conductor. Therefore the victim will be unable to take the hand from the conductor.
As you know, electricity is the flow of electrons through a conductor from its source to the destination. If the conductor offers less resistance, the flow current will be fast and if the conductor has some resistance, the flow of electrons will be obstructed leading to slow movements which generate heat through friction.
Human skin is a semiconductor for electricity and current passes through the body to the ground just like the flow of current through the electric wire. This flow of current causes burning and shock. If the skin resistance is low, the chance of shock hazard is very high. Some people are more sensitive to current while others are less sensitive. Electrical safety measures are necessary while dealing with high voltage AC available from the power grid. Ignorance can lead to a fatal shock or fire hazards.
Remember, Electricity travels at the speed of light. Its flow is around 299,460 kilo meters per second so you will not get time to react because you can’t move faster than electricity. So the best way is staying out of its way.
This simple alarm can be used to detect the movement of human beings at a distance of 10 meters.It works both day and night and beeps shortly when there is a human movement through its detecting range. It is ideal to monitor the entry passages, stair case, corridors etc. It is highly useful to monitor the human movements in Flats, Multi storied buildings, Shops etc. A relay can also be connected for activating lights, electric alarms etc. It can be used as a Personal alarm during journey to protect luggage.
