What is SAR Value

What is SAR Value SAR stands for specific absorption rate, is the amount of Electromagnetic energy that is observed by a unit of mass of exposed tissue of a person. Our body has a limitation to observe the radiation. The governments of every country has defined maximum SAR levels (1.6 weight power per kg in India) for RF energy emitted by mobile devices. The SAR value is divided into two part. When we are talking to someone in this case our phone is close to the head so the Radiation will be more on the head than on the body. Every phone has its SAR value which must be under the limit. Our tissue is not capable to handle much radiation. You have observed that during talking on phone more that 1 and half hours our phone heats up and also we feel the temperature increased around the ear. As advised to not talk more that than half hours and if possible use the wired headphone rather than wireless or Bluetooth. How to protect yourself from the Mobile phone radiation 1.     Do not

How The Face Recognition-System Works   The first semi-automatic face recognition system was developed by Woodrow W. Bledsoe under contract to the US Government. This system required the administrator to locate features such as eyes, ears, nose and mouth on the photographs.   World’s first face recognition technology for mobile devices with camera has been presented at the “Security show Japan” in 2005. The technology named “OKAO Vision Face Recognition Sensor” was created by OMRON Corporation. More than a decade this type of biometric recognition system was used on mobile devices but it never has been so popular since 2017, November 3rd – the date when iPhone X was released.   Revolution in Mobile Phones Facial Recognition-   Why iPhone X face recognition technology is so different from others? First of all, the new model’s iPhone True Depth camera system consists of multiple innovative technologies:   ·          Infrared camera – reads the dot pattern, captures an
