Many technologies have changed the difficulties of the human in many ways. Such technological innovations have made many breakthroughs. But they may also have some bad effect if they are implemented and used without care. One of such technological innovations is cyborg. The cyborgs are referred to as cybernetic organisms which can act like a normal human or a part of a human. The cyborgs have natural and artificial components in them. The cyborgs have good role in many fields. They assist us in many ways in works in which we cannot employ a human. In the case of nuclear reactors the human cannot directly get access to the nuclear materials. Instead we can use some cybernetic organism called cyborg to do some activities. The cyborgs are constructed by strong physical body and high intelligence such that they can think very fast when compared to human. The cyborgs are integrated with artificial intelligence. They can be used in military to create a super soldier. Such cyborgs cannot be stopped by human force. They are far better in both physical strength and logical reasoning when compared to the human race. The cyborgs are also applied in medical field for substituting the amputated limbs of human. These cybernetic organisms are having more advantage but they must be used with care.

A sense of Touch

Touch is a physical feeling which can be felt by living beings and it is especially applicable to human. We did not expect a touch can make a non living thing to do work before hundred years. But nowadays the touch makes many things simple in our life. The touch screen is that non living thing which is doing many works in our day today life with the help of a small touch. This touch screen is a simple and user friendly physical interface. This technology is applied in music players and mobile phones. The touch screen is nowadays used in many ATM machines for selecting various options specifies on the screen of the ATM machine. In the case of mobile phones a pointed material called as stylus is used for selecting various options in the touch screen. In some mobile phones having this technology the touch screen can recognize the handwriting when written using a pointed device or stylus. The touch screen works by the electrical signals. When a person touches the touch screen the electrical signal form that particular region of the touch screen is generated. The particular area where the person touches the touch screen is considered to be a button. This also implemented in personal computers for replacing the input devices such as mouse and keyboard.

Remebering the face

In today’s world security is main concern for every place. The unauthorized of entry of unknown people into an office creates huge risk. This will lead to loss of security. We cannot manually monitor entry of people and authorizing them. Security officials cannot check everyone entering into an office. It is a time consuming process too. Some technologies such as face recognition and fingerprint detection systems help us to do such security operations. The face recognition system helps in differentiating the face textures of various faces. This will help an organization to be safe by allowing only the authorized persons of that organization. Even within some restricted areas the entry of every person can be restricted by this system. This technique is also applied in some laptops. This makes only the owner of the laptop to access it. Every point of the face is observed by the technique for recognizing the face of the person who wants to enter into an area of an organization. The facial features like distance between the eyes, color of eye, cheeks are checked. The nodal points is the important feature which helps in recognizing the face. The simple text password can be copied by other person. But one’s face texture cannot be copied easily.

B for communication

Bluetooth is a method of communication for sending and receiving information such as messages, files and data within short range of distance. Initially the Bluetooth technology was used in the place of RS232 data cables. The transmission through this technology is possible within hundred meters of distance between two devices. The transmission beyond this distance is not possible. The Bluetooth technology is widely spread among the people in this world. The mobile technology has made the Bluetooth technology very familiar among the people. Frequency-hopping spectrum is the principle applied in this technology. The frequency-hopping spectrum is a radio technology. It disintegrates the data to be transmitted before transmission so that the data can be sent as many parts. Bluetooth technology can be used by Bluetooth enabled devices to transmit data. The important application is mobile phone. The laptops and personal computers can also have Bluetooth facilities to transmit data to other Bluetooth devices. The power consumed by the Bluetooth technology is not very high. The rate of transmission of data is much faster when compared to copying data to a memory card from a personal computer. So the time consumption is also very less for this technology. This is why people prefer Bluetooth over data cables.
