WI-VI (WIRELESS VISION)

 Wi-Vi is one among the foremost modern technologies that modifies the Wi-Fi technology to form the concept of wireless vision possible.

The main idea behind this Wi-Vi is tracking and manipulation of reflected Wi-Fi Signal. There-fore it is also called as adaption of SONAR or RADAR.

In earlier technologies to map over the obstacles we need an array of special antennas, but it is more and more expensive. Here Wi-Vi uses simpler devices to receive signals. Click here to continue reading

UNDERWATER WIRELESS COMMUNICATION

 Today, The technology of Wireless communication  has become part of our daily life, but still the idea of wireless undersea communications seem unachievable. However, several researches are going over a decade on designing the methods for wireless data transmission underwater. Our knowledge and understanding about the world’s water resources mainly oceans which covers the major part of our planet, rests on our ability to gather information from remote undersea locations. In the past decades, the major discovery which we all are familiar is the remains of TITANIC, was made using cabled submersibles. Although such system remains very important, if high-speed communication link is to exists between the remote end and the surface, it is natural to wonder what one could accomplish without the use  of heavy cables. Here comes our topic , Wireless Underwater Communications.  With the help of sensor technology and vehicular technology, wireless communications will enable new applications ranging from environmental monitoring to gathering of oceanographic data, marine archaeology, and search and rescue missions.

SINGLE-ELECTRON TRANSISTOR

To avoid problems like power consumption challenges, high-performance, high-density chip design, and faster and more processing in transistors Mitri Averin and Konstantin Likharev proposed a new three-terminal device called single-electron tunneling transistor. Two years later Theodore Fulton and Gerald Dolan at Bells Lab in the US created this device and demonstrated its working and operation.
