ATHIRA: .............RED TACTON..........

CHPC classes restarted after the vacation. We were all engaged with some tasks. First task was to install octave in all the systems of L3 lab. We could install octave successfully on most of the systems but there was problem of login in some systems.

Next sir asked us to do an octave code to perform selection sort. It was required to accept the numbers in a file, save it and then load it in another file to sort. Wikipedia helped me to understand the logic behind selection sort. Just go through the Wikipedia page on selection sort at the link given here.

When this task was completed sir asked us to do the same code with random numbers and calculate the time.

Then came the real task for the day. We were to make a presentation on any topic we like in two hours and present it in groups of two. The first topic that stoked my mind was about RED TACTON. This is in fact a very interesting and a fast developing technology. This is being developed at the NTT lab , Japan.

RedTacton is a Human Area Networking technology, which is under development, that uses the surface of the human body as a safe, high speed network transmission path. It is completely distinct from wireless and infrared technologies as it uses the minute electric field emitted on the surface of the human body.A transmission path is formed at the moment a part of the human body comes in contact with a Red Tacton transceiver. Physically separating ends the contact and thus ends communication Using Red Tacton, communication starts when terminals carried by the user or embedded in devices are linked in various combinations according to the user's .Communication is possible using any body surfaces, such as the hands, fingers, arms, feet, face, legs or torso. Red Tacton works natural, physical movements.

Using a new super-sensitive photonic electric field sensor, Red Tacton can achieve duplex communication over the human body at a maximum speed of 10 mbps

The Red Tacton transmitter induces a weak electric field on the surface of the body. The Red Tacton receiver senses changes in the weak electric field on the surface of the body caused by the transmitter .Red tacton relies upon the principle that the optical properties of an electro-optic crystal can vary according to the changes of a weak electric field. Red Tacton detects changes in the optical properties of an electro-optic crystal using a laser and converts the result to an electrical signal in a optical receiver circuit. The transmitter sends data by inducing fluctuations in the minute electric field on the surface of the human body. Data is received using a photonic electric field sensor that combines an electro-optic crystal and a laser light to detect fluctuations in the minute electric field.
