Red Taction

Red Tacton 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 RedTacton transceiver. Communication is possible using any body surfaces, it also works through shoes and clothing as well. When the physical contact gets separated, the communication is ended.
Using RedTacton-enabled devices, music from a digital audio player in your pocket would pass through your clothing and shoot over your body to headphones in your ears.


Hawk-Eye is a complex computer system used in cricket,tennis and other sports to visually track the path of the ball and display a record of its most statistically likely path as a moving image. It is also used in some instances to predict the future path of a ball in cricket. It was developed by engineers at Roke Manor Rearch Limited in the UK, in 2001. All Hawk-Eye systems are based on the principles of triangulation  using the visual images and timing data provided by at least four high-speed video cameras located at different locations and angles around the area of play. The system rapidly processes the video feeds by a high-speedvideo processor and ball tracker. A data store contains a predefined model of the playing area and includes data on the rules of the game.

Hyper Sonic Sound Technology

Hyper Sonic Sound (HSS) is a sound-generation technology that broadcasts your message directly to your intended audience. In contrast to conventional loudspeakers, HSS technology uses a directional ultrasonic column to produce sound exactly where you want it. Sound does not spread to the sides or rear of an HSS unit, eliminating the problem of uncomfortable and unwanted noise pollution produced by conventional speakers. Sound is directed only where it is intended to go. Visualize two people standing four feet apart at an art exhibit. One patron listens to a biography of a sculpture artist, while the other contemplates a painting in complete silence! HSS is like handing someone a set of head phones. By focusing sound in a tight column, HSS allows you to restrict sound to a specific area without imposing on nearby speaker focused on the area in front of only directory users to hear the corresponding audio.
                             The HSS Directional Audio System can operate in Direct Mode, a clear line of approach from the HSS unit to the target listener, and in Virtual Mode, projecting sound onto a sign, display or other object creating a Virtual Speaker.


Sound Bullets
Jack the sound level up to 145 decibels, or 50 times the human threshold of pain, and an offshoot of hypersonic sound technology becomes a non lethal weapon.
  Automobiles - HSS announcement device in the dash to beam alert signals directly to the driver
Audio/Video Conferencing - project the audio from a conference in four different languages, from a single central device, without the need for headphones.
 Paging Systems - direct the announcement to the specific area of interest
  Retail Sales - provide targeted advertising directly at the point of purchase
   Military Applications -ship to ship communications, ship-board announcements,

Grace Murray Hopper

Grace Murray Hopper(1906 - 1992) was an American computer scientist and United States Navy officer. She was one of the first programmers of the Harvard Mark I computer, and developed the first compiler for a computer programming language. She conceptualized the idea of machine-independent programming languages, which led to the development of COBOL, one of the first modern programming languages. She is credited with popularizing the term "debugging" for fixing computer glitches . Because of the breadth of her accomplishments and her naval rank, she is sometimes referred to as "Amazing Grace".
