This device is a wheelchair steering "wheel" in the form of a dental retainer instrumented with sensors that are activated by a tongue piercing. Georgia Institute of Technology engineers devised the Tongue Drive System prototype for people with high-level spinal cord injuries. From Wired UK: The output signals from the sensors are wirelessly transmitted to an iPod Touch or iPhone. Software installed on the Apple device works out the relative position of the magnet with respect to the array of sensors in real time and interprets the user's commands. This information is then used to control the movements of a cursor on the computer screen or to substitute for the joystick function in a powered wheelchair… The system can be trained with multiple commands -- unlike the common sip-n-puff device that acts as a switch controlled by sucking or blowing through a straw.

party receiver oct 26, 2006 party receiver by jinseup ted shin from usa designer's own words: This is a small electronic device that receives an FM signal from your music player, i.e. ipod, cell phone, cd player or any device equipped with an FM transmitter. At a party it is always hard to control the music you play, the sound of volume is not playing evenly throughout the place and you always have to have a big and bulky stereo system.

7th Grader mimics Nature 13 year old copies Nature to Improve Solar Performance Thirteen year old Aidan Dwyer was walking in the woods in Upstate New York in the winter and noticed a spiral pattern to tree branches. Aidan realized the tree branches and leaves had a mathematical spiral pattern that could be shown as a fraction. After some research he also realized the mathematical fractions were the same numbers as the Fibonacci sequence. "On the oak tree, the Fibonacci fraction is 2/5, which means that the spiral takes five branches to spiral two times around the trunk to complete one pattern.

Autonomous Quadrotors Fly Amazing Formations | Autopia Roboticists at the University of Pennsylvania’s GRASP are able to get as many as 20 of their autonomous microcopters to fly in formation and perform complex maneuvers flawlessly. In an impressive new video, the GRASP — General Robotics, Automation, Sensing and Perception — team makes their swarm of flying microbots flip, change direction, navigate through obstacles and even fly figure-eights with jaw-dropping agility and precision. GRASP has since 2010 made remarkable advancements in the capabilities of their tiny quadrotors, developed by Kmel Robotics, and documented them with a series of videos showing bots flying hoops and building a tower-like structure. The lab is developing the ability to fly autonomously in formation, communicating with each other to maintain position. Last year the team demonstrated a basic formation flight with a lost-communication demonstration where one of the aircraft drops out on its own.

Despite its incredibly low density, aerogel is one of the most powerful materials on the planet. It can support thousands of times its own weight, block out intense heat, cold and sound – yet it is 1,000 times less dense than glass, nearly as transparent and is composed of %99.8 air. The lowest-density silica-based aerogels are even lighter than air. Despite its fragility in certain regards and its incredible lack of density, aerogel has amazing thermal, acoustical and electrical insulation properties as illustrated by the images here. A single one-pound block can also support half a ton of weight. NASA continues to find new space-based applications for this incredible material.

What Does Your Body Language Say About You? How To Read Signs and Recognize Gestures - Jinxi Boo - Jinxi Boo Art by LaetitziaAs we all know, communication is essential in society. Advancements in technology have transformed the way that we correspond with others in the modern world. Because of the constant buzz in our technological world, it's easy to forget how important communicating face-to-face is. When conversing old-school style, it's not only speech we verbalize that matters, but what our nonverbal gestures articulate as well. Body language is truly a language of its own.
In cooperation with the U.S. Consumer product Safety Commission (CPSC), Strong Force, Inc. urges purchasers of NeoCube magnet sets to immediately discard the sets, including all of the component magnets. The CPSC has warned consumers that if two or more magnets are swallowed, they can link together inside a child's intestines and clamp onto body tissues, causing severe injuries. Internal injury from magnets can pose serious lifelong health effects. NeoCube sets contain small high-powered magnets and are accordingly labeled “Not intended for ages under 14.” These sets and all of their component magnets must be kept away from children under the age of 14 at all times. The NeoCube
Here's what Felix Klein had in mind back in 1882, when he first dreamed of a closed, one-sided surface. It's elegantly curved, with a side loop making a transverse puncture at the nexus. An Acme Classical Klein Bottle is big enough to show to a classroom, yet slides easily into your backpack for trips across the Yukon. With its center of gravity directly over its base, your Acme Classical Klein Bottle stands on its own -- no need for extraneous stands, complex levitation apparatus, or unreliable anti-gravity fields. Indeed, in the absence of external forces, its polhode rolls without slipping on the herpolhode lying in the invariable plane. Unlike those inferior 4-dimensional Klein Bottles, you can fill your ACME Klein Bottle with water! Classical Klein Bottle
Secret Worlds: The Universe Within View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons.
