I suggest using a plastic metamaterial to build a cloak that makes objects invisible to sound waves. The cloaking device will be made of stacked sheets of plastic filled with holes that will be sized and arranged to redirect sound waves by either blocking them or absorbing them. The device will work for audible frequencies between one and four kilohertz, which is the same frequency as the higher two octaves on a piano.

The magnetic bike light will detach quickly and turn on automatically when attached to the frame. Designed to help prevent theft, the lights will be easily removable and pocket-sized, allowing them to be quickly detached and taken along when the bike is left unattended. They will fit an array of tube diameters, remaining securely in place and emitting a bright LED light from the sides as well as directly ahead. The lights can be placed anywhere on the frame, automatically...

The idea is to have a bicycle lock you can wear, eliminating the need to carry a heavy lock around your shoulders or on your bike frame where it can feel clumsy and cause scratches. It will be the first bike lock specifically designed to be worn on the body. The lock will be adjustable and easy to remove, in contrast to conventional bike locks which must be locked onto the body in order to be secure. The lock will be made to carry its weight on the user's hips and will have highly...

Happy clients result in new clients. This axiom was literally used as a basis for a new advertising campaign by LEO BURNETT ad agency. Creative Italian advertisers put unusual billboards with real people on them all over Milan. The idea is as follows: ordinary people (potential customers) ask and happy (real) customers answer. There are no lure, intrigue or deception... just an honest dialogue. Creators of such an unusual interactive advertising campaign actually asked real...

I suppose that microscopic worms could do a better job of detecting explosives than X-ray machines, metal detectors or bomb sniffing dogs. The tiny nematodes, known as Caenorhabditis elegans, have little scent organs on the sides of their mouths. Why not extract the receptors from the amphids and incorporate them into a device (so called bomb sniffing machine).

The tiny cam car key uses an infrared LED to create enough illumination to capture HD videos, even in the darkest corners. The tiny camera weighs under an ounce and measures only 2.5 inches on its longest side. Although it doesn't look much like a camera at all (instead resembling a remote car key), its features include motion-detecting activation, an 8 GB built in memory and audio recording capabilities.

It will be really great to have a robot which will be able not only detect motion through walls but also detect the breathing of a stationary person? Its primary goal will be to provide improved situational awareness to soldiers while keeping them out of danger. The robot could also be used in the civilian sector, allowing police and firefighters to locate people within buildings. The robot will travel on caterpillar tracks while the mounted RF scanner will transmit wideband...

The idea is to create a glucose sensor for diabetes sufferers which will use tear fluid instead of blood. This may soon eliminate the need for finger pricks. The device will be able to take a sample of tear fluid by a painless dab at the corner of the eye. The device's sensor will measure the amount of glucose in the tear sample which is supposed to be very similar to the amount of glucose in blood. Image: A - screen-printed electrical leads, B - an insulating layer, C - a...

A new line of avalanche airbag integrated clothing will make protection as easy as putting on a vest. The vest will use a nitrogen based airbag system that will be deployed by the wearer to release a pair of brightly colored bags. The bags will increase the wearer's surface area to help reduce sinking as well as will act a visual signs for rescuers. The vest will also include an array of pockets able to secure other gear, allowing the vest to replace a full backpack.

I am sure that those people, who are always losing their keys, will find this idea interesting. It would be awesome to have a fingerprint scanner right on a doorknob where a key hole was. You'd need to register your fingerprint on a microcomputer and then you would lock / unlock the door just putting your finger on the scanner.
