For many, the sound of the drill is a big cause of anxiety when it comes to visiting the dentist. I have an idea to create a device which will cancel out the noise of a dentist's drill helping people overcome their fear of a check-up. This new device will allow patients to listen to music on an MP3 player, while the sound of the drill will be blanked out. Patients will still be able to hear the dentist's voice because not all sounds are to be filtered out. The device will be...

It would be cool if our mobile phone or PDA beeped when there was our friend nearby. It seems to be possible using Bluetooth technology.

You can now use a bicycle to go to the place which seems to be reached only by a tractor. Downhills and parks in winter are full of cyclists who do not want to stop cycling. Some of them buy snow tires; the others use ski-bikes (special bikes with skis instead of wheels). Unfortunately, in the first case grip of wheels with snow is not so good and in the second case there are no pedals which are the main bicycle attribute. A Canadian innovation company suggested a winter kit...

I travel a lot and often use my digital camera to take pictures of landmarks and the landscape. All the pictures are time stamped to tell me when they are taken but there is no information on where they are taken. I think that building GPS system into cameras could be cool. This will help to store the location, direction and possibly the pitch and also will add more life to the pictures. By the way, it may be possible to create a 3D map using this technique in future.

A designer from India invented a unique jeans design, which helps to protect wallets from pickpockets. The main feature of these jeans is that there is a copper wire in their seams. The wire is connected to a special device consisting of capacitors, a 3-volt battery and a magnetic switch. This electric device is placed in a case and can be activated by the user at any time. Its mechanism of action is simple - once a thief feels about for the wallet in your pocket, he is...

An entrepreneur from Arizona decided to use polymers to create a product that literally saves human health, thanks to its cooling properties. He suggested sewing polymers inside the material and creating stylish scarves, which can cool in the hot weather. The principle of the cooling scarf is the following: when it becomes wet, polymers absorb moisture and through the natural process of evaporation create a cooling effect in the area of the carotid arteries, vessels of back and...

Do you still use rake to pick up leaves in your yard? I suggest a new idea how to make your yard clean easily. What about a vacuum with a bag attached which you can place on your back? It could look like an industrial blower but it would pick the leaves up instead of blow them away. It could have either electrical or gas engine. Such a vacuum will definitely save time and make the yard work a little easier.

I want to create a mobile phone application for those who don't want to waste time standing in line. One will have a possibility to check as well post line conditions with the app running on a mobile phone.

If you are tired of the same old boring wallpaper designs on your wall then you'll find my idea interesting. I suggest creating digital wallpaper. There would be digital paper or some kind of very thin screen on your wall. A small computer box would also be on the wall. You would be able to download any image you wanted to see on your walls. In such a way you could change wallpaper every day.

The idea is to develop an animated sign language translation system that will automatically convert words into gestures for deaf viewers, which could help improve the spread of information during disasters. Subtitles are not always enough for people who use sign language as their main form of communication. The new system will be able to convert the text into sign language delivered by a suit-wearing avatar in a virtual newsroom. The system will also able to use synonyms to replace...
