A lot of times, we are stuck out in public without our phone chargers handy. This leaves us vulnerable especially when we need to make an important call. This idea about a twirling battery is really cool. The concept is to simply twirl the cell phone battery around a finger a few times for a quick bit of juice to send a text or make a call. 130 twirls will give you approximately two minutes of talking time. The same idea could also be applied to batteries for other devices.

The idea is to create a fingerprint scanner able to tell the difference between living and dead tissue, preventing the use of a severed digit being used to foil fingerprint scanning devices. Fingerprint scanner able to identify dead tissue The scanner will work by reading the difference in the amount of light absorbed by living tissue versus dead tissue. The amount of light absorbed by a living finger will vary, changing from 550 nanometers when it is first placed on the sensor...

FlipFold is a simple device for folding clothes. It represents three cardboard pieces tied with a rope. It is five years since the FlipFold device has been patented. It is sold around the world through the site and major retailers such as Target and Eckerd Drug Store. The gadget is heavily oriented to shops and clothing manufacturers. It is already used by such famous brands as Nike, Sports Authority, Federated Department Stores, Bass Pro Shops, and even FBI.

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.

The idea is to create a new device which will be small enough to be injected into the eye, where it will be maneuvered to deliver drugs more effectively. The device will be controlled electro-magnetically to the desired location of the eye, where it will then deliver a capsule of medication or remain in place for a long period of time, delivering prolonged treatment. It can then be removed from the eye with a magnetic needle. Such a delivery system could be particularly...

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...

My idea is to create a mobile device which can be used by deaf and hearing-impaired people. I suggest creating a tool which would be integrated to any high-end mobile phone with a video camera. The tool would be based on motion detection technology, i.e. it would be possible to identify American Sign Language (ASL) and transmit video images over cell networks in the US.

I want to have a smart fence which can sense the difference between the rustling of leaves or a person skulking around the area. There will be a small low power device to be attached to a fence or other object or just be placed on the ground. It will use seismic sensors to distinguish between different types of movements. An alert will be sent wirelessly to the command center under certain conditions.

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...
