With many chain stores now having "rewards" membership cards, it is becoming a hassle to search through your wallet to find the right one, especially if you are at the checkout with a line of people behind you. My idea, that as far as I know does not exists, is a "smartphone" app that would contain all of your rewards/wholesale club membership cards. This app would already link your information with all the stores that you are a member of and frequent, eliminating the need for a plastic...

My idea is to create stations for loading media files to different devices such as mobile phones, MP3/MP4 players, flash drives, etc. A song, video, audio-book, ringtone, whatever can be easily copied to any digital media equipped with USB-port, infrared port or Bluetooth. Such stations are supposed to be found in crowded places like airports, railway stations, shopping centers, movie theatres and other.

Why not create an electronic lamp which dynamically matches the color of whatever it stands on? It would be some kind of chameleon lamp :). The lamp would light the surface underneath it with two hidden white LEDs and then use an optical sensor to determine the correct color. It would match this color by adjusting the shade of numerous multi-color LEDs imbedded in its frame.

My idea is to create mobile application which will help children with autism to develop communication skills. The application will be based on Picture Exchange Communication System, i.e. it will help children to build messages from pictures and send them to each other. It will also contain a vocabulary consisting of words learnt by a child. The vocabulary could be easily updated as well as new pictures could be added to the application.

My idea is to provide cell phones with a functionality to read and record weather data such as temperature, humidity, air pressure and wind speed. This functionality will help us to gather more accurate data then any weather station could offer.

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.

My idea is to create a mobile phone application based on GPS which will help to define single people within a radius of 0.5 - 0.7 miles. It will be of great help not only for pickups but also for people who are eager to make the acquaintance. The application will also have a chat function so as it is possible to send short messages to each other and make an appointment.

It would be great to have a TV set that would allow two people in same room to watch different TV programs. My idea is to create a two-sided TV screen for this. It would have separate remotes and possibly speakers inside remote or simple headphone speakers. With such a TV set couples won't need to have extra TV in another room.

My idea is to create a mobile application integrated with a database of public lavatories within a city/country/state/etc. After you define your location the application will return the list of the nearest lavatories. It seems to be very convenient. By the way, the database should be updated on a daily basis.

I want an audio file on my phone which will frighten off mosquitos within a radius of 3.5 feet. A human won't hear anything but mosquitos will. The sound will be similar to the buzz of mosquito male which mosquito female try to stay away from.
