It would be really great to have a tool to make retrieving submerged golf balls faster and easier. The device could be made of a series of mesh discs mounted on a carbon steel axle weighted at either end. It would be pulled with a rope across the bottoms of golf course water traps. As the discs turn, the balls would be trapped between them, to be plucked out at the end of each traverse.

Why not equip a knee bandage with sensors? This will make it possible to monitor the knee's range of movement, enabling the patient and the doctor to keep track of the healing process over time. The bandage will consist of a bracket with sensors to measure and record the knee's range of movement, as well as its degree of rotation. The data will be recorded continuously and evaluated by software that will allow doctors to easily recognize trends and adjust the treatment if...

My idea is to create sensory equipment enabling people to share hugs across cyberspace. The idea can be implemented with so-called "hug-shirt" and a teddy bear. The teddy bear will be fitted with sensors to detect when it is hugged by a person. The sensation will be transmitted to another person via a special jacket fitted with heated copper wires.

I want scientists to discover a substance effecting powerfully on the biological clock. Eventually, this substance could be used to help workers on the night shift or frequent travelers better tolerate the variances in their schedules.

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.

To be sick is human but not all indispositions require attention and expensive doctor's help. Sometimes it is enough to find a pill in a medicine chest and take it. For me this can be a real trouble as it is difficult to remember all pill names and their prescriptions. I suggest sorting pills and putting them in different boxes with inscriptions such as: * "Help, I Have a Headache" box with paracetamol pills; * "Help, I've Cut Myself" box with antiseptic plaster; ...

Do you hate shoveling the walk-way, porch or driveway as I do? My idea is to lay small heated coils under the concrete walk way or driveway. The coils will heat the concrete or pavement above freezing temperature and will prevent snow and ice from building up. Such a solution will save your time and money as well as save you from slipping and falling.

I am a member of a soccer club. We have no real goalies there so the field players have to take turns in the goal. I always have the feeling that some people spend more time in the goal then others but I have no real proof. I suggest creating a device similar to a chess clock but with five and more buttons. If you're in the goal, you press your button so as it is easy to track your time there. I am sure that this device would have many other applications!

What if a remote control had a buy button on it? It would be very convenient to buy things which were in the commercials. To purchase something the user should push Buy button and then enter credit card numbers or passwords in the form on the TV screen. The good would be delivered at the address defined.

I am thinking of creating some fish saving device. It can be an aquarium which records the water temperature, ph level, oxygen level, amount of food eaten etc. and automatically fixes the problem by adding food and/or by adding oxygen or heating the water according to the settings defined.
