 We're here at the Geneva Inventions Fair where over 700 inventors from 40 countries around the world have traveled to Geneva to show off their innovations. Let's have a look. I'm here to present TWICE. TWICE is a lowerland exoskeleton that enables paraplegic people to stand up and walk again. It's made of a structure which acts like the bones of a human leg and actuators like electrical motors which work like our muscles and it actually helps these people moving again. So it mobilizes the legs in order to provide movement. So basically the person uses crutches to balance and on the crutches there are buttons that the person can use to give input to the device and an express their intention of walking and also changing between modes like walking, climbing stairs or sitting down. So this my invention is when it snows you can stick on your car seat with no need to go out and just by pressing a button you put on and put on and take off there's no change. With this invention, every time there is a drop of tension or a drop of the current it is in the car seat, in this case it disconnects all the devices and it takes off the car. First of all it takes off and it forms a wave of shock with an autonomy of 6 hours to avoid the Africans from turning on the engine. I am the designer of this airbub system which is a system that allows the optimization of a large irregular dam that is particularly suitable for dams in the coast of the boats under the float but also in a dam for canalization or to reserve hydrocarbons. A dam that would have flowed the boat in 10 minutes to a quarter of an hour allowed us to navigate for more than 24 hours without using the pump on board and without assistance. We are distributing a new kind of car for emergency which can transform water into drinkable water. Sea water, lake water, river water and the truck can be brought into a disaster area by helicopter so within half an hour that the truck is there we can start to distribute water for people around.
