Abstract: The present invention concerns a device for a multicopter that allows the multicopter to move without tipping over. This device generates propulsion according to the x- and/or Y-axis using the air displacement of the drive propellers and/or an additional drive device.

Abstract: An improved means of joining two different kinds of anchoring elements, at least one of which is flexible, each equipped with anchoring means in such a way that when the two surfaces are positioned against each other, they grip and clamp together.

Abstract: The invention relates to an improved multi-purpose tile system and the associated tiles, allowing a simplified coupling in multiple configurations and angles of approach, while ensuring a reliable coupling once secured.

Abstract: An improved assembly of joining two different kinds of anchoring elements, at least one of which is flexible, each equipped with anchoring in such a way that when the two surfaces are positioned against each other, they grip and clamp together.

Abstract: A click floor system can provide reversibility in combination with improved waterproof flooring utilizing bamboo, plastic, or other waterproof materials. The plank can include a veneer layer adhered to two surfaces of a waterproof core and a first waterproof adhesive layer that bonds the veneer layer to the surfaces of the waterproof core.

Abstract: The invention relates to an assembly of one or more pegboards and beads, adapted for modular connection to each other and other components.

Abstract: The present invention concerns a locking connector that makes it possible to connect different elements together in a two-step way. When connecting the two elements, in the first step, one element will be attached and blocked via a part to the second element and locked in the second step. As a result, the housing elements are connected in a secure manner and can no longer be disconnected from each other without additional action by the user.

Abstract: The present invention relates to face mask with a formed air duct, which makes it much easier for the user of the face mask to breathe. The facial layer of the face mask is provided with an extra piece. This support layer is located at the level of the chin of the skin and contacts the face layer in such a way that an air duct is created between the face layer and the support layer. Also, a filter can be fitted in this air duct.

Abstract: The invention provides a continuously variable transmission (CVT) system comprising a transmission means, connected to an input shaft and comprising at least a driving gear capable of rotating around its center, said center capable of rotating around a center of a virtual trajectory; a gear ring, engaged with said driving gear, capable of eccentrically rotating around said center of said virtual trajectory; a blocking means, engaged with said gear ring, comprising a set of blocking elements adopted to block the rotation of said gear ring and which elements are suitable to move; and an output shaft, connected with said driving gear. The invention further provides the use of such a CVT system in large vehicles and windmills.
