Abstract: Interactive systems can include various components that are packaged together and easily assemblable. An interactive system can comprise a mount, a display device, a projector, an input device, and a processing device. The display device, the projector, the input device, and the processing device can together provide an electronic display system, while the mount can carry these other various components and assist in connecting them to one another. The mount and the other components of the interactive system can be conveniently packaged and sold as group for convenient installation by one or two persons.

Abstract: A hose includes at least an inner-layer tubular member, an intermediate layer, and an outer-layer tubular member. Both the inner-layer tubular member and the outer-layer tubular member are made of plastics. The intermediate layer is formed by wrapping a net. An outer surface of the intermediate layer is provided with a helical structure made of plastics and the outer-layer tubular member encloses the helical structure. The helical structure has a mechanical strength greater than the outer-layer tubular member. Since both the helical structure and the outer-layer tubular member are similarly made of plastics, the bonding strength therebetween can be enhanced. When the hose is subjected to bending, the helical structure helps to prevent the hose from being compressed and deformed, thereby maintaining the inside diameter of the hose to ensure smooth flow of liquid or gas through the hose.

Abstract: A container caddy for use with a shopping cart. The container caddy includes a container receptacle and an attachment bracket. The attachment bracket includes a positioning element and a locking element. The attachment bracket can be positioned on the shopping cart and the container receptacle can be maneuvered by the positioning element until locked into place by the locking element.

Abstract: A cart for transporting materials along a floor having a base positioned parallel to the floor. Positioned above the base is a rectangular cover having a first side edge, a second side edge and a back edge defining three sides of a rectangle. A first side support, a second side support and a back support each extend from the base to the cover. Four vertical supports extend from the base to contact the cover at four points substantially aligned with a first diagonal of the rectangle.
