The present invention provides a snorkel having smaller respiratory dead space or volume. The snorkel includes a mouthpiece and a tube with an inhalation lumen and an exhalation lumen. A distal one-way inhalation valve is placed inside the inhalation lumen; and a distal one-way exhalation valve is placed inside the exhalation lumen. The invention also provides a method for reducing the volume of a respiratory dead space in a snorkel.

The present invention provides a building piece comprising a first wing, a second wing, and a flexible belt connecting said two wings. The first wing has a first front side and a first back side, and the second wing has a second front side and a second back side. At least two of the four sides each comprise a topographical profile or a landscape. In the present invention, the term 'landscape' can be used interchangeably with the term 'topographical profile'. The landscape on any one of the at least two sides can be reversibly interlocked, or is reversibly interlockable, to another one of the at least two sides.

The present invention provides a building piece toy including a first container comprising a first cavity with a first opening, a second container comprising a second cavity with a second opening, and a flexible belt connecting said two containers. The container is tapered monotonously in all dimensions from the opening to the rest of the container's body. Many of the building pieces are interlockable to each other, so a player can create toys with a shape of human, animal, or plant such as lobster, butterfly, peacock and chicken.

A modifiable boomerang comprises of a pair of wing blades which have a curved top surface and a flat bottom surface. The wings are connected together by a pivot bolt to form a boomerang whose angle can be adjusted to change the aerodynamics of the flying boomerang. A thrower can change the angle of a boomerang to change its flying pattern.

An autonomous vehicle is provided that includes an autonomous vehicle control system, a dialysis machine, and an interface providing an electrical communication between the dialysis machine and the autonomous vehicle control system. The dialysis machine is configured to perform a dialysis treatment on a patient while the autonomous vehicle is under the control of the autonomous vehicle control system. A vehicle is also provided that includes a navigation system, a dialysis machine, and an interface between the navigation system and the dialysis machine. The vehicle can be a car, a train, a plane, or another vehicle.

A magnetic floating paper towel holder consists of a magnetic stand that has magnetic blocks installed at four corners and four sides and a magnetic paper towel holder which has two magnetic wheels and one magnetic connecting tube. The magnetic polarity of the stand magnetic blocks, the magnetic wheels and the magnetic connecting tube is properly arranged to create a repelling force against each other between the stand magnetic blocks and the magnetic paper towel holder. Therefore, the magnetic paper towel holder floats in air when it is placed on top and in the middle of the magnetic stand.

A highlight ink marker comprises an inner ink tube, an outer support tube, an automatic magnetic closure apparatus, a washer, a dumbbell-shaped spring coil and an olive-shaped spring ring. The automatic magnetic closure apparatus comprises of a magnet having a central canal to allow the passage of the small ink wick tube of the inner ink tube and a nonmetal block having a bottom hole and a concave hollow to contain a metal ball. The olive-shaped spring ring is installed in two slots of the top outer tube of the outer support tube to catch the top step of the inner ink tube to keep the marker open. The dumbbell-shaped spring coil surrounds the small ink wick tube and is placed in between the washer and the bottom step of the inner ink tube to push the inner ink tube outward.
