Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Shoulder dystocia is an obstetric emergency. It is unpredictable and can occur with a large baby or a small baby. There are several maneuvers that can be applied to help prevent injury to the brachial plexus. But injury to the brachial plexus can still occur. A baby shoulder vacuum cup with a vacuum tube has a non-circular-shaped, preferably elongated or oval-shaped, bottom opening to fit onto the baby's shoulder to pull down or rotate the baby's shoulder instead of forcibly pulling on the baby's head to prevent injury to the brachial plexus. Various types of handles can be attached to the baby shoulder vacuum cup.

Abstract: 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.
