Embodiments herein include void-free material depositions on a substrate (e.g., in a void-free trench-filled (VFTF) component). In some embodiments, a method may include providing a plurality of device structures extending from a base, each of the plurality of device structures including a first sidewall opposite a second sidewall and a top surface extending between the first and second sidewalls, and providing a seed layer over the plurality of device structures. The method may further include forming a dielectric layer along just the top surface and along an upper portion of the first and second sidewalls using an angled deposition delivered to the plurality of device structures at a non-zero angle of inclination relative to a perpendicular extending from an upper surface of the base, and forming a fill material within one or more trenches defined by the plurality of device structures.

Devices, systems and methods are described for launching a projectile. Preferred devices comprise two separate platforms that are connected by an elastic cable. Each of the platforms can be secured to one foot or shoe of a user by a strap or other fastener. Once secured, a force can be applied to a projectile that is connected to the elastic cable to thereby stretch the cable in a first direction. Once the force is removed, at least some of the elastic force of the cable can be transferred to the projectile causing the projectile to be propelled in a direction opposite to the first direction.

A device for launching a projectile along an intended flight trajectory includes a launching mechanism. The launching mechanism includes supports supporting a launching cord. A projectile having a longitudinal axis is disposed in the launching cord in a launch position prior to launch such that the projectile's longitudinal axis is perpendicular to a plane in which the launching cord is disposed. As the projectile is launched by the launching mechanism, the projectile rotates such that the projectile's longitudinal axis is parallel to the plane in which the launching cord was disposed.

An improved slingshot band having a tapered outer contour. The slingshot band has a tubular body having a first fork end and a second pouch end. The tubular body comprises a first layer of an elastic polymer. The first layer has a constant thickness. The tubular body further comprises a second layer of an elastic polymer. The second layer has a greater thickness near the fork end of the tubular body and lower thickness near the pouch end of the tubular body. The increased thickness of the section of the tubular body near the fork end of the slingshot band reinforces the most vulnerable section of the slingshot band against failure, thereby extending its longevity.

The invention relates to an archery system that launches an arrow from a position that is perpendicular to a direction of flight for the arrow. After release, the arrow rotates to a position that is parallel to the direction of flight to the target.

Described herein is a portable outdoor water and snow activity station used as a game or a toy. The activity station is a mesh screen panel PVC structure with supports that has a detachable water hose, which connects to a standard water spigot; the detachable hose has on/off nozzles for filling water balloons and other water toys and may be removed during non-use. The activity station has multiple slingshot launchers that may be used for launching both water balloons and snowballs. The activity station's adjoined mesh screen panels shield players as they propel objects with the slingshot launchers. The activity station contains rear storage pouches to hold water balloons and snowballs while in use. The activity station's foldable design allows for easy set up, take down, portability, and storage. The object of the game is for players at opposing stations to launch water balloons and snowballs at each other.
