  • Patent number: 10101013
    Abstract: Employing capacitors as shunts in a decorative light string can prevent the circuit from being opened when a lamp burns out or becomes loose in the socket. But manually assembling such a light string is costly and the quality of the resulting string is not assured to be high. The present disclosure introduces a shunted light string, and a method of assembling that light string that is able to be automated to ensure a consistent quality level by reducing or eliminating human workmanship issues.

  • Patent number: 10016691
    Abstract: The disclosed technology includes an apparatus for a water bucket game. The water bucket game may fill a suspended container with water until the force of the water causes the container to rotate and empty onto pool-goers below. The extent of the rotation may be limited by a stopper positioned within a recess of the container. The water bucket may be configured such that the water bucket returns to an upright position after the bucket empties the water.

  • Patent number: 9631386
    Abstract: Embodiments of the present invention provide an improved pool. Embodiments of the present invention also provide a method of making an improved pool. The pool can comprise an integrated sidewall joined to a floor portion. The integrated sidewall can be constructed from one piece of material, and can have fewer seams than traditional pools, thereby reducing the likelihood that that pool will rupture and leak. In some embodiments, since the pool has fewer seams than traditional pools, fewer manufacturing steps are required to make the pool. This can increase manufacturing speed and decrease cost.
