Abstract: A light sphere display device is disclosed that provides a persistence of vision (POV) light field display. The device is preferably globe-shaped and has a transparent outer globe with an outer surface having touch-sensitive capability that enables user interaction and control of the device. In embodiments, the device provides a 360 degree POV display as seen on the outer surface, by rotating a support bar having an attached circuit board including LEDs about one or more axes of rotation within the device. The device can be held in the hands of a user, or placed upon one or more gaming accessories such as gaming guns, presentation bases, and action figures. The device communicates with the accessories to provide augmented virtual reality displays of the accessories and to provide interactive gaming displays, in examples. The device also displays images and receives interactive games sent over wireless connections from cell phones.

Abstract: A tile leveling system for leveling tiles is disclosed. The system has a tile lifter whose transverse member is inserted into the grout gap, and turned to get underneath adjacent tiles. The system has a reusable clamping unit, a U-shaped, possibly flexible, wedge, which is slid through the lifter's vertical shaft to sandwich the tiles between the transverse member and the wedge. The transverse member can be concave up, and the lifter can have two transverse members with spacers on each four-corner junction. The lifter's handle can have a U-shaped hole, which allows a rocker tool to be used to level tiles. Another leveling tool, called a gun tool can be used with any of the lifters. Also proposed are two simpler threaded and zip-tie systems. The leveling devices can be used as needed, thus saving the cost of using them in the entire tiled area.
