Abstract: Power generation devices and methods for use with toilets is disclosed. A number of power generation devices are provided that can be used in combination to power various features in a toilet which will be particularly useful for portable toilets that are off the grid. The power generation devices and methods include, for example, using a cell battery inside a toilet water source, a wind turbine, solar panels, and piezoelectricity. The features include, for example, lighting up the toilet with light-emitting diodes (LEDs) to make it easier for users to find the toilet, an audio/video setup for entertainment, and a toilet status light indicator to let the next user know when the toilet paper is out.

Abstract: A method and apparatus to automatically calibrate one or more attributes of a gaming system. For instance, the gaming system determines, in response to analysis by a processor of image data via a machine-learning model, an orientation of an affixed (e.g., printed) fiducial marker positioned in a known location on a planar playing surface of a gaming table. The system also transforms, in response to determining the orientation, first geometric data associated with an object on the planar playing surface to isomorphically equivalent second geometric data. The system also digitally illustrates, via an augmented reality overlay of the image data using the isomorphically equivalent second geometric data, a graphical representation of the object positioned relative to the fiducial marker on the planar playing surface.

A number of power generation devices are provided that can be used in combination to power various features in a toilet which will be particularly useful for portable potties that are off the grid. The power generation devices and methods include, for example, using a cell battery inside the toilet bowl or flush tank, a wind turbine, solar panels, and piezoelectricity. The features include, for example, lighting up the toilet with light-emitting diodes (LEDs) to make it easier for users to find the toilet, an audio/video setup for entertainment, and a toilet status light indicator to let the next user know when the toilet paper is out.
