Patent ID: 11385865

Abstract:
An apparatus generates truly random numbers. The apparatus includes a container that is at least partially filled with a fluid (e.g., water or air). The apparatus also includes objects (e.g., dice) suspended freely in the fluid. The apparatus includes agitators configured to agitate the fluid, and cameras configured to capture images of the objects. When the agitators agitate the fluid, the objects move freely (e.g., move with the created currents) in the fluid in the container. The apparatus also includes a random number generation circuit coupled to the cameras. The random number generation circuit is configured to generate random numbers based on the images captured by the cameras. In some embodiments, the agitators are one or more motor-driven propellers that stir the fluid. Some embodiments use a hydraulic pump to agitate the fluid (e.g., circulating the fluid using both a push action and a pull action).
