US 2021/0065592 A1 · VISUAL DISPLAY DEVICE WITH BEAD TRANSPORT CONTROL

Abstract

A visual display device creating various visual and audible effects from the motion of light particulate matter, such as beads of expanded polystyrene, comprising a chamber through which a stream of air flow is configured to agitate, fluidize, suspend, or float at least some of the beads. The device also includes a bead transport control subsystem to control the flow of some beads through a conduit from one region of a chamber in the device to another different region in the chamber of the visual display device. The bead transport control subsystem comprises the conduit and a second stream of airflow into or out of a portion of the conduit through a screened opening to prevent or create fluid-like flow of the beads through the conduit that is controlled at least partially independently from the first stream of airflow.

Dependent claims

A visual display device for creating various visual and audible effects from motions of a plurality of beads, the visual display device comprising:

a chamber with at least some portion of the chamber configured to provide a view of an interior of the chamber, and comprising a primary flow subsystem comprising a first stream of airflow configured to agitate, fluidize, suspend, or float at least some of said plurality of beads;
and
a bead transport control subsystem comprising a second stream of airflow controlling a flow of at least a portion of said plurality of beads through at least one conduit connecting a first region of the chamber to a second region of the chamber;
wherein said second stream of airflow is controlled at least partially independently from said first stream of airflow.
