Abstract: A head-restraint system includes a rotatable base portion; a stationary platform positioned underneath the base portion, wherein the platform supports the base portion; a rotatable head cradle positioned within an open region of the base portion; a first pivoting mechanism that allows the head cradle to rotate with respect to the base portion; and a second pivoting mechanism that allows the base portion to rotate with respect to the platform.

Abstract: A method and apparatus for generating and emitting a continuous stream of bubbles formed from a supply of bubble liquid directs a first airstream into a supply of bubble liquid to create a froth of bubble liquid in a chamber, directs a second airstream against the froth in the chamber to drive the froth from the chamber through an exit chimney so that a film of the driven bubble liquid froth becomes attached to the exit chimney and the second airstream directed against the attached film creates and inflates a bubble attached to the exit chimney, and directs a third airstream peripherally about the exit chimney to facilitate detachment from the exit chimney of the created and inflated bubble attached to the exit outlet and displacement of the detached bubble away from the exit outlet. A self-contained apparatus incorporates a user-operable generator for creating a primary airstream which is redistributed to form the first, second and third airstreams.
