Abstract: A system and method for a procedure that can be performed on an appropriate subject. A procedure may be planned, at least in part, prior to performing the procedure. An image may illustrate at least a portion of the planned procedure for confirmation and/or alteration of the planned procedure prior to performing the procedure.

Abstract: A sonic projector system is disclosed. The sonic projector system includes: a left speaker cabinet system having a left sound projection component configured to project sound; a right speaker cabinet system having a right sound projection component configured to project sound; and a screen configured to receive the projected sound from the left speaker cabinet system and the projected sound from the right speaker cabinet system, where the screen includes a middle portion that receives and transforms the projected sound from the left speaker cabinet system and the projected sound from the right speaker cabinet system to a combined projected sound, where the screen is configured to distribute the combined projected sound to a specific area.

Abstract: In an active magnetic regenerator apparatus having a regenerator bed of material exhibiting the magnetocaloric effect, flow of heat transfer fluid through the bed is unbalanced, so that more fluid flows through the bed from the hot side of the bed to the cold side than from the cold side to the hot side. The excess heat transfer fluid is diverted back to the hot side of the bed. The diverted fluid may be passed through a heat exchanger to draw heat from a fluid to be cooled. The apparatus may be operated at cryogenic temperatures, and the heat transfer fluid may be helium gas and the fluid to be cooled may be hydrogen gas, which is liquified by the device. The apparatus can be formed in multiple stages to allow a greater span of cooling temperatures than a single stage, and each stage may be comprised of two bed parts.

Abstract: The rotary dipole active magnetic regenerative refrigerator (10) of the present invention comprises a stationary first regenerative magnetic bed (12) positioned within a stationary first inner dipole magnet (14), a stationary second regenerative magnetic material bed (16) positioned within a stationary second inner dipole magnet (18), an outer dipole magnet (20) that rotates on a longitudinal axis and encloses the inner dipole magnets (14, 18), a cold heat exchanger (22), hot heat exchangers (24, 26), a fluid displacer (28), and connective plumbing through which a heat transfer fluid is conveyed.

Abstract: An audio speaker system designed to achieve multidirectional sound characteristics which includes an enclosure body having a base, front wall, two angled, forward sound directing side walls, at least one angled, inclined rear wall and a top wall which slopes downward from the rear wall to the front wall. At least one acoustic speaker is affixed to the top wall and to each of the front, side and rear walls of the enclosure body.
