Abstract: An aerosol delivery system that includes an aerosol generator that aerosolizes a fluid for delivery to a patient as a patient inhales. The aerosol delivery system includes a pump coupled to the aerosol generator that pumps the fluid to the aerosol generator, and a breath sensor that emits a signal as the patient breathes. A controller couples to the aerosol generator, the pump, and the breath sensor. In operation, the controller receives the signal from the breath sensor, controls a flow of fluid to the aerosol generator in response to the signal, and controls the aerosol generator to start aerosolizing the fluid before the patient inhales.

Abstract: A cooperating shelf and bracket system having a bracket which embraces and engages the rear portion of the shelf so as to support the shelf and permit its mounting in cantilever fashion from a shelf upright. The bracket may be formed with arms which grip cooperating structure on the shelf so that when fully inserted the shelf is securely retained in the bracket. The shelf is easily removable via a releasing system, which permits the shelf to be inserted and removed in a horizontal plane without the need for rotation relative to the bracket.

Abstract: A shelf assembly for use with a gondola display structure comprises a bracket assembly selectively engageable with the vertically spaced slots of the gondola upright and securable at one of a plurality of selected angular orientations relative thereto. A merchandise supporting surface is slidably coupled to the bracket assembly and is slidable into a plurality of positions relative to the forward facing surface of the gondola to compensate for the effect that changes in the angular orientation have on the appearance of the merchandise supported thereon. Transversely slidable dividing members are provided to accommodate, for example, items of different width on a single shelf.
