Abstract: A showerhead system includes an arm structure adapted to couple to a water pipe to receive water flow therefrom. The arm structure includes a first fluid conduit, a second fluid conduit, and a mode selector operatively coupled to the first fluid conduit and the second fluid conduit. The mode selector transitions between a first setting to direct water flow from a first chamber to a second chamber positioned below the first chamber and a second setting to direct water flow from the first chamber to a third chamber positioned below the first chamber. The second chamber is in fluid communication with the first fluid conduit and the third chamber is in fluid communication with the second fluid conduit. The showerhead system further includes a spray head configured to distribute the water from at least one of the first and second the fluid conduits.

Abstract: A vessel for use in rinsing a user's nasal cavities includes a main body, a spout extending from the main body, a nozzle attached to the spout, and a handle forming an aperture in communication with the main body. The aperture is sealable by a user to control a flow of a fluid held in the main body out of the nozzle. The nozzle defines an outer skirt deflectable upon engagement with the walls of the user's nasal cavity. A lid is removably engageable with the main body, provides fluid ingress when removed, and creates a watertight seal between the lid and the main body when engaged with the main body. An annular raised periphery may surround the aperture for facilitating sealing of the aperture with the user's finger.

Abstract: A dental water jet apparatus for adjusting a pressurized water stream from a pump to a tip moves pressurized water from a reservoir to a tip in fluid communication with the pump. A flow control knob may be turned to selectively adjust the water pressure supplied by the tip between a minimum and a maximum value. When the flow control knob is turned in a first direction, the volume of fluid directed towards the tip decreases and the volume of fluid returned to an inlet of the pump increases. Fluid may flow from the reservoir and ultimately into the tip to provide oral irrigation and/or cleaning of the teeth, gums, and tongue.

Abstract: A method and system for presenting a document to a plurality of media device types optimized for the display medium. A document is generated in a markup language, and a plurality of style sheets are provided for formatting the document for a requesting device, with each style sheet accommodating a distinct display environment. The markup elements that reference two separate cascading style sheets (CSS) are configured differently such that they isolate the CSS reference for either high-resolution graphical display devices or small screen, low-resolution graphical display devices. A third style sheet is used as an intermediary to pass a CSS reference to small screen browsers while at the same time, shielding the CSS reference from certain high resolution browsers incapable of parsing the syntax of the reference.
