Abstract: A headrest support rod includes a first hollow tubular portion and a second hollow tubular portion. The first hollow tubular portion includes a first end having a first opening configured to receive filler material from an injection pump, is configured to support a headrest, and is configured to be disposed at least partially outside of the headrest. The second hollow tubular portion includes an opening and is configured to be disposed at least partially inside the headrest. The first hollow tubular portion is configured to enable the filler material to be transmitted from the first opening to the second hollow tubular portion, and the second hollow tubular portion is configured so as to enable the filler material to pass through the second opening to form the headrest.

Abstract: Preferred aspects of this invention relate to surface irrigation methods, systems and kits for irrigating a ground surface. In particular, these irrigation methods and systems are designed to conserve water and reduce run-off. Embodiments of the irrigation systems comprise a pipe and an emitter assembly, which comprises a sealing adapter, an emitter tube and a pressure compensating flow emitter. In preferred embodiments, such irrigation systems further comprise a controller adapted to transmit and receive data, including weather data, from a remote transceiver and adjust irrigation parameters for the system based on the data.
