Abstract: A hose having an observed color, the hose includes a tubular wall having an interior, an exterior and a thickness. The observed hose color changes between a first hose color in a first state and a second hose color in a second state. Differences between the first state and second state may be the result of different expansions of the hose, different pressure pressures within the hose, differences in amount of fluid within the hose and different tensions states for the hose. Observed color changes between the first state and second state may be a color change, a color shade change, alternating rings of at least two different colors or shades of color along the length of the hose, a color pattern change or even the generation of indicia on the hose.

Abstract: An expandable and contractible hose, the hose includes a segmented tubular wall circumscribing an interior. The segmented tubular wall is made up of a plurality of contiguous segments. Each contiguous segment expands along the length of the hose with the application of pressure from within. A bias holds the contiguous segments in a collapsed state when no pressure is applied from within the interior. A pressurized fluid passing within the interior overcomes the bias and causes the contiguous segments to expand into an expanded state.

Abstract: The patent application is directed to a moisture indicator that reversibly changes between two different colors depending on whether the moisture indicator is in a wet state or in a dry state. The moisture indicator is used to provide visual information about dryness/wetness of a substrate such as plant soil. The moisture indicator comprises a porous body member having a moisture indicating color and a moisture indicating material over the moisture indicating color. Water passed through the porous material activates the moisture indicating material from a dry opaque state to a transparent clear state. In the transparent clear state, the moisture indicating material reveals the moisture indicating color.

Abstract: A length of flexible corrugated hose of polymeric material inserted as a connector in a fluid or air-line to transmit liquids or air at a consistent flow from an intake source to an outtake receptor, while the intake and outtake ends are located at a variety of angles up to 180° to each other.
