Abstract: A long throw Pop-Up Irrigation Nozzle assembly has no oscillating or rotating parts and includes a cylindrical body having a fluid inlet and a sidewall defining at least one fluidic circuit configured to generate a selected spray pattern when irrigation fluid flows through the body. In order to throw long distance, droplet velocity, droplet size and droplet initial aim angle determine the throw to provide a low precipitation rate (“PR”) for fluidic sprays. The nozzle assembly and method of the present invention achieve a PR of 1 in/hr or less and good spray distribution with a scheduling coefficient (“SC”) of about 1.5 without utilizing any moving components to provide a significantly more cost effective nozzle assembly, as compared to prior art rotator nozzles.

Abstract: An external lens washing system has an aiming fixture configured to support and constrain an external lens which is exposed to the elements and apt to become soiled with debris. A nozzle assembly is configured to be supported and aimed toward the external lens by the aiming fixture and has at least one laterally offset washing nozzle projecting from the aiming fixture to a spray washing fluid toward the external lens surface, spraying at a shallow, glancing spray aiming angle to impinge upon and wash the lens external surface. Optionally, an integrated image sensor and lens washing assembly is configured for use with a remote control method for cleaning an exterior objective lens surface and includes a sealed image sensor housing assembly including an integral, remotely controllable lens cleaning system with an optimized configuration for aiming one or more cleansing sprays from one or more laterally offset fluidic oscillators.
