  • Publication number: 20110284658
    Abstract: Improvements in a sprinkler head where the sprinkler head can deliver a single stream of water droplets in a three dimensional direction and then precipitate equally onto any selected terrain area which minimally scatters the water droplets. The solid stream nozzle can shoot the water stream in a preset partial arc as well as 360 degrees while the sprinkler head rotates in a horizontal circular direction to cover an equal precipitation on an entire irrigation area. The 3D Rotor consists of the vertically swivel turret which is moved vertically to change the trajectory angle by the rotating cam integrated with the turbine and reduction gear. The solid stream nozzle can deliver the water stream in a radial direction range which is changed by the angle of the trajectory which is then changed by the rotating cam containing a calculated curve.

  • Patent number: 8011602
    Abstract: Many areas watered by prior art oscillating sprinklers are substantially rectangular. However, prior art oscillating sprinklers typically produce generally or substantially elliptical water distribution patterns. This geometric incompatibility causes problems and inefficiencies. Embodiments of the current invention include an oscillating sprinkler that automatically produces a substantially rectangular water distribution pattern. The substantially rectangular water distribution pattern may be produced by automatically controlling the distance from the sprinkler that streams of water travel before impacting the ground. This is accomplished by automatically and sequentially opening and closing and/or restricting flow to select nozzles at select points and within select portions of the oscillation cycle. A current invention oscillating sprinkler may reduce waste water, may reduce run-off waste water, and may automatically provide water to the corner areas of typical substantially rectangular areas to be watered.

A data transmitting subsystem for forwarding data generated by the direct and indirect sensing means to computing means and for transmitting instructions from the computing means via interfacing means (controllers) to various devices (field effectors) in the agricultural area to perform various functions;3. A computing subsystem linked by way of said data transmitting subsystem to said indirect and direct sensing means in a pattern of many feedback loops.
