1. A sprinkler for watering a selected surface of a land parcel having a selected size and shape, said apparatus comprising:
- a sprinkler base, said sprinkler base comprising a lower housing defined by a sprinkler base inner side wall, said sprinkler base comprising an inlet for receiving a pressurized water flow, an inlet turbine operably fixed in the base, a gear train having an output gear responsive to the inlet turbine;
an upper housing, said upper housing rotatably coupled to said sprinkler base, said upper housing driven by said output gear, said upper housing configured for receiving water from said base, said upper housing further comprising at least one sprinkler nozzle assembly, said at least one sprinkler nozzle assembly secured to and rotatable with the upper housing, the sprinkler nozzle assembly comprising a nozzle, a solenoid valve, and an outlet nozzle; and
a set of discontinuous slip ring contacts, said set of discontinuous slip ring contacts including a ground ring and powered segments, said powered segments connected with a low voltage power source for energizing said solenoid valve, wherein during rotation of said upper housing, said discontinuous slip ring contacts turn said solenoid valve on when adjacent said powered segments, and off when not adjacent powered segments, to thereby control output of water from said nozzle.

Abstract
A sprinkler. A stationary base includes a turbine to drive an upper housing. A plurality of sprinkler nozzle assemblies mounted on the upper housing include low voltage solenoids that are energized via slip ring contacts, with a power discontinuous slip ring located on the base. When powered, the solenoids open to allow water to be directed from the nozzle in the sprinkler nozzle assembly. the nozzles are sized, shaped, and directed to apportion water as needed to provide average water quantities amongst parts of irregularly shaped parcels.
