Abstract: Embodiments of the invention provide wireless irrigation control systems and related methods. In one embodiment, the invention may be characterized as a wireless irrigation control system comprising: at least one water flow control device; a watertight housing; and a wireless receiver within the watertight housing and adapted to receive irrigation schedule related signals. The system also includes a memory within the watertight housing and adapted to store an irrigation schedule established or modified by the received irrigation schedule related signals; and a controller within the watertight housing and coupled to the memory, the controller adapted to execute the irrigation schedule to cause the water flow control device to operate according to the irrigation schedule. Additionally, a power supply is within the watertight housing and adapted to supply power to at least the controller.

Abstract: An irrigation control device has a controller sealed within a watertight housing. The control device also has an antenna, power supply and battery charging device, such as a solar array. The controller receives signals through the antenna and updates one or more watering schedules stored in a memory module, based on the received signals, and generates control signals to execute a watering schedule. The battery charging device recharges the power supply and the irrigation control device requires no external electrical connections for power or control. Control signals are generated in a central controller remote from the rotor, and are preferably transmitted to the rotor antenna through a commercial paging or other type of public broadcast network.

Abstract: An embodiment may comprise a system for controlling NOx emissions from a turbine having combustion chambers. The system may comprise a center fuel flow and a plurality of outer fuel flows for each of a plurality of combustion chambers. An outer fuel flow is set to achieve a desired level of combustion dynamics for at least one of the plurality of combustion chambers. A delta adjustment value is determined for the center fuel flow that will result in a desired level of NOx emissions from the turbine, and for adjusting the center fuel flow according to the determined delta adjustment value to obtain the desired level of NOx emissions from the turbine.
