Abstract: An irrigation control system having an irrigation controller with a unique identifier and configured to execute irrigation schedules, collect, store and forward watering metrics and determine global time, together with a power source, a global time receiver in communication with the microcontroller and configured to provide time from an outside source to the microcontroller and a transceiver in communication with the microcontroller configured to send messages including its unique identifier, predefined irrigation schedules, stored watering metrics and current global time. The system further includes a mobile computer having a microprocessor, a wireless transceiver configured to receive the messages from the irrigation controller transceiver and transmit instructions to the irrigation controller via a communication link and a memory coupled to the microprocessor and configured to store predefined irrigation schedules, and watering metrics. Methods for providing watering metrics and controlling an irrigation control system or value controller are also disclosed.

Abstract: A sprinkler and side-loading nozzle insert assembly includes a sprinkler body provided with a flow passage and a nozzle insert seated in a complementary recess in said sprinkler body. The nozzle insert is rotatable to plural operating positions and it includes an elongated, substantially cylindrical insert body having an insert axis about which the nozzle insert rotates. A nozzle bore extends through the insert body on an axis transverse to the insert axis and alignable with the flow passage in one of the plural operating positions. A forward end face is provided with a turning knob and plural index tabs extending radially from the insert body at circumferentially-spaced locations proximate the forward end face. The index tabs are adapted to engage respective index notches in the sprinkler body as the insert body is rotated to the plural operating positions.

Abstract translation: 喷洒器和侧向加载喷嘴插入组件包括具有流动通道的喷洒器主体和位于所述喷洒器主体中的互补凹部中的喷嘴插件。 喷嘴插件可旋转到多个操作位置，并且其包括细长的基本上圆柱形的插入体，其具有插入轴线，喷嘴插件绕其旋转。 喷嘴孔在横向于插入件轴线的轴线上延伸穿过插入体，并在多个操作位置之一中与流动通道对准。 前端面设置有转动把手和从插入体径向延伸的多个索引片，所述索引片在靠近前端面的周向间隔开的位置处延伸。 当插入物体旋转到多个操作位置时，索引片适于接合喷洒器主体中的各个索引凹口。

Abstract: A pilot valve includes a housing, a motor secured in the housing and including a rotating output shaft, and a rocker disposed in the housing and coupled with the motor via a cam mechanism. The rocker is pivotable between a CLOSED position and an OPEN position by operation of the motor. The rocker includes a left-side boss and a right-side boss that are positioned in a path of the cam mechanism, where the left- and right-side bosses serve as cam stops in the CLOSED and OPEN positions, respectively. The housing may include features to better secure the motor, and the assembly may be configured to prevent unintended changes of state during periods of nonuse.

Abstract: A clip for holding a pair of nozzle inserts for use with an irrigation sprinkler includes at least two flexible attachment arms, each attachment arm provided with an elongated slot and a retention shoulder on an inside surface thereof, adjacent the elongated slot. Each attachment arm is adapted to be received in an opening in a respective nozzle insert and retained therein by the retention shoulder. A related tool includes a pair of gripper arms and a respective pair of jaws extending from the gripper arms, pivotally secured to one another. One jaw is formed with a pair of parallel prongs, and the other jaw is formed with a flat head projecting toward the pair of prongs. The jaws are adapted to engage the nozzle insert and disengage the retention shoulder to permit removal of the nozzle insert from the clip.

Abstract translation: 用于保持用于灌溉喷洒器的一对喷嘴插件的夹子包括至少两个柔性连接臂，每个连接臂在其内表面上设置有细长狭槽和与其相邻的细长狭槽的保持肩部。 每个连接臂适于容纳在相应的喷嘴插件中的开口中并由保持肩保持在其中。 相关的工具包括一对夹持臂和从夹持臂延伸的相应的一对夹爪，它们彼此枢转地固定。 一个钳口形成有一对平行的叉，另一个钳口形成有朝向一对尖头突出的平头。 钳口适于接合喷嘴插件并使保持肩部脱离，以允许将喷嘴插件从夹子上移除。
