    • An irrigation controller for selectively turning on and off a set of sprinkler valve stations. The irrigation controller is programmable by a user. The irrigation controller includes an irrigation control processor. The irrigation control processor includes an input port, an output port, a memory element for storing an irrigation control program and irrigation control parameters, the irrigation control program implementing a plurality of functionalities that are selectively enabled, a processing unit for executing the irrigation control program, and a bus connecting said processing unit to said memory element and to said input and output ports. An input device is interfaced with the input port. The output port is provided with interface with the sprinkler valve stations for controlling the turning on and off of the sprinkler valve stations. The input device cooperates with the control program to enable at least one specific functionality from the functionalities in response to a predetermined input being received from the user through the input device.

    • A clustered computer system includes multiple computer systems (or nodes) on a network that can become members of a group to work on a particular task, referred to herein as a protocol. A protocol is defined so that each phase of the protocol is terminated with an acknowledge (ACK) round. Within each phase of the protocol, a node cannot both send and receive a data message. The protocol includes an ACK round that provides a relative time event that indicates when a data message should be received. If the data message is not received when the ACK round occurs, the receiver knows that the sender did not send it, and can request that the sender re-send the missing data message. In a first embodiment, referred to herein as the “post-ACK” case, the receipt of expected data messages is checked after the ACK round occurs. In a second embodiment, referred to herein as the “pre-ACK” case, the receipt of expected data messages is checked before the ACK round occurs. In both cases, when the receiver sees the ACK round, it knows that the sender sent the data message. If the data message was not received by the receiver, it knows to request that the sender re-send the data message. In this manner the preferred embodiments provide an architected way for sending and receiving data messages without using timers in a clustered computing environment that includes ordered messages. As a result, the preferred embodiments may be readily implemented on computer clusters that include nodes on a wide area network (WAN) that have a large variability in their response times.
    • 集群计算机系统包括网络上的多个计算机系统(或节点),其可以成为在特定任务上工作的组的成员,这里称为协议。 定义协议,使得协议的每个阶段都以确认(ACK)轮回终止。 在协议的每个阶段中,节点不能同时发送和接收数据消息。 该协议包括ACK循环,其提供指示何时应该接收数据消息的相对时间事件。 如果在发送ACK轮回时没有收到数据消息,则接收方知道发送方没有发送,并且可以请求发送方重新发送丢失的数据消息。 在第一实施例中,这里称为“后ACK”情况,在ACK发生之后检查预期数据消息的接收。 在本文中称为“预ACK”情况的第二实施例中,在ACK轮发生之前检查预期数据消息的接收。 在这两种情况下,当接收者看到ACK回合时,它知道发送方发送了数据消息。 如果数据消息没有被接收器接收到,则知道请求发送方重新发送数据消息。 以这种方式,优选实施例提供了用于发送和接收数据消息的架构方式,而不使用包括有序消息的集群计算环境中的定时器。 结果,优选实施例可以容易地在包括在其响应时间具有大的可变性的广域网(WAN)上的节点的计算机集群上实现。

    • A heat pump circuit is installed into the inner cavity of a chimney venting the combustion gases of a burner servicing a dwelling with the exterior heat pump coil mounted in an annular gap formed around the upper chimney end. A fan driven by the chimney draft augmented by the burner then rotates an exterior rank of blade segments above the annular space to draw ambient air across the exterior coil. A set of gated apertures in the chimney wall both above and below the flue damper then directs zoned airflows up into the chimney and across the inner coil that is deployed at, the lower, interior chimney opening with the air heated in a chamber surrounding the burner either selectively routed into the chimney to further increase the chimney draft or routed into the dwelling for warmth.
