Abstract

Several embodiments provide cycle and soak irrigation control units, comprising: a housing; a plurality of pairs of actuation line connectors comprising input connectors to couple with output actuation lines of a separate irrigation controller, and output connectors to couple with actuatable devices; a plurality of electrical pathways each coupling a respective input connector to a corresponding output connector and allowing an activation signal to be passed; at least one switch configured to selectively allow or interrupt activation signals to pass to a corresponding output connector; and a timing control circuit controlling the switch, based on an application of an activation signal on an input connector, a duration of a series of cycle-on timings during which the activation signal is emitted from the output connector to activate an actuatable device and soak-off timings during which the activation signal is prevented from being emitted deactivating the actuatable device.

First claim

What is claimed is:

1. A cycle and soak irrigation control unit, comprising:
a housing;
a plurality of pairs of actuation line connectors secured with the housing and each pair comprising an input connector and a corresponding output connector, wherein each input connector is configured to couple with at least one controller output actuation line of an irrigation controller, and wherein each output connector is configured to couple with at least one irrigation actuatable device configured to control a flow of water, wherein the irrigation controller is separate from and external to the cycle and soak irrigation control unit;
a plurality of electrical pathways within the housing, each electrical pathway coupling a respective input connector to a respective corresponding output connector and allowing an activation signal received from the irrigation controller at the respective input connector via a respective one of the output actuation lines of the irrigation controller to be passed to the respective corresponding output connector;
at least one switch configured to selectively allow or interrupt activation signals to pass from a respective input connector to a corresponding output connector; and
a timing control circuit coupled with and controlling operation of the at least one switch, wherein the timing control circuit is configured to:
detect an application of a first activation signal from the irrigation controller on the first input connector; and
control the at least one switch according to a predefined cycle and soak sequence to control, in accordance with the first activation signal received from the irrigation controller, a duration of a series of cycle-on timings during which the first activation signal is emitted from the first output connector to activate a first actuatable device and soak-off timings during which the first activation signal is prevented from being emitted from the first output connector deactivating the first actuatable device.

2. The cycle and soak control unit of claim 1 , further comprising:
a common line input connector;
a common line output connector; and
a common line electrical pathway within the housing coupling the common line input connector to the common line output connector;
wherein the at least one switch couples with the common line electrical pathway and is configured to control the activation and deactivation of the first actuatable device as dictated by the timing control circuit consistent with the series of cycle-on timings and the soak-off timings.

3. The cycle and soak control unit of claim 1 , wherein the at least one switch comprises a plurality of switches each coupled with one of the plurality of electrical pathways; and
wherein the timing control circuit comprises a plurality of timing control units each coupled with at least one of the plurality of switches and configured independently control the respective at least one of the plurality of switches.

4. The cycle and soak control unit of claim 3 , further comprising:
a plurality of independent cycle and soak modules, wherein each of the plurality of independent cycle and soak modules comprises:
one of the plurality of the pairs of actuation line connectors;
one of the plurality of timing control units; and
one of the plurality of switches activated by the corresponding timing control unit.

5. The cycle and soak control unit of claim 1 , wherein the timing control circuit draws power from the first activation signal in powering the timing control circuit and controlling the at least one switch.

6. The cycle and soak control unit of claim 1 , further comprising:
a user interface secured with the housing and comprising at least one selectable option to define the duration of at least one of the cycle-on timings and the soak-off timings.

7. The cycle and soak control unit of claim 6 , wherein the user interface comprises a display configured to display at least the defined duration of the at least one of the cycle-on timings and the soak-off timings defined in response to detecting a selection of the at least one selectable option.

8. The cycle and soak control unit of claim 6 , wherein the at least one selectable option comprises a plurality of physical buttons that are selectable by a user.

9. The cycle and soak control unit of claim 1 , further comprising a first disable option coupled with the timing control circuit and configured to disable the timing control circuit from preventing the first activation signal from be applied to the first output connector.

10. The cycle and soak control unit of claim 1 , wherein the timing control circuit is configured to detect from the irrigation controller a defined duration of the at least one of the cycle-on timings and the soak-off timings.

11. The cycle and soak control unit of claim 1 , further comprising:
a wireless transceiver coupled with the timing control circuit and configured to wirelessly receive a defined duration of the at least one of the cycle-on timings and the soak-off timings.

12. A method of implementing irrigation cycle and soak functionality, comprising:
detecting, at a first input connector of a first pair of actuation line connectors of a plurality of pairs of actuation line connectors cooperated with a housing, an application of a first activation signal from a separate and external irrigation controller, wherein the first pair of actuation line connectors comprises the first input connector and a corresponding first output connector;
accessing a first cycle-on timing and a first soak-off timing; and
repeatedly and sequentially controlling, in accordance with the first activation signal received from the irrigation controller, at least one switch according to a predefined cycle and soak sequence to control: durations consistent with the first cycle-on timing during which the first activation signal activates a separate and external first actuatable device, and durations consistent with the first soak-off timing during which the first activation signal is prevented from activating the first actuatable device.

13. The method of claim 12 , wherein the controlling the at least one switch comprises opening and closing a common line electrical pathway within the housing in controlling an activation and deactivation of the first actuatable device consistent with the first cycle-on timing and the first soak-off timing.

14. The method of claim 12 , further comprising:
independently controlling a respective one of a plurality of switches, each coupled with one of a plurality of electrical pathways within the housing and coupling a respective input connector to a respective corresponding output connector of the plurality of pairs of actuation line connectors, through a respective one of a plurality of timing control units of the timing control circuit each coupled with a respective one of the plurality of switches.

15. The method of claim 12 , further comprising:
drawing power from the first activation signal and powering the timing control circuit in controlling the at least one switch.
