Some embodiments provide irrigation controllers comprising: a housing; a control unit including a first microcontroller configured to execute irrigation programs and a first set of code; and a removable plug-in device that removably mates with a portion of the irrigation controller and communicationally couples to the first microcontroller, wherein the plug-in device comprises a memory storing a second set of code to replace at least a portion of the first set of code, wherein the plug-in device is configured to re-flash at least a portion of the first set of code allowing a copy of the second set of code to overwrite at least the portion of the first set of code; wherein the first set of code comprises a bootloader that writes the copy of the second set of code over the first set of code with the exception of the bootloader that is not written over.

A water flow metering device for use as a handheld or ground-based sprinkler includes a device body having a water inlet, a water distribution head in fluid communication with the device body, and a flow pattern selector. The flow pattern selector is coupled to the water distribution head and meters the amount of water sprayed onto the surrounding area. The flow pattern selector includes indicia that provide flow rate information to an operator. A pressure control valve regulates the flow rate in accordance with the information provided by the flow pattern selector. The water flow metering device may also include a timing mechanism having a timer which closes the water supply after a set period of time. A pressure transducer or other flow rate measuring device may allow the timer to operate the device for a predetermined amount of water distribution in inches per hour.

A shower head is configured to receive a first fluid conduit and a second fluid conduit, where the shower head includes a mixer valve within a portion thereof that is configured to receive a first fluid from the first fluid conduit and a second fluid from the second fluid conduit and to output the first fluid or the second fluid or a blend the first and second fluids to a shower head outlet.

A hose tap timer is disclosed comprising structure for shutting off the hose tap timer valves when a control member is separated from or attached to a dock for a manifold member of the hose tap timer.

A method of controlling the filling with water of a household appliance after treatment including activating a wash pump to a first speed, opening a load valve and starting a time counter, closing the valve and stopping the counter, calculating a flow-rate, opening and closing the valve again based on the calculated flow-rate.

A faucet assembly including a handle that rotates about a rotational axis extending perpendicular to an angled interface for adjusting a water parameter.

In a method for operating a valve, one valve element of the valve being able to be moved from a first position into a second position by activating an electrically actuatable actuator, the actuator is activated at least once in a first time interval, and is thereafter not activated in a second time interval, and a signal characterizing a strike of the valve element at the first position is ascertained at electrical terminals of the actuator. During the process, an activation energy of the actuator is gradually modified, and a threshold value of the activation energy at which the valve element is just able or is just no longer able to lift is ascertained.

A shower head having a stem, a spray head coupled to the stem and including a plurality of outlets for discharging water into at least one spray pattern, and a mixing valve located within the stem. The mixing valve has a housing having a first inlet, a second inlet and an outlet; a first flow control valve for controlling the flow of a first fluid from the first inlet to the outlet; and a second flow control valve for controlling the flow of a second fluid from the second inlet to the outlet. The shower head also has a touchscreen user interface located on a surface of the shower head, wherein the touchscreen user interface allows a user to control at least one of a temperature or a flow rate of fluid from the outlet to the spray head by controlling the first and second flow control valves.

A gas management assembly for a substrate processing apparatus includes: an exhaust module including a basic exhaust line that is formed to exhaust a chamber gas containing a process gas supplied to a chamber of the substrate processing apparatus to a discharge system; a recovery connection module including a recovery exhaust line that is branched from the basic exhaust line and formed to exhaust the chamber gas to a recovery system; and a control module configured to perform automatic switching of an exhaust path of the chamber gas from one of the basic exhaust line and the recovery exhaust line to the other based on at least one of an operation mode of the substrate processing apparatus, a pressure of the chamber, or a pressure of the recovery exhaust line.
