TL;DR: In this article, the activation and deactivation of an outdoors, hose faucet-mounted valve unit to control the flow of water through a standard garden hose with attached sprinkler is remotely controlled from indoors rather than at the valve unit.
Abstract: The activation and deactivation of an outdoors, hose faucet-mounted valve unit to control the flow of water through a standard garden hose with attached sprinkler is remotely controlled from indoors rather than at the valve unit. This is accomplished without the use of unwieldy and unsightly electrical cables by means of radio frequency (RF) signals. A remote, programmable, controller unit located indoors with attached transmitting unit commands such transmitting unit to send signals in accordance with preprogrammed instructions in the controller unit. A receiver unit attached to the valve unit intercepts the transmitted signals and instructs the valve unit to open or close the water valve and flow of water based thereon. Direct connection of the controller to the valve unit is possible such that the transmitter unit and receiver unit are not used such as during pleasant weather conditions. A hand held transmitter unit can be used in place of the separate controller and transmitter to automatically control the valve unit for specific watering durations.

TL;DR: In this paper, a smart water timer which includes a water timer, a receiving unit connected to the water timer and a moisture sensing unit which is in wireless communication with the receiving unit can sense when the moisture level in the soil is too moist.
Abstract: A smart water timer which includes a water timer, a receiving unit connected to the water timer, and a moisture sensing unit which is in wireless communication with the receiving unit. The smart water timer can sense when the moisture level in the soil is too moist (based on a user setting) and turn off a water supply to a sprinkler as a result A soil moisture sensing unit is placed in the soil in the area to be watered. The soil moisture sensing unit uses a moisture sensing probe and wirelessly transmits a data signal to the receiver, which is connected to the water timer, indicating whether or not the water timer should be permitted to open a water valve.

TL;DR: In this paper, a timer for monitoring the use of hot water in the home to conserve energy is shown, which is ideally suited for use as the hot water control knob of a bathroom shower.
Abstract: A timer for monitoring the use of hot water in the home to conserve energy is shown. The entire timer apparatus is enclosed inside the hot water control knob so that when the control knob is rotated to turn ON the hot water, the timer is activated. After predetermined time intervals, various visual and audio alarms are given, the alarms thus encouraging the conservation of energy by using less hot water. Also, the timer monitors the number of times the hot water has been used during a given period of time, such as a month or year. The timer, in addition to its primary energy saving function, is ideally suited for use as the hot water control knob of a bathroom shower.

TL;DR: A water timer user interface has display areas for display of water timer status information, including watering zone and watering duration indicators, user input areas, and a touch-sensitive screen as mentioned in this paper.
Abstract: A water timer user interface has display areas for display of water timer status information, including watering zone and watering duration indicators, user input areas, and a touch-sensitive screen. At least one of the display areas may display a graphical representation of the watering duration indicators for the watering zone identifiers. All of the display and input areas may be single-function areas and may be simultaneously visible to and accessible by a user. The display areas may simultaneously display both graphical and numeric representations of the watering duration indicators. An ambient temperature sensor may be used to sense the ambient temperature and humidity and provide corresponding signals to the controller to permit the controller to modify the amount of water supplied.

TL;DR: In this article, a multiple outlet water timer with an inlet and a plurality of outlets each having its own control valve is presented, operated by a clock mechanism with a cam on the clockwork mechanism case, a cam follower for each valve and each cam follower individually adjustable so that the flow of water through each outlet is adjustable independently of the other outlets.
Abstract: A multiple outlet water timer having an inlet and a plurality of outlets each having its respective control valve. The timer is operated by a clockwork mechanism with a cam on the clockwork mechanism case, a cam follower for each valve and each cam follower is individually adjustable so that the flow of water through each outlet is adjustable independently of the other outlets.
