  • Publication number: 20250146849
    Abstract: A system is disclosed to obtain irrigation water consumption data for a water-monitored property. The system may include a non-transitory computer-readable medium and computer code encoded on the non-transitory computer-readable medium, for, among other things, opening and closing each of one or more irrigation valves in accordance with calibration schedule data during a first period of time within one or more future time periods occurring at regular intervals when water consumption is not likely to occur or is likely minimal; and calculating a first computed flow rate for at least one irrigation valve of the one or more irrigation valves based on, among other things, the calibration valve open time and the calibration valve close time. A method and computer program product related to the foregoing system are also disclosed.

  • Patent number: 12292099
    Abstract: A friction drive transmission includes a drive pulley having an engaging face, a tip plate that supports the drive pulley and is configured to pivot about a pivot axis that is parallel to an axis of rotation of the engaging face of the drive pulley, and a friction ring that drives an axle. The friction ring may contact the engaging face of the drive pulley and may be moveable relative to the engaging face of the drive pulley to transition between forward rotation and reverse rotation. When the friction ring moves into a reverse rotation position for reverse rotation of the axle, the tip plate may pivot, with the drive pulley, about the pivot axis from a first position into a second position. The first position may be different from the second position.
