  • System and method for monitoring and suppressing fire
    Patent number: 11257341
    Abstract: A fire detection and suppression system includes a system controller for determining an initial location of the fire based on fire location information from fire detectors, and then the system controller determines a final location of the fire based on fire location information taking into account spatial and/or angular relationships between the fire detectors and the initial location. The system controller determines a location of the fire and activates monitors to deploy suppressant based on a distance between each of the monitors and the location of the fire. The system controller controls the monitors based on how the suppressant is deployed onto the fire.

  • Clog resistant in-line vortex element irrigation emitter
    Patent number: 11116151
    Abstract: A clog resistant in-line vortex emitter and drip irrigation assembly and method uses a double-sided circuit and a series of vortex chambers of optimized dimensions to create a pressure drop with large dimensions and good clog resistance. The vortex chamber 100 also al lows for a lower exponent than traditional circuits. This gives a pressure regulating property to the no-moving-parts circuit. The vortex emitter allows for some pressure regulation without sacrificing recyclability or requiring moving parts. The vortex circuit of the present disclosure is optimized for an emitter efficiency Ef value wherein Ef=(k/Ackt)*Amin such that k is a unitless head loss coefficient, Ackt is the area of the circuit, and Amin is the minimum cross sectional area of the circuit. A higher k per a given area with larger dimensions allows for a smaller part with a lower chance of clogging.
