Publication number: 20230284600Abstract: There is provided a smart aquaculture grow out system for aquatic species, the system includes a feeder adapted to store aquafeed, the feeder comprising a feed dispensing nozzle, a feed dispenser operable to measure and project aquafeed via the feed dispensing nozzle, and a controller operatively being operable to selectively activate and deactivate the feed dispenser. A set of sensors are operable to acquire sensor data comprising water quality parameters of a pond adjacent to the feeder and images of aquatic species in the pond. A processor receives the sensor data of the grow out system, and determines, based on the sensor data of the grow out system, a metered quantity of aquafeed to provide. The processor transmits a control signal to the controller causing activation of the feed dispenser to measure and project the metered quantity of aquafeed via the feed dispensing nozzle.Type: ApplicationFiled: August 5, 2020Publication date: September 14, 2023Inventors: My T Nguyen, Toan Q.

Patent number: 10245607Abstract: A fluid dispensing system includes a pump, a valve, and a dispenser disposed downstream of the valve and connected to the valve with a hose. To provide a steady flow rate at the dispenser, the pump charges the fluid to or above the pressure required to achieve a desired flow rate. The valve cycles between open and closed at a fixed frequency. The valve-open time is varied within that frequency to maintain the desired flow rate.Type: GrantFiled: March 19, 2015Date of Patent: April 2, 2019Assignee: Graco Minnesota Inc.Inventors: Jonathan R.
