  • Patent number: 10285343
    Abstract: A center pivot irrigation system is described that includes a controller that makes use of a particular flow rate of input water to deliver a consistent depth of irrigation to user-defined areas under a pivot irrigator. The controller operates to pulse control valves for the nozzles/sprinkler heads on and off as the sprinkler arm rotates. The valve pattern along the span of the sprinkler arm is chosen during each operating cycle such that the total water flow through all the open valves matches the flow rate of the input or supply water to the pivot irrigator. To ensure a consistent depth, the speed is changed during valve duty cycles to match the density of open valves in the sprinkler arm. To ensure a consistent distribution under the sprinkler arm, each valve is monitored to ensure that the valves are given the same proportional share of the input water.

  • Patent number: 10286239
    Abstract: A fire-fighting vehicle includes a boom assembly movably coupled to a chassis, a penetrating nozzle coupled to the boom assembly, an actuator that moves the penetrating nozzle relative to the chassis, and a controller operatively coupled to a sensor. The penetrating nozzle includes a piercing tip and an outlet configured to be selectively fluidly coupled to a supply of fire suppressant. The piercing tip is repositionable between a first position spaced from a surface of an object and a second position within an interior cavity of the object. The outlet supplies fire suppressant into the interior cavity when the piercing tip is in the second position. The sensor provides data relating to at least one of a position and an orientation of the piercing tip relative to the surface. The controller determines an angular orientation of the piercing tip relative to the surface based on the data.

  • Patent number: 10099238
    Abstract: This invention concerns a method and apparatus for dispensing minute quantities of fluids and more particularly rapidly dispensing highly precise and repeatable, minute amounts of viscous fluids in a non-contact manner. An impacting element is impacted against a hardened insert on a flexible diaphragm to deflect the insert into a jetting chamber and against an outlet orifice in the jetting chamber. The movement of the diaphragm and insert force viscous fluid in the chamber through the outlet orifice and the impact jets that fluid from the outlet orifice, with the impact force being adjusted to jet the fluid from the orifice in a single drop.
