    Abstract: An unmanned aerial vehicle (UAV) includes a sprayer configured to generate a pressurized fluid flow and a nozzle configured to receive the pressurized fluid from the sprayer and to generate a spray fan to apply the fluid to a surface. The UAV includes sensors and a control unit to control both flight of the UAV and spraying by the sprayer. The fluid can be stored onboard the UAV in a reservoir or can be remotely stored and pumped to the UAV. The UAV control unit can be preloaded with a spray plan and a flight plan, or the UAV can be controlled by a user.

    Abstract: A battery powered fluid sprayer includes a reciprocating positive displacement pump, a power supply that includes a battery, an electric motor, a motor controller, a user-adjustment mechanism for setting a user-adjustable pressure threshold corresponding to system fluid pressure of the battery powered fluid sprayer, a pressure switch, and a power controller. The pressure switch generates a pressure signal indicative of whether the system fluid pressure is greater than the user-adjustable pressure threshold. The power controller is configured to control power of the battery powered fluid sprayer by providing operating power of the motor controller in response to the pressure signal indicating that the system fluid pressure is less than the user-adjustable pressure threshold, and not providing the operating power of the motor controller in response to the pressure signal indicating that the system fluid pressure is greater than the user-adjustable pressure threshold.

    Abstract: A plural component dispensing system includes a first heated hose, a second heated hose, a controller, and a dispensing device. The first heated hose and the second heated hose include electrical wires that supply heat to the first and second heated hoses to heat fluid components within the first and second heated hoses. The first and second heated hoses are electrically coupled to the controller and are fluidly coupled to the dispensing device. The controller is configured to control and alternate the electrical power supplied to the first heated hose and the second heated hose to heat the first heated hose independent of the second heated hose.

    Abstract: A lubricant pump (14) and a method thereof are disclosed. The lubricant pump (14) includes a pump base (32) and a reservoir housing (30). The pump base (32) and the reservoir housing (30) define a lubricant reservoir for storing lubricant. One or more pump elements (34) extend at least partially into the lubricant reservoir. Heaters (36) are disposed on the pump base (32) proximate the pump elements (34). The heaters (36) are configured to heat the local area surrounding the pump elements (34), to thereby reduce the viscosity of the lubricant at the pump elements (34). The heaters (36) are electrically connected to a thermal switch (38) to control activation and deactivation of the heaters (36). With the lubricant pump (14) and the method thereof, the thermal switch (38) can control the heater (36) based on air temperature rather than the temperature of the lubricant, so the viscosity of lubricant is well controlled.
