A paving system includes a paving machine, a controller, and a control panel. The paving machine includes a machine frame, a drive assembly, and a paving material delivery assembly, which includes a hopper, a conveyor assembly, an auger, and a screed. The paving machine also includes an emulsion fluid delivery assembly, including a tank of emulsion fluid and a spray bar including a plurality of nozzles. The controller is wired or wirelessly coupled to the tank and the spray bar to control at least one of a temperature, pressure, or delivery rate of the emulsion fluid through the nozzles.

A method and device for indicating whether a dispensable product will require refilling prior to the next scheduled service interval includes tracking the amount of use over a first interval, and calculating a frequency based from the use over the first interval. The quantity remaining is compared with the required amount, which is the product of the number of weeks in the service interval and the calculated frequency. Thus, when the quantity remaining is less that the required amount, a warning will be provided to indicate that the dispensing product should be replaced, as it will be empty before the next service interval.

A dispensing apparatus in which product is dispensed by moving, preferably by manually applied forces from a user, an actuation mechanism, preferably a lever, from a first position to a second position and in which a potentiometer sensor, preferably a rotary potentiometer sensor, senses the relative movement of the actuation mechanism with time and permits the amount of fluid dispensed to be accurately calculated.

Embodiments of a sprayer system having spray nozzles; each nozzle includes a thermistor or resistor that provides an electronic current or voltage value correlated with a flow rate or a local temperature. A low flow rate indicates of a fluid flow clog or plug within the nozzle or conduit. The flow rate or temperature results among the different nozzles are compared to detect which nozzles are partially or entirely clogged or otherwise anomalous. In various embodiments, the thermistor electronics are integrated in each individual nozzle. In some embodiments, upon detection of a potential clog, the electronics create an alert and respond to the clogged condition.

An automatic HVLP paint spray gun utilizes turbine air atomizing the paint as it is discharged from a central nozzle, as well as for fanning the paint. The turbine air for fanning or the fanning turbine is directed at the paint after it issues through a paint discharge port disposed centrally of the gun. The utilization of turbine air for both atomizing and fanning provides a paint spray gun which operates between psi up to about 10 psi.

A drain clearing air gun includes a housing defining a main body, a handle positioned on a first end of the main body, and a nose positioned on a second end of the main body. A tank is at least partially positioned within the housing and includes a chamber for receiving pressurized air. A motor is positioned within a main body of the housing, and a pump is positioned within the main body of the housing and operatively coupled to the motor. The pump is driven by the motor to pump air into the tank. A pressure gauge is supported by the housing and includes an automatic shutoff feature. The pressure gauge is in fluid communication with the tank. When a predetermined pressure within the tank is reached the automatic shutoff feature is activated to stop the motor.

A system for growing plants, the system may include a substrate having one or more weakened areas or openings: one or more grow portions coupled to the substrate and situated at the one or more weakened areas or openings and having at least one seed or plant; and/or a fluid distribution portion coupled to the substrate and configured to provide fluid to the one or more grow portions. The system may further include a method of operation including one or more acts of: obtaining a weather forecast for a future time period; determining whether rain is expected during the future time period; and preventing, terminating, or restricting an irrigation cycle when it is determined that rain is expected during the fare time period. The restricting may restrict a flow of liquid during the irrigation cycle or shorten the irrigation interval.

A paint sprayer including a base and a plurality of components mounted on the base, including a gun mounted on the base, a head mounted on the gun and a nozzle mounted on the head, wherein the paint sprayer further includes at least one sensor.

A fluid delivery system includes a status indicator and control system comprising a processor. The processor is configured to receive a first signal indicative of a first status of operations of a spray application system. The processor is further configured to provide to an operator of a spray gun, via a display system, a visualization representative of the first status of operations, and techniques to control the fluid delivery system, wherein the spray application system is configured to deliver at least one fluid to the spray gun during operations.

Systems and methods can control a pumping system. Operating characteristics of a driving apparatus are obtained. The driving apparatus is operatively coupled to a pump and operates to effect operation of the pump. Additionally, instructions are provided to an electronic speed controller. In particular, the instructions direct the electronic speed controller to control activity of the driving apparatus.
