Monitoring systems for center pivot irrigation systems and methods of irrigating an agricultural crop using the irrigation systems are provided. The irrigation systems may comprise a plurality of in-canopy sprinklers. The monitoring systems are configured to detect an operational condition of the plurality of in-canopy sprinklers, including whether individual sprinkler heads have become detached from the irrigation system main line, or whether an individual sprinkler head has become clogged, and alert an operator with a time and/or location of the occurrence of an event associated with one or more of the sprinklers.

Camera images may be utilized to detect substrate edges and provide information regarding the centering of the substrate within the fluid dispense system. Camera images may also be utilized to monitoring the location of a cup within the fluid dispense system. The signal processing techniques utilized may include data smoothing, analyzing only certain wavelengths of reflected energy, transforming the data (in one embodiment utilizing a Fourier transform), and/or analyzing a sub-set of the collected pixels of data. The camera image data collected herein may be combined with a wide variety of other data so as to better monitor, characterize and/or control a substrate processing process flow.

Spraying apparatus enabling large-volume generation of particles minute to a Brownian-motion engendering level. The spraying apparatus includes an atomization tank, an atomizing device, a blower, an atomization unit furnished with a liquid-level sensor for measuring liquid level in the atomization tank, a tank unit for supplying liquid formulation to the atomization tank, and a control unit for controlling supply of the liquid formulation from the tank unit to the atomization tank. If the liquid level measured by the liquid-level sensor falls below a predetermined first level h.sub.1, the control unit starts supply of the liquid formulation from the tank unit to the atomization tank, and if the liquid level measured by the liquid-level sensor reaches a predetermined second level h.sub.2 higher than the first level h.sub.1, the control unit halts supply of the liquid formulation from the tank unit to the atomization tank.

The invention relates to a device (10) for providing mist to a surrounding environment, the device (10) comprising a housing unit (12) having an inlet opening (18), an outlet opening (20), and a chamber (22) extending between the inlet opening (18) and the outlet opening (20) along a central axis (24); a nozzle unit (14) including at least one orifice (26); wherein the nozzle unit (14) is arranged in the chamber (22), the nozzle unit (14) being slidable along the central axis (24) between a closing position, in which the nozzle unit (14) closes the outlet opening (20), and an opening position, in which the at least one orifice (26) connects the chamber (22) to the surrounding environment in fluid communication; wherein the nozzle unit (14) transfers from the closing position to the opening position if a fluid pressure at the inlet opening (18) exceeds a predefined threshold; wherein the nozzle unit (14) comprises a deflector part (28) for deflecting fluid in the opening position and for closing the outlet opening (20) in the closing position, wherein the at least one orifice (26) is arranged offset to the central axis (24) between the inlet opening (18) and the deflector part (28); wherein the at least one orifice (26) is configured to guide fluid flowing through the at least one orifice (26) and to lead the fluid towards the deflector part (28). The invention provides an improved device (10) for providing mist to a surrounding environment, which reduces the required amount of fluid and increases the efficiency of the fluid distribution.

A bead flow sensor module includes a housing, a beam, and a sensor. The beam extends into a flow channel of the housing through which a flow of beads and compressed air flows. The sensor outputs a signal indicative of bead impacts on the beam. A system incorporating the bead flow sensor module includes a compressed air source, a bead hopper, and a bead dispenser. The compressed air source delivers a flow of compressed air to the bead hopper. A flow of beads carried by the compressed air discharges from the bead hopper along a flow pathway connecting the bead hopper to the bead dispenser. The bead flow sensor module positioned along the flow pathway outputs the signal from which a bead flow volume through the bead dispenser is determined.
