Various embodiments of an apparatus, methods, systems and computer program products described herein are directed to an agricultural observation and treatment system and method of operation. The agricultural treatment system uses a treatment unit for emitting a laser at agricultural objects. The treatment unit is configured with a treatment head assembly that includes a moveable treatment head with one or more laser emitting tips. A first and second motor assembly are operated by the treatment unit to control the movement of the treatment head. The first motor assembly includes a first motor rotatable in a first rotational axis. A first linkage assembly is connected to the first motor and the treatment head assembly. The first linkage assembly is rotatable by the first motor. The second linkage assembly is rotatable by the second motor.

An electrostatic coating system including of a novel technique of height adjustment through pressure sensing and feedback mechanism in twin-phase air-assisted and forced-liquid flow based electrostatic nozzle(s). A variable height electrostatic edible coating system provides uniform and efficient coating to ensure shelf-life extension, improved nutritional value and enhanced sensory attribute.

An additive manufacturing (AM) system includes a housing defining a chamber, a build platform disposed in the chamber at a first elevation, and a lower gas inlet disposed at a second elevation and configured to supply a lower gas flow. The AM system includes a contoured surface extending between the lower gas inlet and the build platform to direct the lower gas flow from the second elevation at the lower gas inlet to the first elevation at the build platform, where the contoured surface discharges the lower gas flow in a direction substantially parallel to the build platform. The AM system also includes one or more gas delivery devices coupled to the lower gas inlet to regulate one or more flow characteristics of the lower gas flow, and a gas outlet configured to discharge the lower gas flow.

The present invention relates to a method and apparatus for delivering droplets of fluids onto an open tray containing poultry, the tray being stationary. According to the invention, the method comprises the following steps: (a) a movable arm is moved over the tray in translation in a first direction, said arm supporting a first set of dispensing nozzles and a second set of dispensing nozzles, said nozzles of each set being arranged to cover the entire dimension of the tray in a second direction perpendicular to the first direction; (b) initially, droplets of at least one first fluid are dispensed by spraying using the first set of dispensing nozzles; (c) and then at least one second fluid, distinct from said at least one first fluid to be sprayed, is dispensed by ejecting individual drops by means of the second set of dispensing nozzles.

An injection control device for a fuel injection valve includes: a current detection unit, a current area correction control unit, a storage unit, and a reference current value correction unit. The current area correction control unit corrects, based on an energization current profile, an area correction amount of an energization time to equalize the integrated current value of the energization current profile and an integrated current value of the detected current, and obtains the integrated current value of the current based on an attainment time from a start of energization of the fuel injection valve to an attainment of each of plural reference current values. The storage unit stores a reference attainment time. The reference current value correction unit corrects each reference current value based on a difference between the reference attainment time and a detected attainment time at a time of actual drive.

Disclosed is sprinkler system. The system comprises a gate valve. Further, a sprinkler frame is mounted on the gate valve. The sprinkler frame further consists of wires for connection. The system further comprises a generator. The generator is mechanically coupled with a rotor and a generator base. Further the system comprises of an electronic component. The system is housed in a sprinkler housing.

Exemplary backpressure monitoring apparatuses may include a fluid supply source having a fluid port. The backpressure monitoring apparatuses may include a flow control mechanism fluidly coupled with the fluid port. The backpressure monitoring apparatuses may include a delivery tube fluidly coupled with the flow control mechanism and the fluid port. The backpressure monitoring apparatuses may include a pressure differential gauge fluidly coupled with the delivery tube. The pressure differential gauge may include an interface mechanism that is engageable with an outlet of a fluid flow device.

A sprayer for spraying fluid includes a pump, a motor that drives the pump, a drive cycle indicator, a wireless module configured to send and receive information, and control circuitry. The drive cycle indicator outputs an indication of cycle status of the pump. The control circuitry is configured to receive the plurality of cycle status indications of the pump, determine a plurality of output values representing paint spray fluid output volume over a plurality of time windows based on the plurality of cycle status indications of the pump, store the plurality of output values in memory, and cause the wireless module to transmit one or more of the stored plurality of output values externally from the sprayer.

An automated mobile sprayer (AMS) includes a mobile base, an applicator arm supported by the mobile base, and a nozzle extending from the applicator arm. The nozzle receives fluid from a fluid supply and generates an atomized fluid spray for application to a surface. The applicator arm moves vertically relative to the mobile base and the surface to cause the nozzle to generate a vertical fluid stripe. The mobile base moves laterally relative to the surface to cause the nozzle to generate a horizontal fluid stripe.

A system for determining the presence of fluid flow in a pipe is provided. The object of the invention is achieved by a vibration detector attached to the pipe.
