A system includes a manual tool data system having a manual tool data monitoring system configured to monitor one or more manual tools, a manual tool data acquisition system configured to acquire data corresponding to one or more operational parameters of the one or more manual tools, a manual tool data analysis system configured to analyze the data acquired by the manual tool data acquisition system, and a manual tool messaging system configured to generate messages based on the data analyzed by the manual tool data analysis system.

A rotor-suspended boom sprayer includes a sprayer body, a pair of polygonal rollers mounted on the sprayer body, and two rotor wide spray booms which are respectively located on either side of the sprayer body when unfolded, the two rotor wide spray booms being unrolled and rolled up by the polygonal roller. Each rotor wide spray boom includes at least one electric motor, at least one propeller correspondingly connected to the electric motor, several sets of rotor spray boom units connected to each other, and several spraying heads provided on the rotor wide spray boom. A self-balancing fixed height system is provided on each rotor wide spray boom to acquire height information and regulate balance and height above the ground of the boom, and the sprayer body is equipped with a main control system connected to the polygonal roller, the electric motor, and the self-balancing fixed height system.

An applicator making it possible to apply a coating product on a surface to be coated, including at least one row of nozzles, among which at least the first nozzle in the row includes a valve, the applicator further including at least one distance sensor, to measure an application distance of the first nozzle from a point in front of the latter on a path of the applicator, and an electronic control unit of the valve, which is programmed to collect the distance measured by the distance sensor and, based on the collected distance value, to open or close the valve.

A method of generating a building assembly that includes spraying a coating material onto a plurality of pieces of substrate disposed on a first assembly face. The spraying includes spraying the coating material onto the plurality of pieces of substrate via a sprayer configured to apply the coating material to a target surface via a nozzle coupled with a mobile storage container storing the coating material, the coating material impregnating voids of the substrate. The method also includes allowing the coating material impregnating the voids to dry and harden and become rigid to generate the building assembly.

By measuring a position of a spray gun relative to a physical surface to coat, using data on technical characteristics of the spray gun, like a spray cone the spray gun may produce and data on a coating fluid used, characteristics of a coating layer thus physically deposited may be reconstructed. With data being recording during the spray job, this is faster and more accurate than measuring layer thickness at various locations, either pre-determined or randomly. By determining flow characteristics in a spray cone and position of the spray cone relative to the surface over time and using a model of the spray cone, deposition of the layer of coating may be determined and the final layer, cured or uncured, may be reconstructed, including thickness.

A three-dimensional object printing apparatus includes a liquid discharge head having a nozzle surface, a moving mechanism that changes a position and a pose of the liquid discharge head relative to a three-dimensional workpiece, and a controller. The workpiece has a first surface and a second surface that forms a corner bent or curved in a concave shape between the first surface and the second surface. When an axis along a scanning direction of the liquid discharge head with respect to the workpiece in a first printing operation of performing printing on the first surface is a first scanning axis and a normal vector of the nozzle surface in the first printing operation is a first discharge vector, the controller controls the driving of the moving mechanism such that the first discharge vector has a component in a direction toward the second surface along the first scanning axis.

A portable, hand-held electrospinning or electrospraying device and system, method, and portions thereof are described. Such device can be for electrospinning or electrospraying a predetermined solution toward a deposit surface. The device can have a durable portion, a semi-durable portion, and a consumable portion. The consumable portion can be received and held by the semi-durable portion, and the semi-durable portion holding the consumable portion can be removably coupled to the durable portion.

The present invention discloses a device for controlling the application of insecticides for indoor residual spraying using a sprayer comprising a lance with a spray nozzle, a distance sensor configured to measure the distance between the spray nozzle and the surface being sprayed, an indicator of the distance measured by said sensor, and an indicator of the spraying rate and means of attachment to the sprayer lance and a pipe which allows the insecticide to pass through, and in that the indicator of the distance measured comprises a luminous device which changes colour according to the distance measured by said sensor; a method of applying insecticides for indoor residual spraying by the use thereof, the use thereof to control the application of insecticides and a sprayer which comprises a control device according to the present invention.

A method for inspecting and repairing a surface of a component of a gas turbine engine, the method including: inserting an inspection and repair tool into an interior of the gas turbine engine; inspecting the surface of the component with the inspection and repair tool; performing a repair of the surface of the component with the inspection and repair tool from within the interior of the gas turbine engine, the inspection and repair tool remaining within the interior of the gas turbine engine between inspecting the component and performing the repair of the surface of the component.

A method of supporting a rotating member of a tailstock includes rotating a rotating member coupled to a workpiece support slidably mounted in a housing of the tailstock, causing the rotating member to shift along a longitudinal axis in a first direction, and measuring an amount of vertical displacement of the rotating member.
