An agricultural vehicle comprises a left frame and a right frame. A left wheel is rotatable with respect to the left frame and a right wheel is rotatable with respect to the right frame. A first leg extends upward from the left frame and a second leg extends upward from the right frame to connect the legs to the beam. A data processor estimates a reference point on or below the vehicle and an angular orientation or attitude of the beam relative to the reference point based on positions of location-determining receivers associated with the beam. An upper carriage is laterally movable along the beam. A lower carriage is suspended from the upper carriage by a plurality of vertical supports, such that a target lateral position of the upper carriage establishes an actual lateral position of the lower carriage.

A method of dispensing a brushable substance onto a surface comprises (1) with a cartridge positioned inside a sleeve between an inner tubular sleeve wall and an outer tubular sleeve wall, circumscribing the inner tubular sleeve wall, and also positioned between a twist-lock pressure cap, hermetically coupled with the cartridge, and a valve, communicatively coupled with the cartridge, linearly moving an annular plunger, received between an inner tubular cartridge wall and an outer tubular cartridge wall, circumscribing the inner tubular cartridge wall, toward the valve along a first axis to urge the brushable substance from the cartridge, through the valve, and to a brush that is communicatively coupled to the valve; and (2) controlling flow of the brushable substance from the valve to the brush.

A manufacturing apparatus for a semiconductor device, the manufacturing apparatus including a spin chuck configured to fix and rotate a wafer; a nozzle configured to spray a chemical toward the wafer; a lateral displacement sensor configured to measure a displacement variation to a lateral surface of the wafer while the spin chuck is being rotated; and a controller configured to control a position of the nozzle by using the displacement variation while the spin chuck is being rotated.

A sprinkler system for lawns and landscaping is custom-fitted to each particular lot or area to be irrigated. Each in-ground, pop-up, rotating sprinkler head has a pattern defining plate fitted therein having a central opening made therein, as by laser cutting, solid particle deposition, or the like, the opening being congruent with the area to be watered, as adjusted for any sloped portions of the area. A pattern sampling aperture aligned with spray nozzles of the sprinkler rotates about the opening in the defining plate, feeding an amount of water to each radial line of the area about the sprinkler sufficient to reach from the sprinkler position out to the periphery. A speed control comprising a spring-biased cam and an opposing turbine wheel in the water flow slows spray head rotation at arc portions of longer water throw and speeds rotation where the throw is shorter, thus to obtain substantially uniform water coverage over all parts of the area served by each sprinkler head.

The present invention provides a method for aligning spans using real-time kinetics (RTK) data communicated through a power line carrier system. According to a further preferred embodiment, the method of present invention includes the steps of: receiving a first set of GPS location data and second set of RTK data; comparing the first set of GPS location data with the second set of RTK data; calculating RTK error correction data; creating an RTK error correction data signal containing RTK error correction data; modulating the RTK error correction data signal for transmission on a power line carrier; transmitting the RTK error correction data signal through a power line BUS onto a power line to a last drive tower; de-modulating the RTK error correction data signal; calculating the location of the last drive tower using the RTK error correction data; calculating a straight, center line between the pivot and the last drive unit; calculating the relative distances between each intermediate drive tower and the calculated center line; and controlling the speed or average run time of each intermediate drive tower to reduce distance between their current locations and the calculated center line.

A portable, hand-held electrospinning or electrospraying apparatus and system, method, and portions thereof, comprised of a durable portion of the hand-held apparatus and a consumable portion of the hand-held apparatus. The consumable portion of the hand-held apparatus, which may contain the solution to be output in electrospin or electrospray fashion, may be replaced in whole or in part to provide additional or alternative solution. A base station may be provided, and can output high voltage and communication signals to the hand-held apparatus to enable the electrospin or electrospray operation by the hand-held apparatus.

A real-time measurement and marking apparatus is provided. The disclosure providing a portable marking device comprising: a housing including a main housing structure and a can cover, the main housing structure having a front open end, a rear nozzle end, a top surface, a bottom surface, and a pair of opposing side walls, wherein at least one of the side walls defines an aperture, the can cover having a rear open end, a front closed end, the can cover extending at the rear open end to selectively engage with the aperture defined by at least one of the side walls releasably securing a spray can within the housing; a nozzle member positioned at the rear nozzle end of the of the main housing structure; an optical measuring apparatus for real-time measuring of a distance between a point of focus and the portable marking device activated by one or more buttons.

It is often desirable to apply graphic output to surfaces that are large, irregular, and/or contoured. Application of graphic output on large or complex surfaces may be accomplished by projecting a pattern onto the surface using a projector disposed at a fixed location with respect to the surface. The graphic output is mapped to the projected pattern, by precisely positioning the print head with respect to the projected pattern using a robotic or similar actuated articulated positioning device, graphic output portions may be disposed in each of a plurality of defined locations to form a seamless, large scale graphic output.

An armrest control center can be configured on with respect to an armrest of a chair in an operator cab of an agricultural machine to have physical inputs which can be quickly and easily controlled by an operator in the cab to affect automatically controlled sprayer boom functions so that the operator is not distracted by cumbersome menus on a computer screen. Such physical inputs can include push buttons and/or a joystick. Such sprayer boom functions can include activating or deactivating automatic sprayer boom height control, adjusting automatic sprayer boom height settings, and folding and/or unfolding the sprayer boom.

The present invention is directed to a spray applicator for spraying a tissue treatment medicant onto a tissue that has a container containing the medicant and is positioned at a proximal end of the spray applicator; a spray tip positioned at a distal end of the spray applicator; a cannula connecting the container with the spray tip; an actuatable dispensing mechanism at a proximal end of the applicator to express the medicant from the container through the cannula and through the spray tip toward the tissue; an optional pressurized gas source discharging a gas through the cannula in the vicinity of the spray tip or inside the spray tip; and a distance indicator that provides indicia of the distance between the spray tip and the tissue but does not prevent positioning the spray tip closer to the tissue than a defined distance for the distance indicator.
