The on-actuator reservoirs are designed to prevent liquid flow-back into the loading port and to prevent liquid from flooding into the droplet operations gap in the dispensing zone.

Abstract: Various embodiments relate generally to computer vision and automation to autonomously identify and deliver for application a treatment to an object among other objects, data science and data analysis, including machine learning, deep learning, and other disciplines of computer-based artificial intelligence to facilitate identification and treatment of objects, and robotics and mobility technologies to navigate a delivery system, more specifically, to an agricultural delivery system configured to identify and apply, for example, an agricultural treatment to an identified agricultural object. In some examples, a method may include calculating an amount of light originating from a light source sensed at a location in which an agricultural object is interposed between the light source and an image capture device, causing emission of an obscurant, and directing the obscurant to a region interposed between the light source and the agricultural object.

Abstract: An improvement to a roadside sprayer fixates spray nozzles on a registration plate. The registration plate may include integral tabs depending on the application. Inclination of the tabs is adjustable to place streams and droplets in a desired swath coverage. With the nozzles rigidly mounted onto the plate, the entire plate is notated. The use of the registration plate in a spray unit creates a uniform nutation among the nozzles, thereby reducing variability in droplet placement, and providing a more predictable spray from the nozzles. In other embodiments, the spray unit is utilized in a spray system adaptable to service vehicles, and may be utilized in conjunction with a vegetation engagement device, such as a cutter to engage multiple zones of a roadway right-of-way. Additionally, an improved spray unit includes an electromagnetic field and an attractor to generate plate motion.

Abstract: A method of protecting life, property, homes and businesses from wild fire by applying environmentally-clean anti-fire (AF) liquid spray using a wireless system network supported by GPS-tracking techniques. Intelligence is collected and GPS-specified maps and reports are generated on the wireless system network informing when environmentally-clean anti-fire (AF) chemical liquid should be spray applied to GPS-specified property parcels, prior to the arrival of wild fires, using GPS-tracking AF chemical liquid spraying systems. The preferred clean anti-fire chemical liquid does not depend on water to inhibit the ignition of fire and flame spread, so that, even after a month or two after spray application on buildings and dry brush around homes and the neighborhood, the clean anti-fire chemical continues to work by inhibiting fire ignition and flame spread, and the ability of a wild fire to advance and consume property and homes.
