A fluid delivery system includes a status indicator and control system comprising a processor. The processor is configured to receive a first signal indicative of a first status of operations of a spray application system. The processor is further configured to provide to an operator of a spray gun, via a display system, a visualization representative of the first status of operations, and techniques to control the fluid delivery system, wherein the spray application system is configured to deliver at least one fluid to the spray gun during operations.

A fire-fighting vehicle includes a boom assembly movably coupled to a chassis, a penetrating nozzle coupled to the boom assembly, an actuator that moves the penetrating nozzle relative to the chassis, and a controller operatively coupled to a sensor. The penetrating nozzle includes a piercing tip and an outlet configured to be selectively fluidly coupled to a supply of fire suppressant. The piercing tip is repositionable relative to a surface of an object having an interior cavity. The outlet supplies fire suppressant into the interior cavity when the piercing tip is within the interior cavity. The sensor provides data relating to at least one of a position and an orientation of the piercing tip relative to the surface. The controller determines an angular orientation of the piercing tip relative to the surface based on the data.

The present disclosure relates to a bioprinter spray head assembly and a bioprinter, wherein the bioprinter spray head assembly comprises an outer nozzle having a second channel and an inner nozzle having a first channel, the inner nozzle is coaxially provided within the second channel, the first channel forms a first material channel, and an annular space between the outer nozzle and the inner nozzle forms a second material channel, which surrounds the first material channel at an outlet of the first material channel, for converging a second material sprayed from an outlet of the second material channel toward a first material sprayed from the outlet of the first material channel, so as to form a fluid printing unit. Such spray head assembly can allow that the second material uniformly wraps the first material at the outlet of the spray head assembly, so as to form a fluid printing unit having a high quality to protect the cells, thereby reducing the cell damage caused by the extrusion pressure and the frictional force subjected in the printing process, so as to improve the survival rate of the cells.

An autonomous and self-mobile apparatus for applying a coating to a surface. The self-positioning apparatus can move into an interior or to an exterior of a structure, and can automatically apply a coating, such as paint, to a surface of the room, or a surface of the exterior of the structure, with little or no human intervention or assistance. The apparatus navigates and applies coatings using its sensors and a computer. In some implementations, the system may also include a storage, recharging, and monitoring unit that interconnects with the apparatus for applying a coating to a surface.

An applicator assembly for treating a contoured surface including an attachment frame configured to secure and position an applicator head. In some embodiments, the applicator head is configured to apply a surface treatment to the contoured surface. The applicator assembly further includes, at least one sensor operatively coupled to the attachment frame and configured to scan the contoured surface and produce a contoured data set. Additionally, the applicator assembly includes an applicator actuator operatively coupled to the attachment frame and configured to manipulate the attachment frame such that the applicator assembly maintains an orientation of the applicator assembly relative to the contoured surface.

A surface treatment assembly for treating a contoured surface includes a surface treatment array formed from a plurality of base structures, each base structure operably coupled to a first phalange structure and a first phalange structure first end. A second phalange structure operatively coupled to each first phalange structure and a phalange joint disposed between each first phalange structure and each second phalange, thereby forming a finger structure. Moreover, at least one applicator head is coupled to a second phalange structure second end of each finger structure and configured to treat the contoured surface. A base structure actuator and a phalange joint actuator operatively coupled to and configured to manipulate the first phalange structure and the second phalange of each finger structure to adjust the surface treatment array relative to the contoured surface.

Location systems and methods for locating paint and other markings on a surface are described. More specifically, but not exclusively, the disclosure relates to smart paint stick devices and methods of use in locating and marking buried utility lines or other buried objects. One system for locating a buried object may include a buried object locator and a paint stick. The locator may include a tracking component configured to detect a location of a buried object. The paint stick may be configured to cause a paint container to dispense paint at a first position associated with the location of the buried object.
