The present disclosure relates to automated or remotely controlled methods and apparatuses for cleaning and drying soiled external 2-D or 3-D image sensor surfaces such as objective lenses on Light Detection and Ranging (“LIDAR”) sensors when mounted in a configuration that is exposed to dirty environments.

A fluid spray nozzle includes a first member that is configured to be fixed to a sensor or a mounted portion to which the sensor is mounted, and a second member that is fixed to the first member. The first member has a fluid inlet and a first fluid passage that is connected to the fluid inlet. The second member has a second fluid passage that is connected to the first fluid passage, and a spray port from which the fluid that has passed through the second fluid passage is sprayed onto a predetermined location of the sensor.

A sensor-cleaning apparatus includes an upper piece, a lower piece fixed to the upper piece, a plurality of inserts inserted into the upper piece, and a plurality of nozzles. The upper piece and the lower piece form a tubular segment that is elongated along an arc of a circle and encloses a chamber. Each nozzle is formed of the upper piece and one of the inserts. Each nozzle includes a deflection surface and a tunnel from the chamber to the deflection surface, and each tunnel is partially formed of the upper piece and partially formed of the respective insert.

A flush assembly for a plumbing fixture, the assembly comprising a sprayer body, wherein the sprayer body comprises a bottom wall, a front wall, and a rear wall, the sprayer body is configured to be in fluid communication with a water source, and the sprayer body bottom wall comprises a first outlet through which flush water is delivered during a flush cycle. The first outlet may comprise a slot shape and/or an arc slot shape. The flush assembly provides a large flush profile.

Methods and apparatus for vacuum forming and subsequently applying topical coatings fiber-based food containers. The slurry includes one or more of an embedded moisture barrier, vapor barrier, and oil barrier, and the topical coating comprises one or more of a vapor barrier, a moisture barrier, an oil barrier, and an oxygen barrier. For food containers having deep sidewalls, a spray coating system includes a first nozzle for applying a full cone spray pattern to the bottom surface of the container, and a second nozzle for applying a hollow cone spray pattern to the inside surfaces of the side walls.

A coating applicator vehicle is configured to selectively discharge a flow of liquid emulsion and aggregate onto a roadway. The vehicle includes a rolling chassis and a powered spraying assembly supported by the chassis. The spraying assembly includes a spray bar assembly including a shiftable spray boom and a plurality of spray nozzles.

The invention relates to a spray nozzle comprising an elastomeric tube (1) comprising a proximal end (7) through which a fluid is intended to enter said tube (1), and a distal end (8). The spray nozzle also comprises a slit (9) formed in the elastomeric tube (1) between the proximal end (7) and the distal end (8), for spraying the fluid out from the elastomeric tube (1). The elastomeric tube (1) includes a reinforcing element (10, 11) for limiting deformation of the elastomeric tube (1). By providing a slit in a tube between the proximal and distal ends of the tube, the slit can be sized to provide a broad spread pattern to the spray. The reinforcing element prevents over-expansion or deformation of the elastomeric tube.
