A continuous dust accumulation monitoring system, device and method monitors and measures dust accumulation via an enclosure and a machine vision subsystem which can include a digital camera. A dirty optics detection subsystem monitors optical clarity and can invoke a cleaning assembly to help maintain clarity of optics for monitoring and measuring dust accumulation.

A self-cleaning and anti-adhesion apparatus for marine instruments includes an installation frame. A first end of the installation frame is fixed with an installation base, and a second end of the installation frame is movable with a screw rod. The upper end of the installation base is movable with a first rotation base. A wire netting ball used for holding a sensor is installed above the first rotation base. The wire netting ball is fixedly connected with the installation base. The top end of the screw rod is fixedly connected with a first end of the flexible connector, and a second end of the flexible connector is fixedly connected with a floating bladder. The screw rod is screwed with an inner wheel of an internal meshing ratchet mechanism, and an outer wheel of the internal meshing ratchet mechanism is fixed inside the mounting ring.

Automatic emitter point cleaners are disclosed. An automatic emitter point cleaning system includes: a fan configured to direct a stream of air through an air path; a point emitter configured to produce at least one of positive ions or negative ions within or proximate to the air path; a brush; a first gear coupled to the brush and configured to move the brush into contact with the point emitter; a second gear to engage the first gear; and a motor to actuate the second gear such that the second gear actuates the first gear to move the brush past the point emitter.

The present disclosure provides a roller for cleaning a backside of a wafer. The backside of the wafer has a central region and a periphery region surrounding the central region. The roller includes an upper element, a bottom element, and an axis element for connecting the upper element and the bottom element. The upper element of the roller is configured to contact with a frontside of the wafer. The bottom element is configured to contact with the backside of the wafer and remove particles from the periphery region of the backside of the wafer. The bottom element is made of materials selected from a group comprising abrasive pads, sand papers, and asbestos.

A cleaning system includes at least one cleaning module configured to receive a substrate after a chemical mechanical polishing (CMP) process and to remove contaminants on the substrate using a cleaning solution. The cleaning system further includes a cleaning solution supply system configured to supply the cleaning solution to the at least one cleaning module. The cleaning solution supply system includes at least one temperature control system. The at least one temperature control system includes a heating device configured to heat the cleaning solution, a cooling device configured to cool the cleaning solution, a temperature sensor configured to monitor a temperature of the cleaning solution, and a temperature controller configured to control the heating device and the cooling device.

A pet hair removal apparatus has a plurality of engagement members. The apparatus has a handle and connected base member. On the base member is one or more engagement members, such as lugs, protrusions or frustums. On the lower surface of one of the engagement members is one or more striations, ribs, squeegees or ridges. The striations, ribs, squeegees or ridges operate in an operational engagement position to remove pet hair from the surface of an inanimate object, such as a couch or other fabric. This operational engagement position for the striations, ribs, squeegees or ridges is one of a number of other operational engagement positions for the pet hair removal apparatus.

A coating method of a board for producing a concrete product and a board coated by the same are proposed. The coating method is advantageous in that the whole surface of a board can be rapidly coated and dried to prevent surface corrosion of the board and to prevent further corrosion on a damaged surface of the board, thus improving the durability of the board and the quality of the produced concrete products. The coating method includes: removing residues existing on an outer surface of the board by blowing high-pressure air to an upper surface and a lower surface of the board for producing a concrete product; coating by spraying coating liquid to the outer surface of the board from which the residues have been removed; and drying the coating liquid by blowing high-pressure air to the outer surface of the board.

The invention relates to a cleaning tool for an aerosol-generating device. The FIG. 1 cleaning tool comprises a cleaning head and a handle. At least a part of the cleaning head is rotatably mounted in the handle. The cleaning tool further comprises at least one suspension element arranged between the cleaning head and the handle. The suspension element is arranged to engage the cleaning head or the handle to prevent relative rotation between the cleaning head and the handle, if a torque below a predetermined threshold is applied between the cleaning head and the handle. The suspension element is configured to disengage the cleaning head or the handle, if a torque above a predetermined threshold is applied between the cleaning head and the handle

A smoke and dust treatment apparatus for welding, said apparatus comprising a polishing and dust extraction module and a smoke and dust purification module. The polishing and dust extraction module comprises a double-layer dust extraction cover (3), a protective cover (2), an industrial brush (4), a first air guide portion, a second air guide portion (24) and a drive motor (22), the drive motor (22) driving the industrial brush (4) to rotate at high speed to perform polishing. During welding and polishing, a mechanical arm (6) drives the double-layer dust extraction cover (3), and a suction hole (20) of the double-layer dust extraction cover (3) and a suction guide hole (19) on the industrial brush (4) simultaneously take in toxic gas and debris such as iron filings.
