A mobile cleaning system has a mobile unit allowing for movement of the cleaning system to and around a static vehicle for cleaning, a main cleaning assembly for applying cleaning fluids to a surface of the static vehicle and for scrubbing the surface of the static vehicle (where the cleaning assembly has the ability to pivot, rotate, and/or tilt for various cleaning purposes), a self-contained fluid supply system providing the cleaning fluids used by the cleaning assembly, and a operator control assembly allowing an operator to ride the mobile unit and selectively operate the components of the cleaning system.

An autonomous vehicle (AV) maintenance system engages a user of an AV to assist in maintenance tasks. A sensor interface receives data captured by a sensor of the AV. An issue detector processes the sensor data to detect an issue in the AV. A user interface module instructs a user to perform a maintenance task addressing the detected issue. A verification module verifies that the user successfully completed the maintenance task.

A vehicle drying assembly has a frame defining a path for movement of a vehicle through the drying assembly and a side brush rotatable about a generally horizontal axis. The side brush includes brush segments that extend radially from the axis to contact a side of the vehicle in a direction generally normal to the path, as the first side brush rotates about its generally horizontal axis. The side brush is mounted at a defined height above the ground and at a distance relative to the vehicle along the path, so as to define a no-contact region on the side of the vehicle in which the side brush does not contact the vehicle as the side brush rotates and the vehicle moves through the drying assembly.

In order to provide a treatment installation for treating workpieces that is of simple construction and enables optimised workpiece treatment, it is proposed that the treatment installation should include a treatment chamber and a conveying device, by means of which the workpieces are suppliable to the treatment chamber, are removable from the treatment chamber, and/or are conveyable through the treatment chamber in a conveying direction.

Disclosed herein is a multipurpose cleaning kit which can easily clean hard-to-reach places inside an automobile or a tent during car camping, which is currently popular among people, or camping. The cleaning kit can easily clean hard-to-reach places inside an automobile, such as cracks of seats, by allowing a dustpan having a defrosting scraper integrally formed therewith to be easily assembled with or disassembled from a broom having a brush securely inserted into a handle thereof and adapted to remove dust from air vents inside the automobile (air vents of an air-conditioner) and cracks of the seats, and can be made compact enough to be stored in a pocket on the back of a front seat of the automobile when the broom and the dustpan are assembled together.

Laser cleaning equipment and a cleaning method for a shaft component are provided. The equipment includes: a supporting base assembly; two driving wheel structures on the supporting base assembly, driving wheels of each of which is configured for being close to or away from each other, and the shaft component to be cleaned is placed between the two driving wheel structures; a friction wheel structure that is tangent to driving wheel structure(s) and uses a friction force thereof to drive driving wheel structure(s) to rotate; a connection shaft assembly that coaxially passes through the friction wheel structure; a power driving mechanism, one end of which that faces toward the connection shaft assembly is in drive connection with the connection shaft assembly and is configured to drive the connection shaft assembly to rotate; and a laser cleaning mechanism configured for performing laser cleaning on the shaft component to be cleaned.

The present invention discloses a method and system for protecting the operation of a train under an air pollution environment. The method for protecting the operation of the train under the air pollution environment comprises: acquiring multiple groups of roof and underbody air quality detection data; solving comprehensive roof and underbody air evaluation indicator Q.sub.0 and Q.sub.1 by using the experimental data; calculating an exposure time T.sub.0 of roof components and an exposure time T.sub.1 of underbody components; training a calculation model of pollutant condition about roof component and a calculation model of pollutant condition about underbody component; detecting roof and underbody air quality detection data after the train stops; calling the trained roof and calculation model of pollutant condition about underbody components, and solving roof and underbody component pollution levels, and performing corresponding cleaning on the roof and underbody components according to the solved roof and underbody component pollution levels. The present invention evaluates the exposed status of key components of the train under the air pollution environment, and takes relevant protective measures to ensure normal service lives of the key components of the train.

An improved flow rate metering device that provides for the mixing and dispensing of two or more fluids to form final mixture, for example, for automatic washing of cars and trucks. More specifically, the invention is a system that mixes and ejects chemicals, creating a very precise mixture of one or more chemicals with a dilutant, such as water. The device also has the capability of monitoring an entire chemical dilution and release system, comprising multiple chemicals, and using software to document past and current usage rates, along with predicting future usage rates based upon both past usage rates and environmental conditions.
