8 results about "SAFE AIR" patented technology

SAFE AIR (Simulation of Air pollution From Emissions Above Inhomogeneous Regions) is an advanced atmospheric pollution dispersion model for calculating concentrations of atmospheric pollutants emitted both continuously or intermittently from point, line, volume and area sources. It adopts an integrated Gaussian puff modeling system. SAFE AIR consists of three main parts: the meteorological pre-processor WINDS (Wind-field Interpolation by Non Divergent Schemes) to calculate wind fields, the meteorological pre-processor ABLE (Acquisition of Boundary Layer parameters) to calculate atmospheric parameters and a lagrangian multisource model named P6 (Program Plotting Paths of Pollutant Puffs and Plumes) to calculate pollutant dispersion. SAFE AIR is included in the online Model Documentation System (MDS) of the European Environment Agency (EEA) and of the .Italian Agency for the Protection of the Environment (APAT).

A grinding head motor

ActiveCN121727278BThermodynamicsLiquid water
This application discloses a grinding head motor, relating to the field of motor technology. It includes a motor body, an output shaft disposed at one end of the motor body, and a controller. The controller is integrated and installed on the port section of the motor body away from the output shaft, and the controller and motor body are designed as a single integrated housing. The surfaces of the motor body housing, output shaft, and exposed connecting parts are coated with an anti-corrosion coating. In this application, when positive pressure is generated inside the motor, the seal is automatically enhanced to prevent internal humid and hot gas from carrying trace amounts of moisture from leaking out. When the motor stops cooling and generates negative pressure, a unique pressure balance channel with a hydrophobic and breathable membrane becomes the only safe air intake path. It effectively blocks external liquid water, water mist, and dust, allowing only dry air to slowly enter to balance the pressure. This fundamentally eliminates the possibility of internal component corrosion and short circuits caused by the intake of moisture and contaminants due to negative pressure.
