Title: Automated decontamination of complex areas
IPC: A61L2/18
Filed: 2022-03-14
Abstract: PROBLEM TO BE SOLVED: To provide mobile decontamination devices and methods of using the devices for decontaminating various areas, such as aircraft cabins. 
     SOLUTION: A mobile decontamination device comprises at least one aerosol dispersing nozzle and at least one aerosol directing fan. The nozzle disperses disinfectant in the aerosol form, while the fan directs this aerosol to surfaces being decontaminated. Aerosol dispersing parameters, such as the nozzle and fan orientations, dispersing rate and fan speed, are determined based on area characteristics. Specifically, orientations of different surfaces, temperature, humidity and/or other like characteristics may be considered. Some characteristics may be obtained after the mobile decontamination device is deployed in the area, e.g., using its sensors. Other characteristics, such as area layout, may be preloaded before the mobile decontamination device is deployed. The dispersing parameters are determined to ensure thorough decontamination of the surfaces in the area.
