Combined gas and particulate time-series with machine learning detect smoking, vaping, and cleanliness events in shared vehicle cabins.
Chamber temperature drop is measured after each wafer to skip or trigger lamp preheating, cutting dummy wafer use while keeping thermal history uniform.
An integrated band pass filter and lens assembly concentrates selected light onto a Fabry-Perot filter to suppress stray light and preserve detection accuracy.
Integrated LIDAR and ambient-light channels share aligned pixels, reducing cross-modal registration effort while improving depth and spectral fusion.
