The lattice structure of the heating elements provides a balance between surface area and heat dissipation, allowing the heating elements to reach a suitable temperature to perform ammonia dissociation, but which are not oversaturated with heat which could result in failure or melting of the heating elements.

Abstract: The present invention is a hand sanitizer, air purification, fogger vehicle mount, or combination thereof, attach to a dashboard of a vehicle. Its purpose is to maximize disinfecting opportunities as a countermeasure to the spread of disease, including COVID-19. As a hand sanitizer, this invention is a hand-free device that minimizes cross-contamination among vehicle patrons during operation. A sensor, activated by hand proximity, sends a signal to a controller, then to a pump to dispense a portion-controlled volume of hand sanitizer. To disinfect airborne antigens, HEPA filtration and UV light are utilized. Pathogen lingering on surfaces are disinfected by a fogger, which dispenses atomized droplets throughout a vehicle. To eliminate exposure to nebulized sanitizer, the controller may receive a wireless signal from outside the vehicle. Independently powered, a vehicle can be sanitized each time it arrives at a destination, made ready to transport the next group of patrons safely.
