The invention is an air and surface disinfection robot designed to autonomously move through incredibly narrow spaces, specific to mass transportation vehicles such as aircraft, trains, busses, or ferries. The robot includes modes to operate in the spaces associated with transportation, such as waiting areas, bathrooms and narrow entry and exit ways.

In the transportation industry, turn around time (the time between two planned trips), is often incredibly short. Existing designs do not allow for a fast enough loading, setup and run time. This invention has been designed to optimize the portability, maneuverability, connectivity (data) and ease of use from other devices designed to disinfect such vehicles.

The invention uses UVC (germicidal) lamps, a proven technology for disinfecting pathogens. The design has been optimized by using a unique open cage design, so the light will transmit from all directions with minimal absorption to components on the device. This in combination with the lamp pattern and the robotics results in a very precise UVC light emission required for adequate, consistent disinfection of the surfaces and the air of mass transportation vehicles.

Finally, the invention consists of real time data streaming and remote operation as data is published through a connected cloud service and then onto the subscribed users.

Provided is a titanium oxide composition that has a high capability to decompose odor-causing substances, is less likely to cause re-emission of an odor-causing substance(s) due to adsorption of water, and exhibits an excellent particle dispersion stability. The titanium oxide composition contains titanium oxide particles, a component A and a component B. The component A is at least one kind selected from a group of sepiolite and attapulgite, and the component B is at least one kind selected from a group of high silica zeolite and hydrophobic silica. A mass ratio of the component A to the titanium oxide particles is 0.75 to 3.25, and a mass ratio of the component B to the component A is 0.25 to 3.0. Also provided is a member having such titanium oxide composition on its surface.

Apparatus, methods and instructions for disinfecting air. The apparatus may include, and the methods may involve, a fixture. The fixture may include a germicidal light source. The fixture may include a fan. The fan may circulate air through a volume into which the germicidal light source propagates germicidal light. The light source may be configured to emit, upward from a horizontal plane, a beam that, absent reflection off an environmental object, does not cross the horizontal plane. The apparatus may include a shield that prevents light from the light source from crossing the horizontal plane. The sensor may face upward from the horizontal plane. The sensor may face downward from the horizontal plane.
