 the Punggol Oasis Terraces mall, including: a) NTUC FairPrice for grocery deliveries, b) CM Logistics and DHL Express for parcel deliveries, and c) “Foodpanda” for food and grocery deliveries. Camello has also been deployed to transport spare parts at SMRT Corporation Bishan Depot in Singapore. The Otsaw Disinfection Ecosystem Comprised of AirGuard, O -RX, and TreX, our Ultraviolet -C(“UV -C”) Disinfection Ecosystem provides an integrated and comprehensive disinfection solution for indoor spaces. UV -Crefers to a specific ultraviolet wavelength. There are three categories of ultraviolet light wavelengths, UV -A, UV -B, and UV -C. UV -Cwavelengths are between 200 and 300 nanometers and are proven to be effective to eliminate microbes. Our UV -CLED technology is lab -testedto provide 99.9% air and surface disinfection efficacy and is effective in disinfecting against various viruses, including the COVID -19virus. Traditionally, conventional UV lamps were used to disinfect air and surfaces. Our UV -CLEDs are not only 70% more energy -efficientcompared to conventional mercury -basedUV lamps but are also much safer. Unlike conventional mercury lamps that emit harmful UV -Aand UV -Bradiation, our UV -CLEDs emit only UV -Cand are non -cancerousto humans. UV -CLEDs also have a general lifespan of over two years, which is longer than conventional UV Lamps. Our UV -CDisinfection Ecosystem has a wide array of applications and can operate in various scenarios, particularly in hospitals, healthcare facilities, hotels, hospitality facilities, retail stores, shopping malls, offices, and large working spaces. For instance, AirGuard can be installed in the HVAC system of a shopping mall to disinfect airflows throughout retail shops, food courts, lobbies, bathrooms, and elevator systems. A typical mall with a 36ft atrium with a total area of 10,000ft 2could be purified at a virus reduction rate of 98% via AirGuard UV -Cdisinfection in 10 minutes. Moreover, O -RXrobots may autonomously patrol and disinfect mall corridors and pathway at a rate of up to 2,500 square feet per hour. O -RXrobots may utilize its lift integration technology to maximize its coverage between multiple floors
