Research Centre Imarat (RCI), the Hyderabad-based lab of Defence Research and Development Organisation (DRDO), has developed an automated UVC sanitisation cabinet.
Called the Defence Research Ultraviolet Sanitiser (DRUVS), it can sanitise mobile phones, iPads, laptops, currency notes, cheque leafs, challans, passbooks, paper and envelopes.
Proximity sensor switches, clubbed with a drawer opening and closing mechanism, makes the operation totally automatic and any form of contact unnecessary.
The cabinet provides 360 degree exposure of UVC to the objects inside.
No operator needs to wait or stand near the device as once the sanitisation is done, the system goes into a sleep mode.
The RCI has also developed an automated UVC currency sanitising device, called NOTESCLEAN.
DRUVS can sanitise bundles of currency notes, but disinfection of each currency note using it would be time consuming.
To avoid this, a sanitising technique has been developed, wherein loose currency notes have to be put at the input slot of the device which then passes the notes one by through a series of UVC lamps for complete disinfection.
In recent days, DRDO units have developed many implements and devices to fight COVID-19.
These include special N-99 masks, sanitisers, personal protective gear to guard against chemical, biological, radiation and nuclear-related activities. Also in the works is a range of software, including one that will track people under quarantine.
DRDO is also working on a vaccine for COVID-19.
