Amrita Centre for Cyber Security Launches Safety Devices for Personal Protection.The personal safety device - designed at the suggestion of Mata Amritanandamayi - is just 3.5cm X 3.5cm and can be carried on one's person without attracting undue attention. The trigger may be built into the device or placed at another location on the individual's body, behind the ear or tucked at the waist, for example.
