Fighting sexual deviants: Activist invents `ring of defence' for women

[1]

Bengaluru: Finger rings worn by women for fashion or tradition can also act as a self-defence weapon. With incidents of attack, gang rape and sexual assault being reported against women across the country, the women need to protect themselves from marauding offenders.
Imran Khan from Davangere, who holds a B.Pharma and MBA degrees and is the chairman of Save My Sister Trust, has invented a finger ring (his patented product) that can help women protect themselves from assault, molestation or rape.
Khan told Deccan Chronicle, "I have found a solution with which the women can protect themselves. I developed a working model within a month of the Delhi gangrape incident. Compared to other jewellery worn by women, finger rings are tough to snatch, so I came up with this idea."
He said, "The ring has a micro tank, micro needle, micro pump and a Radio-Frequency Identification (RFID) tag on the top with a dual lock mechanism. The micro-tank stores Capsaicin (a chemical compound that stimulates chemoreceptor nerve endings in the skin, especially the mucous membranes), while micro-pump and micro-needle help in injecting the drug into the attacker's body. The RFID tag is helpful in preventing misuse of the device. All that the victim needs to do is unlock the mechanism and inject the chemical into the attacker. Once the drug is injected, the attacker will feel int­ense pain, itching and burning sensation. But it will not kill the attacker. We have che­cked the merits and drawbacks of the mechanism." 
As part of the Save My Sister campaign, the Trust is writing to Prime Minister Dr Manmohan Singh to come up with a uniform helpline number and a dedicated online complaint mechanism for women.
How it works? 
Troops fanned out on Cairo’s main streets, ringed key facilitiesThe self-defense ring contains a micro-tank, micro-needle, micro-pump and a Radio-Frequency Ident­ification (RFID) tag the top along with a dual lock mechanism. The micro tank stores the chemical, Capsaicin, while micro pump and micro-needle help in injecting the drug into the attacker's body. The chemical causes intense pain, burning sensation and itching, but it does not kill anyone.
The RFID tag helps in preventing it misuse. The user needs to unlock the locking mechanism and inject the chemical. As the ring is protected by a dual lock mechanism, it can be worn comfortably.
The ring, which was launched in the city on Friday, is available through the Save My Sister helpline number: 080-64500112.
