Hairpin anti-violence

According to the World Health Organization (WHO), 35% of women around the world become victims of violence and sexual assault. Although tear gas can help women defend themselves, they will be useless if the culprit is an acquaintance or when the sister is attacked unexpectedly. The First Sign Hair Clip, a hair clip integrated with security sensors, is designed not only to signal the need for help, but also to collect evidence to ensure that the attacker is prosecuted.

First Sign Hair Clip by US company First Sign Technologies invented looks like any ordinary hairpin, size 12x40x4mm. However, inside the clamp is equipped with a 3-axis accelerometer, a gyroscope and a Bluetooth module, which detects the force acting on the head, from which sounds the alert and sends data. to an app that comes with your smartphone.

Next, the application sends GPS (global positioning system) data, images and sound recorded at the scene to the monitoring center. At the same time, a programmed voice would emit the sentence: 'Help is available and evidence has been gathered' , to counter the attacker. Not only that, your sister's phone also automatically connects with emergency contacts (like police, emergency services) to get help.

'False alerts happen rarely. Our engineering team carefully sets up algorithms sufficiently sophisticated to distinguish the difference between the normal effects of life and those created in emergencies. " - Founder of the company Says Rachel Emanuele. In case of false alarms, the system will be disabled for 15 seconds and the user can then reactivate by pressing the emergency button on the side of the clamp.

The company is raising capital through indiegogo.com, whereby consumers who only contribute $ 50 can own a self-contained security clamp and application.
