This handout picture released by Japan's lingerie maker Ravijour on January 23, 2014 shows a high-tech bra "True Love Tester" equipped with a special mechanical hook on its center in Tokyo. The "True Love Tester" uses sensors and a special gadget linked to a mobile device to analyse the pattern and speed of the user's heart beat in the heat of the moment. If the app determines the woman's feelings are for real, the clasp at the front pops open to allow matters between lovers to take their course. /AFP
