Japanese teenagers Mami Harashima (R) and Takeshi Saito display their "Lovegety" matchmakers at a Tokyo street May 14. Japanese singles desperately seeking soulmates are turning to the pocket alarm that bleep and flash when a likely lover is close by. The alarms can be set in three modes according to the kind of relationship required; friend, playmate or lover. When the man or woman of your dreams is within 4.5 metres (15 feet) and assuming they are also equipped with the mechanical matchmaker, Lovegety starts bleeping. A flashing green light means you are both in "lover" mode. The electronic cupids go on sale with a price of 2,980 yen ($22).
