DavekNY app has a new way for your umbrella to communicate with you, reminding you that you’re about to leave it behind. Hidden in the handle of this sleek umbrella is a tiny Bluetooth-based "proximity chip."  This chip broadcasts a silent signal, read by your smartphone. By reading data from the chip to your phone, we’re able to build an invisible leash between your umbrella—and you. If the distance between the chip and your phone exceeds a certain distance—30 ft or so—the umbrella would send a reminder to your phone.  Never forget your umbrella again!
