This intriguing drone concept drops packages straight into your hands

Technology research company Cambridge Consultants has unveiled a drone delivery

concept called DelivAir that delivers a package directly into someone’s hands, using coded patterns sent via a phone’s LED flash to identify the recipient. The company says this type of delivery is ideal for items that are needed instantly or critically like a first aid kit to a hiker, emergency relief packages to disaster areas, or for delivering medical supplies like an EpiPen. Delivering a package is a two-stage process: first, the DelivAir drone uses GPS to locate a person via their smartphone. Then, it switches to optical tracking and a 3D-imaging and ranging system to locate and authenticate the person receiving the package when they come into view. Once the drone reaches the delivery area, the recipient points their mobile phone’s flash at the drone, which blinks the coded pattern. The drone hovers at a safe distance above the flashing LED, verifies the code, then lowers the package down on a stabilizing winch. The drone then returns to base.                                                                                                                  https://www.theverge.com/2017/10/4/16417986/delivair-drone-concept-led-flash-coded-cambridge-consultants
