IBM has recently secured a patent for drones that deliver drinks to individuals in an office based on their cognitive state. The patent claims a method for delivering a drink to an individual comprising the steps of: connecting a drink to an “unmanned aerial vehicle” (“UAV”), scanning a group of people to identify those with “sleepy cognitive states”, and flying the UAV to the individuals with sleepy cognitive states to deliver the drink.

 It will be interesting to see how this technology develops as IBM continues to venture into the field of artificial intelligence. Read more here.
