Via NZ Herald: 

The new, 1.55 millimetre-thick contact lens contains an extremely thin, reflective telescope, which is activated by winks.

Released in 2013 and fine-tuned since then, the prototype was unveiled by Eric Tremblay from the Ecole Polytechnique Federale de Lausanne in Switzerland at the American Association for the Advancement of Science annual meeting in California.

The lenses come with smart glasses that respond to the wearer's winks - but not blinks - so that the user can switch almost effortlessly from normal to magnified vision and back.

The wearer winks with the right eye to activate the telescope, and with the left eye to deactivate it.

Well, it seems less threatening than the ED-209.

The Knightscope K5 Autonomous Data Machine is an mobile robotic security guard with a slew of built-in sensors designed to patrol and monitor an area. The egg-shaped rolling robot has GPS and laser scanning built-in and utilizes prediction algorithms and social analytics to identify and assess potential concerns. Data collected by the robot is also made public to help crowdsource those predictions. Knightscope's creators plan to charge an hourly fee to rent the robot that will likely significantly undercut the going price of their human counterparts.
