Amazon patents system to defend drones against hackers, jammers … and arrows

Alan Boyle for GeekWire:  If there are any Robin Hoods out there who are thinking about shooting down drones while they’re making deliveries, Amazon has a patented plan to stop you.

The patent, filed in 2014 but published just last week, lays out countermeasures for potential threats ranging from computer hacking to lightning flashes to bows and arrows.

If nothing else, the 33-page application illustrates how many things could possibly go wrong with an autonomous navigation system for unmanned aerial vehicles, or UAVs.

The “compromise system” that Amazon’s engineers propose relies on an array of sensors to orient the drone based on the sun’s position in the sky, if need be. That’s in case the drone gets confused by, say, lightning or a muzzle flash.  Cont'd...

Dynatect Automated Machine Safety Roll-Up Doors

Need to increase safety? Are you using light curtains? Is space a concern? Dynatect's Gortite® VF Automated Machine Safety Door combines safety technology, speed, and a physical barrier to isolate hazardous operations. Use of a physical barrier with safety sensors can save up to 30 square feet of manufacturing space. Using the ANSI minimum safety distance formula, the Gortite® VF Door limits the depth penetration factor and average approach speed, allowing closer location of the safeguarding device. Unlike light curtains, which can't contain process hazards, an automated machine safety door can isolate common workplace debris. This physical barrier is designed to contain process driven hazards such as weld sparks, UV flash, and light debris. Thus, the operator can maintain closer proximity to the work area improving ergonomics and productivity.
