Google is working on a technology that would help its self-driving car sensors identify emergency vehicles, according to a newly published patent application. At the core of the technology is the ability for a car to identify a set of lights and determine whether they are emergency vehicles or not, according to the patent.

If you have been watching the famous space series “Star Trek”, you would be familiar with a device called The Tricorder, which is a science-fictional handheld device that is used to scan sensors and analyze and record data. As far as the medical tricorder, it might not be fictional anymore, it might become a reality and an important part of every astronaut’s arsenal very soon.
