INGENIEUR COVER FEATURE TECHNOLOGY WATCH DRIVERLESS CAR There are several key players in the making of a driverless car. But Tesla’s electric car with additional software, nicknamed Autopilot, steals the show. The hardware is simple: a camera, bumper-mounted radar, and 12 front-and-rear ultrasonic sensors. The genius is the software which can be updated periodically. The autonomous car gives drivers something similar to what airline pilots employ in flight. It can manage its speed, steer within and even change lanes and park itself. Some of these features, like automatic parallel parking, were already on offer from other car companies, but self-steering via a software, gives the giant leap toward full autonomy. According to Tesla, an updated software called Enhanced Autopilot, expected in December 2016, will add new capabilities such as match speed to traffic conditions, keep within a lane, automatically change lanes without requiring driver input, transition from one freeway to another, exit the freeway when destination is near, self-park when near a parking spot and be summoned to and from a garage. BENDABLE BATTERY A bendable lithium-ion battery that can flex and twist could power future wearable devices, smart watches and flexible smartphones. Although it's still in the early stages of development, the battery has been tested to withstand twists, bends and other deformations while maintaining its ability to hold a charge. Panasonic has announced flexible lithium-ion batteries that are just 0.55mm thick that can be used in card-type or wearable devices. This battery can retain its charge and characteristics even when flexed by an angle of 25° or twisted to a radius of 25mm. 6 16 VOL - DECEMBER 2016 VOL68 55OCTOBER JUNE 2013
