With people at the wheel ever more susceptible to distractions, drowsiness and impairment, driver monitoring systems (DMS) are considered key in accident prevention. But are we overdesigning the sensors at the heart of these systems? Simulations using a new sensor modeling tool and a deep neural network (DNN) indicate it is plausible that we are—by … Read more
The battery is the costliest element in an electric vehicle (EV), making battery management system (BMS) a key design recipe in vehicle electrification. Not surprisingly, therefore, BMS requirements are growing as EVs go mainstream. So, in a bid to improve battery performance and enable new applications, semiconductor suppliers are joining hands with automotive software specialists … Read more

When applied to pharmaceuticals, the term “off-label” suggests the (frequently discovered) practical and beneficial uses for a drug that are different from the one it was originally developed for. This happens for electronic components too, such as the venerable CD4013B dual-D CMOS flip-flop. Despite the 4013’s labeling as a traditional bi-stable logic element, it nevertheless … Read more
