The man who brought fail-safe brakes to railroads once had a major role in the 20th-century industry, but a combination of events and decisions have left only his braking system as a recognized legacy. Part 1 established the need for a reliable, fail-safe braking system. This part looks at the system design in more detail, […]

Westinghouse and the fail-safe train air brake, Part 1: The problem
The man who brought fail-safe brakes to railroads once had a major role in the 20th-century industry, but a combination of events and decisions have left only his braking system as a recognized legacy. Some innovations seem so obvious and pervasive that we assume they have always been with us, but, of course, that is […]
Energy harvesting applications considerations – Virtual Roundtable (part 2 of 2)

Joining us for this virtual roundtable are: Dr. André Mansano (AM), CTO at Nowi; Graeme Clark (GC), Marketing Manager, Energy Harvesting Business Unit, at Renesas Electronics, Ken Imai (KI) Sr. Manager, Product […]
Design challenges when using energy harvesting – Virtual Roundtable (part 1 of 2)
The first part of EEWorld’s two-part “virtual roundtable” discussion on energy harvesting considers technical challenges and design tradeoffs for engineers using energy harvesting power sources. Joining us for this virtual roundtable are: Dr. André Mansano (AM), CTO at Nowi; Graeme Clark (GC), Marketing Manager, Energy Harvesting Business Unit, at Renesas Electronics, Ken Imai (KI) Sr. […]
Protecting autonomous vehicle control circuits
The subsystems that make up an autonomous vehicle should be bullet-proof when it comes to electrical interference and transients. James Colby, Prasad Tawade Littelfuse, Inc. Those who follow autonomous vehicle technology are usually well aware of its benefits. But the safety and convenience autonomous vehicles offer can only come if the vehicle electronics is reliable […]
Optimizing in-vehicle data networks
Physical channels have limits that affect the practicalities of automotive network architecture and communication protocols. Here’s the lowdown on current work aimed at breaking bandwidth bottlenecks. CHRIS RUSCH, BERT BERGNER | TE Connectivity It has become a truism that we have an insatiable appetite for data. Not so obvious is the effect our need for […]
The sense-think-act model of autonomous vehicles
Electronics and software tend to be more important than the mechanics of autonomous vehicles. This shift has serious implications for how vehicles are designed. Puneet Sinha | Mechanical Analysis Div., Mentor, a Siemens business Though certain autonomous functions, especially driver-assist and active-safety features, have started to show up in some recent-model vehicles, the goal of […]
Open standards for driverless cars
Why unsafe autonomous vehicle systems are passing undetected during development. Dr. Luca Castignani, MSC Software In February, McAfee exposed the alarming gap between the road test and real-world performance of autonomous vehicle sensors. In a demonstration, McAfee was able to fool a Tesla car into accelerating to 85 mph in a 35 mph zone using […]
OEM guide to ADAS development
As automotive electronics becomes more complex, the quest is on for economical ways to cover the widest possible range of requirements. Eric Pinton | Renesas Electronics In recent years, few topics have stoked the automotive industry’s collective enthusiasm like autonomous vehicles. Pushed by widely publicized breakthroughs in connected vehicle development, deep learning software, and data-driven […]
Safety and cyber security for the connected car
Even the best coding practices are likely to result in vehicles infected with 10,000 software bugs. Simulated attacks can sniff out vulnerabilities before the car hits the road. Hwee Yng Yeo, Rick Kundi | Keysight Technologies The era of the connected car, and a growing concern over cybersecurity threats, is here. Safeguarding the connected car […]
