The fundamental technology that these companies rely on is not new: Electroencephalography (EEG) has been around for about a century, and it’s commonly used today in both medicine and neuroscience research. For those applications, the subject may have up to 256 electrodes attached to their scalp with conductive gel to record electrical signals from neurons… Continue reading The EV Transition Explained: Battery Challenges

Industrial Functional Safety Training from UL Solutions
As Verne understood, the U.S. Civil War (during which 60,000 amputations were performed) inaugurated the modern prosthetics era in the United States, thanks to federal funding and a wave of design patents filed by entrepreneurial prosthetists. The two World Wars solidified the for-profit prosthetics industry in both the United States and Western Europe, and the… Continue reading Industrial Functional Safety Training from UL Solutions
The EV Transition Explained
Why not? EVs lack tailpipe emissions, sure, but producing, operating, and disposing of these vehicles creates greenhouse-gas emissions and other environmental burdens. Driving an EV pushes these problems upstream, to the factory where the vehicle is made and beyond, as well as to the power plant where the electricity is generated. The entire life cycle… Continue reading The EV Transition Explained
Crowdsourcing Bridge Inspection
Apps that tap into smartphone sensors to monitor human health and diagnose diseases abound. Now, engineers have come up with a way to use smartphone data to reveal if bridges are ailing, allowing repairs before they fail. Using such crowdsourced data as part of maintenance could increase a new bridge’s lifespan by over fourteen years… Continue reading Crowdsourcing Bridge Inspection
Solving Automotive Design Challenges With Simulation
The development of new hybrid and battery electric vehicles introduces numerous design challenges. Many of these challenges are static or low-frequency electromagnetic by nature, as the devices involved in such designs are much smaller than the operating wavelength. Examples include sensors (such as MEMS sensors), transformers, and motors. Many of these challenges include multiple physics.… Continue reading Solving Automotive Design Challenges With Simulation
Chopper Rocket Chasers Played “Catch Me if You Can”
Update 4 Nov. 2:45 p.m. EDT:Rocket Lab says its launch was successful, but booster recovery was not. It says it lost telemetry signals from the descending first stage during reentry. “As standard procedure, we pull the helicopter from the recovery zone if this happens,” a company spokesperson said. “If at first you don’t succeed….” Rocket… Continue reading Chopper Rocket Chasers Played “Catch Me if You Can”
Fast-Charging EV Batteries With Nickel Foil
Utrecht, a largely bicycle-propelled city of 350,000 just south of Amsterdam, has become a proving ground for the bidirectional-charging techniques that have the rapt interest of automakers, engineers, city managers, and power utilities the world over. This initiative is taking place in an environment where everyday citizens want to travel without causing emissions and are… Continue reading Fast-Charging EV Batteries With Nickel Foil
Autonomous Vehicles: Ensuring No Data Is Lost in Transmission
As the automotive industry navigates a new era of self-driving cars, every second matters. The information obtained from sensors and electronics must be given to the main CPU as precisely and quickly as possible. To ensure optimal safety and performance, it’s imperative that no data is lost in transmission. To achieve this, we’re increasingly relying… Continue reading Autonomous Vehicles: Ensuring No Data Is Lost in Transmission
