And yet even now, after 150 years of development, the sound we hear from even a high-end audio system falls far short of what we hear when we are physically present at a live music performance. At such an event, we are in a natural sound field and can readily perceive that the sounds of… Continue reading The Best Tech of CES 2023

BMW’s iVision Dee Brings Sci-Fi to the Driveway
Before I met BMW’s iVision Dee at a press preview event in Germany— prior to a public reveal at CES in Las Vegas last week—I’d never seen a car blush, let alone had one make me blush. But then the electric BMW began changing colors and facial expressions, talking at me in intimate detail, splashing… Continue reading BMW’s iVision Dee Brings Sci-Fi to the Driveway
The EV Transition Explained: Policy Roadblocks
“Public policy implementation is hard even if everyone supports a policy,” says University of Michiganprofessor emeritus John Leslie King, who has studied policy management and administration for decades. It becomes infinitely harder when the technology is complex and depends on several other equally complex technologies; where the stakes are huge; where there is a myriad… Continue reading The EV Transition Explained: Policy Roadblocks
Electromagnetic Modeling and Design of an Actuator
An electromagnetic actuator is a device that converts electrical energy into mechanical energy in the form of linear or rotational motion. The motion can be used, for example, to vibrate a speaker diaphragm, open and close an electromagnetic valve, or open and close an electromagnetic relay. A typical electromagnetic actuator consists of various components including… Continue reading Electromagnetic Modeling and Design of an Actuator
The EV Transition Explained: How to Meet Sales Targets?
With less than eight years for the United States to meet the objective of a 50-percent reduction in greenhouse gas emissions, many environmental advocacy groups argue that an even faster transition to EVs is mandatory. For instance, the Rocky Mountain Institute (RMI) estimates that 1-in-4 light-duty vehicles, or about 70 million EVs, must be on… Continue reading The EV Transition Explained: How to Meet Sales Targets?
Electric Drivetrain Evolution: From Past to Future
Download this poster to get an overview of eDrivetrain developments and how to test them. By 2035 most industrial countries will ban the sales of new combustion engine vehicles, necessitating the development of electric vehicles from today’s status to become affordable for the mass market with equivalent or superior performance to conventional vehicles. Developers must… Continue reading Electric Drivetrain Evolution: From Past to Future
The EV Transition Explained: Local Policies Shape Global Competition
The Biden Administration is very clear in what it desires to achieve with its environmental policy: a complete transformation of the $21 trillion U.S. economy away from fossil fuels. The Administration is undertaking multiple actions to place the United States on what it calls an “irreversible path” to achieve a 50-52 percent reduction in greenhouse… Continue reading The EV Transition Explained: Local Policies Shape Global Competition

3 Ways to Help NASA’s All-Electric Aircraft Take Off
This article is part of our exclusive IEEE Journal Watch series in partnership with IEEE Xplore. The race for all-electric planes is underway, and some early designs are making headlines. This past September, a prototype of the Eviation Alice completed an 8-minute maiden flight, and more models, such as Heart Aerospace’s ES-30, are anticipated to… Continue reading 3 Ways to Help NASA’s All-Electric Aircraft Take Off
Where Power Meets the Road
Rohde & Schwarz, the only supplier of fast diode sensors for power measurements up to 67 GHz, is increasing the maximum measurable frequency of diode power sensors to 90 GHz, higher than any other diode sensor currently available. The diode technology enables extremely fast and accurate power measurements with the highest sensitivity from a compact… Continue reading Where Power Meets the Road
