What this episode covers

Elecia White explains the physics and engineering of inertial sensors, distinguishing between MEMS accelerometers (which measure static gravity/tilt) and rate sensors (which measure angular velocity). She details how to combine these with magnetometers and GPS using Kalman filters to estimate orientation (roll, pitch, yaw) and position, while highlighting challenges like temperature compensation and sensor mounting.

    Conversation with IEEE Medal of Honor Recipient Asad Madni

    Asad Madni, the 2022 IEEE Medal of Honor recipient, discusses his pioneering development of the first microelectromechanical systems (MEMS) gyroscope and inertial measurement unit. He explains how this quartz-based sensor technology transitioned from aerospace and defense applications to the automotive industry, where it became critical for electronic stability control and rollover prevention in vehicles from manufacturers like General Motors and Continental. Madni also details the company's work on high-resolution optical encoders for the Hubble Space Telescope and offers his perspective on the future of artificial intelligence in scientific discovery.
