Gemba Walks are often done in a layered manner. At the lowest layer, the Department Manager does a daily walk, and an hourly associate presents the data. At these daily walks, it is common for the local maintenance mechanics, engineers, and QC technicians to participate.
LIDAR is similar to the radar commonly used to track everything from airplanes in flight to thunderstorms. But instead of bouncing radio waves off its target, LIDAR uses short pulses of laser light. Some of that light reflects off of tiny particles in the atmosphere and back to a telescope aligned with the laser.
Laser Jammers. When your vehicle is hit with the laser of a LIDAR gun, a laser jammer detects the laser and sends out a laser with the same wavelength but higher intensity. This effectively confuses the LIDAR gun, resulting in an inaccurate speed or no speed at all. So you might get around the technology, but laser jammers are easy to detect.
