Global navigation satellite systems (GNSS) are vital for positioning autonomous vehicles, buses, drones, and outdoor robots. Yet its accuracy often degrades in dense urban areas due to signal blockage ...
Abstract: To accomplish ultraprecise noncontact scanning of freeform, this article proposes a technique for measuring normal vectors (NVs) using differential confocal absolute position triggering ...
Abstract: The back electromotive force (back-EMF) method, based on detecting zero-crossing points of back-EMF, is a widely used technique for sensorless brushless DC ...
