Abstract
The present disclosure is directed to kickback detection for devices, such as handheld drills. Kickback is detected using a gyroscope and an accelerometer, and is detected at the end of each of a plurality of time windows. At the end of each time window, kickback is detected based on, for example, a variance of a norm of gyroscope measurements. False kickback detections are then removed based on, for example, a minimum and a mean of accelerometer measurements. Kickback detection is completed before the next time window begins.
