A recently granted patent (Publication Number: US11752586B2) describes a power tool with advanced features for measuring and indicating drive depth. The power tool includes a chuck for securing a tool and a motor that rotates the chuck and the tool. It also features multiple position sensors that measure the distance between the sensors and the workpiece, generating corresponding signals.

The power tool's controller is responsible for storing previously measured distances and comparing them with current measurements. It calculates the percent difference between the current and stored distances and retains the measurements only if the percent difference is within a threshold percentage. Additionally, the controller can cause the position sensors to project a blinking pattern that conveys a warning message to the user.

The controller uses the signals from the position sensors to determine the drive depth of the tool into the workpiece. As each predetermined interval of drive depth is reached, the controller generates an indication of drive depth. This indication can be conveyed through various means, including haptic buzz, audible beep, visual illumination, or a consistent indication. The controller can also vary the indication as different predetermined intervals of drive depth are reached.

Furthermore, the power tool can include a third position sensor to provide additional data for determining the drive depth. The controller incorporates the signals from the third position sensor in its measurement calculations. It can discard any distance that is less than the distance between the respective position sensor and the distal end of the chuck. The remaining distances are then used to determine the measurement of drive depth.

In addition to measuring drive depth, the power tool's controller can determine the angle of the tool with respect to the workpiece. It generates signals that cause a display device to present the angle of the tool, providing the user with valuable information.

Overall, this patented power tool offers advanced drive depth measurement capabilities and various indications to assist users in achieving accurate and consistent results. The combination of position sensors, a controller, and different signaling methods enhances the tool's functionality and usability.
