Systems and Methods for Automatically Adjusting a Power Tool Setting Based on Power Tool Device Positioning Relative to a Work Object
One or more settings of a power tool device can be automatically adjusted based on a location of the power tool device relative to a work object. Work object data that indicate a work object type for the work object can be determined, and work location data can be determined based on the work object data. The work location data indicate work locations on the work object where a power tool device action is to be performed. A position of the power tool device is also determined. An electronic controller can determine a power tool device setting corresponding to the power tool device action to be performed at the work location nearest to the power tool device position. The power tool device setting is transmitted to the power tool device by the electronic controller, where the power tool device setting indicates an operating parameter of the power tool device.

Identifying Power Tool Devices Based on Sound Generated by Electronic Components of the Power Tool Devices
ActiveUS20250153334A1Portable power-driven toolsVibration testingSwitching frequencyElectronic component
A power tool device (102) is controlled to emit sounds that can identify the power tool device and / or be used to encode data for acoustic data transmission. Modulating the switching frequency of electronic components (370) (e.g., transistors, semiconductor switched devices) of the power tool device (102) can create an acoustic signature detectable by a microphone-equipped device (104), such as a cell phone, tablet, security camera, or the like. In this way, power tool identification and / or acoustic data transmission can be realized with existing power tool device circuitry and hardware components.
