Identifying Power Tool Devices Based on Sound Generated by Electronic Components of the Power Tool Devices

Abstract: a power tool device () 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 () (e.g., transistors, semiconductor switched devices) of the power tool device () can create an acoustic signature detectable by a microphone-equipped device (), 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.
