    Abstract: A power tool battery charger includes a housing, at least one charging circuit coupled to the housing, and an electronic controller coupled to the housing. The electronic controller is configured to receive power tool device data from a power tool device, which may be the same or another power tool battery charger, a battery pack, and/or a power tool. The power tool device data indicate various data associated with the power tool device. Charger operation data are generated by the electronic controller based on the power tool device data, and can include a charging rate, charging target, and/or time indication for when to adjust the charging rate and/or charging target of the at least one charging circuit. A machine learning or artificial intelligence controller can also be used when generating the charger operation data. The at least one charging circuit is then operated based on the charger operation data.

    Abstract: A power tool including a housing, a trigger, a motor coupled to an output member, and a motor drive circuit coupled to the motor. The power tool further includes a motor controller coupled to the motor drive circuit. The motor control circuit is configured to detect a position change of the trigger, determine one or more parameters associated with the position change, and generate an output based on the one or more determined parameters and a variable trigger mapping function. The output is then output to the motor drive circuit.

    Abstract: Systems and methods for evaluating a crimping application. A power tool includes a pair of jaws configured to crimp a workpiece, a piston cylinder configured to actuate at least one of the pair of jaws, and a pressure sensor configured to provide pressure signals associated with a crimping application. The power tool also includes an electronic processor connected to the pressure sensor. The electronic processor is configured to monitor, while performing the crimping application, a pressure applied by the piston cylinder, construct a pressure curve indicative of a change in the pressure applied during the crimping application, process the pressure curve into a vector indicative of one or more features, evaluate the crimping application based on the vector, and provide an output indicative of the evaluation.

    Abstract: Power tool methods and systems are provided for aligning a power tool to implement an angled cut in a workpiece. The power tool includes a first distance sensor and a second distance sensor. The power tool measures a first distance to the workpiece with the first distance sensor and a second distance to the workpiece with the second distance sensor. The power tool calculates an angle between the power tool and the workpiece based on the first and second distances, and indicates the angle via an angle output indicator of the power tool. The power tool may measure an angle between the power tool and the workpiece using a proximate edge and a distal edge of the workpiece, and indicate whether the power tool maintains a correct angle as it traverses a cut through the workpiece from the proximate edge to the distal edge.

    Abstract: Power tools described herein include a housing, a motor supported by the housing, a battery pack configured to provide electrical power to the power tool, a user input configured to provide an input signal corresponding to a target speed of the motor, a plurality of sensors supported by the housing and configured to generate sensor data indicative of an operational parameter of the power tool, and an electronic controller. The electronic controller includes an electronic processor and a memory. The memory includes a machine learning control program for execution by the electronic processor. The electronic controller is configured to receive the target speed, receive the sensor data, process the sensor data using the machine learning control program, generate, using the machine learning control program, an output based on the sensor data, the output including one or more field weakening parameters, and control the motor based on the generated output.

    Abstract: A tool bit connectable to a tool. The tool bit including a tool body having a working end portion, an insertion end portion, and an outer surface formed on the insertion end portion. The insertion end portion defines an end of the tool body and configured to be coupled to the tool. The tool bit also includes a non-circular profile formed on the tool body and partially defining the outer surface, and an alignment region positioned between the non-circular profile and the end of the tool body. The alignment region partially defines the outer surface to facilitate alignment of the non-circular profile with the tool.
