    Abstract: An electrical device including a first battery pack receptacle, a second battery pack receptacle, and circuitry including an electronic processor. The first battery pack receptacle is configured to receive a first battery pack. The second battery pack receptacle is configured to receive a second battery pack. The second battery pack is electrically connected in a series-type configuration with the first battery pack. The circuitry is configured to alter a first signal output from the electronic processor to at least one selected from a group consisting of the first battery pack and the second battery pack, and alter a second signal received by the electronic processor from at least one selected from the group consisting of the first battery pack and the second battery pack.

    Abstract: An expanding tool comprising: an actuator comprising a cylindrical housing that defines an actuator housing cavity; a primary ram disposed within the actuator housing cavity, the primary ram defining an internal primary ram cavity; a secondary ram disposed within the internal primary ram cavity; a cam roller carrier coupled to a distal end of the secondary ram; a drive collar positioned within a distal end of the actuator housing cavity; a roller clutch disposed within an internal cavity defined by an inner surface of the drive collar; a shuttle cam positioned between the roller clutch and a distal end of the primary ram; an expander cone coupled to the primary ram; and an expander head operably coupled to the drive collar. When triggered, the actuator first rotates the expander head and then the actuator expands the expander head.

    Abstract: A power tool system includes a hydraulic power tool. The hydraulic power tool includes a hydraulic drive, a sensor, and a first electronic processor. The sensor is configured to detect an operational parameter of the hydraulic drive during an operation by the hydraulic drive. The first electronic processor is configured to store a plurality of data points based on the operational parameter detected during the operation and send the plurality of data points to an external device. The external device includes a display screen and a second electronic processor configured to receive the plurality of data points from the hydraulic power tool, control the display screen to display an expected data point for the operational parameter for the operation, and control the display screen to display an actual data curve based on the plurality of data points, the actual data curve overlaid on the expected data point.

    Abstract: A power tool includes a three-phase DC motor, a power switching network, a power source, and an electronic processor. A first phase of the motor is connected between a first low side electronic switch and a power source electronic switch, and connected to the power source via a first high side electronic switch in parallel with a diode. The electronic processor is configured to receive an indication to stop the motor during operation of the motor and activate the first low side electronic switch and a second low side electronic switch for a first predetermined time responsive to receiving the indication such that a back-electromagnetic force generated by the motor is stored in the first phase. The electronic processor is configured to deactivate the second low side electronic switch after the first predetermined time such that a first regenerative current is provided to the power source via the diode.

    Abstract: Methods and power tools for sensorless motor control. One embodiment provides a method for automatic control switching for driving a sensorless motor (150) of a power tool (100). The method includes determining, using a motor controller (224), a first load point based on user inputs (232) and determining, using the motor controller (224), a first motor control technique corresponding to the first load point. The method also includes driving the motor (150) based on the first motor control technique. The method further includes determining, using the motor controller (224), a change from the first load point to a second load point and determining, using the motor controller (224), a second motor control technique corresponding to the second load point. The method includes driving the motor (150) based on the second motor control technique.
