Abstract: An impact tool includes a housing that includes a motor housing portion, a front housing portion coupled to the motor housing portion, and a D-shaped handle portion extending from the motor housing portion in a direction opposite the front housing portion. The impact tool includes an electric motor supported in the motor housing portion, a battery pack supported by the housing for providing power to the motor, and a drive assembly for converting a continuous torque input from the motor to consecutive rotational impacts upon a workpiece capable of developing at least 1,700 ft-lbs of fastening torque.

Abstract: A power tool and a printed circuit board assembly (“PCBA”) for the power tool. The PCBA includes, for example, a printed circuit board (“PCB”), a heat sink, a spacer between the PCB and the heat sink, and a gap pad. The PCB and the heat sink are fastened to one another via fasteners so the spacer absorbs excess forces torsional forces from torques applied to the fasteners. The gap pad is placed within an opening or recess of the spacer to contact one or more FETs on the PCB. In some embodiments, the PCBA includes a second heat sink or rigid member on the opposite side of the PCB than the spacer to further distribute excess torsional forces from torques applied to the fasteners.

Abstract: A potting boat adapted to receive a printed circuit board is described. The boning boat includes a base plate and a plurality of sidewalls projecting from the base plate, a plurality of cooling fins, a recessed portion, and an arm. The plurality of cooling fins are formed on one of the sidewalls. The cooling fins extend laterally outward from the one of the sidewalls. The recessed portion is in a first sidewall of the plurality of sidewalls, and extends laterally inward. The arm has a first end fixed to the sidewall and an opposite, second end not connected with the first sidewall. The arm at least partially overlays the recessed portion to define a void within which electrical wires connected to the printed circuit board are retained proximate the first sidewall.

Abstract: A power tool device that includes a housing, a battery pack interface configured to receive at least one battery pack, a first battery pack terminal and a second battery pack terminal, a low quiescent current direct current (“DC”) link bus discharge circuit including a DC link bus capacitance, a first DC link bus switch, and a second DC link bus switch, and a controller. The controller is configured to monitor a voltage of the first battery pack terminal, monitor a voltage of the second battery pack terminal, turn ON the first DC link bus switch and the second DC link bus switch when the voltage of the first battery pack terminal is greater than a first threshold value and the voltage of the second battery pack terminal is zero volts.

Abstract: A battery powered lawnmower having a blade motor coupled to at least one blade, a user input device configured to receive a blade motor control signal and a bail control bar. The bail control bar is coupled to a position sensor configured to determine a position of the bail control bar. The battery powered lawnmower further includes a controller coupled to the position sensor and configured to control an operation of the blade motor. The controller is configured to receive a blade motor control command and determine a position of the bail control bar based on data provided by the position sensor. The controller is further configured to, in response to determining that the bail control bar is in a closed position, control the blade motor based on the received blade motor control command.

Abstract: A lawnmower may include an inertial measurement device configured to capture data indicative of an orientation of a housing of the lawnmower. The lawnmower may also include a controller coupled (i) to a motor configured to rotate one or more cutting blades and (ii) to the inertial measurement device. The controller may be configured to receive, from the inertial measurement device, the data indicative of the orientation of the housing. The controller may be further configured to determine a three-dimensional position of the housing based on the data. The three-dimensional position of the housing may indicate whether the orientation of the housing is desirable for operation of the lawnmower. The controller may be further configured to control the motor based on the three-dimensional position of the housing.
