Abstract: A rotary hammer operable in a plurality of modes in which reciprocating of a tool bit along a drive axis and/or rotation of the tool bit about the drive axis occurs. The rotary hammer includes a trigger, a mode switch, a motor direction switch, and a control unit. The trigger is movable between off and on positions. The mode switch selects a mode of operation between first and second operating modes. The motor direction switch is configured to select a direction of operation of a motor between first and second rotational directions. A control unit is configured to override an output of the motor direction switch by determining that the mode switch corresponds with the second operating mode, determining that the motor direction switch corresponds with the first rotational direction, and by driving the motor in the second rotational direction upon actuation of the trigger.

Abstract: A power tool includes a housing, a motor, a switching network electrically coupled to the motor, and a printed circuit board positioned at an angle within the housing. The power tool further includes a user input configured to receive a sensitivity level for loss of control detection, a sensor configured to measure an acceleration of the housing with respect to at least two axes, and an electronic processor coupled to the switching network. The electronic processor is configured to receive one or more signals related to the acceleration of the housing of the power tool from the acceleration sensor, determine that the one or more signals exceed an acceleration threshold corresponding to the sensitivity level for loss of control detection, and control the switching network to brake the brushless DC motor in response to the one or more signals exceeding the acceleration threshold.

Abstract: A wireless hoist system including a first hoist device having a first motor and a first wireless transceiver and a second hoist device having a second motor and a second wireless transceiver. The wireless hoist system includes a controller in wireless communication with the first wireless transceiver and the second wireless. The controller is configured to receive a user input and determine a first operation parameter and a second operation parameter based on the user input. The controller is also configured to provide, wirelessly, a first control signal indicative of the first operation parameter to the first hoist device and provide, wirelessly, a second control signal indicative of the second operation parameter to the second hoist device. The first hoist device operates based on the first control signal and the second hoist device operates based on the second control signal.

Abstract: A printed circuit board assembly for use in a power tool includes a potting boat, a printed circuit board, a thermally conductive gap pad, potting material, and a secondary heat sink. The potting boat includes primary heat sink fins. The electronic components are mounted on a first surface of the printed circuit board. The gap pad contacts the electronic component and the stand-off. The potting material at least partially encapsulates the printed circuit board within the potting boat. The secondary heat sink contacts a second surface of the printed circuit board opposite the first surface. The secondary heat sink includes secondary heat sink fins. Heat generated by the electronic components is transferred via conduction to both the primary heat sink fins and the secondary heat sink fins. The heat is dissipated to the surroundings of the printed circuit board assembly.

Abstract: A walk-behind lawnmower includes a mower deck, a plurality of wheels coupled to the mower deck, a drive motor configured to operate at a drive speed to drive at least one of the plurality of wheels, and a handle coupled to the mower deck. The handle includes a user interface having a variable speed control configured to be actuated an actuation percentage, and a maximum speed control including a setting corresponding to a maximum mower speed. The drive speed of the drive motor is determined using the actuation percentage of the variable speed control scaled by the setting of the maximum speed control.
