Abstract: A lifting device includes a base, a mast coupled to the base, a carriage coupled to the mast, and a lifting assembly configured to move the mast and carriage in a first direction to a desired elevation relative to the base. The lifting device includes an electric motor, a battery pack for providing electrical power to the electric motor and a spool with a cable to alternately raise and lower the carriage in the first direction. The lifting device includes means for detecting a weight and/or a center of gravity of a load to be lifted by the lifting device, and a user interface operable to communicate information about the weight and/or the center of gravity of the load to a user of the lifting device.

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 concrete vibrator system comprises a vibrating head including a shaft. The shaft has a center of mass that is radially offset from a rotational axis of the shaft. The vibrating head also includes an onboard electric motor configured to provide torque to the shaft, causing the shaft to rotate. The concrete vibrator system further comprises a portable power unit including a battery pack configured to provide electrical current to the motor. A cable extends between the portable power unit and the vibrating head. The cable is configured to transmit electrical current from the battery pack to the motor and a motor control signal from the portable power unit to the motor.

Abstract: A cable puller has a frame, a capstan rotatably mounted on the frame, a motor which drives the capstan to rotate, a power supply which supplies electrical current to the motor, a transmission which transfers torque from the motor to the capstan, a display mounted to the frame, a sensor operable to generate a signal, and a controller. The transmission can operate in a low-speed configuration and a high-speed configuration. The controller is electrically coupled to the motor, the power supply, and the display. The controller includes computer executable instructions stored in a computer readable medium for controlling operation of the cable puller to receive the signal from the sensor, determine a torque of the capstan based on the signal, determine a tension of a cable being pulled based on the torque of the capstan, and generate a control signal when the tension of the cable approaches a predetermined tension.

Abstract: A portable power unit comprises a battery pack interface configured to receive a battery pack and a power tool interface that is configured to electrically connect to an external power tool. The portable power unit further comprises a tool control circuit configured to generate a tool control signal. The tool control signal is operable to control power provided to the external power tool. The portable power unit further comprises a bypass circuit configured to provide power from the battery pack to the external power tool. The portable power unit further comprises a controller configured to determine whether the external power tool is operable to be controlled by the tool control circuit and to control the bypass circuit to provide passthrough power to the power tool interface when the external power tool is not operable to be controlled by the tool control circuit.
