Abstract: Braking a power tool motor based on a phase voltage of the motor. The power tool includes a motor and a power source providing operating power to the motor. A power switching network is between the power source and the motor to drive the motor. An actuator is operable to provide an input. An electronic controller is connected to the actuator and the power switching network. The electronic controller is configured to receive an indication related to initiating braking of the motor, control the power switching network to allow the motor to coast, monitor a phase voltage of the motor, determine whether the phase voltage of the motor is equal to or less than a phase voltage threshold, and control, in response to the phase voltage of the motor being equal to or less than the phase voltage threshold, the power switching network to brake the motor.

Abstract: At least first and second rows of panels may be mounted onto, or to form, at least part of a pitched roof, wall or other structure by mounting a panel support framework onto an underlying structure and arranging the panels so that each panel on the second row is offset upwardly relative to each panel on the first row in a stepped fashion.

Abstract: A connector includes a flexible connector having a first plurality of solder bumps arranged in a first pattern, and a base connector having a second plurality of solder bumps arranged in a second pattern concentric with and of a different size than the first pattern. A method of interconnecting a flexible connector to a base connector includes providing the flexible connector with a first plurality of solder bumps arranged in a first pattern, and providing the base connector with a second plurality of solder bumps arranged in a second pattern. The flexible and base connectors are aligned by aligning the first and second pluralities of solder bumps.
