Abstract: A power tool and method for recording and playing back a motor parameter. The power tool includes a housing, a motor, a trigger, and a controller. The trigger outputs an activation signal based on a user input. The controller receives a user mode selection signal indicating a selected mode. The controller enters the recording mode when the user mode selection indicates the recording mode, and records a motor parameter to generate a recorded motor parameter. The recorded motor parameter covers a first time period in which motor is operating in response to depression of the trigger, a second time period in which motor is inactive in response to release of the trigger, and a third time period in which motor is operating in response to another depression of the trigger. In the playback mode, the controller operates the motor based on the recorded motor parameter upon receiving the activation signal.

Abstract: A geodetic surveying instrument to move a measurement light beam into a desired measurement direction in space, comprising at least one movement axis which is motorized, providing a positioning of the measurement direction of the geodetic surveying instrument, and an instrument-encoder at the movement axis configured for deriving the measurement direction as a measurement value of the geodetic surveying instrument. The geodetic surveying instrument comprises a transmission link of the movement axis of the geodetic surveying instrument to a motor axis of a stepper motor, which transmission link is configured with a gear reduction and a slipping clutch arrangement, and wherein the stepper motor comprises a rotational motor-encoder on its motor-axis and is driven by a motor controller that provides a field oriented control of phase currents of the stepper motor, which field orientation is derived based on the rotational motor-encoder.

Abstract: A power tool including a sensor attachment, a housing, a motor, and a power tool controller. The power tool controller is operable or configured to control power provided to the motor. The sensor attachment is coupled to the power tool's housing and includes a first non-contact sensor and a sensor controller. The sensor controller receives signals from the first non-contact sensor related to distance to a work surface and determines a fastener depth based on the signals from the first non-contact sensor. If the fastener depth is greater than or equal to a desired fastener depth, the sensor controller generates and sends a control signal to the power tool controller. In response, the power tool controller turns off or cuts power to the motor.

Abstract: A power tool may include an end effector configured to enable a fastener to be applied by the power tool via a fastening cycle, a power unit, a drive assembly configured to apply drive power to the end effector responsive to application of input power thereto, and a motor configured to supply the input power to the drive assembly selectively based on operation of a power control assembly that controls coupling of the motor to the power unit. The drive assembly includes a clutch configured to interrupt application of the drive power at a target torque. The power control assembly may be configured to adaptively change speed of the motor in response to the power tool reaching a predefined torque value that is less than the target torque during the fastening cycle.

Abstract: Systems and methods of operating power tools. The method includes receiving a command to start a recording mode at a first electronic processor of a first power tool, and receiving at the first electronic processor, a measured parameter from a sensor of the first power tool while a first motor of the first power tool is operating. The method also includes generating a recorded motor parameter by recording the measured parameter, on a first memory of the first power tool, when the first power tool operates in the recording mode, and transmitting, with a first transceiver of the first power tool, the recorded motor parameter. The method further includes receiving the recorded motor parameter at an external device, transmitting the recorded motor parameter to a second power tool via the external device, and receiving the recorded motor parameter via a second transceiver of the second power tool.
