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: An arrow rest assembly includes a launcher, a lever, a launcher-lever coupler, and a switch. The launcher moves between launcher-up and launcher-down positions, biased toward launcher-up; the lever moves between brace and drawn positions, biased toward drawn; the coupler moves between coupled and decoupled arrangements, biased toward coupled. When coupled, the launcher and lever move together in an aligned arrangement, including launcher-down with brace and launcher-up with drawn. When decoupled: the launcher and lever move independently, with biased movement of the launcher to launcher-up; and movement of the launcher and lever into the aligned arrangement enables biased movement of the coupler to the coupled arrangement. When coupled and with the lever in the brace position, actuating the switch, using the shaft of an arrow nocked or positioned to be nocked, moves the coupler to the decoupled arrangement and allows biased movement of the launcher to the launcher-up position.
