There is an opening to the internal region formed along at least a portion of a perimeter of the aperture and there is a light source disposed in the internal region. The light source is directed toward the opening to allow the light source to illuminate charge connector.

A power tool includes a power mechanism including a drive shaft; an oscillating mechanism; an airflow element connected to the drive shaft; a heat conducting portion supported on the drive shaft, where the airflow element is disposed on the heat conducting portion. The oscillating mechanism includes a support assembly sleeved on the drive shaft and an oscillating member. Heat generated by the oscillating mechanism is conducted to the heat conducting portion through the drive shaft, the heat conducting portion has a thermal conductivity greater than or equal to 50 W/m•°C, and a ratio of an axial distance L1 of a portion of the heat conducting portion in contact with the drive shaft to a distance L2 of a thermally conductive portion of the drive shaft between the heat conducting portion and the support assembly is greater than or equal to 0.1 and less than or equal to 5.

A target illuminating stapling device for safely fastening an item to a substrate includes a staple gun and a bulb. The staple gun comprises a staple driver, a handle, and a staple cartridge. The staple driver is positioned in a front portion of the staple gun. The handle is hingedly engaged to the front portion and extends over a back portion of the staple gun. The handle is operationally engaged to the staple driver. Levering of the handle actuates the staple driver to fasten a staple into a substrate. An item that is positioned between the staple and the substrate is fastened to the substrate. The staple cartridge selectively feeds the staple to the staple driver. The bulb is engaged to the staple gun proximate to the staple driver. The bulb selectively illuminates a target area of the substrate into which the staple is to be fastened.

A device for ascertaining the orientation of a drill relative to a plane, the device being capable of being connected to the drill, the device having a laser distance measuring unit by which, from a prespecified position relative to the plane, a first distance to a first point in the plane and a second distance to a second point in the plane can be measured, and having an evaluation unit that is configured such that on the basis of the first distance and the second distance the orientation of the device relative to the plane can be ascertained.

A motor driven appliance in one aspect of embodiments of the present disclosure comprises a light source, a lighting unit, a motor, an operation unit, an operation detector, a reference signal output unit, a determination unit, and a control unit. The operation detector detects that the operation unit is operated, and outputs an operation detection signal that indicates that the operation unit is operated. The reference signal output unit outputs at least one reference signal that can be used as a reference for determining whether the detection by the operation detector is normal. The determination unit determines whether the operation unit is actually operated based on the operation detection signal and the at least one reference signal. The control unit controls operation of the lighting unit based on the determination made by the determination unit.
