The invention relates to an actuator mechanism for adjusting at least one angular position of a mirror element in an exterior mirror device for a motor vehicle. The actuator mechanism comprises a base element and a mirror element movably coupled with the base element, which comprises a mirror support for supporting a mirror surface. The mirror element is rotatable relative to the base element about at least a first pivoting axis with the aid of a first electric motor provided in the actuator mechanism, which extends in a longitudinal direction that is substantially transverse to a supporting surface of the mirror support. What can be elegantly facilitated by this, for instance also in the case of a relatively small mirror surface that is only a few centimeters wide and/or is only a few centimeters long, is that, as seen from a direction in which during use the mirror surface is being viewed by a driver, such electric motor does not protrude, or hardly protrudes, next to, above and/or below the mirror surface.

A toothbrush includes a removable, replaceable brush head that includes a clip that also serves as a removal tool for a spent brush head. The toothbrush may be a manually-wound or charged, powered toothbrush that includes a winding mechanism, an energy storage element, and an output gear train to cause a rotating, oscillating or sweeping brush head to move, thus improving the efficacy of the user's oral-care regimen.

A balanced motorcycle powertrain is described. Embodiments of the balanced motorcycle powertrain include components mounted to a frame of a motorcycle such that the powertrain can be evenly balanced about a centerline of the frame. The balanced motorcycle powertrain can include, but is not limited to, a motor, a transmission, a pair of clutches, a clutch shaft, a crank shaft, a pair of superchargers, a pair of chains, a pair of rear sprockets, and a rear wheel. Each of the components can be oriented such that the powertrain is substantially balanced about the centerline of the frame.
