A line scanner assembly includes a cam with a cam surface, where the cam rotatable about a cam axis of rotation and includes a first ferromagnetic material. A mirror with a planar surface is configured to tilt about a mirror axis of rotation. A follower is attached to the mirror and has a second ferromagnetic material, where the first magnetic material and/or the second magnetic material includes a permanent magnet and where the follower maintains contact with the cam due to a magnetic attraction between the first ferromagnetic material and the second ferromagnetic material.

A one or more plane, variable camshaft is described. The single plane camshaft includes a circular drive plate with two radial drive slots on opposing sides of the center, four arms movably coupled at respective endpoints and arranged in a polar configuration, and a scroll plate to allow adjustable operation of the camshaft. Multiple plane camshafts may include a number of half drive plates arranged around a drive block and secured to a base washer through a scroll block. The variable camshaft may be incorporated into portable, motorized or manual, bag valve mask based resuscitation devices or similar ones.
