Patent ID: 8376570

Claim:
A portable illumination system comprising: a distal member including an exterior surface with a plurality of radially separated tactile indicators including a distal activated indicator and a distal deactivated indicator; a proximal member including an exterior surface with a plurality of radially separated tactile indicators including a proximal activated indicator and a proximal deactivated indicator, wherein the proximal member is rotatably coupled to the distal member, and wherein the rotatable coupling between the members includes resistive rotational feedback across a plurality of independent rotational regions between the members corresponding to a linear alignment between the distal activated indicator and the activated proximal indicator; an electrical power source; an electro-optical output device; a rotational switching mechanism configured to switch between an activated state and a deactivated state, wherein the activated state includes an electrical coupling between the electrical power source and the electro-optical output device across a plurality of independent rotational regions between the members corresponding to a linear alignment between the distal activated indicator and the activated proximal indicator.
