ABSTRACT:
The chin actuated controller system includes a control arm mounted at one end for pivotal movement in both the horizontal and vertical directions and a chin pad supported by the distal end of the control arm which extends to a location adjacent to the chin of a person. The chin pad which includes a chin switch is engageable by the person's chin to cause vertical and horizontal motion of the control arm and forward and reverse and movement of the chin switch. A cam mechanism in combination with a controller electrical circuit is used to convert the chin activated movements of the control arm and chin switch combination to an electrical signal which controls the powered apparatus. The controller electrical circuit also includes additional electrical circuits which provide for electrical switching between the various powered apparatus operations, logic control of the various powered apparatus operations and an audible sound indicating the initiation of the powered apparatus operation selected by the person.
