Abstract
A method and apparatus for determining a rotational orientation of an object is provided. Embodiments of the present invention utilize an electrically conductive fluid enclosed within a shell attached to the object such that the conductive fluid contacts different portions of electrically conductive nodes, located on the inner wall of the shell, depending on the rotational orientation of the shell. The electrically activated nodes in contact with the conductive fluid act as sensors and individually transmit electric signals to a microcontroller for transformation into an indicator of a rotational orientation of the object. The indicator of the rotational orientation is then output.
