ABSTRACT:
Orientation sensing apparatus including a bubble suspended in liquid contained within a transparent cylindrical container, light sources aligned along the cylindrical axis of the container that transmit light via light pathways for illuminating the bubble, light sensors disposed along the circumference of the container that receive light via light pathways for measuring the amount of light reflected from the bubble, and signal processing circuitry for converting the light sensors' readings into an orientation indicating signal for communication to other electronic devices.
