Abstract
A method for resolving blind spots associated with a proximity sensor provides an optical guide in cooperation with an isolator wall that separates a transmitting section and a receiving section of the proximity sensor. Additionally, a specific guide angle of the optical guide directs, towards a receiver, more light rays reflected off an external object than light rays transmitted from a light source in the transmitting section.
