Abstract
An two-way optical communication apparatus, including a transmit element, a receive element, and a transceive processor. The transmit element is coupled to a light pipe, and transmits a first signal. The receive element is coupled to the light pipe, and receives a second signal. The transceive processor directs the transmit element to pause and then resume transmitting the first signal during first intervals, and directs the receive element to sample for the second signal during one or more second intervals within each of the first intervals, where the each of the first intervals is less than a first value and the first intervals occur at a duty cycle no greater than a second value, and where the first and second values are controlled by the transceive processor such that a user perceives the first optical signal as having a constant state for a third interval.
