Abstract
The present invention is directed, in part, to a receiver for an infrared light source. The receiver comprises a substantially transparent body; a sensor for receiving infrared light; and a substantially planar first surface on the transparent body. The first surface is configured to direct light from the infrared light source to the sensor. The substantially planar first surface comprises the end of the substantially transparent body. The substantially planar first surface provides an internally reflective surface that directs light into the interior of the substantially transparent body so it will make contact with the sensor.

A receiver for an infrared light source, the receiver comprising:
- a substantially transparent body;
- a sensor for receiving infrared light;
- and
- a substantially planar first surface on the transparent body, the first surface configured to direct light from the infrared light source to the sensor;
- wherein the substantially planar first surface comprises the end of the substantially transparent body;
- wherein substantially planar first surface has a surface area at least 50 percent the cross sectional surface area of the substantially transparent body, the cross section take in a plane perpendicular to a line intersecting the substantially planar first surface of the transparent body and the sensor.
