Zusammenfassung:	A method and apparatus is provided to detect the position of an object, such as a container, in a target window using the concept of triangulation of light radiation. A transmitter emits a pulse of light in response to a periodic clock pulse which is at least partially reflected off the container positioned in the target window and into a receiver, forming an optical triangle. The target window has the volumetric shape of two intersecting cones and therefore provides three axes detection. The signal produced by the receiver in response to receiving a light input is filtered to remove weak signals and checked to ensure that the light indicative signal is synchronous with the periodic clock pulse to eliminate errant light sources. The presence of a synchronous signal indicates the presence of an object in the target window wherein subsequent action may be taken, such as dispensing beverage and/or ice into a container within the target window.
