The architecture includes a proxy service, an interaction recorder, an interaction store and an emulator service. The first orifice plate includes a first orifice of a first diameter and the first orifice is positioned near an edge of the first orifice plate. The changes in form of the detected light are related to the ability of rhodopsin to absorb light and regenerate, which in turn is related to the concentration of blood glucose, allowing a determination of the relative concentration of blood glucose. The seal groove is formed into the frustro-conical surface along an axis perpendicular to the frustro-conical surface. In one embodiment, the system includes: a stimulus detector, associated with the analog telecommunications equipment, that detects a presence of the in-band stimulus and a stimulus suppressor, coupled to the stimulus detector, that alters the in-band stimulus to cause the analog telecommunications equipment to disregard the in-band stimulus.
