An apparatus for the stabilization of a drinking vessel such as a glass, coffee mug, or a piece of stemware that is placed on a flat or irregular or sloping surface includes a base portion having a flexible outer covering that surrounds a flexible weighted mass. The real part of output impedance Z saw of the SAW filter is closely matched with the real part of input impedance Zic of an RF-IC. The coils are supplied with current pulses that are shorter than the sine oscillations. Spectral and compensation filters are used to improve the characteristics of the beam. Further, a method of applying a radiopaque substance to the instrument organizer.
