A method, carried out in an arrangement having a cable that provides programming information to a video monitor as well as telephony service, where call progress information of a telephone call is displayed on the monitor, and the method sends control information upstream, over the cable, in connection with desired information relative to the call progress. One or more control outputs are provided to actuators associated with the machine according to the refined control output vector. This thin layer of native oxide is made more robust by applying a second oxide plasma treatment to exposed surfaces, this more robust layer of native oxide protects the polysilicon fuse during subsequent processing steps of wet photoresist and polymer removal. The mounting devices may also include either or both of a windshield brace arm and a dash board brace arm to increase the stability of the mounting device. Electrical contact of the substrates on which the micromirrors and electrodes are formed can be made through many ways, such as electrical contact areas, electrical contact pads and electrical contact springs. One or more Doppler chips can be mounted or incorporated into the system which permit the practitioner to better identify the uterine artery and monitor blood flow therein.
