A real-time computer vision system tracks one or more objects moving in a scene using a target location technique which does not involve searching. The apparatus receives a telephone transaction initiation message that originated with a telephone set located in a first network. In response to the state of the voice input state being a mute state, the processor unit identifies a first setting for the mute state. The processes combine graphic arts techniques with photogrammetric techniques to preserve, fully or partially, information about an object as captured in image detail of said object and to present said information in photogrammetrically correct rendering, which rendering may be incorporated into drawings useful to andor familiar to end users of said drawings. Following successful completion of this test, the top-out plumbing is completed, leaving the test cap welded in place. The circuit uses a unique combination of subfield and power inversion techniques to carry out multiplicative inversion.
