A tracking beam then captures the movement of the tissue, providing a measure of its elasticity or stiffness.
Water-resistant and dust proof, the GTS-810 Robotic Total Station is also compatible with all existing GTS-800 accessories, including the RC-2 Remote and Optical Communications System which features wireless, one-touch operation for instantly locking on to the tracking beam of the GTS-810.
Error signals to the servo continue to position the platform until the platform is within the narrow tracking beam's 2.5 [degrees] field-of-view.
The RC-2 FastTrak System features wireless, one-touch operation for instantly locking on to the tracking beam of Topcon's GTS-800AR robotic total stations.
[bar over]r = [r.sub.i] when K[is less than] 1 [bar over]r = [r.sub.2] when K[is greater than] 1 (5) The above conclusion is known as the "Dominant Source" theory and is valid whenever two nonfluctuation RF sources are unresolved by an angle tracking beam. It shows that when a large number of radar echoes of constant RF amplitudes and uniform phase distribution are received by a monopulse seeker, its immediate response is toward the dominant source.
