A unique surgical system and method of use includes a seal assembly which is initially mountable about a surgical instrument. Initially, a first transmitter in the wireless network transmits the forward link signal in the first frequency channel. A method includes generating a voltage difference between a match line signal and a reference line signal, and then detecting and amplifying the voltage difference to determine a match or a mismatch. The first resistive region is located proximal to a surface of the structure. Finally, the next cycle estimated error covariance is computed, and the next cycle motion is thereby predicted.
