<P>PROBLEM TO BE SOLVED: To provide a motor-driven mechanical system with a detection system for measuring properties of a back channel and deriving the oscillatory characteristics of the mechanical system. <P>SOLUTION: Uses of the detection system may include calculating a resonant frequency of the mechanical system and a threshold drive D<SB>TH</SB>required to move the mechanical system from the starting mechanical stop position. System manufacturers often do not know the resonant frequency and D<SB>TH</SB>of their mechanical systems precisely. Therefore, calculating the specific mechanical system's resonant frequency and D<SB>TH</SB>without depending on manufacturer's expected values improves precision in the mechanical system use. Back channel calculations may be used to replace and improve the corresponding pre-programmed values. <P>COPYRIGHT: (C)2010,JPO&INPIT |
