    • A method (700, 800, 900) and apparatus (1000, 1100) increase a signal quality by analyzing an input signal and output signals from adaptive filters (410, 510, 512, 514) associated with predetermined signal plus noise plus interference classifications. An actual signal plus noise plus interference classification of the input signal is determined and one of the output signals or the input signal is selected based on a favorable Signal to Noise Ratio or a Signal to Interference plus Noise Ratio. The output signals from the adaptive filters are weighted based on analysis such as statistical analysis (310) including quantified auto-regressive analysis, Eigenvalue spread analysis, correlation analysis, feedback analysis, and covariance analysis. The predetermined classifications include various combinations of characteristics associated with the signal and interference components.

    • A deflection limiting member (110, 310) or a deflection limiting mechanism (512, 514) is used to limit deflection of a motor shaft (102) of a vibrator (105, 305, 505) in a portable electronic device (104,304, 504). The deflection limiting member (110, 310) extends in a radial direction from the motor shaft (102) on a side of the motor shaft (102) that is opposite to the center of gravity (108, 308) of an eccentric weight (108, 308). The deflection limiting member (110, 310) contacts a fixed surface such as a printed circuit board (112) to limit deflection of the motor shaft (102). The deflection limiting mechanism (512, 514) prevents an inertial force of an eccentric weight 510 from being applied directly to the motor shaft (102) under conditions in which there is a high risk of permanent deformation of the motor shaft (102).
