A study of parametric excitation applied to a MEMS tuning fork gyroscope
(University of Missouri--Columbia, 2007)
The current MEMS ( gyroscopes which normally use the electro static force to excite the comb drive are faced with the limitations such as low precision, coupling problem, and poor robustness. We propose to use parametric ...
Kinematic analysis of cam profiles used in compound bows
(University of Missouri--Columbia, 2009)
The first compound bow was invented in Missouri in 1969. [Allen, 1968] Compound bows are uniquely different from other types of bows in that they use a set of cables, cams and pulley, and two elastic limbs that act as ...
