Gas sensors deliver real-time chemical state information during dynamic process cycles.
Active control laws to stabilize jet engine stall by applying bifurcation control to nonlinear models of axial flow compressors. The controllers employ one dimensional actuation in the form of throttle feedback. Eliminates gear backlash in a multiple-DOF manipulator, reducing noise and vibration associated with gear trains and, at the same time, improving accuracy and stability. This high force, low speed, vibratory linear motor employs electromagnetic excitation and control and is suitable for use in robotics and extreme environments. This hand, which can be attached to a robotic arm, has fingers that can grasp a randomly shaped object lying on a flat plane, and provide fine manipulation of the object.
