Abstract: The control method for lower-limb assistive exoskeletons assists human movement by producing a desired dynamic response on the human leg. Wearing the exoskeleton replaces the leg's natural admittance with the equivalent admittance of the coupled system formed by the leg and the exoskeleton. The control goal is to make the leg obey an admittance model defined by target values of natural frequency, resonant peak magnitude and zero-frequency response. The control achieves these objectives objective via positive feedback of the leg's angular position and angular acceleration. The method achieves simultaneous performance and robust stability through a constrained optimization that maximizes the system's gain margins while ensuring the desired location of its dominant poles.

Abstract: A managed pressure drilling (MPD) operation may use an inverse model in conjunction with a hydraulic model and real-time drilling conditions and parameters as inputs to determine a wellhead pressure set point corresponding to a desired bottomhole pressure. For example, while drilling a wellbore penetrating a subterranean formation with a drilling system, measured data including a wellhead pressure may be acquired. A model may then be executed that applies a hydraulic model to an a priori model estimate vector to produce predicted data; converts the measured data to a measured data vector; applies a randomized maximum likelihood algorithm to the a priori model estimate vector, the predicted data, and the measured data vector to produce an a posterioiri model estimates; and applies the hydraulic model to the a posterioiri model estimates to produce an a posteriori prediction and a calculated wellhead pressure set point corresponding to a desired bottomhole pressure.

Abstract: A loudspeaker system can have first and second loudspeakers selectively operable in a single-channel mode or in a multi-channel mode. In the single-channel mode, the first and the second loudspeakers are configured to simultaneously reproduce a substantially identical signal. In the multi-channel mode, the first loudspeaker reproduces a first-channel signal and the second loudspeaker reproduces a second-channel signal. The first-channel signal and the second-channel signal can constitute respective portions of a multi-channel signal. Such loudspeaker systems can also have a mode selector configured to select one of the single-channel mode and the multi-channel mode. In some embodiments, such selection can occur in response to one or more detected proximities of another loudspeaker system. Multi-zone loudspeaker systems are also disclosed.
