Helmholtz resonance in a piezoelectric–hydraulic pump-based hybrid actuator

This paper demonstrates that a hydraulically acting Helmholtz resonator can exist in a piezoelectric–hydraulic pump (PHP) based hybrid actuator, which in turn affects the volumetric efficiency of the PHP. The simulation and experimental results illustrate the effect of Helmholtz resonance on the flow rate performance of the PHP. The study also shows how to shift the Helmholtz resonant frequency...

Magnetic resonance imaging to detect acute cerebral events in on-pump and hybrid-pump patients.

BACKGROUND Conventional cardiopulmonary bypass results in cerebral ischemic sequelae that may be reduced with hybrid pump technologies, such as the CardioVention system (CardioVention, Santa Clara, CA, USA). CardioVention differs from conventional bypass in that it has a novel air elimination module and reduced membrane surface area and priming volume. This preliminary study tested whether this...

MEMS Helmholtz coils for magnetic resonance imaging

Miniature coils for magnetic resonance imaging and spectroscopy are demonstrated. A rectangular Helmholtz arrangement based on a pair of substrates separated by spherical alignment spacers is investigated. An optimal geometry is developed using simple theory and verified by numerical analysis. Prototypes are fabricated using silicon substrates shaped by anisotropic etching to form a trough to h...
