Title: Microfluidic valve and system therefor
Inventor: CHO STEVE T
IPC: F16K31/02
Filed: 2003-02-03
Abstract: A valve (105) controls fluid flow in a microfluidic system (100). The valve (105) has an input port adapted to receive fluid exerting a predetermined level of pressure on the valve (105) and an output port.

Abstract: L'invention concerne un gyroscope microélectromécanique (MEMS) présentant au moins une masse d'épreuve mécaniquement reliée à un substrat au moyen de ressorts. Une force motrice actionne les masses d'épreuve à leur fréquence de résonance dans un seul sens, à 180 degrés en dehors de la phase les unes par rapport aux autres dans le cadre d'un gyroscope à masse d'épreuve double. Des électrodes de détection détectent le mouvement des masses d'épreuve en réponse à la force de Coriolis. Le mouvement causé par la force de Coriolis est perpendiculaire au mouvement provoqué par la force motrice. Une tension de pompage CA qui fait le double de la fréquence motrice est appliquée sur les électrodes de détection afin de fournir une amplification paramétrique de la force de Coriolis. La tension de pompage CA modifie le gain mécanique et électrique du gyroscope.
