Magnetically Actuated Microvalves for Active Flow Control [PDF]
Journal of Physics: Conference Series, 2006 The reattachment of separated air flows can be actively controlled by blowing oscillatory air jets in the boundary layer, through submillimetric holes situated near the separation edge. To achieve such pulsed jets, a high flow rate, high actuation frequency microvalve was designed, fabricated and characterized.

Active gaze control improves optic flow-based segmentation and steering. [PDF]
PLoS ONE, 2012 An observer traversing an environment actively relocates gaze to fixate objects. Evidence suggests that gaze is frequently directed toward the center of an object considered as target but more likely toward the edges of an object that appears as an ...
