In yet another embodiment, piezo and MEMS tuning can both be used to provide a combination of a slower, large stroke tuning mechanism, and a faster, small stroke tuning mechanism. These tuning mechanisms can be combined further with other tuning mechanisms such as carrier injection tuning in ...
A dual-stage brake servo booster was adopted, which provides clear feedback when the brakes begin to work as well as moderate feedback force, realizing excellent brake feel and enhanced controllability. A new actuator, V3-ACV, was added to decrease stroke when the brake pedal is applied. RX ...
A linear electromechanical actuator (10) comprises a casing (30) with a longitudinal axis (x) and an electric motor (11) for rotating a disc (20) about an axis (x) between two angular positions. A piston (50) is guided axially slidable relative to the casing (30) . Interposed between...

This paper outlines a study of a short-stroke rectilinear version of the Laws' relay actuator, for use in reciprocating electromechanical systems. Finite element analysis provides the static characteristics of the device, and the analysis is coupled to a nonlinear state-variable time domain simulation...
