Compliant Wren mechanisms (CWM) constitute specific compliant structures of particular interest. Derived from mechanisms, they can exhibit a large variety motions, quasi translation to rotation. In this paper, the development models for analysis and synthesis CWM is considered. A kinematic model introduced first assess all possible motions when used as an actuator. Then static stress expression...

We present and discuss detailed measurements of TCP in the European ATM Pilot. In this wide area ATM network, the traffic contract is enforced by a Usage Parameter Control (UPC) mechanism. We show that when the ATM level traffic was compliant, TCP achieved a good utilisation of the link. However, when the ATM level traffic was only almost compliant, the TCP throughput almost collapsed.

In order to investigate the influence of the stiffness of the compliant prismatic pair, a planar four-bar parallelogram, in a fully compliant parallel mechanism, the stiffness model of the passive compliant prismatic pair in a compliant parallel positioning stage is established using the compliant matrix method and matrix transformation. The influences of the constraints and the compliance of t...

Bistable mechanical devices remain stable in two distinct positions without power input. They find application in valves, switches, closures, and clasps. Mechanically bistable behavior results from the storage and release of energy, typically in springs, with stable positions occurring at local minima of stored energy. Compliant mechanisms offer an elegant way to achieve this behavior by incorp...
