Compliant mechanisms have been designed for various types of applications to transmit desired forces and motions. In this paper, we explore an application of compliant mechanisms for active vibration isolation systems. For this type of application, an actuator and a compliant mechanism are used to cancel undesired disturbance, resulting in attenuated output amplitude. An actuator provides exter...
This paper introduces the benefits of exploiting elasticity in the engineering design of surgical tools, in general, and of minimally invasive procedures, in particular. Compliant mechanisms are jointless mechanisms that rely on elastic deformation to transmit forces and motion. The lack of traditional joints in these single-piece flexible structures offers many benefits, including the absence ...
In this paper, we describe a study on compliant-parallel (C-P) mechanism with high precision and wide range of working area using bio-inspired compliant joints. C-P mechanism is a parallel mechanism in which all of joints are composed by wide deformable compliant joints. In the integration of the compliant joint and the parallel mechanism, a deformation of the compliant joint can be guided by m...
This correspondence describes a European Union supported collaborative project called CustomTV based on the premise that future TV sets will provide all sorts of multimedia information and interactivity, as well as manage all such services according to each user’s or group of user’s preferences/profiles. We have demonstrated the potential of recent standards (MPEG-4 and MPEG-7) to implement suc...
RDF datasets and SPARQL endpoints hosting them are increasingly available in the life science domain. One consequence is that users have increasing difficulties in finding those endpoints which are reliable and stable. For providers, it is not an easy task to provide appropriate metadata to be easily findable. To solve these issues, we propose a service to provide a place where data providers a...
A unified approach to topology and dimensional synthesis of compliant mechanisms is presented in this paper as a discrete optimization problem employing both discrete (topology) and continuous (size) variables. The synthesis scheme features a design parameterization method that treats load paths as discrete design variables to represent various topologies, thereby ensuring structural connectivi...
The micro/nano motion stage with ultra-high precision are urgently required to perform such tasks as operation under scanning probe, bio-cell manipulation, optical fibers alighment, etc. The compliant XY micro manipulator employing flexure hinges is widely applying due to their excellent characteristics of simple structure, no backlash, no nonlinear friction, and so on [1]. Some novel compliant...
The present work focuses on evolving the multiple light-in-weight topologies of compliant mechanism tracing user defined path. Therefore in this paper, the bi-objective set is formulated first on the optimization frame-work in which the helper objective of maximum diversity is introduced with the primary objective of minimum weight of elastic structures. Thereafter, the evolutionary algorithm (...
A compact, lightweight precision alignment system and package for an endomicroscope was designed and fabricated. The endomicroscope will consist of a millimeter-scale fiber resonator and a two-axis silicon optical bench. The alignment system provided five degrees of freedom and was designed to align the fiber resonator with the microchip with a resolution of one micron. The alignment system con...
