Laparoscopic surgery and the market for its robotic devices keep growing since postoperative complications are fewer and patients recover quicker than conventional laparotomy wounds, even though robotic surgery is 5-6 times more expensive than traditional laparotomy. We are developing surgical robot system with minimally invasive robotic surgical tools. And to use those tools in surgery, the mechanism of system needs to be simple and durable to reduce the cost of robotic surgery. In this paper, we present some mechanisms for minimally invasive surgical robot tools that have simple structure, easy to manufacture and control.
the success of any diagnosis strategy critically depends on the sensors measuring process variables. this paper presents a strategy based on diagnosability maximization for optimally locating sensors in distribution n...

Ensuring adequate security and privacy of health information is a moral and legal mandate of the twenty-first-century healthcare industry that is fast moving towards complete digitalization. As a consequence of increased threats to security of electronic health records, a genuine need for a robust and effective authentication and access control schemes has emerged. Since healthcare systems pose some unique security constraints, especially in case of access control, none of the extant off-the-shelf solutions is directly applicable. In this paper - recognizing the fact that authentication is an indispensable precursor to access control - we address both issues together by proposing a robust authentication scheme and a hybrid access control model for healthcare informatics. We explain the design and implementation of the proposed system, and discuss evaluation results that were found to successfully satisfy various security requirements of the healthcare domain.

the last decade has seen the emergence of a unified approach for product design which attempts to combine traditionally distinct tasks such as design, management, marketing, analysis, manufacture and materials. Often called "Concurrent Engineering" or "Simultaneous Engineering," this new philosophy aims at improving cost competitiveness by reducing waste of time, money, and other resources inherent in the iterative traditional methods. In view of the importance of this new philosophy, Concurrent Engineering is selected as the theme for this conference. the main objective of the conference was to bring together researchers and practitioners from government, industries and academia interested in the multi-disciplinary and inter-organizational productivity aspects of advanced manufacturing systems utilizing CAD/CAM, CAE, CIM, Parametric Technology, AI, robotics, AGV Technology, etc. A selection of the papers presented at the conference are organized into two volumes emphasizing the aspects of Concurrent Engineering and Flexible automation.

the concept of control of plants represented by (1) has been proposed. Using (2),(3),(4),(5) one can determine plant input U(t) forming its output as Y(T), where "new" time T depending on time-scale A(t) is defined by dT=A(t) dt, whereas Y(t) is plant "reference" output obtained for A=1. Signal A(t) is obtained as result of static operation A(t)=q(e(t)), where q(0)=0 and e(t) is control system error. the technical applications can base on MFC structure (Fig. 4). the idea of control is simple: if e(t)=A(t)=0, then model (2) is decoupled, values of its state variables and output y are conserved. Because Y follows y (Fig. 4), then changes of plant output are stopped too. If e(t)=A(t) not equal 0, then y and Y tend to reference signal y(o) and rate of follow-up action depends on q(e(t)). During this process the consecutive outputs of model and plant are y(T) and Y(T). thus, the "reference" response Y(t) defines Y(T). the impressive results illustrating properties of proposed concept are shown in Fig. 5,6. Application of described method simplifies the analysis of system dynamics and yields perfect results of follow-up action (lack of overshoots, short setting times). the idea for SISO case has been generalized to form enabling control of MIMO plants.
