文摘For healthcare organizations, there is increasing needs to share data among applications to deliver qualitypatient care. It is a key for successful diagnosis and treatment to view accurate and up-to-date patient data in a single information dashboard in real time. But the fact is that many hospitals and healthcare providers today are struggling with legacy system or internally developed systems that cannot easily scale to support new interfaces; the plethora of inflexible point-to-point interfaces make changing in one system deleteriously impact other systems; some systems could not support information sharing; and the standards followed by different systems are not compatible to each other. This is making it increasingly difficult to meet the rapidly changing and demanding of healthcare service.
文摘Computer intergrated manufacturing system (CIMS) applications in manufacturing enterprises need new advanced support tools for application integration. This paper presents the system architecture and functions for CIMS application integration platform for manufacturing enterprises (MACIP). MACIP integrates a set of application software products and development tools as a complete system for CIMS implementation. MACIP includes a communication system, a global information system, three domain application sub integration platforms, an internet interface and an operation management and control system. The Client/Server structure, the object oriented method and the agent technique were used in developing MACIP. Good system openness, scalability, and maintenance are ensured by conforming to international standards and by using advanced system design software and management tools. MACIP can significantly reduce the implementation complexity, time, and cost of CIMS.
文摘Common object request broker architecture (CORBA) provides the framework and the mechanism for distributed object operation. It can also be applied to computer integrated manufacturing system (CIMS) application integration. This paper studies the CIMS information service requirement, presents a CORBA based integration approach including the CORBA based CIM information system architecture and the application integration mechanism, and discusses the relationship between CORBA and the CIM application integration platform.

文摘To efficiently search out the optimal cam contour,a software integrated optimization method considering cam mechanism’s kinematic and dynamic characteristics was presented,and its effectiveness was demonstrated by a case study of the cam contour optimization for an offset press open-close gripper mechanism.The acceleration curve and the residual vibration model of the follower were separately studied.A symmetric harmonic trapezoidal curve was designed to control the follower’s acceleration,and single-DOF lumped parameter torsional vibration model was proposed to describe the follower’s residual vibration.Accordingly,corresponding motion curve design software and Simulink vibration model of the follower were developed respectively,and they were integrated into an automatic optimization platform with iSIGHT.The multi-objective optimization with objectives of minimizing both the acceleration and the residual vibration of the follower was completed within the platform by using NSGA-II algorithm.An appropriate point with lower acceleration and residual vibration was chosen from Pareto front as an optimal solution of the follower’s motion curve.Based on the follower’s new motion curve,the actual cam contour was generated by inverse kinematic simulation in COSMOSMotion.The offset press that installed our new designed cam exhibited a lower vibration than the previous machine,and the maximum measured acceleration of the offset press at a printing speed of 15000 r/h is reduced by 7.7%.

文摘This study presents a wafer-level sealed silicon cavity(SSC)microacoustic integration platform to address the limitations in the cavity Silicon-on-Insulator(C-SOI)wafers for the 5G/6G wireless communication system.The proposed SSC platform features an extremely smooth suspended membrane with adjustable thickness,flexible cavity shapes with high density,self-formed acoustic wave confinement steps,stable temperature coefficient of frequency(TCF),and highly integrated compatibility with complementary metal-oxide semiconductor(CMOS).A surface smoothing method based on wet oxidation for SSC wafers is presented,which achieves a root mean square(RMS)roughness on the cavity surface of 1.5 nm for the first time.Based on the presented SSC platform,an Al_(0.75)Sc_(0.25)N sealed cavity bulk acoustic wave resonator(S-BAR)is designed,fabricated,and characterized.The experimental results show that the asymmetric second-order(A2)Lamb mode of S-BAR is enhanced for higher frequency with a maximum piezoelectric coupling coefficient(k_(t)^(2))of 9.53%,a maximum quality factor(Q)of 439,and a TCF of−11.44 ppm/K.Different designs’piezoelectric coupling coefficient distribution is consistent with the theoretical prediction.The proposed smoothing process increases the S-BARs’quality factor by~400%.The frequency shift caused by the temperature(absolute value of TCF)is reduced by 62%compared with the traditional Al_(0.75)Sc_(0.25)N thin film bulk acoustic wave resonator(without temperature compensation).The enhanced performances demonstrated the potential of SSC in the next-generation highly integrated RF communication systems.
