Integrated power electronics module based on chip scale packaged power devices

High performance can be obtained for the integrated power electronics module（IPEM） by using a three-dimensional packaging structure instead of a planar structure. A three- dimensional packaged half bridge-IPEM （HB-IPEM）, consisting of two chip scale packaged MOSFETs and the corresponding gate driver and protection circuits, is fabricated at the laboratory. The reliability of the IPEM is controlled from the shape design of solder joints and the control of assembly process parameters. The parasitic parameters are extracted using Agilent 4395A impedance analyzer for building the parasitic parameter model of the HB- IPEM. A 12 V/3 A output synchronous rectifier Buck converter using the HB-IPEM is built to test the electrical performance of the HB-IPEM. Low voltage spikes on two MOSFETs illustrate that the three-dimensional package of the HB-IPEM can decrease parasitic inductance. Temperature distribution simulation results of the HB-IPEM using FLOTHERM are given. Heat dissipation of the solder joints makes the peak junction temperature of the chip drop obviously. The package realizes three-dimensional heat dissipation and has better thermal management.

Use of content management systems to address nursing workflow

Nurses are at the forefront of providing healthcare services to individuals of all age groups and with varying medical conditions.Aside from the critical knowledge and technical skills from nursing science,advancement in technology has assisted nurses in delivering quality nursing care by streamlining workflow processes and ensuring that data can easily be retrieved or modified.Electronic health records dramatically changed the landscape of the healthcare practice by providing an electronic means to store data and for healthcare professionals to retrieve and manipulate health information in a secured and collaborative environment.But with the nature of data being stored in the electronic health records,nurses still need to organize and process these data into relevant information,knowledge or wisdom so they can provide better holistic care to patients.This discussion paper details the role of content management systems in addressing nursing workflow by providing a mechanism for nurses to be developers themselves,and not just users or consumers of health innovative technologies.By using content management systems as platform for application development,nurses or other healthcare professionals,may be able to address problems with internal workflow without having to incur huge amounts in software development,or having to extensively learn programming languages.

Optimising workflow in andrology: a new electronic patient record and database

Aim： To improve workflow and usability by introduction of a new electronic patient record （EPR） and database. Methods： Establishment of an EPR based on open source technology （MySQL database and PI-IP scripting language） in a tertiary care andrology center at a university clinic. Workflow analysis, a benchmark comparing the two systems and a survey for usability and ergonomics were carried out. Results： Workflow optimizations （electronic ordering of laboratory analysis, elimination of transcription steps and automated referral letters） and the decrease in time required for data entry per patient to 71% ± 27%, P 〈 0.05, lead to a workload reduction. The benchmark showed a significant performance increase （highest with starting the respective system： 1.3 ± 0.2 s vs. 11.1 ± 0.2 s, mean ± SD）. In the survey, users rated the new system at least two ranks higher over its predecessor （P 〈 0.01） in all sub-areas. Conclusion： With further improvements, today＇s EPR can evolve to substitute paper records, saving time （and possibly costs）, supporting user satisfaction and expanding the basis for scientific evaluation when more data is electronically available. Newly introduced systems should be versatile, adaptable for users, and workflow-oriented to yield the highest benefit. If ready-made software is purchased, customization should be implemented during rollout. （Asian J Andro12006 Mar; 8： 235-241）
