Specialist in reusable frameworks since 1993, Etsee Soft, Inc. has launched the brandnew DeCAF 1.2 release of its Java enterprise messaging framework after a large number of positive beta tests in the United States, Europe and the Pacific Rim. DeCAF, reffering to Distributed Command Architecture Framework, also constitutes the software basis for LifeConnect, a telemedicine system for remote patient monitoring, gathering information from distant locations in real time for dissemination, analysis and storage in the doctor's office, the hospital or at home. In Japan, LifeConnect has been implemented at Kurosawa Hospital in Nagano to monitor the patients' vital signs data from their homes or from clinics, situated throughout the islands.
The scaleable DeCAF tool allows the software developer to build distributed applications in Java. There are two versions available, the first one being 100 percent Java whereas the second has been designed for the C/C++ expert. The Etsee Soft company has made the framework accessible in the form of ActiveX and Java Beans components, to provide reusability in no matter what environment. Offering a multitude of design patterns for flexible and fault tolerant programming, DeCAF merely consists of five core classes. Learning two of these classes already suffices to start coding.
The DeCAF 1.2 release is able to support the use of different architectures, namely Sockets, the Common Object Request Broker Architecture, known as CORBA, and DCOM for communication. Users can even mix the three of them by sending messages via Sockets while receiving other ones for further processing via CORBA or DCOM. The product's various beta tests have been performed in several industries, including telecommunications, accounting, financial service, government and automotive, for adequate and thorough evaluation and assessment.
Out of concern for a client centred but cost effective patient care, Etsee Soft has also decided to build its LifeConnect remote monitoring solution on the object oriented technology of the DeCAF infrastructure. In Japan, at the Kurosawa Hospital in Nagano, the system has been installed on a Windows NT platform. The medical equipment consists of a tabletop unit, designed by NEC, in order to monitor the patient's pulse, temperature, blood flow, his electrocardiogram data, and other vital functions. Using the touch screen, the health care provider is able to conduct a question and answer session with the patient.
Manual data entry with regard to body weight, urine analysis and blood glucose status is equally possible in the LifeConnect unit for transmission to the central server by means of ISDN lines. The system allows to maintain an updated database with the history of vital signs, progress notes, allergies, medications and even the equipment used for each patient. In emergency as well as in normal call procedures, the health care professional can assist the patient needing help in a safe and secure manner throughout the continuum of care. The use of LifeConnect in Japan has proven that this telemedicine solution lends itself to customized feature design for typical local situations.
