Abstract: A wearable platform embodied in a belt or patch provides physiological monitoring of soldiers during field operations or trauma victims at accident sites and makes health state assessments. The platform includes sensors for heart rate, body motion, respiration rate and intensity, and temperature and further contains a microprocessor and short range transmitter. An analog circuit running an algorithm obtains the R-wave period from the EKG signal and produces electrical pulses with the period between pulses corresponding to the R-wave period. A rule based processing engine having an evaluation algorithm is capable of making a medical evaluation of subject condition and determines a confidence level for the evaluation. The rules are subject to variation depending upon the subject population. The information is communicated wirelessly to a local hub for relay to a remote monitor.

Abstract: An application is built in accordance with a particular application framework. A component is incorporated into the application. When an asynchronous operation is to be performed, the component is configured to issue a standard function call in a manner that is independent of the particular application framework used to build the application. An asynchronous operations manager is configured to detect the particular application framework used to build the application, receive the standard function call, perform the asynchronous operation in accordance with a threading and concurrency model of the application framework, and cause a notification to be issued to the component in a manner that is in accordance with the threading and concurrency model when the asynchronous operation is complete. The asynchronous operations manager may determine the application framework by receiving a notification or function call from the application framework itself.

Abstract: A component-based framework includes system services and component integration interfaces that provide a run-time environment for component-based server application in which server application components have control over the duration of their state independent of client action. The framework provides functions that a server application component calls to indicate its work for a client is complete, and its state is to be destroyed. On the component's return from the client's method call, the framework destroys the component's state thus releasing any server computer resources held by the component. This allows the server application components to be programmed so as to minimize the duration that their state remains in memory consuming server computer resources, and which enhances scalability of the server application.
