Supervising Event Executive

There are many advances in nurse-call devices but there is a lack of proper integration and interoperation among them. This paper presents a software application to join these devices together in a LAN environment such as Hospital Information System. This software application is called Supervising Event Executive (SEE) that is developed to provide a common, convenient, and reliable means of transferring system events (and commands). The SEE primarily supports four types of applications. First type is called event publisher that generates LAN events from devices. Second type is called event subscriber that consumes LAN events from devices. A subscriber application typically takes some action based on an event. Third type is called resource provider that provides resources or services to consumer applications. The resource provider is typically managed through commands in a request / response nature. In addition, the resource provider may also publish events regarding the status of managed resources. The final type is called resource consumer that consumes resources or services managed by `Resource Provider´ applications.
