RESUMO
The great diversity in the architecture of hardware devices allied to many communication protocols, has been hindering the implementation of systems that need to access these devices. Given these differences, it appears the need of providing the access of these devices in a transparent way. In this sense, the present work proposes a middleware, mult input and output for access the devices, as a way of abstracting the writing and reading data mechanisms in hardware devices, contributing this way, for increasing systems productivity, as the developers are just focused in their functional requirements.

RFID is a technology being adopted in many business fields, especially in the medical field. This work has the objective to present a system for automation of a hospital clinical analysis laboratory. This system initially uses contactless smart cards to store patient's data and for authentication of hospital employees in the system. The proposed system also uses RFID tags stuck to containers containing patient's collected samples for the correct identification of the patient who gave away the samples. This work depicts a hospital laboratory workflow, presents the system modeling and deals with security matters related to information stored in the smart cards.

This paper presents a Multicycles Protocol for Hospital Automation (MP-HA) that works over multicast addressing and uses a Master-Slave architecture. The protocol creates a segmented logical network based on multicast addressing associated to hospital beds. The objective of MP-HA is to ensure the determinism on network through medium access control mechanism increasing the transmission throughput. Thus, it creates a periodical environment making use of parallel cycles which is called multicycles.
