Development of an Application for Aid in Cataract Screening.

Cataract is the main cause of reversible vision impairment in developed countries, and at the age of 70, almost all of them will have developed some degree of it. `Cataract' is the name given to any congenital or acquired opacity in the natural lens capsule or substance of the eye. In this context, this paper presents TriOft, an embedded teleophthalmology system, which uses the smartphone, for cataract screening. This application makes possible using the cell phone as a tool, considering its easiness for handling and transporting, as well as the benefits for the more remote regions, where there is no an easy access to a doctor, specialized or not.

S2DIA: a diagnostic system for Diabetes mellitus using SANA platform.

Currently, Diabetes is a very common disease around the world, and with an increase in sedentary lifestyles, obesity and an aging population the number of people with Diabetes worldwide will increase by more than 50%. In this context, the MIT (Massachusetts Institute of Technology) developed the SANA platform, which brings the benefits of information technology to the field of healthcare. It offers healthcare delivery in remote areas, improves patient access to medical specialists for faster, higher quality, and more cost effective diagnosis and intervention. For these reasons, we developed a system for diagnosis of Diabetes using the SANA platform, called S2DIA. It is the first step towards knowing the risks for type 2 Diabetes, and it will be evaluated, especially, in remote/poor areas of Brazil.

Design of an embedded PID controller applied to blood pressure control.

Some diseases, such as hypertension, require a close control of the patient's blood pressure. This is even more critical when that patient is going through--or has just underwent--a surgical procedure In such situations, reducing blood pressure to normal levels is of paramount importance. Usually, this demanding and time consuming monitoring is done manually by clinical personnel and are subject to mistakes and inconsistent practices. In this paper, we propose a solution to the manual monitoring through the design and implementation of an embedded PID controller to handle blood pressure, integrated to an automated monitoring system to assist in detecting anomalies and to optimize the process of patient care.
