This paper presents a wireless medical monitoring system. The system permits to receive and process in a single concentrator node (e.g. a laptop or a simple handheld device) the pulse-oximetry signals from one ore several monitored patients without using any wired infrastructure. The system, which is based on a piconet of Bluetooth sensors, can retransmit(More)
Falls are a foremost source of injuries and hospitalization for seniors. The adoption of automatic fall detection mechanisms can noticeably reduce the response time of the medical staff or caregivers when a fall takes place. Smartphones are being increasingly proposed as wearable, cost-effective and not-intrusive systems for fall detection. The exploitation(More)
Much work has been carried out in recent years on the beneficial effect of phenolic compounds as natural antioxidants which help to neutralize free radicals. In fact, researchers have focused their attention on the pathological role of free radicals in a variety of diseases, among which the most important are atherosclerosis and cancer. Thus, among the(More)
Falls are a major cause of health and psychological problems as well as hospitalization costs among older adults. Thus, the investigation on automatic Fall Detection Systems (FDSs) has received special attention from the research community during the last decade. In this area, the widespread popularity, decreasing price, computing capabilities, built-in(More)
This paper evaluates and characterizes the technical performance of medical wireless personal area networks (WPANs) that are based on smartphones. For this purpose,a prototype of a health telemonitoring system is presented. The prototype incorporates a commercial Android smartphone, which acts as a relay point, or "gateway", between a set of wireless(More)
Bluetooth is currently a major technology for the deployment of wireless short range communications. This paper presents an analytical model to compute the delay of Bluetooth transmissions with Serial Port Profile (SPP), which is nowadays widely utilized by commercial Bluetooth-enabled devices. In particular, the proposed equations permit to estimate the(More)
— This paper presents a system whose purpose is to monitor a patient continuously from indoor or outdoor environments. The system is based on a Bluetooth PAN, carried by the patient, whose central node, a smart phone, compiles information about patient's location and health status. These data are encrypted to be sent to a server through Wifi or GPRS/UMTS.(More)
Bluetooth is by far the most employed technology to develop practical applications of Wireless Personal Area Networks (WPAN). This paper studies the performance of Bluetooth transmissions that make use of the Bluetooth PAN (Personal Area Network) profile. In particular, the study offers an analytical model that defines the optimal bound for the end-to-end(More)
This paper presents a prototype developed in Python of a pervasive mobile health system aimed at monitoring a patient in indoor and outdoor environments continuously. The system is based on a Bluetooth PAN (Personal Area Network), worn by the patient, whose master node, a smartphone, collects information about patient's location and health status and(More)
