Free of most social constraints, elderly people tend to perform activities of daily living following the same sequence. This paper proposes a method for medical telesurveillance to detect and quantify a nycthemeral shift in this daily routine. While this common phenomenon is mostly mild, in acute cases, however, it may reveal a pathological behavior requiring a rapid medical examination. This method...
We have developed a non-invasive system for monitoring cardiac vibrations, respiration and body movement of in-bed hospitalized patients and elderly people who need constant care. These physiological parameters are recorded by an infrared emitting diode and a photo transistor, which are attached between spring coils in bed mattress. The infrared emitting diode diffuses infrared light into the mattress...
The number of elderly who live on their own is increasing. Falls in the elderly are a major problem which has a long term effect. If the elderly can get help immediately after a fall, the severity of the injury, and the cost could be reduced. This paper presents a fall detection algorithm utilizing two thresholds for the resultant acceleration in 1.5-s window segments. Data was acquired using a tri-axial...
