Across the world, healthcare costs are projected to continue to increase, and the pressure
on the healthcare system is only going to grow in intensity as the rate of growth of elderly …

We explore the application of a wide range of sensory stimulation technologies to the area of
sleep and dream engineering. We begin by emphasizing the causal role of the body in …

Advances in mobile networks and low-power electronics have driven smart mobile medical
devices at a tremendous pace, evoking increased interest in household healthcare …

We present an example of unobtrusive, continuous monitoring in the home for the purpose
of assessing early health changes. Sensors embedded in the environment capture behavior …

Benefiting from non-invasive sensing tech-nologies, heartbeat detection from
ballistocardiogram (BCG) signals is of great significance for home-care applications, such as …

Using geophones to sense bed vibrations caused by ballistic force has shown great
potential in monitoring a person's heart rate during sleep. It does not require a special …

Environmentally embedded (nonwearable) sensor technology is in continuous use in elder
housing to monitor a new set of 'vital signs' that continuously measure the functional status of …

Sleep posture has been shown to be important in monitoring health conditions such as
congestive heart failure (CHF), sleep apnea, pressure ulcers, and even blood pressure …

Ballistocardiogram signals produced by hydraulic transducers placed under the bed
mattress are used to estimate heart rate using two proposed methods. The first method uses …

A multiple instance dictionary learning approach, dictionary learning using functions of
multiple instances (DL-FUMI), is used to perform beat-to-beat heart rate estimation and to …
