Researchers at the University of Missouri and TigerPlace, an independent living community, have been using motion-sensing technology to monitor changes in residents' health for several years. Now, researchers have found that two devices commonly used for video gaming and security systems are effective in detecting the early onset of illness and fall risk in seniors.
Marjorie Skubic, professor of electrical and computer engineering in the MU College of Engineering, is working with doctoral student, Erik Stone, to use the Microsoft Kinect, a new motion-sensing camera generally used as a video gaming device, to monitor behavior and routine changes in patients at TigerPlace. These changes can indicate increased risk for falls or early symptoms of illnesses.
"The Kinect uses infrared light to create a depth image that produces data in the form of a silhouette, instead of a video or photograph," said Stone. "This alleviates many seniors' concerns about privacy when traditional web camera-based monitoring systems are used."
Another doctoral student, Liang Liu, is collaborating with Mihail Popescu, assistant professor in the College of Engineering and the Department of Health Management and Informatics in the MU School of Medicine, to develop a fall detection system that uses Doppler radar to recognize changes in walking, bending and other movements that may indicate a heightened risk for falls. Different human body parts create unique images, or "signatures," on Doppler radar. Since falls combine a series of body part motions, the radar system can recognize a fall based on its distinct "signature."
"Falls are especially dangerous for older adults and if they don't get help immediately, the chances of serious injury or death are increased," said Liu. "If emergency personnel are informed about a fall right away, it can significantly improve the outcome for the injured patient."
Both motion-sensing systems provide automated data that alert care providers when patients need assistance or a medical intervention. The systems currently are used for monitoring residents at TigerPlace in Columbia. Skubic says the system allows residents to maintain their independence and take comfort in knowing that illnesses or falls may be detected early.
Stone's study, "Evaluation of an Inexpensive Depth Camera for Passive In-Home Fall Risk Assessment," won the best paper award at the Pervasive Health Conference, in Dublin, Ireland in May. Liu's study, "Automatic Fall Detection Based on Doppler Radar Motion," received the best poster award at the conference. Liu's paper was a collaboration with GE Global Research and co-authored by Tarik Yardibi and Paul Cuddihy. TigerPlace is a joint project of the Sinclair School of Nursing and AmErikare, a long-term care company.

The research is part of Mizzou Advantage, the five unique areas that set MU apart from other universities. The project contributes to the "Managing Innovation: Navigating Disruptive and Transformational Technologies" initiative that will touch on virtually every part of the university to explore areas in which existing technologies are changing rapidly.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
