Poor sleep can be attributed to many causes, including shift work, stress, snoring or even sleep apnea – a disorder in which the sleeper temporarily stops breathing. Until now, only a sleep laboratory could determine whether a patient is suffering from sleep apnea or related sleep disturbances.
In a traditional sleep laboratory, the patient is observed while sleeping for at least one night, connected to cables and observed by a large number of measuring instruments and cameras. Researchers at the Fraunhofer Institute for Integrated Circuits IIS in Erlangen have now developed a mobile sleep lab for home use.
SomnoSENS consists of a small box that is worn attached to the body during sleep and observes vital functions. Four adhesive electrode pads are used to record an electrocardiogram (ECG), while a finger clip measures the patient’s blood oxygen level and pulse rate. A nasal clip and expandable belts around the upper torso monitor breathing, and a movement sensor in the device identifies the patient’s body position and registers how much he or she moves. “The device is attached to the body during sleep and does not hinder sleep comfort due to its miniature size,” Herbert Siegert from IIS assures. “SomnoSENS records and stores the data, and transmits them to the base station via a Bluetooth wireless interface. The physician can later evaluate the stored information to make an evidence-based diagnosis.”
Heart patients simply wear a small, lightweight device on their body. It records heartbeats via a 3-channel ECG, identifying minimum and maximum heart rates as well as arterial fibrillation. At the same time, the device records movement. A physician can evaluate, for instance, the heart rate in connection with physical effort, thus simplifying the diagnosis. The system also permits recovery time to be determined after physical exercise. The data are transferred via a home gateway to an Internet portal where the physician can access the information remotely. A range of optional components can be added to the system to measure other vital data such as blood pressure, weight or blood sugar level.ActiSENS – Keeping active
During the day, the current score can be displayed on the device at any time. In the evening, the accumulated data for the day can be transferred to a PC via Bluetooth and analyzed in greater depth according to previously selected parameters. The data can also be forwarded to a physician for evaluation. In this way it can be determined, for example, whether a patient’s prescribed physical therapy is producing the desired results.

3-D-written model to provide better understanding of cancer spread

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.
The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...
An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
