Parents are more likely to get a good night’s sleep if they take their babies out in the early afternoon, according to a study in December’s Journal of Sleep Research.
Yvonne Harrison, from the School of Psychology at Liverpool John Moores University, found that babies who sleep well at night are exposed to twice as much light between 12 noon and 4pm than poor sleepers. 56 healthy, full-term babies were monitored for three consecutive days at six, nine and twelve weeks’ old. Parents were supplied with an environmental light monitor attached to a small teddy bear with Velcro fastenings, so that it could be attached to a pram handle or cot or placed near the baby.
They also used a tried and tested baby diary, which recorded activity such as sleep and crying. “The environmental light monitor measured the normal levels of light that babies were exposed to in an average day” says Dr Harrison. “Parents were asked to continue their usual routines on the days monitored and the light readings were then analysed together with the diaries. “One possible explanation for the link between light exposure and sleep is that higher light levels encourage the early development of the biological clock, which regulates a number of bodily functions, including the secretion of melatonin, an important factor in well-balanced sleeping patterns.”

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
