Using the daylight savings clock change to show ambient light conditions significantly influence active travel

Accidental death and the shift to daylight savings time.

Daylight savings time and myocardial infarction

BACKGROUND Prior research has shown a transient increase in the incidence of acute myocardial infarction (AMI) after daylight savings time (DST) in the spring as well as a decrease in AMI after returning to standard time in the fall. These findings have not been verified in a broader population and if extant, may have significant public health and policy implications. METHODS We assessed chan...

Using the life satisfaction approach to value daylight savings time transitions. Evidence from Britain and Germany

Daylight savings time (DST) represents a public good with costs and benefits. We provide the first comprehensive examination of the welfare effects of the spring and autumn transitions for the UK and Germany. Using individual-level data and a regression discontinuity design, we estimate the effect of the transitions on life satisfaction. Our results show that individuals in both the UK and Germ...

Using Networked Sensors to Detect Ambient Light

An understanding of the capabilities of the Mica mote light sensors is currently limited. To determine how much information data from the light sensors reveals about the environment, we performed a series of experiments designed to test the sensitivity of the light sensors to the time of day, the presence/absence of close objects, and different colors. Measuring the ambient light alone, we disc...

Influence of ambient light on cerebral oximeters.

Editor—Cerebral oximetry has become a standard monitoring in cardiac surgery and some studies have shown its usefulness in non-cardiac surgery. 2 In the future, it may become widely used for routine monitoring. There are two different technologies used, absolute and relative oximetry. Absolute oximetry uses fibreoptic laser light of four different wavelengths (690, 780, 805, and 850 nm; ForeSig...
