The measurement of light can be separated into a range of measurement principles. Each of these measurement principles is quantified according to different optical parameters. In the case of ...

Using LEDs for backlighting presents the designer with various options and challenges. One must balance a number of considerations, such as display brightness, power consumption, part count, battery ...

Objectives To determine whether quantifying both the absolute and relative intensity of accelerometer-assessed physical activity (PA) can inform PA interventions. We hypothesised that individuals ...

White LEDs (WLED) are increasingly becoming the light source of choice for backlighting applications due to their attractiveness in power efficiency and form factor. Display solutions in portable ...
