It contains a device that measures such things as temperature, motion and light intensity, and it sports a miniature antenna and a radio with a range of 10 to 50 meters.
The high-intensity light can dazzle pilots during take-off and landing when shone at aircraft.
Similarly located structures less than 45 metres tall may require a low-intensity light.

According to the Civil Aviation Authority (CAA), the high intensity light can dazzle pilots during the crucial phases of take-off and landing.

One example the company has developed is a crystal fibre that squeezes light into such a narrow core that the intensity of the light modifies the optical properties of the glass itself.
GentleWaves inventor McDaniel says he can send specific instructions to cells by changing the light's wavelengths, frequency or intensity, but he says the light "codes" he has created are proprietary.
Each pixel's charge varies according to the intensity of the light striking it.
And under International Civil Aviation Organisation regulations, any structure over 45 metres tall on a flight path or near an aerodrome must be fitted with a medium-intensity aircraft warning light.

What Rand and his colleagues found is that at the right intensity, when light is traveling through a material that does not conduct electricity, the light field can generate magnetic effects that are 100 million times stronger than previously expected.
In this regard, we need to examine existing cohorts of children who years ago were truly infected (or were assumed to be infected) and were treated not within hours of detection of virus but within weeks to months to determine if such cases had similar outcomes to the Mississippi child and can shed light on the timing and intensity of starting therapy.
McDaniel says that he can send instructions to cells by changing the light's wavelengths, frequency or intensity.
The other is a non-contact method by detecting intensity of the invisible infrared light that naturally emanates from every surface in this Universe.
Professor Stephen Rand and his associate, William Fisher, have discovered that, at the proper intensity, the magnetic properties of light could potentially be harnessed to generate voltage.
He acknowledges using yellow and red light, but he refuses to say what power intensity is used or for how long.
Tubes at the top and bottom are intended to catch these flashes of light and tell scientists both the location and the intensity of the interactions.
If the light is polarised, there is only one way to orient the crystal to produce beams of equal intensity.
