Liquid crystals take the cold

Article Abstract:

Passive Liquid Crystal indicators, which were discovered in the mid-nineteenth century will now be used in refrigerators and will indicate if a refrigerator is running at low temperature. B&H Liquid Crystal Devices, the innovators of the product say that the indicators will also issue other thermally induced warnings.

Dark spot shows gas dew point

Article Abstract:

The 'Condumax II' is an automatic dew point meter for natural gas that uses the formation of a dark spot, in light reflected by a film of liquid, to detect the onset of condensation. The technology, available from Michell Instruments, eliminates the human factor in measuring dew point in critical applications.

A liquid crystal eye for detail

Article Abstract:

Lenses can be made to change their focus without the use of moving parts, by electrically addressing arrays of liquid crystals. One of the most interesting potential applications of this technology is to correct vision.
