Optically switchable diffraction gratings would be particularly useful for all-optical switching and multiplexing [5] and could be used, for example, in add/drop [4] modules in optical communication systems that are needed for dense wavelength division multiplexing.
So this could be used, for example, for a delivery service.
It could be used, for example, in measurement of standing waves, calibration of devices, etc.
If enacted, it could be used, for example, to force search engines to stop linking to sites deemed improper.
They are exploring the different ways sensors could be used, for example, to help farmers regulate their use of fertilisers.
Such imaging could be used, for example, to monitor plaques as they build up in blood vessels.
The reconstruction of extinct genes could be used, for example, to restore genetic diversity in threatened species or subspecies.
It wouldn't have to be worn all the time, but could be used, for example, when driving.
The process could be used, for example, for moving, positioning, and patterning segments of DNA strands for the fabrication of ultra-dense gene chips.
Chemical sensors could be used, for example, to detect toxic substances in hazardous areas so that people can go into the area with the appropriate safety gear.
Such technologies could be used, for example, to harness solar energy, sense early signs of Alzheimer's disease in people's brains and create various types of OLED display.
