These devices work at low voltages, comparable to their bandgaps, and they are used in industrial process control, pollution monitoring, light detection within fibre optics telecommunications networks, solar cells, imaging, and many other applications.
This paper compare two types of monitoring: light-weight monitoring (LWM) and heavy-weight monitoring (HWM).
This can involve two-handed engaging, protective door monitoring, light curtains, safety mats, and emergency stop relays.
Last year, Google released a fun app that let curious kids perform a handful of science experiments by monitoring light, sound and motion using a smartphone.
Still, he says that people trying to lose weight in the future might think about monitoring light exposure in addition to food.
The present study demonstrates the use of front-face fluorescence spectroscopy and chemometrics for monitoring light-induced changes in plain yogurt during storage.
For waveguides with the polymethylmethacrylate as upper cladding, the propagation loss of the channel waveguides was measured to be 0.25 dB/cm at the monitoring light of 1550 nm.
Third, as measured by monitoring light-scattering cellular responses and cyclic nucleotide production in in vitro cell suspensions, DIFs may affect cell shape (or cohesion) and the levels of cAMP and cGMP in early stages of development [18].
Growth was tracked by monitoring light scattering at 600nm with a SmartSpec™ 3000 spectrophotometer over a period of every 24 h for 5 days.
For growth and product monitoring, light with a defined wavelength is sent into each well (excitation), whereas the backscattered light (indicator for biomass) or fluorescence (indicator for fluorescent products) is detected and analysed.
