These autonomous sensor networks commonly include passive sensors such as infrared, acoustic, vibration, and magnetic nodes.
Manual therapists commonly use passive intervertebral motion (PIVM) assessment within physical examination.
We assume commonly used passive RFID tags that employ backscatter modulation to convey information back to the reader [25].
Other commonly used passive measurements include time-of-arrival (TOA), time difference of arrival (TDOA), frequency of arrival (FOA), and combinations thereof (e.g. again, see [1] and references therein).
Dams commonly allow passive or active downstream drift of fish, but obstruct upstream migration.
Current commercial systems allow up to four-way sorting based on fluorescent emission with a throughput of ∼30,000 cells/s.Magnetic-activated cell sorting (MACS) is a commonly used passive separation technique.
Tenax sampling tubes are not commonly used in passive mode and so the VOC sampling rates were unknown.
Active vibration isolation systems are less commonly used than passive systems due to their associated cost and power requirements.
Classical models, developed for corrosion-resistant alloys, assume surface layers (commonly known as passive layers) are inherent to the metals/alloys.
The first grating demultiplexes a 300 nm wide band and drops optical channels at 1490 and 1550 nm, commonly used in passive optical networks.
Despite these limitations, laboratory data are commonly used for passive disease surveillance.
