Other mechanical detection devices, based on a technology called electron capture, also rely on odors and can be falsely set off by some perfumes, shoe polishes and industrial chemicals.
Furthermore, a simple ammonia sensing device based on the composite film showed high sensitivity and a low limit of detection.
The study was carried out in a cold flow model especially designed for the fluid-dynamic analysis of the system equipped with a recently developed residence time measurement device based on the detection of ferromagnetic tracer particles through inductance measurement.
Clearly, an imaging device based on positron detection that could be placed into the surgical field would be highly desirable.
The field-deployable instrument, consisting of an 830-nm diode laser for excitation and an avalanche photodiode (APD) for detection, is a fully integrated, tunable, "point-and-shoot" Raman device based on solid-state acousto-optic tunable filter (AOTF) technology.
A bio-detection method and devices based on RF electric signals and MEMS are proposed and demonstrated by a label free method.
In order to enable location independent mental stress evaluation, the development of portable sAA activity monitoring devices based on optical detection method was investigated [ 64– 64].
Screening devices based on diamond type detection can be used to make a distinction between diamonds that are certainly natural and diamonds that are potentially synthetic.
Currently, anomaly detection methods include anomaly detection based on classification, anomaly detection based on the nearest neighbor method, anomaly detection based on clustering, statistical anomaly detection, anomaly detection based on information theory, spectral theory anomaly detection, and so on [1].
