The length of the transformation line (12.1) is such that the imaginary component of its impedance is the same with and without an object present. USE/ADVANTAGE - Operates continuously and can detect presence of metallic and non-metallic objects even under conditions of high humidity and fouling...
The sensor generates a signal indicative of the presence or absence of the ferrous object. In manufacturing a preferred spatial position of the null point with respect to the Hall-effect sensor is defined by adjusting the field strength of at least one of the opposed magnets. 展开 ...
The proximity sensor is a crucial sensor in any Android device, as it allows the device to detect the presence of nearby objects, such as when you place the device next to your ear during a call. If the proximity sensor is not working correctly, it can result in problems such as the s...
In some embodiments, the sensors have a measurement zone that has a volume less than the volume of the sample cha... T Chen,A Ghesquiere 被引量: 26发表: 2007年 Improved microfluidic sensor units to detect the presence of an analyte in a sample-fluid The present invention relates to ...
the promoter layer incorporates an oxide that is a p-semiconductor at the sensor working temperature. An independent claim is also included for a process to operate the sensor to detect the presence of unburned hydrocarbons in automotive exhaust gases. 展开 ...

A fluid-driven sensor for detecting and indicating the presence of a foreign object in the path of a fluid medium having a cylindrical vortex generation chamber, a supply port for introducing a driving fluid into the generation chamber, a vortex egress port communicating with a central portion of...
of hi To demonstrate the feasibility of our non-destructive diffractive defect detection framework, we designed a proof-of-concept single-pixel diffractive terahertz sensor that can effectively detect pore-like hidden defects within silicon materials; these defects are not visible from the outside. ...
