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...
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 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...

Mattrazzo 发明人: DC Mattrazzo 摘要: One or more sensors may be used to detect a user's presence at a listening device. Control logic may receive signals from the sensor(s) and may perform an audio related action based on the user's presence or non-presence....
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. ...
In a preferred embodiment, an object orientation sensor device, including: a first LC tag disposed at a first selected location in the object; a driver/reader circuit disposed so as to detect the presence of the first LC tag when the object is in a first orientation and to not detect the...
Potential mechanisms that can be used to detect the presence of an object are: inductive [21], optical [19], ultrasonic [20] and capacitive [15]. The inductive mechanism generates an electromagnetic field and detects the eddy current losses when ferrous and nonferrous target objects enter the ...
英语阅读理解一篇Do you forget to turn off the lights and heaters when you go out of a room?In 2040 it will not matter.They will turn themselves off and on again when you return.A sensor will detect the presence of a human and turn the systems
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...
