A cloud platform-based garlic crop recognition method by coupling active and passive remote sensing images includes: firstly, obtaining an optical satellite remote sensing image based on phenological characteristics of garlic, and constructing a decision tree model for optical image recognition of the ...
Passive sensors use naturally emitted light from the sun. Without the sun, there wouldn’t be passive remote sensing. As you’re about to find out, there arehundreds of remote sensing applicationsthat use passive and active sensors. But first, let’s dig a bit deeper into both types of re...
Shared access between sensing and communications has never been demonstrated experimentally in the spectrum above 100 GHz. This is not without reason. Current spectrum policies prohibit transmissions in passive bands, even for experimental purposes. Additionally, a self-adaptive wireless link requires th...
Schematic diagram of the joint active–passive electrolocation algorithm for multiple localizations. Full size image Although this paper only discusses the localization of an aluminum cylinder as the target object in fresh water, and due to the different conductivity of water, the response of the sam...
Dynamic metasurfaces are promising new platforms for 5G communications, remote sensing, as well as beam steering in Light detection and ranging (LiDAR) systems, where the insertion of active elements can break the fundamental limitations of passive and static systems....
FIG. 2 is a block diagram of an active RFID tag or WiFi client and wireless access point according to an embodiment of the invention; FIG. 3 is a block diagram of a combined passive and active RFID tag, tag reader, and wireless access point according to an embodiment of the invention;...
Due to its excellent characteristics, such as low cost and high stability, the space-domain passive FCRD technique has attracted more and more interests and been widely used for many sensing applications, such as strain sensing25, refractive index detection24, magnetic field sensing27 and so on....
Magnetic sensors are widely used in our daily life for assessing the position and orientation of objects. Recently, the magnetic sensing modality has been introduced to electronic skins (e-skins), enabling remote perception of moving objects. However, th
Therefore, there is a need for bit-based passive and active radiation sensors for improved estimation of formation properties during drilling of a wellbore. SUMMARY The present invention provides a drill bit in accordance with claim 1. The present disclosure provides a drill bit that includes a bi...
CM current emanating from the power stage then gets recirculated by the low shunt impedance of the filter Y-capacitors (both active and passive), thus preventing noise from reaching the LISN. 3. Based on the amplification of the effective Y-capacitance, AEF allows reduction of the CM choke ...
