The system includes an interventional medical device (214) insertable into the region of interest, and a sensor (215) attached to a portion of the interventional device, the sensor being configured to convert an ultrasonic wave from an ultrasound imaging probe (211) to a corresponding electrical...
Active (Hall Effect) AI-Tek has dedicated years of experience and time to designing and manufacturing Hall Effect sensors for Automotive, Military, Petro-Chem, Industrial, Rail, Power Generation and Marine and put that know-how into every sensor we make. ...
Light detection and Ranging (LiDAR) is an active sensor that measures ground height. Using light from an airplane or helicopter platform measures the time it takes to bounce back to the sensor. From this, you can createDigital Surface Modelswhich are useful in forestry. Active remote sensing ha...
The three components of microwave remote sensing (sensor-scene interaction, sensor design, and measurement techniques), and the applications to geoscience are examined. The history of active and passive microwave sensing is reviewed, along with fundamental principles of electromagnetic wave propagation, an...
Active wheel-speed sensors require power to operate, whereas passive units do not. There are two types of active wheel-speed sensors: a Hall-effect sensor and a magneto-resistive sensor. A Hall-effect sensor requires either a toothed or magnetic ring to generate a voltage signal, whereas a ...

This study investigates the consistency of two global satellite-based SSM datasets based on microwave remote sensing observations from the passive Soil Moisture and Ocean Salinity (SMOS; SMOSL3 version 2.5) and the active Advanced Scatterometer (ASCAT; version TU-Wien-WARP 5.5) with respect to LSM...
For instance, Sentinel-1 is a satellite mission with an active radar sensor and has been used to monitor mowing events on grasslands (Tamm et al., 2016). With an ever-increasing volume of remote sensing data and higher spatial, temporal, and spectral resolutions, we hypothesize that it is ...
Role of Active and Passive Electronic Components in a Circuit Electronic components, both active and passive, are lifeline of anyPrinted Circuit Board assembly. They both play vital roles in the functioning of any electronic device. Electronic Components are intended to be connected together, usually...
mm-Wave Active and Passive Devices Thanks to the technology scaling, the cut-off frequencies of MOS transistors reach an f T of 250 GHz and f MAX of 300 GHz in 40-nm CMOS technology. On top of offering high-speed transistors, the advanced CMOS technology usually provides ... D Zhao,P...
