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...
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...

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. View Active Sensors Accessories AI-Tek...
Global surface soil moisture (SSM) datasets have been produced based on active and passive microwave satellite observations, including the Soil Moisture and Ocean Salinity (SMOS) and the Advanced Scatterometer (ASCAT) SSM products (Bartalis et al., 2007, Kerr et al., 2010, Njoku et al., ...
While passive filters excel in simplicity and linearity, active filters provide superior performance, improved signal isolation, and the ability to realize more complex transfer functions. However, this enhanced functionality comes at the cost of increased circuit complexity and power consumption. Still co...
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...
A Survey on Proactive, Active and Passive Fault Diagnosis Protocols for WSNs: Network Operation Perspective Although wireless sensor networks (WSNs) have been the object of research focus for the past two decades, fault diagnosis in these networks has received li... M Amjad,A Nabil,M Mithun,....
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 ...
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 ...
