We consider a distributed sensor localization problem where the estimation of distances between anchors (at known locations) and a target node (at an unknown location) are obtained through noisy measurements. In general, the measurements are perturbed by additive noise, interference from other devices...
in which light propagates along the circular rim of such a structure like a sphere, a disk, or a toroid by continuous total internal reflection. The sensor node is controlled via a customized iOS app. Its performance was studied in two practical scenarios: (1) real-time measurement of the ...
The Modular X- and Gamma-ray Sensor (MXGS) is an imaging and spectral X- and Gamma-ray instrument mounted on the starboard side of the Columbus module on t
So while there may be differences in the definitions of sensors and transducers, this has little impact on the ability to utilize sensors in applications. Within this book we use the simple and broad definition that a sensor measures something of interest using a variety of mechanisms, and a t...
through a comprehensive analysis and test of theApplication Programming Interface(API) services; finally, the results of the survey are summarized inTable 2. Additionally, we finish this survey through: 1) making much comparison between different related technologies, such as a comparative analysis of...
This article describes a thorough investigation into multi-sensor data fusion, which over the last ten years has been used for integrated positioning/navigation systems. In this article, different navigation/positioning systems are classified and elaborated upon from three aspects: (1) sources, (2) ...
11. The method of claim 6, wherein adjusting a phase of an energizing signal is repeated until the first phase difference between the IF calibration signal and the reference signal corresponds to a first predetermined value. 12. The method of claim 5, wherein processing the sensor signal dur...
Disclosed is an integrated imaging sensor/neural network controller for combustion control systems. The controller uses electronic imaging sensing of chemiluminescence from a combustion system, combin
1.A star sensor comprisinga detector array for viewing at least one star and outputting star data,a first median filter configured to reduce spikes in the outputted star data, and provide first filtered star data,an averaging filter configured to low-pass filter the first filtered star data an...
Many of the configurations of the SPR lightpipe sensors of this invention involve imaging of input light through the lightpipe. In one embodiment, the invention provides a first order SPR sensor system in which the sensing element is a planar lightpipe. Light coupled into the lightpipe reflects...
