Analysis of the French lightning locating system location accuracy

2015 International Symposium on Lightning Protection (XIII SIPDA), 2015
The location accuracy is one of the important parameters characterizing the performance of a lightning location system. It is also one of the most difficult to determine as the actual location of the discharge being located must be accurately known to achieve a reliable assessment of the real error.

Preliminary Study of Brake Pedal Location Accuracy

Proceedings of the Human Factors Society Annual Meeting, 1988
Three experiments of brake pedal location accuracy were conducted using 24 subject drivers. The first experiment tested the accuracy of recall of drivers for the brake pedal location of the vehicle with which they were very familiar. The second experiment examined the accuracy of recall for a brake pedal location with which they had recent practice ...

Locating Industrial Parts with Subpixel Accuracies

SPIE Proceedings, 1987
Industrial machine vision requires speed, accuracy, and low cost. The SUPERSIGHT vision system at General Motors Research locates industrial parts with high accuracy even with low-resolution video cameras. This leads to large savings in the hardware costs of subsequent image processing electronics, and considerable speed improvements over current ...

Accuracy of Track Location in Spark Chambers. I

Review of Scientific Instruments, 1961
Several spark chambers with a sensitive area of about 6×6 in. have been constructed using 0.005-in. aluminum plates and 0.25-in. glass frames as spacers. These were tested with cosmic rays, using neon, argon, and neon-argon mixtures as the filling gas. A spark gap triggered by scintillation counters was used to apply a high voltage pulse to the plates.

Real-time vehicle location with desired accuracy

ITSC 2001. 2001 IEEE Intelligent Transportation Systems. Proceedings (Cat. No.01TH8585), 2002
Magnetic markers are provided on automated highway system for lateral control of vehicles within a lane. We propose a pseudo-noise (PN) code to be carried by the magnetic markers. The PN code will be used by vehicles for range measurement. Every vehicle is provided with the code layout on the road with respect to the physical location of every binary ...

Accuracy Verification of Location Base Protocol Mechanism

2011 7th International Conference on Wireless Communications, Networking and Mobile Computing, 2011
Operation of indoor and outdoor localization cannot be combined because the techniques and mechanisms cannot be shared or worked together. Consequently, they are not integrated to support seamless mobility in the application level, e.g., still discontinuity of service when the mobile users move from indoor to outdoor and vice versa. This paper presents

Fitbit Accuracy Depends on Activity Pace and Placement Location

2020
This study is designed to measure the concordance of step counts recorded by Fitbit activity trackers when the devices are placed on multiple locations of the body and while subjects climb stairs at fast, slow, and medium paces. Nine participants wore 5 Fitbit trackers concurrently while performing the stair-climbing activity.

Accuracy of forecast of mine tremors location

Mining Science and Technology (China), 2009
The Upper Silesian Coal Basin is one of the most active mining areas in the world in respect of seismicity. Underground mining in this area takes place in a special environment with a high degree of risk of unpredictable event occurrence. Especially dangerous are phenomena that occur during the extraction of deposits at great depths in the environment ...
