The performance metric measured is the average error distance of the position of a device.
For instance, the user interface has been enhanced using gyroscope, and therefore, the visualization can be controlled by rotation or current position of a device [3].
The ideal position of a device that takes only the mechanical structure of the field into consideration can be calculated directly, and the calculated device's ideal position is the estimated position.
Network-based localization, where other nodes (whether base stations or other handsets within range) estimate the position of a device, must accurately reveal a target location within 100 meters 67% of the time and within 300 meters in 95% of cases.
The idea is to use probes similar to those used in GAARDIAN, but interconnected in such a way that the position of a jamming device can be determined by triangulation.
From airports to train stations, fast food outlets and logistics companies, much of the data was generated using GPS technology, which logs the position of a transmitting device at specific time intervals.
There were 29 management changes in 26 routine CXRs (12 changes in position of a medical device, and 17 changes in clinical management).
There were also four non-routine CXRs, which resulted in five changes in clinical management and one change in position of a medical device.
The two most common indications for non-routine CXRs were following a procedure to verify the position of a medical device and exclude complications, and for evaluation of a suspected new medical condition.
The intellectual passion that Tanne builds into the scene, and that Sawyers delivers with nuanced fervor, is all the more striking and exquisite for its subtle positioning as a device of romantic seduction.
