In this paper we present a online\nhandwriting recognition system for word recognition which is based on inertial\nmeasurement units (IMUs) for digitizing text written on paper. This is obtained\nby means of a sensor-equipped pen that provides acceleration, angular velocity,\nand magnetic forces...
TheBNO055class supports access in interrupt service routines (ISR's) by means of theigetmethod andw,x,y, andzbound variables. The ISR callsigetwith the name of the value to be accessed. On return the bound variables are updated with the raw data from the device. Each value is a signe...
11. The results show that SVM-FOS proposed approach achieves better accuracy in positioning which means enhancement of the navigation solution. The results shows that the proposed algorithm RMSE may be comparable to augmented KF-FOS approach, but exploring the results closely confirm that proposed ...
With the emergence of numerous low Earth orbit (LEO) satellite constellations such as Iridium-Next, Globalstar, Orbcomm, Starlink, and OneWeb, the idea of considering their downlink signals as a source of pseudorange and pseudorange rate measurements has
The corresponding location information has allowed for an efficient and effective means to enhance people’s work efficiency, relieving efforts, or even provide intelligent service that was not possible in traditional ways. Based on the above facts, location-aware services have been playing an ...

In this case, the real-time IMU data and the IMU data associated with the video data can be synchronized. For example, both sets of IMU data may contain an indication of direction using a compass heading. When both directions indicate, e.g., north, that means that the rescuer 600 is ...
mind was troubledand he could not sleep.2So the king summoned the magicians,enchanters, sorcerersand astrologers[a]to tell him what he had dreamed.When they came in and stood before the king,3he said to them, “I have had a dream that troublesme and I want to know what it means.[b...
