-sensor output of three data:X*sin (THETA/2)Y*sin (THETA/2)Z*sin (THETA/2)sin (THETA/2) is a RV order of magnitude. RV is in the same direction as the Axis rotation. RV of three values, with cos (THETA/2) make up a four-tuple. RV The data has no units, and the coordinate system used is the same as acceleration. Example:Sensors_event_t.data[0] = X*sin (THETA/2)SENSORS_EVENT_T.DATA[1] = Y*sin (THETA/2)SENSORS_EVENT_T.DATA[2] = Z*sin (THETA/2)SENSORS_EVENT_T.DATA[3] = cos (THETA/2)GV , LA and the R

frequencies may be caused by interference with each other to make the picture similar to the phenomenon of water ripple. This phenomenon more than now Sitronix IC, their home IC in order to do the power is relatively small, will generally be the default crystal oscillator frequency is set relatively low, so in the semi-illuminated state often appear this phenomenon. Improvement measures: Change the crystal frequency and refresh frequency look at the effect, because the crystal oscillator after

Air safety experts, are you still worried about terrorists or the use of high-power laser pens to shake the eyes of pilots while the plane is taking off and landing?

involved will have to invest for decades without any corresponding revenue. There are already some device-related service companies that have difficulty meeting their revenue targets, but can't change them because they're afraid of provoking a huge customer base.Brody believes that the solution to the cost of IoT management and revenue is not a unified approach, is distributed, edge-based cloud computing. If the data center is the center of the network, then PCs, smartphones, and other devices

Currently, in the field of smartphone development, there are three major operating systems: Symbian, Windows Mobile (Windows), and Linux. Palm is out of the game and you don't have to worry about it. There are also two camps: The j2's camp (cross-operating systems, including windows) and the. net cf camp (only running on Windows, hereinafter referred to as. net ). The development languages on these platforms include:Symbian: C ++, Java, PythonWind
