Abstract: A driving device, a light emitting diode (LED) driving device and a method thereof are provided. The driving device includes a driving unit and a plurality of selection units. The driving unit produces a driving signal to drive a light emitting diode. The selection units are coupled to the driving unit and respectively correspond to a current value. The driving unit selects one of the selection units according a first pulse width modulation (PWM) signal. The current value corresponding to the selected selection unit is taken as the current value of the driving signal. The driving unit generates a duty cycle of a second PWM signal according to the duty cycle of the first PWM signal to serve as a duty cycle of the driving signal. In this way, power consumption of the LED is reduced.

Abstract: The present invention relates to a method of near real-time band jamming prevention, which provides a vehicle controller with the ability of examining autonomously the communication band between itself and a remote guidance and control apparatus, so that the vehicle controller can judge the jamming extent suffered by the communication band between the vehicle controller and the remote guidance and control apparatus. Thereby, the vehicle controller can execute corresponding actions in accordance with the judgment result of the method of near real-time band jamming prevention according to the present invention. In particular, when multiple vehicles operate synchronously and operators of the vehicles have no time to handle at the same time, the method of near real-time band jamming prevention according to the present invention provides the vehicle controllers with the ability of judging autonomously the communication band with preferred received signal strength intensity.
