Abstract: An induction heating cooker and a control circuit therefor are provided. The cooker includes a switch element and an inductive coil, which is coupled between a power voltage and a first terminal of the switch element. A second terminal of the switch element is coupled to a common voltage. The control circuit includes first and second comparators and a pulse generator. The first comparator receives voltages of two terminals of the inductive coil and thus outputs a trigger signal. The second comparator receives a reference voltage and a voltage of the first terminal of the switch element, and enables a fading signal when the voltage of the first terminal is higher than the reference voltage. When the trigger signal is enabled, the pulse generator outputs a pulse to control the switch element. When the fading signal is enabled, the pulse generator reduces a pulse width of the pulse.

Abstract: Predicting waiting passenger count and evaluation. The present invention provides to a dispatching support system in order to help bus dispatchers or operators make better instructions or decisions, by providing short-term passenger flow prediction. The dispatcher finds the predicted passenger flow and obtains accurate and useful information from the predicted passenger information, such as, bus status, bus location congestion level on the buses, and passenger oriented Key Performance Index, such as, passenger weighted waiting time. Based on this passenger information, dispatchers can make better decisions and instructions.
