    Abstract: Proposed are a synchronous braking control method and system for carriages of a train, that are related to the field of electrical control. The synchronous braking control system includes a main controller, an electric energy conversion controller, and a shunt. During actual braking, the main controller obtains a real-time speed and real-time mass of the train, and determines whether the real-time speed is greater than a set speed. If not, the train is directly braked in a mechanical friction braking mode. If yes, an exciting current of a synchronous brake in each of the carriages of the train is adjusted by adjusting an input voltage of the synchronous brake, and unit braking forces of the carriages are controlled equal by using the adjusted exciting current, thereby realizing synchronous constant deceleration braking of the carriages.

    Abstract: A controller for a switching mode power supply includes two semiconductor chips. The first semiconductor chip has a high-voltage startup transistor coupled to a high voltage supply input terminal and configured to provide a charging current in a startup phase or protection mode of a switching mode power supply (SMPS) and to provide substantially no current in a normal operation phase of the SMPS. The second semiconductor chip has a control circuit for controlling the switching mode power supply. The second semiconductor chip also has first and second on-chip high-voltage resistors coupled to the high-voltage supply input terminal and the high-voltage startup transistor in the first semiconductor chip. The first and the second on-chip high-voltage resistors are configured to provide a voltage and a current related to a voltage at the high-voltage supply input terminal.

    Abstract: An apparatus for developing portable packet processing applications on network processors includes a docking platform which provides a common interface for individual packet processing applications to be plugged into the network processing environment. Each application interacts with the docking platform through the common interfaces provided by the latter. The docking platform interacts with the other modules inside the system to accomplish the requests from the application. In this manner, the applications become “shielded” from the implementation details of the underlying hardware. The applications need not change when the network processor hardware features are changed. It therefore provides a universal packet processing programming environment in which applications can execute in a portable and flexible manner in various hardware architectures.
