Abstract: The present disclosure relates to a zone controller (ZC) boundary handover management method for coupled trains. The coupled trains include a master-control train for obtaining movement authorization of ZCs and multiple non-master-control trains by coupling. The method includes: one ZC determines a safety positioning zone of a train according to a position message transmitted by the train, calculates time delay protection and a time delay protection sequence thereof and transmits a message to an adjacent ZC; the ZC creates a train set according to the position message of the train therein and the message transmitted by the adjacent ZC, calculates a valid movement authorization and variable information for the master-control train, concatenates adjacent movement authorization and variable information together and transmits the concatenated movement authorization and variable information to the master-control train as a running basis.

Abstract: A temporary train speed restriction management method and system. Temporary speed restriction instructions are managed by adopting a uniform session management framework. The temporary speed restriction instructions in a session are uniformly processed in a session closing stage. The availability of a communication link is detected. The method and system performs life cycle management on the temporary speed restriction instructions by adding a timeliness mechanism for the message.

Abstract: A MEMS actuator assembly package features a number of drop test resistant mechanisms is disclosed. These mechanisms are used to decelerate and finally stops the heavy load of the image sensor attached to the MEMS actuators along all six directions of the in-plane and out-of-plane axes (±x, ±y, ±z). The MEMS actuator assembly package comprises first and second sets of flexible stoppers attached to the MEMS actuator along with a set of hard stoppers that engage in a sequential manner with the moving mass of the loaded actuator to decelerate it, bringing it to a complete stop when exposed to mechanical shock along the four directions of the in-plane axes (x and y). When the assembly package is exposed along the positive and negative direction of the z-axis, the moving mass is stopped by features built in the package.
