args是这个信号量集数据结构中要通过IPC_SET来更新的值(在这个例子中会有解释)。
Args are the values to be updated in the semaphore set data structure through this IPC_SET (explained in the sample).
为了对信号量集数据结构进行初始化，可以使用IPC_SET命令来调用semctl系统调用。
In order to initialize the semaphore-set data structure, use the semctl system call with the IPC_SET command.
通过脑电图仪数据分析，科学家们来判断大脑的哪一部分控制着刹车信号，相应的以此来改进这个系统。
This data enabled the scientists to analyse the EEG information to determine which parts of the brain are key to braking. They improved the detection system accordingly.
