摘要： A communication channel includes a first component having a transmitter coupled to a normal signal source, and a second component having a receiver coupled to a normal signal destination. A communication link couples the first and second components. Calibration logic provides for setting an operation value for a parameter of the communication channel, such as by executing an exhaustive calibration sequence at initialization of the link. A tracking circuit, including a monitoring function, tracks drift in the parameter by monitoring a feedback signal that has a characteristic that correlates with drift in the communication channel, and updates, or indicates the need for updating of, the operation value of the parameter in response to the monitoring function.

摘要： An AC power supply testing method upon booting a main board is provided. The testing method is applied to a main board, a microprocessor is in connection with the main board, and a relay is connected with the microprocessor, an AC power supply and a system power supply of the main board. The testing method includes steps of (1 ) configuring a system power on/off time of the microprocessor; (2 ) counting down the system power on/off time; (3 ) determining the current state of the relay; (4 ) shutting off the relay and resuming executing step (1) if the current state is ON; and (5 ) executing a power supply testing upon booting if the current state is OFF.

摘要： A locking device for locking a disc loading tray or a cover of disc drives is provided. The locking device comprises a hooking portion, a locking mechanism, a driver set and a control switch, in which the locking mechanism comprises a hook. When the hook is moved to a first position, it is engaged with the hooking portion, and when the hook is moved to a second position, it releases the hooking portion to cause the tray to be ejected out or the cover to be opened. When the driver set drives the hook to leave the first position, the hook triggers the control switch to cause the potential state in the control switch to be changed. The driver set can be accurately controlled to stop at a first time by detecting the change of the potential state in the control switch. Whereby, the driver set can obtain a longer braking distance and prevent the cam form hindering the hook to return to the first position due to the inertia of the motor or the signal delay.
摘要翻译：提供了用于锁定盘装载盘或盘驱动器盖的锁定装置。锁定装置包括钩部，锁定机构，驱动器组和控制开关，其中锁定机构包括钩。当钩子移动到第一位置时，其与钩挂部分接合，并且当钩子移动到第二位置时，释放钩挂部分以使托盘被排出或盖被打开。当驾驶员设置驱动挂钩离开第一个位置时，挂钩触发控制开关，使控制开关中的潜在状态发生变化。通过检测控制开关中的电位状态的变化，可以准确地控制驱动器组，以在第一时间停止。由此，驾驶员组可以获得更长的制动距离，并且防止由于电动机的惯性或信号延迟而使钩子阻碍钩子返回到第一位置。
