    • An embedded controller (EC) is a microprocessor having a firmware storage for use in a notebook computer (NB) to control keyboard, touch pad or other user interfaces. When the NB is just powered on or before the south-bridge chip (ICH) is activated, the EC is switched from a slave to a master, and the whole or part of firmware codes can be downloaded from the BIOS storage via LPC/SPI bus. Then, the whole or part of the firmware is updated using an in-circuit programming function of the Firmware Storage. Thereafter, the EC is switched back to the slave, and the NB is powered on or the ICH is activated. It is not necessary to update EC firmware corresponding to different version of BIOS when manufacturing an NB, and unexpected errors encountered during the EC self-updating can be effectively repaired to protect the EC firmware.
    • 嵌入式控制器(EC)是具有用于在笔记本计算机(NB)中使用的固件存储器以控制键盘,触摸板或其他用户界面的微处理器。 当NB上电或在南桥芯片(ICH)被激活之前,EC从从机切换到主机,并且可以通过LPC / SPI从BIOS存储器下载全部或部分固件代码 总线。 然后,使用固件存储的在线编程功能更新固件的全部或部分。 此后,EC切换回到从机,NB打开电源或ICH被激活。 在制造NB时,不必更新与不同版本的BIOS相对应的EC固件,并且可以有效地修复EC自动更新期间遇到的意外错误,以保护EC固件。

    • An electrical connector (1), connected with a cable (5), comprises an insulative housing (2) having a plurality of cavities, a plurality of terminals (3) received in the cavities, and a latching member (4) attached to the housing. The latching member has a base plate (40) and a plurality of silos (44) extending from the base plate. A diameter of a channel (48) in each of the silos is slightly larger than a diameter of a corresponding wire (50) of the cable. During assembly of the connector and the cable, the wires of the cable extend through the channels of the latching member prior to connection of the terminals and the wires.
    • 与电缆(5)连接的电连接器(1)包括具有多个空腔的绝缘壳体(2),容纳在空腔中的多个端子(3)和附接到所述空腔的闭锁构件(4) 住房。 闩锁构件具有基板(40)和从基板延伸的多个筒仓(44)。 每个筒仓中的通道(48)的直径略大于电缆的相应导线(50)的直径。 在连接器和电缆的组装期间,电缆的电线在端子和电线连接之前延伸穿过闩锁构件的通道。

    • A wireless cursor indicating device includes a first body and a second body combined with each other. The first body includes a containing space for containing a control circuit and a wireless receiver, and ends of the first and second bodies include a positioning member and a wheel, and a latch is disposed between the first and second bodies, such that the first and second bodies can be turned with respect to each other by the fixing member and wheel to define a closed status when the first and second bodies are stacked with each other or an open status when the first and second bodies are disposed alternately with each other. The first and second bodies can be disposed alternately with each other by the effect of the latch, such that a containing space is exposed to facilitate users to access or storage objects in the containing space.
    • 无线光标指示装置包括彼此组合的第一主体和第二主体。 第一主体包括用于容纳控制电路和无线接收器的容纳空间,第一和第二主体的端部包括定位构件和车轮,并且闩锁设置在第一和第二主体之间,使得第一和第二主体 当第一和第二主体彼此堆叠时,第二主体可以通过固定构件和轮相对于彼此转动,以在第一和第二主体彼此交替设置时形成关闭状态。 第一和第二主体可以通过闩锁的作用彼此交替布置,使得容纳空间暴露以便于用户访问或存储容纳空间中的物体。
