    • A latch includes three circuits. The first circuit drives a first output (QB) to a first level when a first input (D) and a first clock phase (CK) are both low, to a second level when D and CK are both high, and provides high impedance (HI-Z) when different logic levels are applied to D and CK. The second circuit drives a second output (Q) to the first level when a third input (DB) and a complimentary clock phase (CKB) are both low, to the second level when DB and CKB are both high, and provides HI-Z when different logic levels are applied to DB and CKB. The third circuit maintains voltages of Q and QB when the first and second circuits provide HI-Z at Q and QB. Odd-number dividers constructed with such latches produce 50% duty cycle operation without restricting output pulse widths to integer multiples of input periods.
    • 闩锁包括三个电路。 当D和CK均为高电平时,当第一输入(D)和第一时钟相位(CK)均为低电平时,第一电路将第一输出(QB)驱动到第一电平,并提供高阻抗( 当对D和CK应用不同的逻辑电平时,HI-Z)。 当DB和CKB均为高电平时,第三输入(DB)和互补时钟相位(CKB)均为低电平时,第二电路将第二输出(Q)驱动到第一电平,并提供HI-Z 当DB和CKB应用不同的逻辑电平时。 当第一和第二电路在Q和QB提供HI-Z时,第三电路维持Q和QB的电压。 使用这种锁存器构造的奇数分频器可以产生50%的占空比运算,而不会将输出脉冲宽度限制为输入周期的整数倍。

    • A system and method are provided for activating inactive software options pre-installed on a device upon initialization of the device and thereby preventing installation during device operation. The invention includes receiving a request from a user at a centralized facility for access to an inactive option resident on the device. After validation of the request, an option-specific activation key or code is generated at the centralized facility using data from at least one of a user identifier, a system identifier, a host identifier, a use period identifier, and the selected option. The activation key is then transmitted from the centralized facility to the device whereupon only during initialization or reboot of the device is access to the inactive option automatically granted. The limiting of access to the inactive option until device initialization ensures that option enablement is prevented during device operation.
    • 提供了一种系统和方法,用于在设备初始化时激活预先安装在设备上的非活动软件选项,从而防止在设备操作期间的安装。 本发明包括在集中式设备处接收来自用户的请求,以访问驻留在该设备上的非活动选项。 在请求验证之后,使用来自用户标识符,系统标识符,主机标识符,使用周期标识符和所选择的选项中的至少一个的数据在集中式设备处生成特定于选项的激活密钥或代码。 然后,激活密钥从集中式设备传输到设备,因此仅在设备的初始化或重新启动期间才能自动授予对非活动选项的访问。 在设备初始化之前限制访问非活动选项可以确保在设备操作期间防止选项启用。
