    摘要: A unique double inversion buffer has a first means to invert and isolate the digital input signal, a second means to reinvert and further isolate the input signal, and an output means including an output transistor 94. The double inversion buffer is configured with active pull-down means on the output transistor 92. The high-to-low propagation delay time and the low-to-high propagation delay times through the double inversion buffer and reduced by use of the active pull-down means. Rapid turnoff of the output transistor is accomplished by coupling a transistor to its base to instantaneously turn it off. In a preferred embodiment, a clamping circuit 201 is used to hold the output voltage at a maximum predetermined level to further reduce the time it takes to reduce the output voltage to the logical "0" state.

    摘要: The present invention combines in either a logical AND function of N logical input signals, where N is a selected positive integer greater than or equal to 1, and provides programmably, either a direct AND output signal or a NAND output signal. The invention accomplishes this using a minimum number of components in the data path, between the logical input leads and logical output leads. A minimum of components in the data path reduces the propagation delay introduced by the circuit. The invention accomplishes this by providing two AND gates connected to the same set of N logical input signals. The output signal of one AND gate is inverted by an inverter with an enable/disable input lead. The output signal of the other AND gate is inverted twice by two inverters. The second inverter has an enable/disable input lead. Means are provided for exclusively enabling one or the other of the two inverters with an enable/disable input lead. Thus, either the once inverted signal is provided to the output lead or the twice inverted signal is provided to the output lead.

    摘要: Granting permissions for attributes in a distributed data store involves implementing a federated control system. The system can include dynamic permissions granted to content blobs. Acknowledgment of dynamic permissions facilitates identification of users that receive content to enable restoring data on a machine following data loss. Acceptance of dynamic permissions can further facilitate automatic updates to data, or providing content blobs in response to changes in user attributes.
