    • An analog-to-digital converter (ADC) is disclosed operable to convert a sensor signal to a digital value. A differential amplifier responsive to the sensor signal and a reference signal generates a first analog signal representing a first offset above the reference signal and a second analog signal representing a second offset below the reference signal. A first oscillator generates a first output frequency dependent on the first analog signal, and a second oscillator generates a second output frequency dependent on the second analog signal. A difference between the first output frequency and the second output frequency is generated, and the digital value representing the sensor signal is generated in response to the difference.

    • The present disclosure provides systems and methods for extending a deterministic network over a wide geographical area. According to one embodiment, an IED may transmit data frames using a deterministic frame-based communication protocol, such as EtherCAT, via a local deterministic fieldbus. A first transceiver may encapsulate the data frames for transmission over a multiplexing synchronized optical network, such as a SONET network. A second transceiver may de-encapsulate the encapsulated data frames and transmit them via a remote deterministic fieldbus, such that communication between the local and remote deterministic fieldbuses is deterministic. Accordingly, an IED may communicate with a high level of determinism and/or in real-time with various components in a power delivery system across a wide geographical area including multiple deterministic fieldbuses.
    • 本公开提供了用于在广泛的地理区域上扩展确定性网络的系统和方法。 根据一个实施例,IED可以使用基于确定性的基于帧的通信协议(诸如EtherCAT)经由本地确定性现场总线来发送数据帧。 第一收发器可以封装数据帧以在诸如SONET网络的复用同步光网络上进行传输。 第二收发器可以去封装封装的数据帧并通过远程确定性现场总线发送它们,使得本地和远程确定性现场总线之间的通信是确定性的。 因此,IED可以在包括多个确定性现场总线的广泛地理区域的电力传送系统中的各种组件以及/或实时地与高水平的确定性通信。

    • A disk drive comprising a disk, a head actuated over the disk, a read/write channel, a control processor, and a servo system is disclosed. The servo system is configured to read servo information from a servo wedge on the disk via the read/write channel, to generate first and second status information based on the read servo information, to output the first and second status information to the control processor, and to output first and second interrupt signals to the control processor, the first and second interrupt signals being spaced apart by a time delay. In response to the first interrupt signal, the control processor is configured to determine whether to release data from a host based on the first status information, and in response to the second interrupt signal, the control processor is configured to determine whether to release data from the host based on the second status information.
