Abstract: A fiber-optic switching system is provided which includes an optical fiber switch having first and second optical fiber portions and an electrically-controlled actuator. The first and second optical fiber portions are spaced apart with a gap between the portions that is sized to allow for light signal coupling between the optical fiber portions in a signal-passing state of the switch. The electrically-controlled actuator is coupled to transition the switch between the signal-passing state, where the light signal is allowed to pass between the optical fiber portions, and a signal-non-passing state, where the light signal is prevented from passing between the optical fiber portions. The electrically-controlled actuator includes an electroactive material exhibiting a physical change with change in an applied electrical field, where the physical change facilitates transitioning the optical fiber switch between the signal-passing and the signal-non-passing states.

Abstract: One aspect is a method that includes identifying a substantially uniform distribution of signal vias for a multi-layer circuit board based on a design file defining a layout. A signal via pitch is determined as a center-to-center distance between a neighboring pair of signal vias. The signal via pitch is compared to a target minimum drilling distance. A ground via is identified proximate the neighboring pair of the signal vias. Based determining that the signal via pitch of the neighboring pair is less than the target minimum drilling distance, at least one of the signal vias is positioned closer to the ground via such that after the positioning, the signal via pitch of the neighboring pair meets or exceeds the target minimum drilling distance. The design file is modified to include the positioning of the signal vias and is transmitted over a network to support circuit board manufacturing operations.

Abstract: An apparatus and method may detect and reduce noise on data busses by adjusting the phase of the input/output (I/O) signals in a controlled, predictable manner. The control may allow a maximum data rate to be achieved. In one embodiment, an algorithm used to determine phase change data may be handled by a feedback loop and may be dynamically adjusted. The system may detect noise on rails and critical signals for logging in call home data. The system may maintain a database of settings as a function of a workload. The system may be used in the field as the workload changes to determine that a signal has reached a first threshold. In response to determining that the signal has reached the first threshold, an alert is initiated. A system may determine that the signal has reached a second threshold. In response to determining that the signal has reached the second threshold, the signal may be coupled to logic circuitry.
