    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: A multi-layer circuit board includes a first layer including a first trace, a second layer connected to the first layer and including a second trace, and a stubless interconnect positioned through the first layer and the second layer. The stubless interconnect includes a body that is electrically insulative, and a bridge trace that is electrically conductive and connected to the body, the bridge trace extending from the first trace to the second trace to electrically connect the first trace and the second trace.

    Abstract: A system to protect signal integrity includes a circuit board having a secure portion and a non-secure portion. The secure portion includes a protected circuit operable for storing security relevant data, and a secure portion power-supply element. The non-secure portion includes an unprotected circuit and a non-secure portion power-supply element corresponding to the secure portion power-supply element. The secure portion and the non-secure portion element are separated by an isolation gap. A coupling element bridges the isolation gap between the secure portion and the non-secure portion. The coupling element is electrically connected to the secure portion power-supply element within the secure portion and electrically connected to the non-secure portion power-supply portion.
