Abstract: Systems and methods are provided for increasing driver awareness of external audible and visual alerts. The external alerts may be detected by external sensors of a vehicle. Systems may use internal sensors to determine whether a driver of the vehicle appears aware of the external alert or whether the external alert is detectable inside the vehicle.

The internal alert may be one or more of a visual alert, an audible alert, or a tactile alert.

Abstract: Signal transducers in electrical communication with shorted leads of current transformers are used to provide monitoring and protection functions to an electric power delivery system. Differential protection is performed by comparing a predetermined threshold against a voltage signal from series-connected leads of signal transducers in electrical communication with shorted leads of current transformers. The signal transducers may be Rogowski coils. Signal transducers in communication with shorted leads may be used to improve safety and increase performance of the current transformers by decreasing susceptibility to saturation.
