Abstract: Arc fault detection modules for vehicles intended to supervise circuits and detect arc fault conditions in both alternating current and direct current circuits. A number of these arc fault detection modules may be integrated into a vehicle's electrical system in strategic locations. Each arc fault module contains sensing capabilities for monitoring the circuit, and may also include signal conditioning capabilities, processing capabilities for determining the occurrence of an arc fault, contactors for disabling the supervised circuit, and communications capabilities to interact with other vehicle components and telematics systems. As a result arc fault detection odules can be customized to leverage existing features of a vehicle's electrical system or to provide fully redundant arc fault protection.

Abstract: Multi-layer capacitor divider voltage sensors include a plurality of voltage sensor conductive layers having sensor to ground interface surfaces. Respective voltage sensor conductive layers are connected to each other and sensor output voltage Vs by continuations of material forming the interface surfaces extending therebetween. The voltage sensors also include a plurality of conductive ground layers connected to electrical ground, the ground layers interleaved with the voltage sensor conductive layers so that a conductive ground layer resides between adjacent conductive voltage sensor layers. A first voltage sensor conductive layer (closest to a line conductor) is electrically connected to the other conductive voltage sensor layers and output voltage Vs and has a sensor to conductor interface surface with a corresponding interface area.

Abstract: A number N of position sensors, each associated with one of N shift rails in a shift rail transmission system, wherein the set of N sensors is divided into subsets and each subset is provided a common reference from a control module; and a processing component that determines from data from each sensor whether the shift rail associated with that sensor is in a position of engagement of a first gear, a position of engagement of a second gear, or in a neutral position. Further, providing a first common reference to a first set of shift rail position sensors; providing a second common reference to a second set of shift rail position sensors; receiving sensor data from each position sensor; determining that the data from the first set of position sensors is unreliable; and operating a transmission using only the gears related to the position sensors in the second set.
