Abstract: Devices, methods, and systems for localizing a fault on a live cable are described herein. One system includes a wire fault localizer configured to receive current information from a location where direct current is applied to a cable comprising a number of loads, receive additional current information from at least two additional locations on the cable, wherein one of the at least two additional locations is on a source side of the cable and one of the at least two additional locations is on a load side of the cable, determine a fault resistance of the cable based on the received current information and received additional current information, and determine a fault distance on the cable based on the fault resistance.

Abstract: Apparatus for determining concentration of a targeted gas in environmental air, the apparatus includes a non-dispersive infrared (NDIR) sensor, a pressure sensor coupled in fluid communication with an interior of the NDIR sensor; and a processor. The processor is configured to receive pressure data from the pressure sensor based on gas pressure within an interior of the NDIR sensor, receive a target-gas concentration signal from the NDIR sensor, and produce a pressure-compensated concentration signal based on the target-gas concentration signal, a predetermined reference pressure and the pressure data from the pressure sensor.
