A system and device for detecting insulation defects in a cable are provided. The system and device include using signals received from sensors to detect a partial discharge caused by insulation defects in a cable. The system is passive, without signals being injected into system cables, and may use one or more sensors, data acquisition systems, gateway devices, and monitoring stations and is based on detecting partial discharge from insulation defects and reporting the detection when it occurs.

A device and method for detecting and locating defects in a cable are provided. The device and method may include using sensor feedback to determine that an insulation defect exists and to calculate the location of the insulation defect in a cable. The method may include performing principle component analysis to determine whether an insulation defect occurs and using extracted data to determine the location of the insulation defect.

A method and system for detecting defects in a wire or wire harness includes a pair of sensors wrapped around the wire or harness, a data acquisition device for monitoring pulses in the signal produced by the sensors around the wires, and a diagnostics engine. The diagnostics engine includes an analysis module to determine features of the signals captured by the data acquisition device and a decision module for determining whether the pulse represents a defect in the wire, and the location of the defect. The system operates passively and can be used to monitor the wires while they are in use for carrying signals or current and does not require disconnecting the wires to be monitored.

This invention provides a method for contactless fingerprint detection and verification comprising illuminating a fingerprint and directing a reflected light through an imaging system using liquid crystal panels and birefringent elements to polarize the light. A plurality of polarized images are captured and used to calculate the depth of structural features on the fingertip. A means to generate a two-dimensional rolled equivalent image of the fingerprint is also provided which may then be used for verification and authentication. The invention also provides an imaging system for carrying out the method.

A system includes a sensor housing having a base portion, a lid portion, and a joining portion. The joining portion is configured to be wrapped around at least a portion of an electrical wire. The lid portion includes one end detachably coupled to a first end of the base portion and another end coupled to a second end of the base portion via the joining portion. A flexible coil sensor is disposed in the sensor housing; bonded substantially along the base portion and the joining portion and configured to generate a signal representative of a fault in the electrical wire. A processing device is disposed in the sensor housing and configured to detect and locate a fault in the electrical wire in response to the signal representative of the fault in the electrical wire generated by the flexible coil sensor.

Systems and methods for generating a collector flashover alert by passive monitoring of a generator are provided. One method includes receiving, by a computing device, signals from a current transformer coupled around an exciter cable connected to a generator collector assembly, determining, by the computing device, when a spark has occurred in the generator collector assembly based at least in part on received signals from the current transformer, generating an indication that a spark has occurred in the generator collector assembly when it is determined that a spark has occurred in the generator collector assembly, and generating a flashover alert based at least in part on the generated indication that a spark has occurred in the generator collector assembly.
