20120299573 | AC/DC Current Transformer - A single-coil, toroid-type current transformer circuit for detecting both AC and DC current. The current transformer circuit may include a current transformer and an oscillator electrically connected to the current transformer. The current transformer circuit may further include an open and short CT detection circuit electrically connected to the oscillator for facilitating determination of the connection and stability state of the current transformer. A processor may be electrically connected to an output of the open and short CT detection circuit for performing a series of operations on signal data generated by the open and short CT detection circuit and manipulating the operation of an electrical power system accordingly. | 11-29-2012 |
20140361761 | AC/DC CURRENT TRANSFORMER - A method for processing output from a current transformer comprising deriving signal data from the output; converting the signal data from analog to digital format; removing a carrier signal from the signal data; squaring the signal data; and performing a recursive RMS algorithm on the signal data. | 12-11-2014 |
20150048840 | NEUTRAL GROUNDING RESISTOR MONITOR - A device for monitoring a neutral grounding resistor (NGR), including first and second NGRs electrically connected in parallel, a rectifier circuit electrically connected in series with the second NGR and a voltage source and a logic resistor electrically connected in series with the second NGR. A logic circuit measures current passing through the logic resistor and determines the resistance of the first NGR based on the measured current and the resistance of the second NGR. As such, a failed-open or failed-short condition of the first NGR may be identified based at least in part on the determined resistance of the first NGR. | 02-19-2015 |

20140168830 | THREE-PHASE GROUND FAULT CIRCUIT INTERRUPTER - A three-phase GFCI device is disclosed. The three-phase GFCI device may include contactors, a contactor control module configured to cause the contactors to close during normal operation of the GFCI device and open based on receiving a fault signal, a current detection module, a transient suppression module, a miswire detection module, a ground-fault test module, a ground load detection module, and a fail-safe module. In some examples, the GFCI device may include the stated modules in accordance with the UL 943C standard. | 06-19-2014 |

20080263966 | Continuous curve panel structure - A system for securing building fascia panels along an edge following a locus. There is provided a system for securing building fascia panels along an edge following a locus. The system comprises a rod shaped to define the locus and a plurality of tabs, each outwardly extending from a corresponding sleeve. The sleeves are pivotally supported in adjacent fashion on the rod to define the edge. The sleeves and corresponding tabs when supported on the rod are configured so as to securely receive, on alternating tabs, sets of panels which meet along the edge. The relative angle between the adjacent tabs on the rod defines the angle between the sets of panels secured to those tabs. | 10-30-2008 |
