20130177041 | SYSTEM AND METHOD FOR MONITORING IN REAL TIME THE OPERATING STATE OF AN IGBT DEVICE - A system and method are provided for monitoring in real time the operating state of an IGBT device, to determine a junction temperature and/or the remaining lifetime of an IGBT device. The system includes a differential unit configured to receive a gate-emitter voltage characteristic of the IGBT device to be measured and to differentiate the gate-emitter voltage characteristic to obtain pulses correlating with edges formed by a Miller plateau phase during a switch-off phase of the IGBT device. The system also includes a timer unit configured to measure the time delay between the obtained pulses indicating the start and end of the Miller plateau phase during the switch-off phase of the IGBT device, and a junction temperature calculation unit configured to determine at least one of the junction temperature of the IGBT device and/or the remaining lifetime of the IGBT device based on the measured time delay. | 07-11-2013 |

20140044494 | RETAINING DEVICE - A retaining device is described. The retaining device has a retaining barrier, wherein the retaining barrier has a support frame including at least three arms. The support frame is adapted to assume a non-operating closed configuration and an operating radial configuration. In the operating radial configuration, each arm is oriented along a respective radial direction; in the non-operating closed configuration, at least a first arm is oriented along the same radial direction of the operating radial configuration and the remaining second arms are oriented along a direction substantially parallel to said radial direction of said at least one first arm. | 02-13-2014 |
