| 20080245980 | Monitoring system for turbine engine - A monitoring system for a gas turbine or other elevated temperature environment is provided. The system has one or more photonic crystal fibers for capturing and transmitting light to an imaging camera for generation of an image. The photonic crystal fibers can be formed from a sapphire cladding. The photonic crystal fibers can be band gap fibers. The photonic crystal fibers can be arranged in a bundle, including an array or a linear bundle. | 10-09-2008 |
| 20080247702 | Fiber optic generator condition monitor - A condition monitoring system for use in monitoring a generator. The condition monitoring system includes a sensor including an ion chamber located inside the generator for sensing particulates inside the generator. The sensor provides an electrical sensor output to an output converter that is also located inside the generator. The output converter converts the electrical sensor output to a light signal output which is transmitted out of the generator. An energy conversion device is located within the generator for receiving light energy from a light source outside of the generator and converting the light energy to electrical energy for powering the sensor and the output converter. | 10-09-2008 |
| 20080298428 | Temperature monitor for bus structure flex connector - A temperature monitor for monitoring plural locations on an electrical bus structure. The temperature monitor includes an infrared sensor for receiving infrared energy from a plurality of discrete predetermined locations on the bus structure, a first member defining a stationary first mask, a second member defining a rotating second mask, and a drive member driving the second member in rotation relative to the first member. Rotation of the second member relative to the first member defines an aperture translated across the first mask member to provide a moving line-of-sight that extends from the sensor and that scans to each of the discrete predetermined locations on the bus structure. | 12-04-2008 |
| 20080310804 | System to monitor a structure within an outer casing of a gas turbine engine - A system is provided to monitor a structure within an outer casing of a gas turbine engine. The system may comprise an optical fiber bundle, a fiber bundle palette and a camera palette assembly. The optical fiber bundle may have first and second ends. The first end is adapted to pass through a bore in the outer casing of the gas turbine engine so as to be positioned adjacent the structure within the gas turbine engine casing to be monitored. The fiber bundle palette is adapted to be located outside of the engine casing to receive the second end of the optical fiber bundle. The camera palette assembly comprises a fixture movable relative to the fiber bundle palette and a first camera mounted to the fixture. The first camera is adapted to be positioned adjacent to the second end of the optical fiber bundle so as to receive electromagnetic radiation received by the first end of and transmitted through the optical fiber bundle. | 12-18-2008 |
