| 20090063063 | Preventive Maintenance Tapping and Duty Cycle Monitor for Voltage Regulator - The life of load tap changer contacts is monitored by detecting an arcing event; identifying arcing surfaces involved in the arcing event; calculating a per-unit loss of life for the identified arcing surfaces as a result of the arcing event; updating estimates of cumulative erosion for the arcing surfaces; comparing the updated estimates of cumulative erosion to a first threshold value; and signaling for action when at least one of the updated estimates of cumulative erosion exceeds the first threshold value. | 03-05-2009 |

| 20090285624 | APPARATUS FOR PREVENTING INCORRECT INSTALLATION OF MACHINERY COMPONENTS TOGETHER - Apparatus for preventing incorrect installation of machinery components together includes a tab, pin and pin-receiving hole. The tab on the seal plate protrudes angularly from its periphery and laterally beyond it so as to prevent incorrect installation of two seal plates together in a faulty sealing relationship with machinery components by their tabs making interfering contact with one another producing a visible gap between the two seal plates. The pin is mounted on and protrudes axially from a surface of one machinery component facing the seal plate and prevents incorrect installation of the machinery components together in a faulty sealing relationship without the seal plate between them by the pin contacting the surface of the other machinery component and producing a gap between the machinery components. The hole extends through the seal plate to receive the pin within it when one seal plate is correctly installed between the machinery components. | 11-19-2009 |

| 20080252155 | SPRAY COOLED V-WEDGE FOR AEROSPACE GENERATOR - A high speed generator cooling system directs a cooling oil spray through a chamber inside a coil support wedge assembly, which may be disposed adjacent to the generator coils. Heat from the generator coils may be conducted through the walls of the coil support wedge assembly and into the chamber where it is removed by the cooling oil spray passing through the chamber. The cooling oil passes through a generator rotor shaft and into a cooling passage in least one of the rotor laminations. | 10-16-2008 |

| 20080234656 | METHOD FOR ALTERING DRUG PHARMACOKINETICS BASED ON MEDICAL DELIVERY PLATFORM - A method for directly delivering whereby a substance is introduced into an intradermal space within mammalian skin which involves administering the substance through at least one small gauge hollow needle having an outlet with an exposed height between 0 and 1 mm. The outlet is inserted into the skin to a depth of between 0.3 mm and 2 mm such that the delivery of the substance occurs at a depth between 0.3 mm and 2 mm. | 09-25-2008 |

| 20100077830 | ELECTRONIC SELF-CALIBRATION FOR SENSOR CLEARANCE - Self-calibration of a multiple channel clearance sensor system, which in one embodiment includes at least one sensor for measuring at least one clearance parameter signal between a stationary object and a rotating object of a rotating machine. The sensor output is processed as a clearance parameter by an offset correction section configured to determine an offset error in the clearance parameter signal which is used by a level shifter. The level shifter is also switchably coupled to the clearance parameter signal wherein the output of the level shifter, which may be amplified and digitally converted, is processed by a signal level analyzer to determine a channel gain signal. | 04-01-2010 |
| 20100188100 | AUTOMATED SENSOR SPECIFIC CALIBRATION THROUGH SENSOR PARAMETER DOWNLOAD - A sensor system for measuring a clearance parameter between a stationary component and a rotating component of a rotating machine is provided. The system includes a clearance sensor to output a clearance measurement signal. A sensor memory is attached to the sensor for storing a first sensor information. A second sensor information is stored in a electronics interface memory. The first and the second sensor information are read and the clearance sensor is matched with a respective plurality of calibration data by an electronic interface based on the first and the second sensor information. | 07-29-2010 |
| 20100191502 | SYSTEM AND METHOD FOR CLEARANCE ESTIMATION BETWEEN TWO OBJECTS - A processing system for clearance estimation in a rotating machine includes one or more sensors and one or more digital signal processors for calculating the estimated clearance. The processing system may include techniques for obtaining real-time clearance estimates and techniques for obtaining averaged clearance estimates. Aspects of the processing system may also include a method of switching between real-time clearance estimates and averaged clearance estimates depending on the operating conditions of the rotating machine. Other aspects of the processing system include the use of two digital signal processors: a first digital signal processor configured to receive signals from a clearance sensor and perform a first set of high speed processing tasks, and a second digital signal processor configured to receive signals from the first digital signal processor and perform a second set of lower speed processing tasks. | 07-29-2010 |

| 20090003991 | SYSTEM AND METHOD FOR TURBINE ENGINE CLEARANCE CONTROL WITH RUB DETECTION - A method of detecting rubs during operation of a turbomachine comprising at least one rotating object having a tip and a shelf is provided. The method includes generating signals representative of a sensed parameter and processing the signals to generate height versus time data for the tip. The height of the tip corresponds to the distance between the tip and the shelf. The method further includes monitoring the height versus time data, in order to determine whether a change in the height data exceeds a threshold value, and detecting a rub of the rotating object(s) on a second object, when the change in the height data exceeds the threshold value. A rub detection system for a turbomachine and a turbine engine system with rub detection are also provided. | 01-01-2009 |
