Filed:

Jun 21, 2004

Appl. No.:

10/872625

Inventors:

James R. Gustafson - Granby MA, US
Kenneth Marks - Southwick MA, US
Douglas A. Parsons - Canton CT, US
Gregory I. Rozman - Rockford IL, US

Assignee:

Hamilton Sundstrand - Windsor Locks CT

International Classification:

G01M 15/00

US Classification:

73116, 731172, 731173, 731181

Abstract:

A turbine engine inspection arrangement utilizes a motor that is otherwise utilized for starting the engine. An inspection interface allows for communicating with a motor controller to operate the motor in an inspection mode. During inspection, the motor moves the components of the engine very slowly or in an incremental fashion to facilitate visual inspection of the engine components, such as the turbine blades.

International Classification:

US Classification:

340648, 340679, 318434, 318565, 361 23

Abstract:

A method and system for monitoring the performance of a permanent magnet device, such as a motor or generator, and providing early detection of motor performance deterioration. The back electromotive force (EMF) of the motor is measured at selected conditions when the motor is in a normal healthy condition to obtain a reference signature response. A measured signature is then obtained periodically during the life of the motor at the same conditions as the reference signature to check the current back EMF characteristic of the motor. If the measured signature deviates from the reference signature by a predetermined threshold, it indicates that the motor performance has degraded to a condition requiring attention.

International Classification:

H02P 7/00

US Classification:

318432, 318434

Abstract:

An electric start system () includes a controller () that controls operation of a motor () used to start a device such as a gas turbine engine (). In one example, the controller () determines when an acceleration rate of the motor () is outside of a desired range and dynamically controls the acceleration rate. In another example, the controller () determines when the motor () is disengaged from the engine () and controls a torque reference value to facilitate smoother reengagement. In another example, the controller () provides an initial starting torque value that allows for soft starting capabilities of the motor ().

International Classification:

K02K 9/00

US Classification:

310 52, 310 87

Abstract:

An electric motor has at least one component that is submerged in a cooling fluid held in a fluid-filled cavity. The stator, rotor, and rotor shaft bearings are all possible components that may be submerged. The cooling fluid floods the stator, rotor, and/or bearings to cool the components. The fluid may have a high electrical resistance to isolate the motor components from any contact with flammable gasses as well as prevent arcs or sparks. The cavity holding the fluid also ensures continuous lubrication by preventing fluid from leaking or evaporating out of the motor.

US Classification:

717172, 717173, 709202

Abstract:

Disclosed herein is a mobile services network including an electronic device with an update agent that may be capable of updating firmware and application software stored in non-volatile memory and employing multiple FLASH memory chips. The update agent may employ an update package generated to update firmware/software data segments and code segments. In an embodiment according to the present invention, the update agent may also employ a flash library supporting multiple FLASH memory chips from the same or different manufacturers. In an embodiment according to the present invention, the FLASH memory chips may be grouped. The update agent may also be capable of updating code in the multiple FLASH memory chips in the non-volatile memory of the electronic device.

US Classification:

717168, 714 5, 714 6, 711 5, 711 6

Abstract:

A mobile handset with a fault tolerant update agent employs an efficient interruption point detection technique to recover from interruptions during the update of firmware or software. In one embodiment, the update agent updates firmware and/or software employing a plurality of transforms, each transform employing one pass or a subset of one pass to execute, each pass associated with its own bank order and with its own decision maker bank (for recovery following a fault, such as power failure). The devices and method disclosed are applicable to other electronic devices such as, for example, personal digital assistants (PDAs), personal computers (PCs), pagers, and the like.

US Classification:

717168, 717174, 714 2

Abstract:

A mobile handset in a mobile services network, with access to a plurality of services including a firmware/software update service, is also capable of updating its update agent using an appropriate update package. The update package is retrieved from an update package repository via a management server. In one embodiment, the existing update agent is copied to a backup section before the update agent itself is updated. On the subsequent reboot, the new update agent is employed unless it is determined that it is corrupted or ineffective, in which case the old update agent is reactivated.

Inventors:

James Gustafson - Granby MA, US

International Classification:

F02C007/275

US Classification:

060/788000

Abstract:

A gas turbine engine system includes an electric starter motor which utilizes a partially hollow or cupped shaped rotor. Space is provided inside the rotor to fit the required clutch, bearings, and drive shaft. A short package is provided due to the telescoped architecture while retaining the maximum length for electromagnetics.
