Abstract: An electric start system (20) includes a controller (40) that controls operation of a motor (22) used to start a device such as a gas turbine engine (24). In one example, the controller (40) determines when an acceleration rate of the motor (22) is outside of a desired range and dynamically controls the acceleration rate. In another example, the controller (40) determines when the motor (22) is disengaged from the engine (24) and controls a torque reference value to facilitate smoother reengagement. In another example, the controller (40) provides an initial starting torque value that allows for soft starting capabilities of the motor (22).

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.

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.

Abstract: A network for updating firmware, drivers, or application software facilitates the access to generated update packages by electronic devices and the update of firmware, drivers, content or application software in a fault tolerant mode. A “Bubbles” technique is employed to generate efficient and compact update packages. A “Bubbles” information is generated employing the “Bubbles” technique that is subsequently sent to the electronic devices as part of an update package. The “Bubbles” information and other related information is used in preprocessing activities and in other update related activities. For example, they are used to prepare the electronic device for an update to a different version of its firmware, software and/or content.

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.

Abstract: There are two different types of compression used on the Embedded Linux Platform that the present invention is targeting. For the kernel, a singular compression is used. A whole kernel is compressed into a single compressed zImage by zlib at once. When the kernel is loaded into RAM, the whole kernel has to be decompressed to RAM and executes there. The root file system is built through the CramFS that employs a different compression mechanism. It is a block-based compression. When the device is running, it is not necessary to load the whole file system to RAM. The kernel mounts the file system and performs the decompression on a file when it is needed.

Abstract translation: 在本发明所针对的嵌入式Linux平台上使用两种不同类型的压缩。 对于内核，使用单一压缩。 一个整个内核被zlib压缩成一个压缩的zImage。 当内核加载到RAM中时，整个内核必须被解压缩到RAM并在那里执行。 根文件系统是通过采用不同压缩机制的CramFS构建的。 它是一个基于块的压缩。 当设备运行时，不需要将整个文件系统加载到RAM中。 内核安装文件系统，并在需要时对文件执行解压缩。

Abstract: Disclosed herein is an electronic device network including a plurality of electronic devices. The electronic devices may each have updating software adapted to update firmware/software resident in the electronic devices. The electronic devices may also employ additional software for updating the updating software in the electronic devices. The electronic devices may also have software adapted to determine whether a current version of the updating software is to be invoked or whether a previous backup version of the updating software is to be invoked. The determination may be made based upon status information resident in a update status indicator. The status information may indicate that an update upon the updating software is to be conducted, rather than a normal startup operation without performing any updates. The network may also include an update generator adapted to generate updates for use in updating the updating software in the electronic devices.
