Abstract: According to one embodiment, in response to an inquiry received from a first application for an extension service associated with a first of a plurality of extension points of an operating system, a list of one or more extensions is identified that have been registered for the first extension point with the operating system, where the first application is executed within a first sandboxed environment. The identified list of extensions is displayed to prompt a user to select one of the extensions to be associated with the first application. In response to a selection of one of the extensions, the selected extension is launched in a second sandboxed environment. The selected extension and the second application were packaged in an application bundle, and when the application bundle was installed, the selected extension and the second application appeared in a registry of the operating system as separate applications.

Abstract: The present disclosure provides an extrapolation method of low rotational speed characteristics of a compressor, which is suitable for acquisition the low rotational speed characteristics of a gas turbine on the ground or an aircraft engine, the extrapolation method takes into account an application condition of a similarity principle and specialties of the low rotational speed operation condition of the compressor, and comprises modifying exponents of the similarity principle to obtain the optimal exponents by an optimization algorithm, and applying a coefficient fitting method for a variable operating condition calculation of the gas turbine to the extrapolation of low rotational speed characteristic of the compressor to obtain the low rotational speed characteristic.

Abstract: A host application executing on a client device includes a content processing extension that extends its functionality to process content items to a requesting host application executing on a client device. The content processing extension is an executable file that includes data conversion code and application code. The data conversion code, when executed in requesting host application, identifies content items provided by the requesting host application and formats the identified content items to be received by the content processing extension. The application code is native code executable by the host application associated with the content processing extension. The application code processes the results from execution of the data conversion and the identified content items in accordance with one or more functions of the host application, and returns the processed content items to the requesting host application via the content processing extension.

Abstract: A method, an apparatus and a system for eliminating aliasing noise in a multi-carrier modulation system are disclosed. The method includes: acquiring a first power spectrum density template; acquiring information of in-band subcarriers whose aliasing noise is greater than background noise, and acquiring a difference between the aliasing noise and the background noise of the in-band subcarriers; adjusting the first power spectrum density template according to the information of the in-band subcarriers and the corresponding difference to obtain a second power spectrum density template; and sending signals according to the second power spectrum density template. The method, the apparatus, and the system disclosed herein eliminate the aliasing crosstalk noise, improve the performance and stability of in-band services without involving upgrade or modification of the Customer Premises Equipment (CPE), and are easy to implement.

Abstract: Devices, systems, methods, and other embodiments associated with spare gates are described. In one embodiment, a spare gate in an integrated circuit has a disconnected discharge path to minimize or eliminate current leakage.

Abstract: A protection method in a packet transport network is provided. A protection path is established for a service data flow borne on a shared protection ring in the method, where the protection path includes a wrapping protection path and a steering protection path. Firstly, a first service data flow is sent through the wrapping protection path. Then, a service data flow node stops sending a second service data flow subsequent to the first service data flow to the wrapping protection path, and buffers the second service data flow. When the first service data flow completely passes by the service data flow node again, the buffered second service data flow is switched from the wrapping protection path to the steering protection path.
