    • A virtual path provider allows a Web application to access content source that is maintained by a file system, and/or content source that is maintained separately from a file system. When the Web application receives a request for processed content from a requesting computer system, the Web application access the processed content in cache if there is a valid cache entry, or accesses the corresponding content source through a virtual path provider. If appropriate for the content source, the virtual path provider streams the content source to the Web application through a virtual path. In one implementation, the virtual path provider provides a hash value of the content source, which can be compared to a cache entry. Implementations of the present invention, therefore, allow content source from any virtual store at any location to be processed or compiled by a Web application.
    • 虚拟路径提供程序允许Web应用程序访问由文件系统维护的内容源和/或与文件系统分开维护的内容源。 当Web应用从请求的计算机系统接收到处理的内容的请求时,如果存在有效的高速缓存条目,则Web应用访问处理的内容,或通过虚拟路径提供者访问相应的内容源。 如果适用于内容源,则虚拟路径提供者通过虚拟路径将内容源流式传输到Web应用程序。 在一个实现中,虚拟路径提供者提供内容源的哈希值,其可与高速缓存条目进行比较。 因此,本发明的实现允许来自任何位置的任何虚拟存储的内容源被Web应用程序处理或编译。

    • Embodiments of the invention provide systems and methods for tracking the thermal age of a self-regulating heating cable. Over a time period, current and voltage data for a cable signal are collected, from which spectral information is extracted. The spectral information has a frequency component and an amplitude component. The cable signal is processed to extract a line frequency signature that includes the electrical system's line current frequency and at least some of its harmonics. A ratio of the amplitudes of at least two of the odd harmonics of the line current frequency is calculated. The ratio is compared to an aging curve indicating the thermal age of the cable as a function of the odd-harmonic ratios. The curve may be obtained in a laboratory setting or in the field by characterizing a cable with zero hours of use. The characterizing may include aging the cable to determine the curve.
    • 本发明的实施例提供了用于跟踪自调节加热电缆的热寿命的系统和方法。 在一段时间内,收集电缆信号的电流和电压数据,从中提取光谱信息。 频谱信息具有频率分量和振幅分量。 处理电缆信号以提取包括电气系统的线路电流频率和其至少一些谐波的线路频率特征。 计算线路电流频率的至少两个奇次谐波的振幅比。 将该比率与表示电缆的热寿命作为奇次谐波比的函数的老化曲线进行比较。 曲线可以在实验室设置中或在现场通过使用零小时的电缆进行表征来获得。 特征可能包括老化电缆以确定曲线。
