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.

Virtual network interface selection manager in a client-server system, in which client and server are connectable through a plural alternate networks. System includes plural interfaces connectable to server through the plural networks, current interface indicator identifying a current interface through which data is transmitted to and/or received from the server, and prioritized listing of plural interfaces ranked in a descending order. Event detector detects occurrence of an event including time-out condition; successful interface test; and change in the plurality of interfaces, and a tester tests each plural interface in prioritized listing in a ranked order to test whether server is reachable. Marker identifies which of plural interfaces successfully pass the test, and switch switches from current interface to a higher priority interface when the marker identifies a higher priority interface as having successfully passed the test, whereby current interface indicator will identify the higher priority interface as current interface.

A composition is provided for removing protein soil and preventing redeposition of soils onto a surface. The composition includes between about 1% and about 90% by weight sugar, between about 1% and about 80% by weight alkalinity source and between about 15 and about 10% by weight surfactant composition. The sugar may be a saccharide or a non-saccharide based sugar. The composition is substantially free of phosphorus-containing compounds and includes less than about 0.05% by weight alkali earth metal.

The present invention extends to methods, systems, and computer program products for managing network response buffering behavior. A computer system receives a request for content from a client. The computer system has a default response buffering behavior used when transferring content. The computer system maps the request to a handler configured to serve the requested content. The computer system accesses buffering behavior data for the handler. The computer system determines that the requested content is to be transferred in accordance with altered response buffering behavior based at least on the buffering behavior data. The altered response buffering behavior corresponds to the requested content as an exception to the default response buffering. The computer system accesses a portion of the requested content from the handler. The computer system transfers the portion of requested content to the client in accordance with the altered response buffer behavior.

Caching data. A method may be practiced, for example, in a computing environment including a server system that provides data to client systems. The server system includes a number of caches for storing data. The method allows a least expensive cache to first cache data or return data requested by a client. The method includes receiving data to be cached at a cache. The method further includes determining that the data has not been previously cached at a preceding cache. If the data has not been previously cached at a preceding cache the data is cached at the cache. Alternatively, requests for data may be received at a first cache. If the data is at the first cache, the first cache returns the data. If the data is not at the first cache, the request for data is forwarded to a subsequent cache.

Methods are provided for utilizing a modular server architecture for processing requests for services, such as authorization and authentication, in a web server. The modular server architecture includes self-contained modular components that can be plugged in and out of the web server, as needed, to provide requested web services. The modular server architecture is also extensible in that it provides set of server APIs for processing requests for supporting built-in server functionality as well as functionality provided by third party modular components. The modular server architecture also supports the integration of request processing tasks for both native and managed modular components, such as ASP.NET modules, by virtue of a managed module host component. The modular server architecture also optimizes server performance by only providing modular component functionality when needed. By utilizing the modular server architecture, server functionality is extended, duplication of request processing tasks is eliminated and performance administrative overhead is reduced.

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.

An optical system configured to detect optical signals during imaging sessions. The optical system includes an objective lens that has a collecting end that is positioned proximate to a sample and configured to receive optical signals therefrom. The optical system also includes a removable path compensator that is configured to be located at an imaging position between the collecting end of the objective lens and the sample. The path compensator adjusts an optical path of the light emissions when in the imaging position. Also, the optical system includes a transfer device that is configured to move the path compensator. The transfer device locates the path compensator at the imaging position for a first imaging session and removes the path compensator from the imaging position for a second imaging session.

A method and composition is provided for removing protein soil and preventing redeposition of soils onto a surface. The method includes introducing a protein-removing/anti-redeposition agent during a washing step of a wash cycle, introducing a cleaning composition during the washing step of the wash cycle, washing the surface of the substrate with the protein-removing/anti-redeposition agent and the cleaning composition during the wash cycle, and subsequently rinsing the surface of the substrate with a rinse aid. The protein-removing/anti-redeposition agent includes a poly sugar and the cleaning composition includes an alkalinity source and a surfactant component. The composition is substantially free of phosphorus-containing compounds and includes less than about 0.05% by weight alkali earth metal.
