Abstract: A system, apparatus, and method are disclosed to provide an enhanced search index for searchable content by limited capability devices, such as mobile phones. A URL analyzer determines clusters of mobile web page URLs and corresponding tokens. A landing page identifier evaluates cluster URLs and the tokens to identify landing page URLs for mobile web pages likely to be relevant to an associated search term. A mapper associates the landing page URLs with related domain hosts that include conventional web pages generally not accessible to limited capability devices. A category tagger associates the landing page URLs with categories of conventional web pages that share a content topic. The landing page URLs, and corresponding tokens, domain host information, and categories are added to the search index. A submitted search term is evaluated relative to the tokens, domain host information, and categories to determine relevant mobile web landing pages as search results.

Abstract: In one aspect there is provided a method. The method may include receiving a first analog radio frequency signal including a signal of interest and an interference signal caused by a second analog radio frequency signal transmitted in full duplex over a channel from which the first analog transmission is received; combining the first analog radio frequency signal and a portion of the second analog radio frequency signal to generate an output analog radio frequency signal characterized by at least a reduction or an elimination of the interference signal included in the output analog radio frequency signal; and providing the output analog radio frequency signal. Related apparatus, systems, methods, and articles are also described.

Abstract: A system, apparatus, and method are disclosed for providing a single source for searchable content by mobile devices. Mobile user agents crawl host sites to determine whether there is content that may be viewed by any of the mobile user agents. If files are identified as viewable for a given mobile user agent, the site is tagged as crawlable. A best mobile user agent may also be identified for that site, based on number of files viewable, response time, file mobileness, or the like. The sites may be discovered by instrumentation of URLs with mobile device keywords, performing a backlink analysis to discover interlinking of mobile device related sites, exploring URLs of a known host name for potential starting points for mobile device sites, or employing a list of known popular conventional sites with a mobile user agent for possible redirections to a potential mobile device web site.

Abstract: A system, apparatus, and method are disclosed to identify and tag documents that are mobile documents in that they are compatible with limited capability devices, such as mobile phones. A website hosting a document is checked to determine whether the website considers the document to be a mobile document. The document is also for indications that the document is a mobile document. The indications include a content type, a document type, and/or markup tags that are consistent with a mobile document. A URL for the document is also checked for parameters indicating a mobile document. The above information is used to determine one or more categories of mobile devices that could display or otherwise process the document. A confidence level is determined indicating a degree of confidence that the document is a mobile document. The information is used for searching documents for those that are likely to be mobile documents.
