Abstract: The radio frequency front-end systems herein include modules having bandwidth controllable components, such as amplifier and filters. By implementing the modules with bandwidth control, the same module can be used for operation of multiple frequency bands including a first frequency band and a second frequency band. Thus, when implementing features such as carrier aggregation, multiple-input multiple-output (MIMO), and/or sounding resource signaling (SRS) for supporting the multiple frequency bands, the total number of modules used can be reduced and/or additional feature support can be provided compared to an implementation in which each module supports a single frequency band.

Abstract: An illustrative storage management appliance is interposed between client computing devices and one or more cloud storage resources. The appliance uses cloud storage resources in conjunction with a network attached storage device configured within the appliance to provide to the client computing devices seemingly unlimited network attached storage on respective network shares. The storage management appliance monitors data objects on the network shares and when a data object meets one or more criteria for archiving, the storage management appliance archives the data object to a cloud storage resource and replaces it with a stub and preview image on the network share. When access to the stub and/or preview image is detected, the storage management appliance restores the data object from the cloud storage resource. The criteria for archiving flexibly allow individual data objects to be archived to cloud storage without archiving frequently-accessed “neighboring” data objects on the same network share.

Abstract: A platform receives an input document from a user device and automatically determines a semantic signature for the input document based on a probabilistic distribution of rare words within the input document. The platform automatically scrapes at least one Internet database for additional documents and webpages, determining semantic signatures for each document or webpage. Based on similarity of semantic signatures, the platform automatically constructs and displays a graphical network of documents, wherein each document is represented as a node and similarity of semantic signatures is used to determine the locations of edges between nodes. The graph automatically groups nodes by communities and selects nodes in different communities to promote serendipity of results.
