  • Patent number: 10263753
    Abstract: In order to improve the quality of communication between electronic devices, one or more sub-channels used during communication between the electronic devices are dynamically modified based on one or more performance metrics and allowed transmit powers of the sub-channels. In particular, when the one or more performance metrics indicate that a distance between the electronic devices falls within a mid-range of distances, the one or more performance metrics may be used to guide selective changes to the sub-channels used during the communication based on the allowed transmit powers. The changes to the sub-channels used during the communication may increase, decrease or leave the total bandwidth unchanged. Moreover, by changing the sub-channels used during the communication, the allowed transmit power(s) of the sub-channel(s) used may be increased, which may improve the performance during the communication.

  • Publication number: 20190095286
    Abstract: A system and method are presented that identify new, modified, unchanged, and deleted files in an incremental backup through a file list maintained on the backup destination. The FileList is a flat file in which file information about each file on a source node is stored sequentially into the file. During a subsequent incremental backup, the FileList is read sequentially from the backup destination and is used to generate a search tree. A hash value based on the file path is the key to the search tree, with the file's modified time and size being hashed together to form the value of the tree's key-value pair. Files are examined on the source and compared to the key-value pairs in the search tree. Status information in the search tree is modified to indicate discovered files. Unmodified status information identifies files that have been deleted since the previous backup.
