Abstract: Embodiments of the invention provide methods and systems to analyze energy consumption and support demand management of a portfolio of facilities. Some embodiments of the invention include a computer implemented method for collecting and cleansing street addresses, time series energy consumption and weather data, classifying energy end-use types, detecting energy related characteristics, creating facility energy models, estimating energy savings potentials and generating customized recommendations for facilities. In some embodiments, the computer-implemented system and method also prioritizes a portfolio of facilities at each stage of the analysis based on facility data quality, level of confidence and energy savings potentials.

Abstract: Described are techniques for representing a data segment comprising. A list of one or more tokens representing one or more data portions included in the data segment is received. A unique identifier uniquely identifying said data segment from other data segments is received. A signature value determined in accordance with said list of tokens and said unique identifier is received. The list of tokens, said unique identifier, and said signature value are stored as information corresponding to said data segment.

Abstract: Described are techniques for performing restoration processing for a data segment. A list of tokens is received. The list represents a first data state of said data segment. Each of the tokens correspond to a data portion of said data segment. Data portions of the data segment are scanned. A token is determined for each data portion. The token represents the data currently stored in said data segment at said each data portion. For each data portion of said data segment, it is determined whether a first token from said list associated with said each data portion is different from a second token associated with said each data portion. The second token is determined as part of said scanning and corresponds to data currently stored at said each data portion. Each data portion of the data segment determined to have a first token that is different from a second token representing data currently stored at said each data portion is restored.

Abstract: A multimedia content system operates to manage mobile blogs created by users of communication devices. The mobile blogs may include content objects, which may be formed of audio components, text components, image, and/or video components. The various components may be formed from features of the communication devices. A user operating a mobile and/or non-mobile communication device may contact the system and provide one or more content objects for a mobile blog. The user may specify or create a community for accessing the mobile blog, and the multimedia content system publishes the blog for the community. Members of the community may view, edit, or augment the content objects of the mobile blog. Augmenting commands may be done through text messaging, email, or voice prompts. Users may access the mobile blogs through various communication devices. The content objects of the mobile blogs may be shared between users and indexed for easy retrieval.
