  • Patent number: 8892991
    Abstract: The reading unit reads mapping information that maps a particular point in a document structure defined by XML schema to the name of a variable and a training XML document that includes a substitute character string positioned at a particular point and tags. A parser converts the training XML document into a sequence of events each specifying one of substitute character string and the tag names. The reading unit reads in an EXI grammar form. A code composer processes the sequence of events and generates an EXI event code based on the EXI grammar form, generates a function to retrieve the value of a variable mapped to the particular point at which the substitute character string is positioned when the event is an event specifying substitute character string, and produces an EXI encoder including output instruction codes to output EXI event codes and the retrieved value of the function.

  • Patent number: 8880355
    Abstract: According to one embodiment, an emission factor calculating apparatus includes a receiving unit, a received electricity (i.e., electric power) measuring unit, a generated electricity measuring unit, and an emission factor calculating unit. The receiving unit receives an emission factor of a higher-level system at first regular intervals. The received electricity measuring unit measures, as a received electricity, electricity received from the higher-level system and accumulated. The generated electricity measuring unit measures electricity generated with zero emission in a target system. The emission factor calculating unit calculates a substantial emission factor of the target system at regular intervals (i.e., at a fixed interval), based on a ratio between the received electricity and the measured electricity generated, and the emission factor of the higher-level system. The emission factor calculating unit informs a load or a lower-level system of the substantial emission factor.
