  • Publication number: 20180373738
    Abstract: An information presentation apparatus obtains monitoring information that indicates a state of a monitoring target, accumulates it in a storage unit, and detects, based on the monitoring information accumulated in the storage unit, the occurrence of an information presentation trigger event. The information presentation apparatus generates, based on the monitoring information accumulated in the storage unit, search data for searching for relevant information related to the detected event, uses the generated the search data to search for the relevant information, and generates presentation information for present the relevant information found by the searching.

  • Patent number: 7514179
    Abstract: A valve-regulated lead-acid battery of this invention includes: an electrode plate group; and an electrolyte impregnated into and retained by the electrode plate group. The electrode plate group includes: positive electrode plates that each include a positive electrode current collector comprising a Sn-containing lead alloy, and a positive electrode active material retained by the positive electrode current collector; negative electrode plates that each include a negative electrode current collector comprising a lead alloy, and a negative electrode active material retained by the negative electrode current collector; and separators. The Sn content in the positive electrode current collector is 1.1 to 3.0% by mass, and the pore volume per unit mass of the negative electrode active material is 0.115 to 0.150 cm3/g.
