Toshiharu SUGINO has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Leakage suppression apparatus, leakage suppression system, and leakage suppression program
    Patent number: 10095246
    Abstract: A pressure estimator, based on information acquired by an acquirer and model information that includes connection information of nodes in a water distribution pipeline network, estimates water pressure at at least one part of the nodes in the water distribution pipeline network. An extractor extracts a minimum water pressure value from a plurality of water pressures that include the water pressure estimated by the pressure estimator. A controller controls an adjustor to adjust at least one of a water pressure and a flow rate of water flowing into the water distribution pipeline network, based on a minimum water pressure value extracted by the extractor.

  • WATER LEAKAGE DIAGNOSIS DEVICE, WATER LEAKAGE DIAGNOSIS METHOD, AND NON-TRANSITORY COMPUTER READABLE STORAGE MEDIUM
    Publication number: 20180209124
    Abstract: A water leakage diagnosis device in an embodiment includes a total water leakage amount acquirer, a node water usage amount acquirer, a node water leakage amount estimator, an estimation parameter setting unit, and a water leakage location estimator. The total water leakage amount acquirer acquires a total water leakage amount in a pipe line network on the basis of an amount of water flowing into a pipe line network and an amount of water used by a customer in the pipe line network. The node water usage amount acquirer acquires a node water usage amount indicating a total amount of an amount of water to be used at each node in the pipe line network. The node water leakage amount estimator estimates the node water leakage amount a plurality of times on the basis of the total water leakage amount, the node water usage amount, and an estimation parameter.
