  • Publication number: 20220140369
    Abstract: A fuel cell system includes: an upstream side flow path forming a flow path from an oxidation gas supply apparatus toward a fuel cell; and a downstream side flow path forming a flow path from the fuel cell toward an atmosphere. The fuel cell system includes: an oxidation gas pressure sensor that measures a pressure inside the upstream side flow path; and a controller that can execute a water content estimation mode of estimating a water content in an oxidation gas flow path including the fuel cell. The controller includes: a water content calculation unit that calculates the water content in the oxidation gas flow path including the fuel cell on a basis of an oxidation gas flow rate and an oxidation gas pressure loss.

  • Patent number: 11080313
    Abstract: A computer-implemented method, computer program product, and system are provided for providing a recommendation. The method includes receiving, by a conversation system, a query from a user. The method also includes inputting the query into an intent-entity model to obtain a first output. The method further includes inputting the query into a question-answering system to obtain a second output. The method additionally includes analyzing the first output from the intent-entity model to calculate a value of degree of ambiguity of the first output to the query. The method also includes analyzing the query and the second output from the question-answering system to calculate a value of extent of satisfaction to which the second output satisfies the query. The method further includes determining one or more recommendations using the degree of ambiguity and the extent of satisfaction. The method additionally includes outputting the one or more recommendations to the user.

  • Patent number: 10464211
    Abstract: A computer-implemented method for generating a control signal for a tele-presence robot by a computing device based on a movement of an operator, the method includes calculating a direction where at least part of the operator is positioned based on a camera acquiring an image of the at least part of the operator; calculating an orientation where the at least part of the operator points; and generating at least one motion parameters of the tele-presence robot as the control signal based on the direction in combination with the orientation, wherein the direction and the orientation are reflected to the at least one motion parameters differently.

  • Patent number: 8707695
    Abstract: A heat engine includes a container in which a liquid piston made of a liquid operation fluid is sealed to flow therein, an exterior evaporator located outside of the container to generate vapor of the operation fluid, a suction portion arranged at one end side of the container to draw the vapor generated in the exterior evaporator into the container, an expansion portion in which the vapor drawn into the container is expanded to cause a displacement of the liquid piston, an output portion arranged at the other end side of the container to convert the displacement of the liquid piston to a mechanical energy, a liquid piston discharge portion for discharging a part of the liquid operation fluid as the liquid piston from the container, and a vapor discharge portion configured to discharge the vapor without being condensed in the container to outside of the container.

  • Publication number: 20110308774
    Abstract: An apparatus of a heat transfer circuit in which a heat transfer fluid with small particles circulates includes a container and an agitator. The container is located in a lower position of the apparatus in a vertical direction and defines a chamber where the heat transfer liquid passes when circulating in the heat transfer circuit. The agitator is located in the chamber to agitate the heat transfer fluid.

  • Patent number: 7685260
    Abstract: A method that enables a tester to efficiently perform confirmation behavior of a Web page that utilizes DHTML or difference in behavior of the Web page among various browsers, or assignment of information relating to accessibility of the Web page or verification of the information. A method is provided that analyzes change in a Web page by determining states that can dynamically occur in response to an external event in a Web page that utilizes DHTML by analyzing at least one of DOM, style information for when rendered on a browser, input data from a user, and the value of a global variable in JAVA®SCRIPT, storing data that can identify each of the states, identifying state transition between the stored states, and reproducing the stored states.
