  • Patent number: 10992988
    Abstract: The present application disclose a method, system, and an intelligent terminal for distributing random data. The method comprises the following steps: obtaining a user instruction to be executed; generating data to be shared based on the user instruction, wherein the data to be shared is conditioned on a delay; detecting whether an ended condition of the delay is fulfilled; and receiving a first request for accessing the data to be shared in response to that the ended condition is fulfilled.

  • Publication number: 20200340415
    Abstract: The control device for an internal combustion engine disclosed in the present application is a control device that determines the presence or absence of misfire based on an angle detection cycle calculated from an output signal of an angle sensor, the control device includes an arithmetic processing device and a storage device, the control device is configured so that the storage device stores the angle detection cycle calculated in a misfire detection threshold value comparison section after the reference angle section as a threshold value comparison target cycle and is configured such that the arithmetic processing device determines the presence or absence of misfire based on the misfire detection threshold value cycle calculated based on the reference detection cycle and the threshold value comparison target cycle, thereby it becomes possible to accurately determine the presence or absence of misfire in the control device for the internal combustion engine.

  • Publication number: 20200316505
    Abstract: The present invention provides A magnesium oxide whisker in-situ formed MA spinel-reinforced magnesium oxide-based ceramic foam filter and a method for preparing the same. The method comprising: 1) preparing a ceramic slurry having a solid content of 60%-70% by dosing 15%-25% by mass of a nanometer alumina sol, 0.8%-1.5% by mass of a rheological agent, and the balance magnesium oxide ceramic powder comprising magnesium oxide whiskers, and then adding deionized water and ball milling to mix until uniform, and then vacuum degassing the mixture; 2) soaking a polyurethane foam template into the ceramic slurry, squeezing by a roller press the polyurethane foam template to remove redundant slurry therein to make a biscuit, and drying the biscuit by heating it to 80° C.-1200° C.; 3) putting the dried biscuit into a sintering furnace, elevating the temperature to 1400° C.-1600° C.

  • Publication number: 20060159241
    Abstract: A framework is described for providing a service to a customer via a Interactive Voice Recognition system (IVR) using natural language expressions. The expressions are evaluated using rules-based programming rules. Evaluated expressions determine an eligibility of a business service to be offered to a customer. Interaction with the customer comprises selecting a semantically correct natural language expression from an appropriate vocabulary database.
