  • Publication number: 20220210877
    Abstract: A microwave treatment device comprises: a heating chamber that accommodates an object to be heated; a microwave generator that generates a microwave in a specified frequency band; an amplifier that amplifies the microwave; a feeding unit that supplies the amplified microwave to the heating chamber; a detector that detects a reflected microwave power; and a controller. The controller selects one of plural frequencies in the specified frequency band and causes the microwave generator to generate the microwave with the selected frequency. The controller causes the amplifier to change an output power of the microwave so that the microwave supplied to the heating chamber has one of plural output powers. The controller measures a reflected microwave frequency characteristic based on reflected microwave powers detected under each of a condition that the microwave has a first output power and a condition that the microwave has a second output power.

  • Patent number: 11373533
    Abstract: A vehicle control apparatus acquires a position of an other vehicle that is present ahead of the own vehicle in its traveling direction, and uses the acquired position of the other vehicle to calculate a movement locus, which is a past path of the other vehicle. The vehicle control device calculates a lateral movement amount of the movement locus in a predetermined range in the traveling direction of the own vehicle, the lateral movement amount being an amount of change in position in a lateral direction which is a direction intersecting the traveling direction, and calculates an average value of the lateral movement amounts. The vehicle control apparatus excludes, from the movement loci, a movement locus having a lateral movement amount whose difference from the average value is larger than a predetermined value, and calculates the predicted path based on remaining movement loci.

  • Publication number: 20220135032
    Abstract: A vehicle control device executes a cruise control to let a vehicle travel in such a manner that an acceleration is equal to a predetermined acceleration, when an execution condition becomes satisfied, and starts a vehicle speed upper limit control to let the vehicle travel in such a manner that the vehicle speed does not exceed an upper limit value determined based on a shape of a curve section, when a start condition becomes satisfied. The vehicle control device starts displaying a display element in a first display mode, when the vehicle speed upper limit control is started. At a time point at which the vehicle speed upper limit control is ended, the vehicle control device starts displaying the display element in a second display mode different from the first display mode if the execution condition is not satisfied.
