  • Patent number: 12578298
    Abstract: A carbon monoxide gas sensor is a single-chamber sensor for measuring the carbon monoxide gas concentration in a gas phase. The carbon monoxide gas sensor has electrodes disposed on respective sides of a solid electrolyte layer. One of the electrodes is active for oxidation of carbon monoxide gas, and the other of the electrodes is more inactive for oxidation of carbon monoxide gas than the one electrode. The carbon monoxide gas sensor is configured to measure a short-circuit current between the electrodes. In the carbon monoxide gas sensor, the solid electrolyte layer has oxide ion conductivity.

  • Patent number: 12518458
    Abstract: A first video generator generates first information for displaying, as a first video, a character object of a first user and a first object. A second video generator displays the first object and a third object different from the second object. An association portion associates the character object of the first user with a fourth object associated with the third object when the character object of the first user and the third object have a predetermined relationship. The second video generator displays the fourth object in association with the character object of the first user when the fourth object is associated with the character object of the first user by the association portion.
