  • Code information reading device, method, and computer-readable storage medium
    Patent number: 11373053
    Abstract: A recognition section detects code information from each of plural frames included in video image data and recognizes the code information. A determination section determines that a recognition result recognized by the recognition section is valid in at least one scenario out of a scenario in which at least part of the recognition result matches a predetermined character, or a scenario in which a number of characters in the recognition result matches a predetermined number, or a scenario in which the same recognition result is recognized in two or more consecutive frames. An output section employs a recognition result determined to be valid by the determination section to output a reading result for the code information.

  • Zeolite converter for diesel engine
    Patent number: 5343702
    Abstract: An exhaust gas purifier for a diesel engine is positioned in the middle of an inlet system for supplying air to a combustion chamber. The exhaust gas purifier includes an HC (hydrocarbon) supply source, and a zeolite catalyst converter, which is activated by the hydrocarbon as a reduction agent to crack NOx (oxides of nitrogen) in the exhaust gas, for thereby purifying the exhaust gas.
