  • Patent number: 11938936
    Abstract: In a stand-up vehicle having a vehicle upper part having a riding surface configured for a user to stand on, one or more electronic control units execute emergency situation detection processing for detecting an emergency of the user when receiving notification from the user or based on information from one or more sensors, safety posture determination processing for determining whether or not the user takes a safety posture based on information from one or more sensors after detecting the emergency, and upper limit speed management processing executed when detecting the emergency and determining that the user takes the safety posture. The upper limit speed management process increases the upper limit speed to be higher than the basic upper limit speed selected when the safety posture determination process determines that the user is not in the safety posture, or cancels the upper limit speed.

  • Publication number: 20070132549
    Abstract: A manufacturer of an article generates a keyword, and electromagnetically writes the keyword into an RFID and prints the keyword on a guarantee card. The RFID tag is then affixed to the article, and the article is packed along with the guarantee card and shipped. When making a sale, a retail store hands over the guarantee card to a customer who buys the article. When the customer wishes to sell the article, a purchasing store reads the keyword written to the RFID tag affixed to the article and asks the customer to furnish the keyword. If the keyword furnished by the customer, by referring to the guarantee card, etc., is identical to the keyword read from the RFID tag, the customer is deemed a genuine owner of the article.
