  • Patent number: 11625785
    Abstract: An electronic tokening system implemented by a data source transmits secure electronic tokens including time-based values to a plurality of terminals. The terminals may be geographically disparate, and the different terminals may have different connection speeds to the data source. The terminals may use the secure electronic tokens to consistently and reliable calculate data values.

  • Publication number: 20220044210
    Abstract: PROBLEM TO BE SOLVED: To provide an information service system and the like that can notify useful information using location information to a user terminal that does not use a location-based service. SOLUTION: In a settlement server 200 in an information service system, an acquirer 242 acquires location information indicating a payment location where a payment was made, for example, when a taxi fare was paid by a payment application executed on a user terminal, from a settlement device that processes settlements in the taxi. A generator 243 generates regional information to be provided by an information service application of the user terminal, based on the acquired location information. Then, the transmitter 220 transmits the generated regional information to the user terminal, for example, in a push notification format.

  • Patent number: 11166460
    Abstract: The present invention relates to a microbicidal ?-amino acrylic derivative and its preparation method and applications. Based on the principle of pesticide molecular design, the structural reform of the agricultural anti-plant virus activity is carried on lead compounds having the medical anti-coronavirus activity, and a series of ?-amino acrylic derivatives are designed and synthesized, and in particular, ?-amino acrylic derivatives containing piperidine rings are synthesized, and the systematic biological activity screening is carried by using known compounds as positive control compounds, which provide many effective anti-virus leading molecules for the preparation of pesticides, and has positive significance to reduce the pesticide application dosage and protect the environment and ecology.
