  • Arousal state estimation apparatus and arousal state estimation method
    Patent number: 11523760
    Abstract: An arousal state estimation apparatus includes: a feature value acquisition unit acquiring a plurality of types of feature values regarding an arousal state of a human body from physiological data obtained by measuring the human body; and an estimation unit estimating the arousal state of the human body by using a principal feature value that is some type among the plurality of types of feature values. In a case where the principal feature value is unacquirable due to a defect of the physiological data, the estimation unit estimates the arousal state of the human body by using a different type of feature value than the principal feature value among the plurality of types of feature values acquired by the feature value acquisition unit instead of the unacquirable principal feature value.

    Patent number: 5937391
    Abstract: A service system in an online shopping mall established through a network realizes an improvement of a service to a customer by not having to carry a magnetic card and shortening a time from issuing points to redeeming points. To attain the objects of the system, a points issuing unit issues points corresponding to the purchase amount of a customer. A points storage device stores the number of points accumulated by the customer. A points redeeming unit reduces a purchase amount of the customer as points to be redeemed. A points issue ratio and a points redeeming ratio can be set for each shop forming part of the online shopping mall.
