Abstract: An operation state determination system includes a receiver, a first memory and a determiner. The determiner is configured to compare, at a prescribed determination time point, a power value stored in the first memory with a reference value to determine whether or not an electric load connected to a branch circuit is in operation, and output a signal in accordance with a determination result. The determiner is further configured to determine that the electric load is in operation at the prescribed determination time point, when a time period during which the power value is equal to or more than the reference value occurs within a comparison time in past before the prescribed determination time point.

Abstract: A dementia determination device in a dementia information output system includes an obtainer which obtains, on a per unit period basis, the result of measuring body motion of a user in a sleep time period; and an outputter which outputs dementia information indicating the likelihood that the user is developing a mild cognitive disorder based on the occurrence frequency of a unit period in which the magnitude of a difference between reference data on body motion of a healthy subject in a sleep time period and the result of measuring obtained by the obtainer exceeds a predetermined threshold value.

Abstract: Cognitive decline detection system includes obtainment unit and determination unit. Obtainment unit obtains the amount of movement during a sleep period and the amount of movement during a non-sleep period of a user for each day, the non-sleep period being the period other than the sleep period. Determination unit determines that the cognitive function of the user is lower during a determination period than during a comparison period set before the determination period when the frequency of days when a movement amount ratio falls below a predetermined ratio among days constituting the determination period is higher than that among days constituting the comparison period, the movement amount ratio representing the ratio of the amount of movement during the non- sleep period to the amount of movement during the sleep period.

Abstract: A cognitive function evaluation device includes an acquirer that acquires speech data that indicates speech uttered by an evaluatee in response to a task given to the evaluatee; an evaluator that evaluates a cognitive function of the evaluatee by performing a first evaluation based on a proportion of speaking time of the evaluatee in a predetermined period in the speech data acquired by the acquirer and a second evaluation based on a fundamental frequency in the speech data acquired by the acquirer; and an outputter that outputs an evaluation result obtained from the evaluation performed by the evaluator.
