Abstract: A scent-presentation-information output system includes a scent-provision-information storage unit, a scent-provision-information acquisition unit, a clustering unit, a scent-presentation-information generation unit, and a scent-presentation-information output unit. The scent-provision-information storage unit stores, as scent provision information, scent identification information useable to identify a scent provided to a user, scent evaluation information indicating an evaluation of the scent by the user, and user identification information useable to identify the user in association with one another. The scent-provision-information acquisition unit acquires the scent provision information. The clustering unit classifies, based on the scent provision information, the user into a predetermined cluster. The scent-presentation-information generation unit generates, based on pieces of scent provision information of all or other users who belong to the cluster, scent presentation information useable to present a scent recommended to the user. The scent-presentation-information output unit outputs the scent presentation information in a form suitable for use by an output destination.

Abstract: An environment-control-means control apparatus controls an environment of a target space using a plurality of environment control means. The control apparatus includes a grasping unit and a control unit. The grasping unit may grasp state information relating to states of a plurality of subject persons. In this case, the control unit controls a plurality of kinds of environment control means such that the state information of the plurality of subject persons grasped by the state information grasping unit satisfies a predetermined target state condition. The grasping unit may grasp a second environmental stimulus given to a subject person other than a first environmental stimulus caused by control of the environment control means. In this case, the control unit controls the environment control means such that an influence of the second environmental stimulus grasped by the environmental stimulus grasping unit on the subject person is cancelled or reduced.

Abstract: A setting facilitation apparatus (1400) includes a keyword input reception section (1410), a control command selection section (1420), and a specific control registration section (1430) and is used to facilitate setting of specific control in a control system (1001) that controls a control device through sound inputs. The keyword input reception section (1410) receives an input of information corresponding to a keyword. The control command selection section (1420) displays a certain control command to the control device (1010, 1020) on an edit screen (G) and receives selection of the control command. The specific control registration section (1430) registers a keyword (K) input by the keyword input reception section (1410) and the control command selected by the control command selection section (1420) to a specific control (DB 1104T) while associating the keyword and the control command with each other.

Abstract: [Object] On the basis of a limit of an operation of a control unit that is connected to a power-receiving path of a converting unit, is electrically parallel with the converting unit, and controls apparent power in the power-receiving path of the converting unit, the operation of the control unit is controlled.
[Solution] A power control system includes: an acquisition section that acquires control unit information related to a limit of an operation by a control unit provided for a heat pump system that regulates temperature and/or humidity; and a control section that controls an operation of the control unit on the basis of the control unit information. The control unit is connected to a power-receiving path of a converting unit that converts received power and supplies the converted power to a load used for the regulating. The control unit is electrically parallel with the converting unit. The control unit controls apparent power in the power-receiving path.-

Abstract: [Problem] As compared with the case where the apparent power in the electric line on the supply side is adjusted without supplying the current to the electric line closer to the power supply side than the distribution transformer, there is a reduction in the effect of the state in the electric line closer to the power reception side than the distribution transformer on the adjustment of the apparent power in the electric line closer to the power supply side than the distribution transformer.
[Solution] A power control system includes a device that receives power from an electric line of a distribution system via a distribution transformer, an acquisition unit that acquires electric line information on the electric line, and a control unit that causes the device to generate a current used for adjustment of apparent power in the electric line based on the electric line information acquired by the acquisition unit.-

Abstract: An air conditioning control device includes a control unit, a skin temperature measurement unit, an information acquisition unit, and a determination unit. The control unit controls an air conditioner that performs air conditioning of a room where a user is present. The skin temperature measurement unit measures a skin temperature of the user. The information acquisition unit acquires thermal sensation information of the user regarding the space where the user is present. The determination unit determines a comfortable skin temperature range in which the user feels comfortable, based on a skin temperature of the user obtained at the time of acquiring of the thermal sensation information. The control unit controls the air conditioner based on the comfortable skin temperature range determined by the determination unit.
