Abstract: A refrigeration cycle apparatus includes a refrigeration cycle circuit, a bypass flow path, a first valve provided in the refrigeration cycle circuit, a second valve provided at the bypass flow path, a first temperature sensor configured to detect a temperature of an indoor space, a second temperature sensor configured to detect a temperature of refrigerant on a liquid side of an indoor heat exchanger, and a notification part. The refrigeration cycle apparatus is able to operate in an operation state where the compressor operates, the indoor heat exchanger functions as an evaporator, and the first valve is open while the second valve is closed. In the operation state, the notification part issues notification of an abnormality of an electronic expansion valve or the first valve when a temperature detected by the second temperature sensor is higher than an evaporation temperature of refrigerant in the refrigeration cycle circuit.

Abstract: Provided is a server device that acquires user attribute information indicating an attribute of a user boarding on a mobility that travels from a departure place to a destination in response to an instruction of the user, acquires location information indicating a location of the mobility during traveling, and generates a database in which a predetermined place existing between the departure place and the destination of the mobility, the predetermined place being specified based on the location information, is associated with the user attribute information.

Abstract: An acquisition unit acquires, regarding a battery that is a determination target, first data indicating a charge-discharge history in a first period and second data indicating a charge-discharge history in a second period before the first period, a calculation unit calculates a first state quantity indicating a state quantity of the battery in the first period based on the first data, and calculates a second state quantity indicating an estimated value of the state quantity of the battery in the first period based on the second data, a determination unit performs authenticity determination as to whether the battery is a genuine product or an imitation product in the first period based on the first state quantity and the second state quantity, and an output unit outputs a result of the authenticity determination.

Abstract: A server acquires, from a terminal owned by a user, pairing information in which a user ID for identifying the user and a mobility ID for identifying a mobility used by the user are associated with each other; continuously acquires, from the terminal, terminal position information indicating a position of the terminal and associated with the user ID; specifies a user ID of a user using the mobility that is stopped, based on the pairing information; and determines, as position information of the mobility, the terminal position information associated with the user ID having been specified.

Abstract: A server device acquires location information indicating a location of a mobility, identification information on another mobility, the identification information being received from the other mobility by near field communication, and stop information indicating whether the mobility stops, from multiple mobilities; classifies two or more mobilities into a same mobility group, the two or more mobilities stopping and mutually receiving the identification information among the multiple mobilities; and specifies a stop place where the mobility group stops based on the location information on the two or more mobilities classified into the mobility group.

Abstract: A refrigeration cycle apparatus includes a refrigeration cycle circuit that has a compressor, a condenser, an expansion device, and an evaporator that are connected through a pipe, the refrigeration cycle circuit being configured to allow refrigerant to circulate in the refrigeration cycle circuit, and a controller configured to determine whether the refrigerant leaks or whether the expansion device malfunctions on the basis of a degree of subcooling at an outlet of the condenser and a degree of superheat at an outlet of the evaporator or a degree of superheat at a suction port of the compressor.

Abstract: The air-conditioning system control apparatus includes an influence-degree calculation unit that calculates a degree of influence between two air-conditioning indoor units that are selected from a plurality of air-conditioning indoor units as a pair of air-conditioning indoor units, based on operation data on the pair of air-conditioning indoor units.
