Abstract: Provided is an electric device made more convenient by being configured such that the temperature of a wide area in each accommodation section can be individually adjustable. In an electric device, a first refrigerant pipe is provided to a right-side member constituting a side surface of a first accommodation chamber, and a second refrigerant pipe is provided to a left-side member constituting a side surface of a second accommodation chamber. The first refrigerant pipe and the second refrigerant pipe are independent of each other. A regulating valve includes: a first regulating valve provided to the first refrigerant pipe, and a second regulating valve provided to the second refrigerant pipe.

Abstract: Provided is an electrical device. In a setting unit, a right-room temperature display unit displays a set temperature or the current temperature of a first housing room. A left-room temperature display unit displays a set temperature or the current temperature of a second housing room. A right-room temperature setting button is an operation unit for a user to switch the set temperature of the first housing room. A left-room temperature setting button is an operation unit for a user switch the set temperature of the second housing room. The set temperature difference between the first and second housing rooms is controlled to be within a prescribed value. When the set temperature of one of the first and second housing rooms is changed so that the set temperature exceeds a prescribed value, a microcomputer automatically changes the other set temperature so that the set temperature difference is within a prescribed value.

Abstract: A first authentication apparatus executes authentication of a person captured in an input image by comparing face feature information of the person being acquired from an input image, with registered face feature information in a first watchlist. A second authentication apparatus executes authentication of a person unauthenticated with the first watchlist by comparing face feature information of the face feature information for which matching registered face feature information does not exist in the first watchlist, with registered face feature information in a second watchlist. A host server includes a watchlist updating unit that updates registered face feature information in the first watchlist and registered face feature information in the second watchlist, based on at least one of a priority degree for each piece of registered face feature information in the first watchlist and a priority degree for each piece of registered face feature information in the second watchlist.
