Abstract: The notification optimization system includes: a first setting unit to which a first notification setting in a first time zone including noon is set, the first notification setting being selected from a plurality of notification settings; a second setting unit to which a second notification setting in a second time zone including twelve midnight is set, the second notification setting being selected from the plurality of notification settings; and a controller configured to perform a notification based on settings of the first setting unit or the second setting unit.

Abstract: A motorized bedding system includes: an acquisition unit that is capable of acquiring a setting of motorized bedding of each of users, a state of each of the users, and snoring detection information of each of the users; a computation unit that is configured to compute a sleep score based on the state of each of the users; a memory that is configured to store data including multiple sets of the setting of the motorized bedding and the sleep score associated with each of the multiple sets of the setting; and an output unit that is configured to output a recommendation setting of the motorized bedding based on the setting associated with the high-level sleep score among the multiple sleep scores stored in the memory, in which the motorized bedding system includes: a first mode where the system automatically changes the setting of the motorized bedding based on the state of each of the users; and a second mode where the system automatically changes the setting of the motorized bedding based on the snoring detect

Abstract: An object of the present invention is to provide a dissimilar metal joined material that has corrosion resistance that can prolong life resulting from corrosion and has a small difference from original characteristics. There is provided a dissimilar metal joined material including: a clad material including a high thermal expansion layer composed of an alloy containing Mn, and a low thermal expansion layer composed of an alloy containing Ni, the low thermal expansion layer being joined directly to the high thermal expansion layer or via an intermediate layer; and a corrosion resistant plating layer provided on at least a surface of the high thermal expansion layer, the corrosion resistant plating layer having a thickness of 10 nm to 120 nm.
