Abstract: An exacerbation risk prediction system predicts an exacerbation risk of a patient suffering from a respiratory disease. The exacerbation risk prediction system includes an oxygen concentrator that supplies oxygen to the patient through a cannula, an acquisition unit that acquires first information including biological information of the patient wearing the cannula on exertion and at rest and patient information regarding a disease state, a storage that stores the first information, a prediction unit that predicts the exacerbation risk based on the first information, and a learning unit that learns the first information and an evaluation regarding exacerbation in association with each other. The biological information is at least one of respiratory rate, respiratory waveform, and exhaled gas component amount. The biological information is acquired from the oxygen concentrator. The prediction unit predicts the exacerbation risk by inputting the first information to a learning model created by the learning unit.

Abstract: In an air conditioner using a power supply wiring connected between an outdoor unit and an indoor unit for communication between the indoor unit and the outdoor unit, noise transmitted from the power supply wiring to a power supply due to the communication is reduced. An indoor unit has power input terminals that receive power. An outdoor unit is connected to a first power supply and includes power supply terminals that supply power from the first power supply. In an air conditioner, in order to supply power from the outdoor unit to the indoor unit, in some cases, the power input terminal and a power supply terminal are connected by a first power supply line, and a first communication device and a second communication device are connected by a first signal line. In this case, the air conditioner has a first communication mode in which the first communication device performs a first wired communication by using the first signal line and the first power supply line, and the second communication device performs a second wired communication by using the first signal line and the first power supply line.

Abstract: An adsorber of an inside air control apparatus separates outside air into a first gas having a higher concentration of nitrogen and a lower concentration of oxygen and a second gas having a lower concentration of nitrogen and a higher concentration of oxygen. The inside air control apparatus performs a decrease operation and an increase operation. In the decrease operation, the first gas is introduced to an inside of a storage through a first gas passage so that a concentration of oxygen in inside air decreases. In the increase operation, the second gas is introduced to the inside of the storage through a second gas passage so that a concentration of oxygen in the inside air increases.
