Abstract: An electrostatic atomizing apparatus includes a main body portion, a container, a first air flow path, a second air flow path, an electrostatic atomization unit, and an air flow generation unit. The container is detachable from the main body portion, is capable of storing a liquid, and includes a first ventilation hole and a second ventilation hole. The first air flow path includes a first end that includes an air suction port, and a second end that connects to the first ventilation hole. The second air flow path includes a third end that connects to the second ventilation hole, and a fourth end that includes an air exhaust port. The electrostatic atomization unit is disposed on the second air flow path. The air flow generation unit generates an air flow that causes air to flow through the first air flow path, through the container, and through the second air flow path.

Abstract: A management method manages a plurality of devices provided in a structure, a server includes storage storing operation information related to a plurality of devices and time information of a time at which it is expected that no one is present. The method specifies, for each device, operation times at which an operation is performed, operation information, specifying in-structure-absence times when it is expected that no one is present, both in accordance with the time information. For each device, time differences for the specified operation times are calculated. For each device, a performed certain operation is a behavior pattern correlated to a behavior when the person continues being present when a ratio of a frequency of the calculated time differences regarding the corresponding device, which is lower than a particular value, is equal to or lower than an other value.

Abstract: A noise reduction device is connectable to a plurality of sound acquisition devices and a plurality of control sound output devices for reducing noises in a given space where seats are arranged and a sound field can be formed. The device includes a sound receiver, a processor, a control sound transmitter. The sound receiver receives a sound signal from at least two of the plurality of sound acquisition devices. The processor detects a state change of the sound field, and generates a control sound signal for reducing noise with respect to the sound signal. The control sound transmitter outputs the control sound signal to each of control sound output devices. The processor acquires, for example, seat information for specifying the reclining state of a seat. The processor controls the generation of the control sound signal based on the change of state of the sound field including the seat information.

Abstract: In a noise reduction device that generates and outputs a control sound signal for reducing noise, an internal loop control unit controls an internal loop in which a pre-output control sound signal that is acquired from a control sound output unit before output to a speaker is input to a sound receiver. A measurement unit measures an input level of a microphone sound signal and an input level of the pre-output control sound signal that has been input to the sound receiver in the internal loop. A fault detector uses the input level of the microphone sound signal and the input level of the pre-output control sound signal measured by the measurement unit to detect a fault in any one of the microphone, the sound receiver, the speaker, and the control sound output unit. A transmitter sends a result of fault detection performed by the fault detector to a management device.

Abstract: A sound collecting system includes a plurality of sound collecting units that collect sound and a sound collecting device. The plurality of sound collecting units send sound collection data including audio data and time data to the sound collecting device. The sound collecting device includes a processor that manages time for the plurality of sound collecting units and receives an instruction specifying a sound collecting location, and an output unit. The processor of the sound collecting device synthesizes the audio data of the plurality of sound collecting units on the basis of the time data of the plurality of sound collecting units, and outputs, from the output unit, the audio data of the sound collecting location.

Abstract: A radar detection system according to the present disclosure is a radar detection system that detects an obstacle to an aircraft in an airport. The radar detection system includes a radar apparatus, and a control apparatus. The radar apparatus detects an obstacle by transmitting and receiving a radar signal, and acquires obstacle information regarding the obstacle detected based on the received radar signal. The control apparatus switches the operation of the radar apparatus according to the aircraft state of the aircraft. The control apparatus turns off the radar apparatus when the aircraft takes off, and turns on the radar apparatus when the aircraft makes a landing.
