Abstract: An AI control device, which identifies individual users from a plurality of users to receive input data, and is connectable to a server device that generates a trained model based on input data for each user, includes a control unit, and a communication unit connected to the server device. The control unit acquires input data, associates acquired input data and identifying information used to identify the user of the AI control device, and sends the data and information to the server device via the communication unit. The control unit uses the sent acquired input data to execute a trained model that is generated separately from trained models of other users by the server device, and that learns characteristics of acquired input data and detects input data having the same characteristics from unknown input data.

Abstract: This channel simulation device is provided with a memory for storing a distance calculation parameter and reception strength calculation parameter, and a processor for estimating desired-wave reception strength and interfering-wave reception strength on the basis of the distance calculation parameter and the reception strength calculation parameter. The desired-wave reception strength refers, for each set of two areas selected from a plurality of areas, to reception strength when a transmission signal transmitted from the wireless microphone of one area is received by a receiver in the one area. The interfering-wave reception strength refers to reception strength when a transmission signal transmitted from the wireless microphone of the other area is received by the receiver in the one area.

Abstract: An intercom exchange is connected to multiple terminals, and includes multiple communication paths, a digital switch circuit for switching connections between the terminals and the communication paths, and a CPU that controls the DSPs and the switch circuit. The CPU performs control for preferentially allocating a communication path to the first terminal, and the allocated DSP determines whether a sound from the first terminal that has been received as input via the switch circuit is an abnormal sound. Upon determining that the sound is an abnormal sound, the allocated DSP notifies the CPU, and upon receiving the notification, the CPU determines an alert destination based on the notification and performs alert processing for sending an alert to the alert destination.

Abstract: Resonant frequencies f2 and f3 detected in a resonant space are determined as center frequencies of a dip. Based on measurement values at a speaker and a microphone in the resonant space, a basic amplitude frequency characteristic Ca and a target amplitude frequency characteristic Cd are found. A smoothness degree on a frequency axis is larger in the target amplitude frequency characteristic Cd than the basic amplitude frequency characteristic Ca. A damping level and quality factor of the dip are determined based on a difference between the basic amplitude frequency characteristic Ca and the target amplitude frequency characteristic Cd in the center frequencies f2 and f3 of the dip and frequencies near the center frequencies.
