Abstract: A device 1 for measuring a propagation time of a sound wave comprises a sound source means 11 and a calculation means 12. The sound source means 11 outputs a time stretched pulse as a sound source signal input to a speaker 3. The calculation means 12 calculates a cross-correlation function of the time stretched pulse and the sound signal which is output from the speaker 3 and is received in a microphone 4. Based on the cross-correlation function, the propagation time of the sound wave between the speaker 3 and the microphone 4 is found.

Abstract: Receiving antennas 2a, 2b receive a digital modulated signal from a digital wireless microphone. The digital modulated signal comprises a carrier signal modulated with successively generated digital signal trains. A changeover switch 4 selects one of the antennas 2a, 2b in response to a selection signal. A high-frequency unit 8, a demodulating unit 10 and a decoding unit 12 receive and demodulate the digital modulated signal received by the selected antenna. Analog comparators 24a, 24b compare a reception level indicative signal from the high-frequency unit 8 with threshold values, and a diversity judging unit 28 changes the selection signal in accordance with the comparison result. The digital signal trains comprise a plurality of successive frames, and each frame includes an information data section, a preamble section preceding the information data section for establishing synchronization of the information data section, and a guard bit section succeeding the information data section. Each time the guard bit section is received, the selection signal is changed and the antenna selection is performed.

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.
